Human body three-dimensional modeling data acquisition and reconstruction method and system based on single mobile phone

Abstract

The invention discloses a human body three-dimensional modeling data acquisition and reconstruction method and a human body three-dimensional modeling data acquisition and reconstruction system based on a single mobile phone. In the aspect of data acquisition, only a single smart phone is used, and an augmented reality technology is utilized to guide a user to acquire high-quality video data input for a reconstruction algorithm; therefore, a high-quality three-dimensional human body model can be stably obtained by a subsequent human body reconstruction algorithm. In the aspect of a reconstruction algorithm, a deformable implicit nerve radiation field is designed. The implicit space deformation field estimation model is used to solve the problem of tiny motion of a shot in the process of collecting data by a single mobile phone; the implicit distance field with symbols is used for representing the geometry of the human body, the expression ability is rich, and the reconstruction precision of the three-dimensional human body model is improved. By integrating data acquisition and reconstruction algorithms, reliable human body high-quality three-dimensional modeling data acquisition and reconstruction based on the single mobile phone are realized.

Description

technical field [0001] The invention belongs to the field of computer vision, and in particular relates to a method and a system for acquiring and reconstructing three-dimensional modeling data of a human body based on a single mobile phone. Background technique [0002] Human reconstruction is the basis for interactive and immersive applications such as virtual reality and augmented reality content creation, film and television creation, and virtual dressing. High-quality human reconstruction is a prerequisite for many application scenarios related to digital humans in virtual reality and augmented reality. The current human body acquisition and reconstruction schemes are mainly divided into two types: the professional multi-camera acquisition system is used to scan the human body to collect data. This acquisition system is very expensive and occupies a large area, which limits the large-scale use of high-precision human body reconstruction. commercialize. Another class o...

AI Technical Summary

Problems solved by technology

This type of method has weak processing ability for the sparse part of the human body texture, and cannot model the tiny movements of the human body during the acquisition process, which will easily lead to low integrity of the reconstruction results, and cannot meet the requirements of high-precision human body reconstruction at all.
