The invention provides a vehicle position information detection system and method based on a #-shaped calibration line. The precision of a vehicle position detection result is improved. The system comprises a camera mounting bracket, an area-array camera and a laser range finder which are arranged on the camera mounting bracket, a photographing switch connected with the area-array camera, a #-shaped calibration line fixed in a parking space, an information processing server and a display; the area-array camera is used for collecting a to-be-detected vehicle image containing the #-shaped calibration line according to a photographing signal sent by the photographing switch after a to-be-detected vehicle is parked in a parking space, and uploading the collected image to the information processing server. The laser range finder is used for measuring the height of the to-be-detected vehicle and uploading the measured height information to the information processing server. The information processing server is used for processing the received image and height information to obtain the position information of the to-be-detected vehicle. The invention relates to the field of automatic control of unmanned overhead travelling cranes.
