Abstract
(EN)
A living body detection method and apparatus, and a computer readable storage medium, the method comprising: acquiring a first image collected by a first image sensor of a binocular camera, and acquiring a second image collected by a second image sensor of the binocular camera (S100); performing binocular matching on the first image and second image to obtain parallax information of the first image and second image (S200); according to the parallax information, obtaining a living body detection result (S300).

L'invention concerne un procédé et un appareil de détection de corps vivant et un support d'informations lisible par ordinateur. Le procédé consiste : à acquérir une première image collectée par un premier capteur d'image d'une caméra binoculaire et à acquérir une seconde image collectée par un second capteur d'image de la caméra binoculaire (S100) ; à effectuer une mise en correspondance binoculaire sur la première image et sur la seconde image pour obtenir des informations de parallaxe de la première image et de la seconde image (S200) ; en fonction des informations de parallaxe, à obtenir un résultat de détection de corps vivant (S300).
