Abstract
(EN)
A scanning angle adjusting device, a laser radar system, a vehicle and an automatic correction method. The scanning angle adjusting device comprises: a second direction driving mechanism (20), connected to a laser radar (3), and used for driving the laser radar (3) to rotate around a second axis (23) extending along a second direction; and a first direction driving mechanism (10), connected to the second direction driving mechanism (20), and used for driving the second direction driving mechanism (20) to rotate around a first axis (14) extending along a first direction, the second axis (23) being perpendicular to the first axis (14).
(FR)
La présente invention porte sur un dispositif de réglage d'angle de balayage, sur un système radar laser, sur un véhicule ainsi que sur un procédé de correction automatique. Le dispositif de réglage d'angle de balayage comprend : un second mécanisme de commande de direction (20), relié à un radar laser (3) et utilisé pour entraîner le radar laser (3) à tourner autour d'un second axe (23) s'étendant le long d'une seconde direction ; et un premier mécanisme de commande de direction (10), relié au second mécanisme de commande de direction (20) et utilisé pour entraîner le second mécanisme de commande de direction (20) à tourner autour d'un premier axe (14) s'étendant le long d'une première direction, le second axe (23) étant perpendiculaire au premier axe (14).
