Lidar system and method

A multiline LiDAR includes a rotor, a stator, a plurality of lasers, a light collimator arranged in the rotor, and one or more carriers arranged in the rotor. The plurality of lasers are arranged on the one or more carriers in n rows, n≥2, and lasers in different rows are staggered from each other....

Beschreibung
Zusammenfassung:	A multiline LiDAR includes a rotor, a stator, a plurality of lasers, a light collimator arranged in the rotor, and one or more carriers arranged in the rotor. The plurality of lasers are arranged on the one or more carriers in n rows, n≥2, and lasers in different rows are staggered from each other. The multiline LiDAR is configured such that, when detection light emitted by each laser is reflected by objects, reflected light is converged on a detector after passing through an optical receiver, and detection beams emitted by the plurality of lasers are configured to be driven by the rotor to scan around a central axis to generate a scanning point cloud having a sparse-dense distribution in a vertical direction to obtain information about objects in a central field of view. A number of lines of the multiline LiDAR is equal to or greater than 16.
