Embodiment Construction

[0053] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] refer to figure 1 , which shows a flow chart of Embodiment 1 of a three-dimensional human face living body recognition method of the present invention, the method includes:

[0055] Step 101, collecting a three-dimensional face image.

[0056]Usually collect three-dimensional face images with a three-dimensional data acquisition module, and the three-dimensional data acquisition module may include: a 3D camera for collecting three-dimensional face data; a data processing module for processing the three-dimensional face data to generate a three-dimensional face image. Different from a two-dimensional face image, a three-dimensional face image contains depth information of a face, and the depth information refers to distanc...

Abstract

The invention provides a three-dimensional face living body recognition method and device and relates to the technical field of face recognition and image processing. The method comprises the following steps: collecting a three-dimensional face image; carrying out normalization processing on the three-dimensional face image; calculating depth histogram information or related coefficients of the three-dimensional face image according to the depth information of various points of the normalized three-dimensional face image; and judging whether the three-dimensional face image is from a living body or not according to the depth histogram information or the related coefficients. Living body recognition is carried out according to the depth histogram information or the related coefficients, so that the recognition result is high in accuracy; and the three-dimensional face living body recognition method and device have robustness and stability.

Description

technical field [0001] The invention relates to the technical field of face recognition and image processing, in particular to a three-dimensional human face living body recognition method and a three-dimensional human face living body recognition device. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called portrait recognition and facial recognition. The use of face recognition technology can effectively enhance security and privacy, but there is a problem in reality, that is, using false information such as printed photos, photos or videos in mobile phones or pads can break through the security defense line of the face recognition sys...
