Abstract

The present disclosure relates to a living body detection method and device. The method includes: acquiring the depth information of the target object sensed by the first sensor and the target image sensed by the second sensor; performing key point detection on the target image to obtain key point information of the target object; based on the The depth information of the target object and the key point information of the target object are obtained to obtain the liveness detection result of the target object. The present disclosure performs living body detection by combining the depth information of the target object and the target image, so that the depth information of the target object and the key point information of the target object in the target image can be used for living body detection, thereby improving the accuracy of living body detection.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, in particular to a living body detection method and device. Background technique [0002] At present, face recognition technology has been widely used in scenarios such as face unlocking, face payment, unmanned supermarkets, and video surveillance. However, face recognition technology has the risk of being easily attacked by prosthetic faces in the form of physical photos of faces, electronic photos of faces, or videos containing faces. Therefore, liveness detection is an essential part of face recognition. Contents of the invention [0003] In view of this, the present disclosure proposes a living body detection method and device. [0004] According to an aspect of the present disclosure, a living body detection method is provided, comprising: [0005] acquiring the depth information of the target object sensed by the first sensor and the target image sensed by the second s...
