Problems solved by technology
However, since the existing living body detection based on 3D reconstruction methods need to process images or videos with a large amount of data, the calculation steps of 3D reconstruction require a large amount of calculation.
Moreover, in the application of real-time liveness detection, whether more computing power can meet the real-time problem
[0007] At present, there is no recognized and mature living detection solution in the technical products on the market. The existing technologies are either difficult to resist malicious attacks, or require a large amount of calculation and take a long time

Embodiments of the present invention provide a living body detection method and device. The living body detection method includes: generating a pseudo depth map of the target according to at least two images of the target taken from different positions; and determining whether the target is a living body based on the pseudo depth map. This can not only effectively prevent the photos and videos taken in advance from attacking the system, but also has a small amount of calculation and short time consumption, so that it can meet the real-time requirements of the system.
Description
technical field [0001] The present invention relates to the field of image processing, and more particularly relates to a living body detection method and device. Background technique [0002] Currently, face-based authentication systems have been widely used. However, there are also some methods of maliciously deceiving face authentication, such as the following: [0003] For the most original face-based identity verification system (hereinafter referred to as face verification), malicious users may use the photo of the counterfeited person to attack (hereinafter referred to as "photo attack"). [0004] For "photo attack", face verification can effectively deal with "photo attack" by checking whether there are fine movements in a video of a face. Furthermore, face verification can require the verifier to perform specified actions to counter-attack. [0005] For the above anti-attack methods, malicious users may use devices such as tablet computers to play videos or anima...
