Vehicle laser radar automatic calibration device and calibration method

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 grea
