Model texture generation method based on generative adversarial network

Abstract

The invention discloses a model texture generation method based on a generative adversarial network. The method comprises the following steps: (1) for an input model, namely a three-dimensional modelof a texture-free map, acquiring sampling pictures of the model from a plurality of visual angles according to a given sampling rule; (2) carrying out edge detection processing on the sampling picture, and converting the sampling picture into a line frame picture; (3) establishing and training a generative adversarial network for generating color textures, taking the line frame diagram as the input of the network, and outputting a color texture diagram through the processing of the generative adversarial network; and (4) mapping the plurality of color texture images output by the network to the original model to realize texture coloring and obtain the three-dimensional model with the texture map. According to the method, the texture picture can be generated by building and training the deep convolution-based generative adversarial network, the manufacturing efficiency of the texture map is improved, the cost is saved, meanwhile, the environmental factors of texture generation are alsounified, and the consistency of final texture coloring is ensured.

Description

technical field [0001] The invention belongs to the technical field of computer graphics, and in particular relates to a method for generating model textures based on generative confrontation networks. Background technique [0002] Model texture plays an important role in the field of 3D model making. A 3D model is composed of many triangles, but these triangles themselves have no color value. If you want the surface of the 3D model to have a sense of color and unevenness, you must create a texture map and map it to the surface of the model in a specific way, so that the model has a more realistic visual effect. Therefore, the level of realism and detail of a model depends on the level of detail of its textures. [0003] At present, the main production method of model texture is that art engineers first carry out UV unwrapping on the model, set up the texture layout, and then use professional digital drawing software to manually draw the corresponding texture pattern. The...

However, the texture image obtained by this method will be affected by the actual lighting conditions. Unused sampling environments and sampling positions will lead to different lighting methods of the texture image, resulting in a large color difference between different textures when the final texture is colored. At the same time, texture boundaries will be different. There are phenomenon of overlapping colors and cracks
