LiDAR Point Cloud Description
The L1 features two point cloud scanning methods. Users can choose between non-repetitive and
repetitive scanning methods.
A. The non-repetitive scanning method is the L1’s unique LiDAR technology. It 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.

Non-Repetitive Scanning Method
Typical Point Cloud Patterns
For the non-repetitive scanning method, the L1 has a vertical FOV of 77.2° and a horizontal FOV of
70.4°. The gure below displays the typical point cloud patterns of the L1 after 0.1 s, 0.2 s, 0.5 s, and 1 s.
A. Within a radius of 10° of the center of the FOV, the point cloud density rivals traditional 32-line
LiDAR sensors within 0.1 s.
B. Within a radius of 10° of the center of the FOV, the point cloud density rivals traditional 64-line
LiDAR sensors within 0.2 s. The point cloud density in the rest of the FOV rivals traditional 32-line
LiDAR sensors within the same time.
C. Over time, the point cloud density and coverage inside the FOV increase signicantly and reveal
more detailed information of the surroundings.
B. 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.
