Title (EN) SENSING APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE DÉTECTION
Abstract:
(EN) A method comprises positioning a display screen of a mobile device and a surface of interest such that the display screen of the mobile device faces the surface of interest; emitting light by the display screen, wherein at least part of the emitted light is reflected by the surface of interest; receiving, by a camera of the mobile device, at least part of the light emitted by the display screen and reflected from the surface of interest thereby to generate at least one image; and processing the at least one image to determine at least one property of the surface of interest.
(FR) L’invention concerne un procédé qui comprend le positionnement d'un écran d'affichage d'un dispositif mobile et d'une surface d'intérêt de telle sorte que l'écran d'affichage du dispositif mobile fait face à la surface d'intérêt ; l'émission de lumière par l'écran d'affichage, au moins une partie de la lumière émise étant réfléchie par la surface d'intérêt ; la réception, par une caméra du dispositif mobile, d'au moins une partie de la lumière émise par l'écran d'affichage et réfléchie par la surface d'intérêt pour ainsi générer au moins une image ; et le traitement de la ou des images pour déterminer au moins une propriété de la surface d'intérêt.
