Embodiment Construction
[0049] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0050] The VIN image generation method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. Specifically, the terminal 102 collects the original image of the VIN, and sends the collected original image of the VIN to the server 104 . After the server 104 acquires the original VIN image, it can identify the reference mark and the VIN area of the original image of the VIN, and obtain the identification positioning frame of each reference mark in...

The invention relates to the technical field of computers, in particular to a vehicle frame number image generation method and device, computer equipment and a storage medium. The method comprises thesteps: acquiring a vehicle frame number original image, wherein the vehicle frame number original image comprises a plurality of reference identifier groups, and each reference identifier group comprises a plurality of reference identifiers; performing reference identification and vehicle frame number area identification on the vehicle frame number original image to respectively obtain an identification positioning frame of each reference identification in each reference identification group and a vehicle frame number positioning frame of the vehicle frame number area; obtaining an actual position relationship of each reference identifier, obtaining a reference coordinate corresponding to the actual position relationship, and obtaining a target perspective transformation matrix corresponding to a plurality of reference identifier groups based on the reference coordinate and each identifier positioning frame; according to the vehicle frame number positioning frame of the vehicle framenumber area, performing perspective transformation processing on the vehicle frame number area through the target perspective transformation matrix to obtain a vehicle frame number image. By adoptingthe method, the vehicle frame number image generation accuracy can be improved.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for generating a VIN image. Background technique [0002] The VIN is the unique identification to identify the vehicle. In the annual vehicle inspection, it is very important to judge whether the frame number has been tampered with by comparing the frame number with the rubbing film. [0003] In the traditional way, the VIN size is manually collected, and then the collected data is compared with the rubbing film to determine whether the VIN has been changed. [0004] However, the manual measurement and collection is not intelligent enough to deal with, and the accuracy of the determination result of the VIN is low due to errors caused by manual measurement. Contents of the invention [0005] Based on this, it is necessary to provide a VIN image generation method, device, computer equipment and storage medium ...
