Embodiment Construction

[0054] 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.

[0055] The VIN image generation method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the collection terminal 102 communicates with the server 104 through the network. Specifically, the collection terminal 102 collects the VIN image on the vehicle frame to obtain the original VIN image, and then sends the original VIN image to the server 104 . After acquiring the original VIN image collected by the collection terminal 102, the server 104 determines multiple vertices in the VIN text area from the original VIN...

Abstract

The invention relates to the technical field of image recognition, in particular to a vehicle frame number image generation method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring an original image of a vehicle frame number; determining a plurality of vertexes of a vehicle frame number text area in the vehicle frame number original image, andobtaining original pixel coordinates of each vertex; acquiring camera coordinates under a camera coordinate system corresponding to each vertex from the point cloud data corresponding to the frame number original image based on the original pixel coordinates of each vertex; determining actual pixel coordinates of each vertex in the target vehicle frame number plane according to the camera coordinates of each vertex; establishing a perspective transformation matrix according to the original pixel coordinates and the actual pixel coordinates of each vertex; and according to the perspective transformation matrix, carrying out perspective transformation on the vehicle frame number original image to a target vehicle frame number plane to obtain a vehicle frame number image. By adopting the method, the intelligent level of vehicle frame number image generation can be improved.

Description

technical field [0001] The present application relates to the technical field of image recognition, 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 collected manually, and then the collected data is compared with the rubbing film to determine whether the VIN has been changed. [0004] However, through manual measurement and collection, the processing process is not intelligent enough. Contents of the invention [0005] Based on this, it is necessary to provide a VIN image generation method, device, computer equipment and storage medium capable of intelligently generating the VIN image for the above-mentioned technical ...
