Title:
HUMAN FACE DATA PROCESSING METHOD AND DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/088867
Kind Code:
A1
Abstract:
Disclosed is a human face data processing method, comprising: acquiring a picture of a human face by means of a scanning apparatus, obtaining point cloud information by means of a structured light stripe, and then obtaining a three-dimensional model of the human face (S110); and mapping the three-dimensional model onto a circular plane in an area-preserving manner, so as to form a two-dimensional facial image (S130). Three-dimensional data is converted into two-dimensional data, thereby facilitating data storage. In addition, the three-dimensional data uses the area-preserving manner, such that the restoration quality is better when the two-dimensional data is restored to the three-dimensional data, thereby facilitating the re-utilization of a three-dimensional image.
