Abstract

Disclosed in the present application are an image processing method and a related apparatus. The image processing method comprises: when it is required to perform three-dimensional reconstruction on a preset object, acquiring a two-dimensional image of a preset object; performing feature extraction on the two-dimensional image to obtain first image features of the two-dimensional image; by means of a point cloud feature conversion network, performing feature conversion on the first image features to obtain corresponding first point cloud features; and then inputting the first point cloud features into a model creation module, so that the model creation module outputs a three-dimensional model of the preset object on the basis of the first point cloud features. The first point cloud features can reflect complete three-dimensional space information of the preset object and the three-dimensional geometric shape of the surface of the preset object, and provide richer content for three-dimensional reconstruction. Even if some parts are invisible, information of invisible areas can still be accurately inferred and supplemented by means of first point cloud features of other angles, thus improving the reconstruction effect of three-dimensional models, and avoiding the problems of serious geometric deformation, singularity or geometric blurring.
