DJI Zenmuse L3 Star-Shaped LiDAR scanning: capturing ground under trees
See how the DJI Zenmuse L3's Star-Shaped LiDAR scanning mode captures a robust ground surface beneath dense woodland canopy, and when to use it.
Surveying ground under woodland? Your scan mode matters more than you might think.
This ground data was captured with the DJI Zenmuse L3 in Star-Shaped scanning mode, beneath dense tree canopy. The result is a robust ground surface, with very few gaps.
Tip: if the video doesn't play in high resolution automatically, click the settings cog and select the highest quality available.
The curved lines and petal-like loops in the video aren't noise. They're the scan pattern, showing how each patch of ground is hit from many different angles. More angles mean more chances for pulses to find gaps through the leaves and reach the ground.
The pattern is easiest to see on open ground. Under the trees fewer pulses get through, but the multiple angles help fill in more of the woodland floor.
Which DJI Zenmuse L3 scan mode should you use?
Linear: More consistent point distribution, ideal for high-accuracy terrain mapping.
Star-Shaped: Balances accuracy with multiple scan angles and penetration, well suited to forests and dense urban environments.
Non-Repetitive: Multiple scan angles and broader coverage, optimised for power line inspections and complex structural surveys.
If ground points under vegetation are the goal, Star-Shaped is the one to fly.
The DJI Zenmuse L3 is compatible with the DJI M400 drone.
