Data acquisition and reconstruction method and system for human body three-dimensional modeling based on single mobile phone

Abstract

A data acquisition and reconstruction method and a data acquisition and reconstruction system for human body three-dimensional modeling based on a single mobile phone. In the aspect of data acquisition, the present application only uses a single smart phone, and uses augmented reality technology to guide users to collect high-quality video data input for a reconstruction algorithm, so as to ensure that the subsequent human body reconstruction algorithm can stably obtain a high-quality three-dimensional human body model. In the aspect of a reconstruction algorithm, the present application designs a deformable implicit neural radiance field. The use of an implicit spatial deformation field estimation model solves the problem that the subject has small motion in the process of collecting data with a single mobile phone; the implicit signed distance field is used to represent human geometry, which has rich expressive ability and improves the accuracy of three-dimensional human model reconstruction.
