Embodiment Construction

[0022] The academic world is paying more and more attention to the research of 3D face recognition technology. It can be said that the current 3D face recognition has become a research hotspot in the field of international face recognition. The main technical process of the three-dimensional face detection and recognition technology of the present invention is:

[0023] (1) 3D face detection, data acquisition, collected through 3D imaging technologies such as structured light or stereo vision;

[0024] (2) 3D face cutting, data preprocessing, including face detection, cutting, denoising, etc.;

[0025] (3) 3D face pose correction, data feature extraction;

[0026] (4) 3D face recognition, build a suitable classifier to discriminate face data.

[0027] The acquisition of 3D face data is the first step of a complete face recognition system, and it is also a key step of the whole recognition system. The completeness and quality of the obtained 3D data directly affect t...

Abstract

The invention discloses a three-dimensional face detection and identification technology. The major technical process comprises: first of all, carrying out three-dimensional face detection to obtain data which is obtained by use of a 3D imaging technology such as structured light or stereo visual sense and the like, secondly, carrying out three-dimensional face cutting and data preprocessing which comprise face detection, cutting, denoising and the like, then, carrying out posture correction on a three-dimensional face and performing characteristic extraction on the data, and finally, carrying out three-dimensional face identification to construct a proper classifier for determining the face data. 3D face identification research can be traced back to as early as early 90s of last century, due to restrictions of various factors, such as computing level restrictions of computers, immature 3D acquisition devices and the like, no great breakthroughs are made in correlation research. During the last decade, along with rapid development of a computer technology and the 3D imaging technology and development bottlenecks of a 2D face identification technology as well, the academic society gives more attention to the research on a 3D face identification technology.

Description

technical field [0001] The invention relates to the field of biological identification, in particular to a three-dimensional face detection and identification technology. technical background [0002] In modern society, people pay more and more attention to social public security and personal information security. Personal identity authentication requirements are everywhere, ranging from personal attendance systems, access control systems, payment systems, etc., to national security. airports, information security, finance, military and other fields. The traditional identification technology characterized by passwords, cards, certificates, etc. is increasingly difficult to meet the requirements. Passwords are easily stolen, and cards and certificates are easily counterfeited. Especially in today's environment of potential terrorist threats in some parts of the international community, the crime of fake identity is a common tactic of terrorist extremists. In order to ensur...
