DJI Terra Case studies

Use The DJI Ecosystem For An End-to-End Aerial Mapping Workflow.

These exclusive data sets created by heliguy™ show the qualities of DJI Terra as a software processing tool.

We collected the data using the DJI Zenmuse P1 photogrammetry camera and DJI Zenmuse L1 LiDAR and RGB payload, both integrated with the DJI M300 RTK drone.

Our data sets highlight the capabilities of using the DJI ecosystem for an end-to-end drone surveying workflow.

DJI Terra For Photogrammetry

Using the DJI Terra, P1, and M300 RTK combination:

  • DJI Terra produced sharp and realistic 3D models, with clear and intricate details;
  • The 2D orthomosaic was just as crisp - even enabling us to count the number of holes in bricks on the ground when zooming in to the map, taken from 80m flight height; 
  • Easy-to-use measurement and analysis tools, such as surface area and volume calculations, and coordinates; 
  • DJI Terra is a locally-based software, so no photo upload was required. Uploading only comes into play when working on a cloud-based platform. It took us just over eight hours to process 390 images.

DJI Terra For Drone LiDAR

Using the DJI Terra, L1, and M300 RTK combination:

  • Rapid processing - it took us just three minutes to process data from a 30-minute mission;  
  • Terra created a robust point cloud model, which would have been even more defined with a reorientation of the gimbal;
  • DJI Terra helped to identify intricate details on the survey site, such as powerlines.
  • Terra supports a range of colour modes, including visible, reflectivity rate, and return numbers.

3D Modelling: DJI Terra Vs Pix4Dmapper

Enhanced Detail With DJI Terra

One of the most impressive aspects of DJI Terra is its ability to build sharp and realistic 3D models - especially when used in conjunction with the high-resolution 45MP full-frame P1 camera. In many ways, it is bordering on reality capture. Such robust data sets are valuable for people who are utilising 3D models for decision-making and information sharing, especially for operations which require intricate details, such as crime-scene investigation.

The 3D modelling capabilities of DJI Terra are further endorsed when comparing to an alternative software; in this case, Pix4Dmapper.

The following examples highlight the differences. Both were captured during autonomous missions, each during a single flight, with the M300 RTK and using the P1 camera's Smart Oblique Capture mode - which captures only essential imagery. Adding manual data capture to supplement the initial flight would further enhance these models across both software platforms.

Farm Buildings And JCB

This first example of some farm outbuildings and a digger shows the difference in detail between the models in the two software packages.

The 3D reconstruction via DJI Terra is very intricate.  

The shed is replicated in its entirety, with nice clean, clear edges, and no distortion or warping. Meanwhile, the map has enough detail to enable the viewer to clearly see the items in the shed to the right of the image.

In the foreground, the JCB is razor-sharp: Even the cab has been replicated in extremely clear detail.

The second image - while not a bad model - is not as clear as the DJI Terra data set: The building facades are slightly distorted, the items in the shed are more difficult to distinguish, and the JCB - with its blurry cab - almost appears to be melting into the ground.

Farm House

This second example further demonstrates DJI Terra's 3D modelling capabilities.


The DJI Terra model of the farm house is sharp and higher-resolution.

This in turn helps to pick out the small details. Note, for instance, how the Terra data set has replicated the three chimneys, giving the structures texture and shape and highlighting their intricate features. Meanwhile, you can clearly see the letter box, widows and even the door knob on the front door.

In comparison, the alternative software is unable to replicate these fine details. Again, it's not a bad model, but the chimneys are more blocky, with minimal texturing. And while the letter box can be distinguished, the front door is missing the windows and door knob.


Streamlined survey missions.

Utilise a suite of tools for accurate data capture

Streamline your surveying missions with DJI Terra, which provides seamless workflows and accurate results.

DJI Terra allows you to create highly detailed 2D orthomosaic and 3D models with enhanced absolute accuracy by setting Ground Control Points (GCPs) and checkpoints. This ensures you can measure and inspect easily and efficiently and builds reliable representations of our asset, objects and surroundings.

To ensure the results meet the required accuracy, view a quality report of your mission, and convert the coordinates of your maps and models into 8500+ major coordinate systems.

Through DJI Terra, incorporate POS data, GCPs, or both data sets to create georeferenced maps and models.

To help you collect accurate data and build detailed maps, DJI Terra has a range of mission plans, mapping features, and analysis tools, to aid automated missions, rapid data collection, and onsite analysis.

