This invention discloses a point cloud completion method and system for the medical field, relating to the field of 3D medical image processing technology. In this invention, the encoder dynamically constructs local neighborhoods and extracts multi-scale geometric features through three-level graph-edge convolution and farthest-point downsampling. These features are then combined with multi-scale stitching and global pooling to accurately capture local anatomical details such as high curvature and complex topology in medical point clouds, avoiding the loss of local features by general encoders. The decoder employs a four-stage point cloud deconvolution module, progressively upsampling through a combination of point splitting, displacement prediction, and feature interaction. Combined with self-attention or Mamba architecture for modeling long-range dependencies, this ensures that the point cloud density gradually increases while maintaining structural continuity. This invention enables the network to learn both global anatomical morphology and focus on local fine structures, resulting in a completed point cloud that is not only structurally rich and free of holes and distortions, but also strictly conforms to medical anatomical constraints such as the skull and cheekbone.
