Problems solved by technology

[0004] If the range of the above-mentioned lidar meets the highest requirements during design, the cost will be higher and the volume may also be larger; if it is designed according to the minimum requirements for the range, it will not be able to meet the high range requirements, which will reduce the user experience and even reduce related applications, such as automobiles. safety performance; if designed according to the intermediate requirements, it may cause waste and fail to meet the demand
[0005] It can be seen that there is no laser radar in the prior art that can meet the requirements of high range and low range at the same time, and has a lower cost and a smaller submission

Abstract

The embodiment of the invention discloses a laser radar and a laser radar control method. The laser radar comprises two or more two groups of receiving terminal collimation units; and light transmission areas of the receiving terminal collimation units of different groups are different. In addition, according to another embodiment the invention, the invention also discloses a laser radar and a laser radar control method. The laser radar comprises two or more two groups of receiving terminal collimation units; and light transmission areas of the receiving terminal collimation units of different groups are same and the different groups of receiving terminal collimation units correspond to different groups of receiving units. Therefore, requirements of large range and small range of the laser radar can be met. Moreover, the cost is low and the size is small.

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] In the application of lidar, there may be different range requirements for different azimuth angles, such as lidar installed on cars. figure 1 Shown is a schematic diagram of the range requirements for a LiDAR mounted on an automobile. The obstacles directly in front of the car have the greatest impact on the driving of the car, so ...
