VIN CODE IDENTIFICATION METHOD BASED ON IMAGE PROCESSING, DEVICE AND MEDIUM

摘要

A vin code identification method based on image processing, a device and a medium, applied to the technical field of image processing. The method comprises: obtaining vehicle environment information of a target vehicle (101); determining a target photographing parameter according to the vehicle environment information, and acquiring a vin code image of the target vehicle by using a photographing device according to the target photographing parameter (102); performing edge detection on the vin code image to obtain an edge image subjected to the edge detection (103); performing morphological closing operation on the edge image to obtain a closing operation image (104); performing morphological opening operation on the closing operation image to obtain an opening operation image (105); determining a minimum enclosing rectangle of a vin code region in the opening operation image, and determining the region determined by the minimum enclosing rectangle as the vin code region of the target vehicle (106); and identifying the vin code region of the target vehicle to identify the vin code (107). The method is conductive to improving the identification efficiency of the vin code of the vehicle image.