For these reasons, DJI Terra can benefit multiple industry applications.

  • Construction/Infrastructure: Collect data for measurements and analyse of your job site to bolster decision-making and collaboration, and perform inspections of complex assets and structures.
  • Energy: Conduct inspection of utilities, safely and efficiently. DJI Terra's Electricity licence has special optimisations for powerlines.

These waypoints have lots of adjustable parameters including altitude, gimbal pitch angle, speed, heading and more.

For even more complex flights - use 3D Flight Visualisation to simulate the flight on an existing 3D model before starting your mission.

Area Missions

With just a few simple taps you can totally automate flights over a specific area.

Using as little as three points you can create an area on a map that you would like to capture data from. 

DJI Terra will automate the flight path for the mission, giving you access to accurate imagery which can be used to produce maps and 3D models.

Oblique Missions

Use Oblique mission planning for even more accurate data collection. 

This type of mission is recommended when accuracy and small details are essential to the operation.

You can capture rich 3D model data by adjusting the camera angle during flight, giving a fully detailed model of the asset.

Corridor Missions

Simply draw a line on the map to create automated flight missions around roads and railways.

Tailor your flight and tweak the mission settings to change the total area mapped.

This provides flexibility to choose between creating high-definition 2D maps and 3D models, or quick overviews. 

Detailed Inspection

Detailed inspection mission planning enables automated inspection workflows.

Select one or more points in a local 3D model or point cloud to generate waypoints and flight routes.

Enhance waypoint selection and flight route planning through a simulated camera view, displayed on screen and including the selected point.

Phantom 4 RTK And DJI Terra FAQs

The DJI Phantom 4 RTK is a low-altitude mapping solution which integrated with DJI Terra.

What should I do to ensure accuracy in my missions when collecting data with the Phantom 4 RTK?

  1. Conduct your missions in clear weather conditions with high visibility.
  2. Check the images and videos for brightness and clarity immediately after your mission.
  3. During a surveying mission, avoid areas with strong electromagnetic interference or obstructions to ensure the accuracy of the attitude algorithm of the Phantom 4 RTK. Also make sure that the remote controller is properly linked to the aircraft.
  4. Ensure there is enough forward and side overlap. It is recommended to have a forward overlap rate of 80% and a side overlap rate of 70%. Overlap rates can be adjusted depending on the terrain.

When I connect DJI Terra to Phantom 4 RTK, the app tells me that I cannot take off because the RTK signal is too weak. What should I do?

It could be that you are operating somewhere with a lot of signal interference or obstructions, which affects the strength of the RTK signal. 

Try turning off the RTK module and take off manually with the GNSS positioning. Once the drone reaches a height where there is less interference, you can turn on the RTK module and connect to DJI Terra to conduct your flight missions.

What is the accuracy when building 2D maps and 3D models with the Phantom 4 RTK?

When using the Phantom 4 RTK, the absolute accuracy achieved by the 2D maps in DJI Terra is around 1 to 2 times the GSD, which is a similar level of accuracy as other data processing software. 

When flying at 100m height, the absolute horizontal accuracy of the 2D map is 2-5cm, and the absolute accuracy of the 3D models is within 4cm.

Zenmuse L1 And DJI Terra FAQs

Combine the L1 with the M300 RTK and DJI Terra for an integrated, complete solution for accurate real-time 3D data acquisition.

Once you have the data you need, use DJI Terra for a one-stop post-processing solution. DJI Terra seamlessly fuses the IMU and GNSS data for point cloud and visible light calculations, in addition to conducting POS data calculations, helping you to effortlessly generate reconstructed models and accuracy reports.

Zenmuse L1 LiDAR Point Cloud Process - Help And Advice

Do I need to purchase a license to use the DJI Terra LiDAR to process point cloud?

No, LiDAR point cloud is a free feature, but if you need to use the point cloud accuracy optimisation feature, you need to purchase the license for the professional version or higher.

Does LiDAR point cloud mission create 3D models?


Which data should be imported when doing the LiDAR point cloud process?

Imported folders must include LiDAR point cloud data, RTK data, IMU data, whereas JPEG data can be imported when needed (select the folder named after data collection time).

What is the point cloud effective distance? How do I set up a point cloud effective distance? Under which scenes do I need to set up?

