LiDAR Description
The L2 features two point cloud scanning methods. Users can choose between non-repetitive
and repetitive scanning methods.
Non-repetitive scanning pattern: the non-repetitive scanning pattern provides a near-
circular FOV with a scanning density that is denser in the center of the FOV compared to the
surrounding area, resulting in a more comprehensive point cloud model.
Repetitive scanning pattern: the repetitive scanning method provides a flat FOV, which is
similar to traditional mechanical scanning methods. It can obtain more uniform and precise
scanning results compared to traditional mechanical scanning methods.
Non-repetitive Scanning Method
For the non-repetitive scanning method, the L2 has a horizontal FOV of 70° and a vertical FOV of
75°.

and the aircraft is hovering.
Figure B: the point cloud patterns after 10 s recording by the L2 that is installed on the aircraft.
The relative altitude is set to 150 m and the ight speed to 10 m/s.
Repetitive Scanning Method
For the repetitive scanning method, the scanning repeats approximately every 0.02 s, the
horizontal FOV is 70° and the center of the vertical FOV is 3°.
