Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040]Unlike Billy et al., who normalize face images in different poses to the frontal standard pose, another approach is to rotate the standard frontal pose face images in the registration library to many different poses, and the face images to be recognized Compare with the face images in these different poses respectively. The results show that, instead of transforming the face data to be recognized from different poses to frontal poses for similarity comparison...

Abstract

The invention provides a three-dimensional image face recognition method and a three-dimensional image face recognition system. The three-dimensional image face recognition method specifically comprises the steps that a standard reference face model and a registration library of a face database under a front posture are established in advance; aligning the depth data with a depth image of a standard reference face model, and obtaining attitude parameters; realizing texture image alignment according to the attitude parameters; respectively carrying out feature extraction on the aligned depth image and texture image, carrying out calculation through a depth classifier to obtain depth similarity Sdepth, and selecting a corresponding texture classifier according to the deflection attitude angle to calculate texture similarity Stexture; and utilizing the finally aligned face image and the obtained similarity data to carry out final face recognition by utilizing RGB-D. The 3D texture matching is carried out by using a pre-stored standard 3D face library to predict shielded facial textures, so that the recognition performance under the conditions of large posture change and serious shielding can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a method and system for face recognition of a three-dimensional image. Background technique [0002] Today, face recognition technology has become a widely used intelligent biometric technology, which is widely used in various fields. Compared with two-dimensional face recognition, three-dimensional face recognition has a higher recognition rate and has attracted more and more attention. Most of the 3D face images are not frontal images, and there are problems of different poses. [0003] If you want to improve the accuracy of face recognition in different poses, you need to pre-store the image data of each person's different poses in the database. Based on the size of the database and the feasibility of actual calculation, it is a question of how many face images to project in advance. For example, if the projection angle interval is defined as 5 degrees, then in the ...
