Abstract

The invention relates to a living body detection method, a device, a system, electronic equipment and a storage medium, which can improve the accuracy of living body detection. The method comprises the following steps: acquiring a first image and a first depth map corresponding to the first image; updating the first depth map based on the first image to obtain a second depth map; and determining aliving body detection result of the target object in the first image based on the first image and the second depth map.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular to a living body detection method, device and system, electronic equipment and a storage medium. Background technique [0002] At present, face recognition technology has been widely used in scenarios such as face unlocking, face payment, unmanned supermarkets, and surveillance security. 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. How to improve the accuracy of living body detection is a research hotspot in this field. Contents of the invention [0003] The present disclosure proposes a living body detection technical solution. [0004] According to an aspect of the present disclosure, a living body detection method is provided, including: a...
