Title
(EN) Living body detection method and device and storage medium
(ZH) 活体检测方法、装置以及存储介质
Abstract
(EN)
The embodiment of the invention discloses a living body detection method and device and a computer readable storage medium. The method comprises the following steps: acquiring a first image acquired by a first image sensor of a binocular camera, and acquiring a second image acquired by a second image sensor of the binocular camera; performing binocular matching processing on the first image and the second image to obtain parallax information of the first image and the second image; and obtaining a living body detection result according to the parallax information. By adopting the embodiment ofthe invention, the living body detection precision can be improved.
