Abstract

The present disclosure provides a living body detection method, device, and storage medium, wherein the method includes: acquiring images including an object to be detected through a binocular camera, respectively, to obtain a first image and a second image; and determining the first image and the second image. key point information on the second image; according to the key point information on the first image and the second image, determine the depth information corresponding to each of the multiple key points included in the object to be detected; A detection result indicating whether the object to be detected belongs to a living body is determined according to the depth information corresponding to each of the multiple key points. The present disclosure can improve the accuracy of living body detection by the binocular camera and reduce the misjudgment rate without increasing the cost.

Description

technical field [0001] The present disclosure relates to the field of computer vision, and in particular, to a method and device for living body detection, and a storage medium. Background technique [0002] Currently, monocular cameras, binocular cameras, and depth cameras can be used for liveness detection. Among them, the single-shot living device is simple and low-cost, and the misjudgment rate is one thousandth. The misjudgment rate corresponding to the binocular camera can reach 1 in 10,000. The false positive rate corresponding to the depth camera can reach one in a million, but the cost of the depth camera is relatively high. SUMMARY OF THE INVENTION [0003] The present disclosure provides a living body detection method and device, and a storage medium. [0004] According to a first aspect of the embodiments of the present disclosure, there is provided a method for detecting a living body, the method comprising: acquiring images including an object to be detect...
