Title:
VIVO DETECTION METHOD AND DEVICE BASED ON INFRARED VISIBLE BINOCULAR IMAGE
Document Type and Number:
WIPO Patent Application WO/2018/040307
Kind Code:
A1
Abstract:
The invention relates to a vivo detection method and device based on an infrared visible binocular image. The method comprises: S1, acquiring through an infrared camera infrared light imaging of an object to be identified, and acquiring through a visible light camera visible light imaging of the object to be identified; S2, if infrared light imaging contains no image, determining that the object to be identified is a non-living body, and otherwise, carrying out step S3; and S3, extracting characteristics of the eyes and face of the object to be identified in the visible light imaging and the infrared light imaging, and determining whether the object to be identified is a living body according to the extracted characteristics. Compared with the prior art, in the present invention, pre-identification is carried out by determining whether an infrared camera can acquire an image; in this way all video attacks, most pictures, hole attacks and 3d mask attacks can be prevented; and non-living body attacks are greatly attack prevented by means of characteristic comparison between visible light imaging and infrared light imaging.
