Abstract

Embodiments of the present invention provide a face detection method and a terminal device, which relate to the field of communication technology and are used to solve the problem of low recognition accuracy of face recognition when existing terminals use a single camera for face recognition. The method is applied to a terminal device, and the terminal device includes a height-adjustable camera. The method includes: obtaining a first image collected by a camera at a first height position and a second image collected at a second height position; wherein, both the first image and the second image include a face image of a target face object; obtaining Disparity information between the first image and the second image; according to the disparity information, determine whether the target face object is a living body.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and terminal equipment for human face liveness detection. Background technique [0002] With the continuous development of terminal technologies, users use terminal devices (for example, smart phones, tablet computers, etc.) more and more frequently, and people's dependence on terminal devices also increases accordingly. Taking mobile phones as an example, due to the convenience brought by face unlocking, many mobile phones currently have the face unlocking function, so that the front camera of the mobile phone can be used for face recognition, and the current user is recognized as the owner of the mobile phone. automatically unlocks the phone. [0003] Because the cost of the depth camera is relatively high, the front camera of most mobile phones is still a single camera at present. However, when a single camera is used for face rec...
