Problems solved by technology

However, in the process of collecting and processing actual texture images, the obtained texture map is usually a summary of a series of taken texture photos, which contains a lot of redundant information and cannot be directly applied. In different ways, texture maps cannot be used universally, which brings great inconvenience to model processing

Embodiment Construction

[0047]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.

[0048] The 3D model texture mapping conversion 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. The terminal 102 can send the original texture map that needs to be texture mapped to the server 104 for processing, the server 104 uses the three-dimensional model texture map conversion method provided by this application to perform texture map processing, and feeds back the target texture map for texture map processing to the terminal 102...

Abstract

The present application provides a three-dimensional model texture map conversion method, device, computer equipment and storage medium, the method projects the vertices of the three-dimensional model facets into the initial target texture map, and calculates each facet in the initial target texture map The barycenter coordinates of the inner pixels, according to the existing original texture map mapping relationship, project the vertices of the 3D model face into the original texture map, and calculate the texture coordinates of the pixels in the original target texture map in the original texture map through the barycenter coordinates of the triangle , establish the mapping relationship from the initial target texture map to the original texture map, convert the original texture map into the actual target texture map, and realize the mutual conversion of any texture map.

Description

technical field [0001] The present application relates to the technical field of image data processing, in particular to a three-dimensional model texture map conversion method, device, computer equipment and storage medium. Background technique [0002] In the field of 3D digital imaging, in order to obtain a realistic 3D model, it is necessary to obtain a high-definition color image of the object, and generate a realistic 3D model through the mapping relationship between the 2D color image and the 3D model. Color images are usually obtained from photos taken by color cameras at different angles. In order to achieve accurate mapping, the conversion relationship between the color camera coordinate system and the 3D depth camera coordinate system must be accurately estimated, that is, obtained according to the internal and external parameters of the color camera. The mapping relationship between points on a three-dimensional object and pixels in a texture image. [0003] In ...
