Problems solved by technology

The transmitting circuit device of the laser transmitter is relatively complex and the volume is large, so it cannot be stacked in sufficient quantities in a small range. The stacked number of laser transmitters in a unit range determines the number of laser lines emitted in a unit range, that is, the laser The stacking number of emitters is an important factor affecting the vertical resolution of multi-line lidar, so the vertical resolution of multi-line lidar in the prior art is still low
[0004] It can be seen that the existing multi-line lidar is bulky and the vertical resolution is not high

Abstract

The embodiment of the invention discloses a laser radar and a laser radar control method. The laser radar comprises a plurality of laser emitting plates for emitting emergent laser; and preset angles are formed between the plurality of laser emitting plates and a horizontal plane. Two or more than two laser emission units are arranged at each laser emitting plate. Therefore, the vertical resolution of the laser radar can be improved.

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] The laser radar emits laser light through a semiconductor laser transmitter and detects the echo light signal. The laser radar includes multiple laser transmitters, and each laser transmitter can measure a distance. The transmitting circuit device of the laser transmitter is relatively complex and the volume is large, so it cannot be...
