LiDAR emits thousands of laser beams in various directions within a short time through its rotating or scanning mechanism.

Different materials have different reflectivity to laser light.When the LiDAR completes one scanning cycle, all the collected points form a point cloud.The raw point cloud data must be processed in a computing unit (such as a vehicle domain controller or a computer) to generate the intuitive 3D visual displayed on the screen.
