Description

technical field [0001] The invention relates to the field of experimental equipment, in particular, to a system and method for joint calibration and test of visual perception and laser radar. Background technique [0002] The development of ICVs will effectively improve traffic safety and achieve energy conservation and emission reduction, which is an integral part of achieving the dual carbon goals. The various sensors it carries rely on data and information fusion processing, which can effectively improve the environmental perception capability of intelligent networked vehicles and ensure the realization of automatic driving functions. Among them, the visual perception system mainly collects image and video data from the environment where the vehicle is located and extracts important visible information, which has certain anti-interference and low cost; 3D LiDAR mainly obtains reflected echoes by actively transmitting beams to extract the surrounding area of ​​the vehicle....

AI Technical Summary

Problems solved by technology

[0003] At present, the joint calibration of visual perception and lidar is mostly carried out on the test site with real vehicles. During the experiment, at least two people are required to conduct it outdoors. After the calibration, the data test is returned to the laboratory. Or when it is necessary to supplement the calibration data, the actual vehicle collection needs to be carried out again. There are many disadvantages such as inconvenient collection of joint calibration data, poor repeatability, and high potential safety hazards.
