Problems solved by technology

[0003] During the installation and use of the laser radar, the laser radar needs to be commissioned and calibrated. However, in the existing design, the light spots on the receiving module of the laser radar are not easy to be monitored, especially for low-power laser radars, which can only be detected at night. Or only in a dark room environment can the LiDAR be commissioned and calibrated

Abstract

The embodiment of the invention provides a laser radar calibration device and calibration method. The laser radar calibration device comprises a collimator, a first detector, a reticle and a light source module. The first detector is used for detecting light spots on a receiving module of the laser radar. The laser radar is located on the first side of the collimator. The reticle and the light source module are located on the second side of the collimator, and the first side is opposite to the second side. The reticle is located on a light beam propagation path between the light source moduleand the collimator. The embodiment of the invention provides a laser radar calibration device and calibration method, so as to reduce the debugging and calibration difficulty of the laser radar and improve the debugging and calibration precision of the laser radar.

Description

technical field [0001] The invention relates to laser radar technology, in particular to a laser radar calibration device and calibration method. Background technique [0002] Lidar is a commonly used ranging sensor, which has the characteristics of long detection distance, high resolution and low environmental interference. It is widely used in intelligent robots, drones, unmanned driving, automatic driving and other fields. As the core sensor of distance perception in the above fields, lidar is indispensable. [0003] During the installation and use of the laser radar, the laser radar needs to be commissioned and calibrated. However, in the existing design, the light spots on the receiving module of the laser radar are not easy to be monitored, especially for low-power laser radars, which can only be detected at night. Or the lidar can only be commissioned and calibrated in a dark room environment. Contents of the invention [0004] Embodiments of the present invention...