  1. Point cloud effective distance: The point cloud that exceeds the distance from the LiDAR will be filtered during post-processing.
  2. How to set up a point cloud effective distance: Estimate the maximum straight-line distance between the location of LiDAR and the corresponding target area when collecting data.
  3. Under which scenes to set up: When reconstructing a closer measuring area, and when distant background areas are inevitably collected, you can set up an effective distance to get a better result for point cloud.

What is point cloud accuracy optimisation? When do I need to turn on point cloud accuracy optimisation? After it is turned on, what changes would there be for processing quality and time?

  1. Point cloud accuracy optimisation: Optimise point cloud data scanned at different times to make the overall point cloud accuracy higher.
  2.  When to turn on point cloud accuracy optimisation: When it is off, if the results contain obvious layer malposition, turn on the point cloud accuracy optimisation feature to fix the problem.

What is the default output coordinate system? Can I modify the coordinate?

The default coordinate system is WGS84 and can be modified.

How do I process a point cloud file when it is too large?

You are recommended to separate it into multiple tasks for processing.

What does the value of the Colorbar reflectivity mean? And what would be the range?

The reflectivity of the measured target is between 0 - 255, where 0 to 150 correspond to the reflectivity within the range of 0 to 100% in the Lambertian reflection model; 151 to 255 correspond to the reflectivity of target objects with retroflection properties.

What information does LAS file record?

The 3D coordinates, RGB color, reflectivity, GPS timestamp, number of returns, the actual return number, and scanning angle of the points are recorded, along with the total number of points corresponding to each return, the software and version corresponding to the generated results, and the geographic coordinate system.

What output formats of the files does LiDAR point cloud process?

.pnts, .las, .s3mb, .ply, and .pcd

Zenmuse P1 and DJI Terra FAQs

DJI Terra syncs effortlessly with DJI’s flagship surveying camera payload, the P1; offering detailed and accurate 3D models and measurements.

Zenmuse P1 Calibration

How should I design the calibration route and set parameters? Is RTK required for route collection?

The calibration route can be designed using 5-heading tilt-shift photography or traditional 5-route oblique photography.

To achieve a more reliable calibration result, the following parameters are recommended:

  • Capturing no less than 500 images
  • The front overlap is no less than 80%
  • The side overlap is no less than 70%
  • The proportion of oblique images is not less than 2/3
  • A calibration scenario with a large elevation difference area

RTK is not required, but the quality of calibration results can be verified through RTK in connection with checkpoint layout.

After reconstruction is complete, how do I check whether the route data meets the calibration standard?

If RTK positioning data is available for calibration route collection, the accuracy of checkpoints can be verified based on the results of the calibration route reconstruction by deploying checkpoints in the survey area. If the accuracy meets the required engineering accuracy, the calibration meets the standard.

If no RTK positioning data is available for calibration route collection, it is impossible to quantitatively evaluate whether the calibration result meets the standard. 

However, this can be verified based on the difference between the initial value and the optimised value of camera parameter focal length f and principal points cx, cy for oblique photography reconstruction after camera calibration. If there is no significant difference, the calibration can be considered as meeting the standard.

How often should the load device be calibrated?

How often the load device should be calibrated depends on actual use. 

It is recommended to calibrate the camera using the latest reconstruction calibration file when there is a significant difference between the initial value and the optimised value of camera parameter focal length f and principal points cx, cy in the reconstruction quality report, and the reconstruction result meets the engineering accuracy requirements.

P4 Multispectral and DJI Terra FAQs

Import data from the DJI Phantom 4 Multispectral into DJI Terra for multispectral reconstructions. 

2D Multispectral Reconstruction

Does the 2D Multispectral Construction mode also support data from other multispectral cameras other than the P4 Multispectral?

Currently, no.

Can I create 2D multispectral reconstructions without importing RGB images?

No. Currently RGB images are required for 2D multispectral reconstructions.

Can images of a particular band captured by P4 Multispectral be imported into DJI Terra for 2D multispectral reconstruction?

Yes. You only need to import RGB images and images within the bands required by a particular vegetation index to perform a reconstruction.

Is radiometric correction supported by 2D multispectral reconstruction?

Yes, before reconstruction, calibration data can be imported for radiometric correction.

How many sets of calibration board data are supported for radiation calibration?

Up to three sets of calibration board data are supported.

Cluster Reconstructions - FAQs

What computer equipment configuration is required for cluster reconstruction?

