Vehicle laser radar automatic calibration device and calibration method

Abstract

The invention discloses a vehicle laser radar automatic calibration device and a calibration method. The device comprises a cuboid-shaped sealed house body and a PC. The PC is connected with laser radars mounted on a vehicle through utilization of data cables. The sealed house body comprises a frame body composed a left wall body, a right wall body, a rear wall body, a top plate and a ground. Adjacent surfaces of the frame body are mutually vertical. A front wall body of the sealed house body is assembled at a front end opening of the frame body in a slide rail movable mode. Inner end faces ofthe left wall body and the right wall body of the sealed house body are respectively equipped with an equidistant ladder. A plurality of equidistant and parallel marking lines are set on the ground of the sealed house body. According to the device and the method, automatic calibration can be realized, a calibration result is high in accuracy, a requirement for consistency can be satisfied, and manpower investment is greatly reduced. The device and the method are adaptable to a batch calibration requirement in a vehicle batch production process.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicle production, in particular to a radar calibration method and device on an unmanned vehicle. Background technique [0002] Intelligent driving or unmanned vehicles must be the development trend of vehicle intelligence. At present, there are news about intelligent vehicle testing and even landing operations in many provinces and cities across the country. Intelligent driving vehicles are already rapidly approaching my life. The current number of intelligent driving vehicles is relatively small, most of them are in the testing stage, generally there are several or dozens of such vehicles, most of the intelligent driving vehicles use one or more lidar as the main obstacle detection or map The construction basis of SLAM, but all these lidars will have inconsistent internal and external parameters due to their special technology, so they need to be calibrated separately before they can be used. ...

AI Technical Summary

Problems solved by technology

Due to the small quantity and mainly still in the testing stage, the timeliness requirements are not high, and it can basically meet the current application. However, once the batch or formal mass production is performed, manual calibration cannot meet the production needs, so it is urgently needed. An intelligent calibration method and device capable of meeting batch requirements and a relatively high degree of automation with low threshold
