Embodiment 1

[0070] This embodiment provides a human face detection method, such as figure 1 As shown, the method includes: step 11 to step 14.

[0071] Step 11, acquire the color image and depth image of the target to be detected.

[0072] In some embodiments of the present application, two images of the target to be detected are collected simultaneously by an image acquisition device equipped with a natural light camera and a depth camera, or, while keeping the face information such as the face pose unchanged, by the The natural light camera and the depth camera successively collect two images of the target to be detected.

[0073] For example, a color image of the target to be detected is collected by a natural light camera, and a depth image of the target to be detected is collected by a depth camera. Wherein, the natural light camera and the depth camera are placed close to each other on the image acquisition device, so as to collect images of the target to be detected from similar ...

Embodiment 2

[0136] Correspondingly, this application also discloses a human face detection device, such as Image 6 As shown, the above-mentioned human face living body detection device includes:

[0137] An image acquisition module 610, configured to acquire a color image and a depth image of the target to be detected;

[0138] A normalization module 620, configured to determine the normalized face image corresponding to the color image and the depth image respectively;

[0139] The first feature determination module 630 is configured to determine the correlation features of the color image and the depth image by performing correlation analysis on the normalized face image of the color image and the normalized face image corresponding to the depth image; and,

[0140] The second feature determination module 640 is configured to determine the depth consistency feature of the depth image by performing depth consistency analysis on the normalized face image corresponding to the depth image...

Abstract

The invention provides a human face living body detection method, belongs to the technical field of human face identification, and solves the problems of low human face living body detection efficiency and accuracy in the prior art. The method comprises the steps of obtaining a color image and a depth image of a to-be-detected target; determining normalized human face images corresponding to the color image and the depth image; by performing correlation analysis on the normalized human face images corresponding to the color image and the depth image, determining a correlation feature of the color image and the depth image; by performing depth consistency analysis on the normalized human face image corresponding to the depth image, determining a depth consistency feature of the depth image;and according to the correlation feature and the depth consistency feature, performing human body living body detection on the to-be-detected target. According to the method, the human body living body detection is performed in combination with color information and space information in the images of the to-be-detected target, so that the living body detection accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of face recognition, and in particular to a face liveness detection method and device. Background technique [0002] Face recognition technology is more and more widely used in biometric identification devices such as attendance machines, access control systems, and electronic payment systems, which greatly facilitates people's daily life. [0003] However, with the widespread application of face recognition technology, the importance of face attack detection has become increasingly prominent. Commonly used face attack methods include: face recognition by using forged face images, face videos or face molds to pretend to be real faces. [0004] Usually, face attacks can be identified by performing face liveness detection on images to be recognized. In the prior art, commonly used face detection methods include face detection based on motion information, face detection based on texture feature anal...
