Multi-dimensional stereo face reconstruction for psychological assistant diagnosis in medical meta-universe

Abstract

Virtual reality/augmented reality (VR/AR) technology is very important for meta-cosmic medicine. It is the technical link between the material world and the virtual world. The realization of face-to-face psychological diagnosis with three-dimensional holography is a difficult problem in meta-cosmic medicine. Because psychological diagnosis needs to observe rapidly changing microexpressions, it is difficult to capture them. At present, most of the research is based on two dimensions, which cannot meet the real-time reconstruction requirements of meta-universe medicine. To solve these problems, this paper introduces a 3D facial reconstruction algorithm composed of multiresolution feature fusion and attention mechanisms. It can be used for psychological assistant diagnosis of meta-cosmic medicine. First, face alignment and 3D coordinate construction of the feature point cloud are carried out through a 3D convolution coding network. After that, multiresolution cost convolution is used to extract and match the color, facial bones, and depth features of texture images. Finally, the transposed three-dimensional convolution is used to decode and output. To achieve the real-time reconstruction of psychotherapy, we designed a three-dimensional channel attention mechanism module for acceleration. This makes this method suitable for the construction of virtual doctors and virtual patients in the virtual platform of the medical universe of psychological medicine and can also complete the construction of the virtual teaching platform of the medical universe.
