Problems solved by technology
3D face recognition technology is limited by technical reasons such as equipment cost and processing speed, and its application is far from popular
[0003] Two-dimensional face recognition technology has a high recognition rate, but it is vulnerable to attacks of disguised faces, including: photos, videos, masks, 3D models, etc. Other means are needed to detect and prevent such attacks, such as through continuous video images To detect blinking and other actions, detect depth information through binocular vision, detect living bodies through infrared thermal imaging, detect texture information through infrared images, etc., but such technologies are not yet fully mature, which limits their applications

Embodiment Construction
[0058] In order to express the purposes, technical solutions and advantages of the embodiments of the present invention more clearly, the technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The embodiments are some of the embodiments of the present invention, not all of the embodiments.
[0059] A real face detection method based on infrared and visible light images, such as figure 1 shown, including the following steps:
[0060] Step 1. The infrared camera collects the infrared image of the face and saves it as a grayscale image; the visible light camera simultaneously collects the visible light image of the face and saves it as a color image.
[0061] Step 2, detect whether there is a face model in the infrared and visible light images at the same time; if not, determine that it is a non-real face, including:
[0062] Use the ...

The invention provides a real face detection method and device based on infrared and visible light images. Using synchronously acquired infrared and visible light images, comprehensively using face model, color, scale, texture, and depth information features, combined with face detection, color judgment, scale judgment, comprehensive texture judgment, and depth information judgment methods to better identify A variety of camouflaged face attacks have been detected to ensure the safe use of face recognition algorithms.
Description
technical field [0001] The invention relates to the technical field of digital image processing, in particular to a real face detection device and method based on infrared and visible light images. Background technique [0002] At present, two-dimensional face recognition technology is becoming more and more mature and has been widely used in many fields. 3D face recognition technology is limited by technical reasons such as equipment cost and processing speed, and its application is far from popular. [0003] Two-dimensional face recognition technology has a high recognition rate, but it is vulnerable to attacks of disguised faces, including: photos, videos, masks, 3D models, etc. Other means are needed to detect and prevent such attacks, such as through continuous video images To detect actions such as blinking, to detect depth information through binocular vision, to detect living bodies through infrared thermal imaging, to detect texture information through infrared ima...
