Vehicle VIN code tampering detection method and device, equipment and storage medium

Abstract

The invention relates to a vehicle VIN code tampering detection method and device, equipment and a storage medium. The method comprises the steps of obtaining a VIN code image and a manufacturer identifier of a to-be-detected vehicle; determining a plurality of VIN code character images from the VIN code images, and respectively inputting the plurality of VIN code character images into a characterclassification model to obtain a classification result of each VIN code character image, wherein the classification result is used for representing the font type of the VIN character in the VIN character image; and obtaining a VIN code font standard corresponding to the manufacturer identifier, and determining a VIN code tampering detection result of the to-be-detected vehicle according to the classification result of each VIN code character image and the VIN code font standard. According to the method, the VIN code tampering detection process can be completed only by acquiring the VIN code image of the to-be-detected vehicle and the manufacturer identifier, so that the method is wider in application range and higher in efficiency in an actual scene; and the VIN code character images areclassified by adopting the character classification model, so that the detection speed is greatly increased, and the accuracy of a detection result is also improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, device and storage medium for tampering detection of vehicle VIN codes. Background technique [0002] With the continuous development of social economy and the continuous improvement of people's living standards, the number of urban motor vehicles has increased rapidly. Vehicle Identification Number (VIN), as the identification code of a motor vehicle, covers many important information such as the manufacturer, age, model, body type and code, engine code, assembly location, etc. of the vehicle. Whether it is to apply for a license plate, driving license, insurance or annual inspection of a motor vehicle, the VIN code information of the vehicle must be used. It is precisely because of the uniqueness and immutability of the vehicle VIN code that some criminals will tamper with the vehicle VIN code after stealing the vehicle to avoid some relevant insp...
