1. A method for reconstructing a three-dimensional model, performed by a computer device, the method comprising:
obtaining an image feature coefficient of an input image;
obtaining, based on the image feature coefficient, a texture of the input image, and a shape of the input image, a global feature map and an initial local feature map, the global feature map comprising a global texture feature map and a global shape feature map;
performing edge smoothing on the initial local feature map to obtain a target local feature map, the target local feature map comprising a local texture feature map and a local shape feature map;
modifying the target local feature map to be of a same size as the global feature map,
splicing the global feature map and the target local feature map based on the texture to obtain a target texture image, wherein the splicing comprises fusing pixels located at a same position in the global texture feature map and the local texture feature map;
splicing the global feature map and the target local feature map based on the shape to obtain a target shape image, wherein the splicing comprises fusing pixels located at a same position in the global shape feature map and the local shape map; and
performing three-dimensional model reconstruction based on the target texture image and the target shape image to obtain a target three-dimensional model.