Please refer to Preparation Before Using DJI Terra.

How can I set up a local area network (LAN)?

Please refer to Preparation Before Using DJI Terra.

What is the maximum number of photos that can be processed through cluster reconstruction?

Depending on the highest computer RAM configuration, 1GB of free RAM can handle 8 gigapixels of data (approximately 400 Phantom 4 RTK images).

What is a control device? What is a worker device?

Each computer connected to a local network is either a control device or a worker device. A control device assigns reconstruction missions (and also undertakes part of the computing work), while reconstruction algorithms run mainly on worker device.

Do control devices need to be bound with a license?


Do worker devices need to be bound with a license? Can worker devices be replaced?

Binding is not necessary. Worker devices can be replaced as needed.

Can control devices be turned on at the same time in the same local area network (LAN)?


Can the number of worker devices be increased after the cluster version license is activated?

Yes. For details, please refer to Preparation Before Using DJI Terra.

Which software should be used to open worker devices?

DJI Terra Engine

What is the purpose of the Shared Directory?

It is used to store original image data, temporary outputs and reconstruction outputs.

Does aerotriangulation support cluster reconstruction?

Currently supported during the feature point matching phase. Other phases will be computed using the worker device with the highest RAM.

How can I view the working status of worker devices?

The reconstruction mission list displays the status of the worker devices currently participating in the reconstruction.

How control device assign the work of worker devices during cluster reconstruction?

Aerotriangulation: Automatically selects the worker device with the highest RAM to perform the aerotriangulation missions;

Block reconstruction: When the number of blocks is larger than the number of worker devices, the worker devices will be used to the maximum extent.

In cluster reconstruction, can a worker devices participate in the current reconstruction mission again after being restarted or released?

No. To enable a restarted or released worker devices to participate in the current reconstruction mission, you can stop the mission and re-select the devices before continuing reconstruction.

Why is the utilisation rate of integrated graphics cards on worker devices higher than that of discrete graphics cards during reconstruction?

Temporarily not to the step of using a discrete graphics card (integrated graphics cards are not used for computing on DJI Terra).

The following prompt appears when opening the software: “Unable to continue code execution because MSVCR120.dll could not be found. Reinstalling the program may resolve this issue.”

Download and install the application:

No worker device can be found in the Local Network Worker Devices list.

  1.  Ensure that the Shared Directory of the control devices and worker devices are consistent and the paths are accessible;
  2. Close the antivirus software and security software, then try searching again;
  3. Disable the firewall of the control and worker devices.
  4. Try searching again after disabling the virtual network card (Network Settings → Change Adapter Option → Disable Networks Started with Hyper-V).

There are already aerotriangulation results and the photos are stored on the local disk. Will it go through aerotriangulation again if using cluster to do point cloud or model reconstruction?

No, the photos and existing aerotriangulation results will be automatically copied to the network-attached storage (NAS) for cluster reconstruction.

This prompt occurs for a worker device: “Script error.”

1: First, check if you are using software such as Microsoft OneDrive, Outlook, Microsoft Teams and Flash. The software can be uninstalled if not needed;

2: If it is needed, you can try:

  1. (1) Updating the above software
  2. (2) Updating the Win10 system
  3. (3) Updating the driver
  4. (4) Performing the setting: IE security policy-allow dynamic scripts
  5. (5) Performing the setting: IE advanced settings-reset

Will any problem with a single device affect the reconstruction mission?

A single worker device error will not cause the reconstruction mission to fail. Any failed worker device mission will be redistributed by the control device. If the redistributed worker device also has errors, the reconstruction mission will fail.

Do cluster missions support resuming from a breakpoint?


Where can I get the logs of cluster reconstruction missions?

  1. In the control device, open DJI Terra, press Ctrl+Alt+L, find all logs for the corresponding time period of the failed mission in the folder and export the logs;
  2. Under the shared directory, find all logs of the log folder [slaves_log] corresponding to the mission and export them;
  3. SDK_log.txt in the models (3D) or map (2D) folder in the cache directory of that mission.

Why are all worker devices in the preparing state at certain stages of reconstruction, while some worker devices are in the working state and the others in the preparing state at certain other stages?

The reconstruction process is divided into several stages which should be carried out in sequence. Some stages are completed independently on the control device, at which point all worker devices will be in the preparing state.

