Example Embodiment

[0036] The present invention will be further described below in conjunction with the drawings.

[0037] The invention is mainly based on the target detection module and the judgment module.

[0038] Such as figure 2 As shown, the target detection module is composed of a target detection unit and a character segmentation unit. First, the image is passed to the target detection unit, and the target detection model is applied to the image to obtain the image of the vehicle VIN code area. Then use the character segmentation model to segment the VIN code into individual characters. The target detection module first detects the vehicle VIN code area, and then performs character segmentation in the vehicle VIN code area. This step-by-step detection method can effectively avoid the impact of false detection due to the complex situation of the vehicle VIN code area, and improve the vehicle VIN code area The accuracy of positioning and character segmentation further improves the accuracy ...

Abstract

The invention discloses a vehicle VIN code recognition and detection method used for vehicle annual inspection, which comprises the following steps of obtaining a vehicle VIN code image to be detectedin vehicle annual inspection and a VIN code standard answer in a server; detecting an area where the VIN code is located, and judging whether a target exists or not; applying the VIN code recognitionresult of the character segmentation model to the image to be detected, and judging whether the VIN code recognition result is consistent with the VIN code standard answer content of the server. Themethod of the invention realizes the automatic identification and verification of the VIN code in the annual inspection of vehicles, replaces the existing manual verification mode, saves manpower, accelerates the verification speed, can effectively detect and identify the VIN code, and ensures the openness and fairness of the verification work.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence judgment for annual inspection of motor vehicles, in particular to a vehicle VIN code identification and detection method for annual inspection of vehicles. 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 the annual inspection of motor vehicles has also increased rapidly. In the traditional vehicle annual inspection, the vehicle VIN code identification and detection is mainly through manual detection, so there are often disadvantages such as high cost of manual verification, easy fatigue, and easy negligence, which affect the accuracy and efficiency of detection. Contents of the invention [0003] The purpose of the present invention is: to propose a vehicle VIN code identification and detection method for vehicle ...
