Abstract
(EN)
A multi-beam LiDAR system (102, 300) is provided. The multi-beam LiDAR System (102, 300) includes a transmitter(202) having an array of laser emitters (310, 400). Each laser emitter is configured to emit a laser beam (201). The laser emitter array (310, 400) includes a first type of laser emitter board (4101, 4102, 4301, 4301, 5101, 5102) and a second type of laser emitter board (4201, 5201). The second type of laser emitter board (4201, 5201) includes two or more laser emitters. The second type of laser emitter board (4201, 5201) is not parallel to a predefined plane.

L'invention concerne un système LiDAR à faisceaux multiples (102, 300). Le système LiDAR à faisceaux multiples (102, 300) comprend un émetteur (202) comprenant un réseau d'émetteurs laser (310, 400). Chaque émetteur laser est conçu pour émettre un faisceau laser (201). Le réseau d'émetteurs laser (310, 400) comprend un premier type de carte d'émetteur émettrice laser (4101, 4102, 4301, 4301, 5101, 5102) et un second type de carte d'émetteur laser (4201, 5201). Le second type de carte d'émetteur laser (4201, 5201) comprend au moins deux émetteurs laser. Le second type de carte d'émetteur laser (4201, 5201) n'est pas parallèle à un plan prédéfini.
