Abstract

The invention provides a living body detection method and device, a chip and a computer readable storage medium. The living body detection method comprises the following steps: acquiring a visible light image and an infrared light image; performing face detection on the visible light image; when a visible light face image of which the quality meets a preset condition is detected, combining the visible light image and the infrared light image to obtain a combined image; performing living body detection on the human face in the combined image through a living body classification model based on a neural network; and performing living body detection on the face in the combined image through an anti-attack model group. According to the living body detection method provided by the embodiment of the invention, various attack behaviors are effectively resisted through various infrared and visible image data sources and various living body detection models, and the user experience can be improved while the safety of living body judgment is improved.

Description

technical field [0001] The invention relates to the field of face recognition, in particular to a living body detection device method, device, chip and computer-readable storage medium. Background technique [0002] Face recognition technology has high development prospects and economic benefits in the fields of public security investigation, access control system, target tracking and other civilian security control systems. However, various attacks are often encountered in the process of face recognition, for example, using photos, masks or even videos as means of attack. Therefore, we need to analyze whether the collected images are live face images for liveness detection. [0003] In the prior art, there are different methods for living body detection. For example, 3D structured light can be used for living body detection, but structured light is expensive and cannot be widely used. Other liveness detection is performed through interaction with the user, such as requir...
