Zenmuse L1 LiDAR Workflow Training
DJI Zenmuse L1: End-to-end Surveying Workflow Training.
Free-to-watch surveying course, dedicated to the DJI Zenmuse L1 LiDAR and photogrammetry payload. Scroll down to access the course.
Featuring more than two hours of video content, including on-screen demonstrations, the material is presented by the heliguy™ in-house surveying team. A course handbook is also available after accessing the course.
The course was created by heliguy™ and DJI has since purchased the course licence to share to a global audience.
The course includes:
- Workflows for obtaining positional corrections;
- Assembly and connection to the DJI D-RTK 2 Base Station;
- LiDAR theory;
- Best L1 parameters;
- Mission Deployment: Topographical surveying, oblique scanning, corridor mapping and terrain follow;
- IMU calibration;
- Employing ground control for LiDAR data sets;
- Post-processing in DJI Terra and TerraSolid, including classification
#1 Module 1
Introduction to DJI Zenmuse L1
Before collecting data, it is very important to understand Zenmuse L1's capabilities and how the payload functions.
In the first module, you'll become familiar with the payload and have a basic understanding of the technical specs of both the hardware and software.
#2 Module 2
Generating and Applying Accurate GNSS positions using DJI Zenmuse L1
Learn the fundaments of GNSS RTK, including retrieving and analyzing data, obtaining data in real-time using the DJI D-RTK 2 mobile base station, and more.
#3 Module 3
The Basics of LiDAR Technology
In this module, we'll focus on the fundamentals of LiDAR technology with specific emphasis on the technical parameters of Zenmuse L1. By the end of the module, you'll know how to set parameters for multiple mission types, and different methods to successfully calibrate L1's IMU.
#4 Module 4
How To Collect Data Using DJI Zenmuse L1
In this module, you will learn how to successfully complete a survey mission, how to assess data that's been collected, and proven workflows that you can use when using DJI Zenmuse L1.
#5 Module 5
Generating Point Clouds Using DJI Terra
In this module, we'll introduce DJI Terra and go through the different processing methods available. By the end of the module, you'll know how to generate a 2D orthophoto map from raw images captured by the L1 and how to generate cloud points.
#6 Module 6
How To Generate DTMs using TerraSolid
In the final module of this learning series, you'll learn how to classify and clean point clouds in TerraSolid successfully. We'll show you how to export raw LiDar data successfully from DJI Terra to Terrasolid. By the end of this module, you'll know how to classify point clouds and generate DTMs, how to compare cloud points to get true coordinates, and more.
The outputs generated from this course can also be exported to other mapping software such as ArcGIS Pro or QGIS for further data manipulation.