Some stages are split into multiple missions which are then assigned to the worker device for processing. The worker devices that have completed the missions assigned will be in the preparing state, and will enter the next reconstruction stage after the other worker devices have also completed their processing.

Can third-party point cloud files be imported into DJI Terra?

Yes, LAS point cloud files can be imported.

Can a third-party LAS point cloud file be imported if it does not contain a coordinate system?

Yes. You should set the coordinate system when you first import the file. If the file uses an arbitrary coordinate system, you need to correct it using third-party point cloud correction software.

What are the important things to take note of when planning or executing a detailed inspection mission?


1. Make sure the RTK data sources are consistent when planning or executing a flight path;
2. Flight paths can only be executed when the RTK is in FIX status. During execution, you may set the first waypoint as the hovering inspection point. The mission must be stopped if the location of the inspection point is incorrect.
Why are there five flight routes when I plan an Oblique Mission in DJI Terra?

DJI Terra’s Oblique Mission uses five flight routes to capture the same amount of data as using five cameras simultaneously on a drone. The five flight routes correspond to the five camera headings – downward, forward, backward, left and right.

How do I plan flight routes when there is no internet connection and the map cannot be loaded?

If you have access to a mobile device that has an internet connection (such as a cellphone), you can turn on the hot spot so that the laptop can be connected to the internet. 

If the site where you are operating has no internet signal, you can pre-plan the flight route while you are indoors and have an internet connection, or manually fly the drone around the area to be mapped to set boundaries points to plan flight routes.
What is Ground Sample Distance (GSD)?

In photogrammetry and remote sensing, ground sample distance (GSD) in an aerial digital photo (such as an orthophoto) of the ground is the actual distance on the ground captured as represented by pixels. The unit is cm/pixel.

In the Mapping Mission page, what does Relative Height in Advanced Settings mean? How is it different from Mission Altitude in Basic Settings?

Relative Height in Advanced Settings is the height of the takeoff point relative to the area being mapped. Mission Altitude is the height of the drone relative to the area being mapped, which is also how ground sample distance (GSD) is calculated.

When do I have to adjust the Relative Height in Advanced Settings?

When there is a large difference between the elevation of the takeoff location and the elevation of the area being mapped, you can adjust the Relative Height in Advanced Settings to ensure that the Mission Altitude is determined considering the elevation of the area being mapped. 

For instance, if the drone takes off from a 50m building and the expected altitude for aerial data collection is 100m, you can set the Mission Altitude in Basic Settings to 100m, and Relative Height in Advanced Settings to 50m.
When should I adjust the overlap rates based on the terrain?

t is recommended to have a forward overlap rate of 80% and a side overlap rate of 70%, which should meet the requirements for most application scenarios. 

The overlap rate can be increased when the area being mapped has a large difference in elevation to ensure the highest point mapped has enough overlap. 
When the area mapped is relatively uniform in elevation, the overlap rate can be adjusted lower to reduce the amount of data that needs to be processed, making the mapping mission more efficient. 
However, it is recommended to keep the forward overlap at a minimum of 65% and side overlap at a minimum of 60%.
Which aircraft support real-time 3D mapping?

Phantom 4 RTK (Remote Controller), Phantom 4 Pro V2.0, Phantom 4 Pro + V2.0. Note: point clouds may be of poor quality or be unavailable in environments without RTK signals.

Why is my computer stuck when processing images locally to reconstruct a model? Can I run DJI Terra while running other programmes?

To build reconstruction models as quickly as possible, DJI Terra uses all the computer resources available, including the CPU, RAM, and VRAM of the graphics card, which could make the computer slower while running DJI Terra but should not be a problem once the processing is finished.

It is recommended that you don’t run other programmes that might be GPU-intensive while running DJI Terra, as doing so could result in failure of model reconstruction.
What are the Field, Urban, and Fruit Tree Scenarios in 2D Map?

The Field Scenario is designed to capture data from a relatively flat land, for example rice or wheat fields. 

The Urban Scenario is designed for areas with buildings of different heights. 
The Fruit Tree Scenario is designed for orchards that might have a large variation of elevations and heights. 
The 2D mapping algorithms are optimised for the three specific scenarios, so you can choose the one that best fits your mission type.


Why is there a large discrepancy between the elevation result in the digital surface model (DSM) of the 2D map generated by DJI Terra and the actual elevation measured via RTK?


