Three-dimensional human body model fitting method based on two-dimensional contour interaction and semantic segmentation

This invention discloses a method for fitting a 3D human body model based on 2D contour interaction and semantic segmentation. The method first parses a user-drawn 2D stick figure skeleton using a JPN module and drives an SMSLX model to generate an initial 3D human body. Then, the initial model contour is rendered from multiple fixed perspectives, generating corresponding bounding voxel spaces and point cloud projections. A prior network combining UDF and positional information is introduced to guide the training of the multi-view semantic segmentation network module UPS, achieving accurate segmentation of each part of the contour image. Based on the segmentation results and voxel point cloud projections, surface constraint point clouds for each body part are calculated. Finally, using the constraint point clouds as targets, the SMSLX model parameters are optimized for each part using a CFM module, ultimately generating a 3D human body shape that matches the user's editing intent. This invention allows users to indirectly adjust complex 3D models through intuitive 2D contour editing, significantly improving interaction efficiency and avoiding direct manipulation of complex 3D data.
