【Abstract】In this paper,a monocular vision based vehicle distance measurement method based on license plate recognition system is proposed.Based on the methods of image transformation,model imaging and visual measurement,this paper analyzes the theory of LPR ranging and designs the application model of monocular visual ranging.The vehicle geometric feature information is used to locate the position image information of the vehicle ahead,and finally the vehicle license plate information is used to measure the distance of the vehicle ahead.

【Key words】LPR;license plate location;monocular vision;distance measurement
