摘要：
In order to realize fast and accurate 3D face digitization at low cost, a high precision and robust automatic 3D face reconstruction method is proposed in this paper. Taking the left and right face point clouds and RGB image data collected by structured light camera as input, we first propose an adaptive sub-sampling global optimization ICP(iterative closest point) registration method to integrate the left and right point clouds, and then use a improved Poisson reconstruction method through normal vector optimization to reconstruct the surface of the point cloud after registration. The Poisson reconstruction method has good reconstruction effect and reconstruction accuracy for the face point cloud, which is a non-closed point cloud. Based on generated grid model, the RBG image was mapped to the mesh model, and finally a 3D face model with detailed texture is reconstructed. Extensive face reconstruction experiments demonstrate that the proposed method has the characteristics of high robustness and high precision, and can efficiently and accurately reconstruct the 3D face. © 2023 SinoMaps Press.
