Abstract

The invention relates to a vehicle identification code detection method and device, and a computer device. The method comprises the steps of obtaining a to-be-detected image of a vehicle identification code and a reference character string of the vehicle identification code; detecting whether a vehicle identification code area image exists in the to-be-detected image or not through a target detection model, and if yes, extracting the vehicle identification code area image from the to-be-detected image; performing identification segmentation on the vehicle identification code area image througha character instance segmentation model, and generating a character string corresponding to the vehicle identification code area image according to an identification segmentation result of the vehicle identification code area image; comparing a character string corresponding to the vehicle identification code area image with a reference character string of the vehicle identification code; according to the comparison result, recording the first detection result of the vehicle identification code. The technical problem that the vehicle identification code cannot be accurately detected in the prior art is solved, and the accuracy of vehicle identification code detection is improved.

Description

Technical field [0001] This application relates to the field of vehicle detection, in particular to a detection method, device and computer equipment of a vehicle identification code. 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. The workload of annual inspection of motor vehicles has also increased rapidly. The detection and recognition of the vehicle identification code is one of the important items in the annual vehicle inspection. [0003] Among them, the Vehicle Identification Number (VIN) is a multi-character code as a unique identification code of a car, which contains information such as the manufacturer, year, model, body type and code, engine code, and assembly location of the vehicle. Under normal circumstances, the vehicle identification code consists of 17 characters, including letters and numbers, commonly known as ...
