Problems solved by technology

Theoretically, the more laser beams emitted by the multi-line lidar, the more comprehensive the description of the environment. However, the height of the multi-line lidar is limited by the height of the components and cannot be made very small, so the unit height cannot be infinitely increased. harnesses, thus not being able to achieve higher vertical resolution
[0004] It can be seen that the vertical resolution of the multi-line lidar scanning in the prior art is not high

Abstract

The embodiment of the invention discloses a laser radar and a laser radar control method. The laser radar comprises a first group of laser emitting units for emitting a first group of emergent laser, a first transmitting end collimating unit for collimating the first group of emergent laser, a second group of laser emitting units for emitting a second group of emergent laser and a second transmitting end collimating unit for collimating the second group of emergent laser. Therefore, the vertical resolution of the laser radar can be improved and the size of the laser radar can be reduced.

Description

technical field [0001] The invention relates to the detection field, in particular to a laser radar and a laser radar control method. Background technique [0002] Lidar is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of the target. Its working principle is to first transmit the detection laser beam to the target, and then compare the received signal reflected from the target with the transmitted signal. After proper processing, the relevant information of the target can be obtained, such as target distance, azimuth, height, speed, attitude, and even shape and other parameters. [0003] Multi-line laser radar is a kind of laser radar. The multi-line laser radar in the prior art emits laser light through a semiconductor laser transmitter, and the passing motor rotates to form a scanning of multiple line beams and detect the echo optical signal. . Theoretically, the more laser beams emitted by the multi-line lidar, t...
