Problems solved by technology

[0004] General researchers must use expensive professional equipment for 3D face reconstruction, because most face reconstruction methods rely on pre-calibrated cameras or use landmark trackers to estimate the camera pose relative to geometric objects, various The work is concentrated on the use of photometric stereo or multi-view stereo technology for facial structure reconstruction. This requirement is too poor in operability and high in cost, which is not conducive to the development and research of technology.

Abstract

The invention provides a face reconstruction method and related equipment. The face reconstruction method comprises the steps of obtaining a first number of face images of a face reconstruction targetobject; obtaining a second number of two-dimensional graphs corresponding to the first number of face images through a three-dimensional origin space calculation model according to the first number of face images; obtaining a three-dimensional point graph according to the second number of two-dimensional graphs; and reconstructing a three-dimensional face according to the three-dimensional pointgraph. According to the face reconstruction method and the related equipment provided by the embodiment of the invention, the problems of poor operability and high cost of an existing three-dimensional reconstruction method can be solved to a certain extent.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a face reconstruction method and related equipment. Background technique [0002] One of the more concerned directions in three-dimensional (3D) face research is 3D face reconstruction, that is, to reconstruct a 3D model of a face from one or more face images. It has many application scenarios and can be used in virtual character scenes, such as movies, animation, social networking, etc. Accurate 3D rendering of faces may also be useful when building customized surgical masks or respirators, and the commercial space is very extensive. [0003] The 3D reconstruction of the face has been an open problem in computer vision and computer graphics because people are very sensitive to the appearance of the face, and slight anomalies in the reconstruction process can make the final result look very different from reality, high level of detail This is a difficult poi...
