Abstract

The invention provides a face 3D characteristic identity information database building method and equipment; the method comprises the following steps: collecting a personal face RGBD atlas, wherein the personal identity information is known; using the face RGBD atlas to obtain face 3D characteristic information of the person; tagging the personal identity information to the corresponding personal face 3D characteristic information so as to obtain personal information, and storing the personal information so as to form a face 3D characteristic identity information database. The equipment comprises a first acquisition module, a first information obtaining module and an information database module; the method and equipment can improve face identification accuracy, and can identify faces without being affected by non-geometry appearance changes like face attitude, expression, illumination and face cosmetics, and face fat / thin changing conditions.

Description

technical field [0001] The invention relates to the field of methods for establishing a face 3D feature identity information database, in particular to a method and equipment for establishing a human face 3D feature identity information database. Background technique [0002] The issue of information security has attracted widespread attention from all walks of life. One of the main ways to ensure information security is to accurately identify the identity of the information user, and further judge whether the authority of the user to obtain information is legal through the identification results, so as to ensure that the information is not leaked and the legitimate rights and interests of the user are protected. Therefore, reliable identification is very important and necessary. [0003] Face recognition is a biometric technology for identification based on human facial feature information. As a safer and more convenient personal identification technology, face recognition...
