Abstract

Due to occlusion and other problems during point cloud scanning, the collected point clouds are often incomplete. Therefore, reconstructing a complete point cloud based on a partial point cloud with missing information is of great significance in practical work. In this paper, we propose a point cloud completion method (PointVQDM) based on the VQ-Diffusion model, which uses a discrete diffusion model to model in the latent space for shape reconstruction. Specifically, we obtain the corresponding vector combination based on the partial point cloud, and use the point cloud quantization network to decode it to obtain a complete point cloud. Experimental results on multiple datasets show that our PointVQDM outperforms the most advanced completion network. Moreover, thanks to our feature fusion method, we achieve diverse and high-quality generation results.