The location information on aerial images collected by a drone that’s not equipped with RTK is not the most accurate, which will result in a difference between the elevation in the digital surface model (DSM) and the actual elevation.
When conducting missions with the Phantom 4 RTK, if the 2D map is generated with only the Nadir view images collected, the precision of the DSM will be limited, which is why it is recommended to incorporate oblique imagery in building the 2D map to enhance precision. This can be done by setting the gimbal pitch to -45° and circling the point of interest during flight.


What is the difference between 3D Reconstruction in Mapping Mission and in Oblique Photography Mission?

There is no difference. If only Nadir view images are available, it is recommended to use a mapping mission for building 2D maps. If oblique photos are available, you can choose an oblique photography mission.

How different are the 3D models built at different resolutions? How long does it take to build models at these resolutions?

There are three options for reconstruction resolution: high, medium, and low, which will generate models at full, half, and quarter resolution respectively. The higher the resolution the better the quality of the reconstructed models. The rough ratio of time consumption for reconstruction at high:medium: low resolutions is about 16:4:1.

Why are there gaps in my model? What are some factors that affect the quality of the reconstruction?

Gaps in the model can be due to missing shots of the area being mapped, or images taken at poor angles. The quality of reconstruction can be affected by factors such as reflective surfaces in the area (water or glass), or large areas of the same colour or pattern (white walls, skies).

Can DJI Terra crop 2D and 3D models?

Yes, this can be achieved before reconstruction. After aerial triangulation optimisation is complete, crop 2D and 3D models by specifying the reconstruction area using the ROI modeling function.

What files can I get from the 2D maps and 3D models built in DJI Terra?


2D reconstructions:
Results include map tiles shown in the app’s interface, digital orthophoto maps, and digital surface models in the GeoTIFF format used in UTM projections.
3D reconstructions:
Results contain a level of detail model in .osgb, .b3dm, or .s3mb, texture mesh in .ply, .obj, or .i3s, a point cloud in .pnts, .las, or .s3mb, and an aerial triangulation result file in .xml or Terra's own format..
How do I view the results and files from my aerotriangulation results, 2D maps and 3D point cloud or models?


You can click the Open folder button in each Mission to open the file folders where the files generated from the missions are stored. Aerotriangulation results are stored under "AT", 2D maps are stored under “map” and 3D point cloud or models are stored under “models”.
To view log files of reconstruction mission using Standalone computation, use Ctrl + Alt + L.


What variables might affect the accuracy of the 2D and 3D reconstructions in DJI Terra?

The accuracy of the reconstruction can be affected by factors such as camera distortion, image quality, flight height, side and forward overlap settings, GPS (RTK) positioning accuracy and the area’s texture information.

Can I run multiple missions on the same computer?

Due to limitations in the computer’s processing capacity, you can only run multiple reconstructions at the same time. They will be processed in the order in which they are added to the lineup.

What should I keep in mind when creating reconstructions using images taken by an oblique camera array?
You will need to define the camera parameters of each of the five cameras. The captured photos will be stored in five folders corresponding to each lens.
In a folder, select all photos, right-click and go to Properties, click Details, scroll down to Camera Model, double-click the parameter value box on the right to go into edit mode, enter numbers or letters. Do this in all five folders for the five camears, the names should be different for each camera, for example it can be set to: 1, 2, 3, 4, 5 or A, B, C, D, E.


Can I create 2D multispectral reconstructions without importing RGB images?

No. Currently RGB images are required for 2D multispectral reconstructions.

Can I import models generated in DJI Terra into other software programs, such as Maya, Blender, SketchUp and 3ds Max?

Yes, the .obj files generated in DJI Terra can be imported into Maya, Blender, SketchUp, and 3ds Max. Look up tutorials for the specific process for each software.

Can I embed a 3D model into a webpage?

Yes, .b3dm, .osgb, and .ply files generated by DJI Terra are universal file formats and can be embedded into webpages. You can find instructions for embedding each of these formats online.

Can I use non-aerial images to build 2D or 3D models?

Theoretically they can be used to reconstruct 3D models although the quality might suffer. They cannot be used to build 2D reconstructions.

Can I process images taken from non-DJI drones in DJI Terra to build 2D and 3D reconstructions?


Theoretically yes for 3D models, but the results might not be as good as if you were to use DJI drones.
The quality of the reconstructions will benefit from GPS or RTK positioning data on the images. 2D reconstructions are not supported.
