Title
(EN) METHOD AND DEVICE FOR LIVENESS DETECTION, AND STORAGE MEDIUM
Abstract
(EN)

The embodiments disclose a method and device for liveness detection and a computer-readable storage medium. The method includes that: a first image collected by a first image sensor of a binocular camera is acquired, and a second image collected by a second image sensor of the binocular camera is acquired; binocular matching processing is performed on the first image and the second image to obtain parallax information of the first image and the second image; and a liveness detection result is obtained according to the parallax information.
