AI Technical Summary

Problems solved by technology

Since the emitting circuit devices of laser emitters are usually complex and bulky, it is impossible to stack enough laser emitters in a small range, so that the distance between two adjacent laser emitters in the vertical direction is relatively large. This directly leads to the low vertical resolution of the multi-line lidar

Abstract

The invention discloses a laser emission assembly, a multi-line laser radar, a control method and a control system thereof and electronic equipment. The laser emission assembly is used for providing multiple beams of laser for the multi-line laser radar and comprises at least one laser emission plate and at least one group of laser emission units. Each set of laser emitting units is fixedly arranged on the corresponding laser emitting plate, and each laser emitting unit is used for emitting one beam of laser. The vertical distance between any two adjacent laser emitting units is smaller than the actual distance between the adjacent laser emitting units.

Description

Technical field [0001] The present invention relates to the technical field of laser radar, in particular to a laser emitting component and a multi-line laser radar, a control method, a control system and electronic equipment. Background technique [0002] Lidar is a radar system that emits a laser beam to detect the target's position, speed and other characteristic quantities. Its working principle is to first emit a laser beam to the target (ie, transmit a signal), and then reflect or scatter the received from the target. After comparing the laser echo (ie echo signal) with the transmitted signal, and after proper processing, relevant information about the target can be obtained, such as target distance, azimuth, height, speed, attitude, and even shape parameters. [0003] Currently, the lidars available on the market usually include mechanical multi-line lidars and solid-state lidars. Since the technology of solid-state lidar is not yet mature, multi-line lidar is still the mai...
