The invention discloses a multi-sensor offline composite calibration system and method.The multi-sensor offline composite calibration system comprises a target, a radar calibration plate, a positioner, a straightening device and a controller, and the target is arranged in a calibration site and used for allowing a to-be-calibrated camera to shoot images; the radar calibration plate is arranged in a calibration site and is used for detecting the distance by a radar to be calibrated; the positioner is used for guiding the vehicle to enter a calibration position when the vehicle is in a calibration site; the straightening device is connected with the positioner and is used for controlling the vehicle driving into the calibration position to be straightened; and the controller is connected with the straightening device, and is used for acquiring calibration site data, images of targets around the vehicle shot by the to-be-calibrated camera and the detection distance of the to-be-calibrated radar detection radar calibration plate, and judging whether camera and radar calibration is reasonable or not. According to the invention, composite calibration of a plurality of sensors can be carried out, and the calibration accuracy is high.
