Abstract
(EN)
An image acquisition method, an image acquisition device (400), a structured light assembly (20), and an electronic device (1000). The image acquisition method comprises: controlling a structured light camera (22) to receive structured light that is diffracted, during emission, by a display area (11) of a display screen (10) and then reflected by a target object, and during being incident, diffracted by the display area (11), to obtain a scattered speckle image; acquiring a depth image according to a first measurement speckle, a second measurement speckle, and a third measurement speckle in the speckle image and a reference speckle in a reference image.
(FR)
L'invention concerne un procédé d'acquisition d'images, un dispositif (400) d'acquisition d'images, un ensemble (20) à lumière structurée, et un dispositif électronique (1000). Le procédé d'acquisition d'images comporte les étapes consistant à: commander une caméra (22) à lumière structurée pour recevoir une lumière structurée qui est diffractée, pendant l'émission, par une zone (11) d'affichage d'un écran (10) d'affichage, puis réfléchie par un objet cible et qui, pendant qu'elle est incidente, est diffractée par la zone d'affichage (11), pour obtenir une image tachetée dispersée; acquérir une image de profondeur d'après une première tache de mesure, une deuxième tache de mesure et une troisième tache de mesure dans l'image tachetée et une tache de référence dans une image de référence.
