Problems solved by technology

However, for a multi-line lidar with a small vertical field of view, the detection distance of its laser beam is relatively long, resulting in the short-distance area around the multi-line lidar being unable to be detected, and there is a short-range detection blind spot

Abstract

The invention discloses a laser radar system and driving equipment, and relates to the technical field of laser radars. The laser radar system comprises a multi-line laser radar and a reflecting plate, and the multi-line laser radar is used for emitting a plurality of laser beams; the reflecting plate is arranged on one side, deviating from a to-be-detected plane, of the multi-line laser radar, and is used for reflecting at least one target laser beam located on one side, deviating from the to-be-detected plane, of an optical axis of the multi-line laser radar to the to-be-detected plane, the detection distance corresponding to at least one target laser beam is smaller than or equal to a preset obstacle avoidance distance, and the at least one target laser beam is an edge laser beam. The laser radar system provided by the invention can realize short-distance obstacle avoidance and reduce a detection blind area.

Description

technical field [0001] The present application relates to the technical field of laser radar, in particular to a laser radar system and driving equipment. Background technique [0002] At present, the optical axis of the multi-line lidar is usually set parallel to the horizontal direction, and the offset of the vertical field of view is set to 0 degrees. However, for a multi-line lidar with a small vertical field of view, the detection distance of its laser beam is relatively long, resulting in the short-distance area around the multi-line lidar being unable to be detected, and there is a short-range detection blind spot. Contents of the invention [0003] The application provides a laser radar system and driving equipment to reduce the short-distance detection blind area of ​​the laser radar system and realize short-distance obstacle avoidance. [0004] This application provides: [0005] A lidar system comprising: [0006] multi-line lidar for emitting multiple laser ...
