Title (EN) DETECTION OF WHETHER MOBILE COMPUTING DEVICE IS POINTING TO VISUAL CODE
(FR) DÉTECTION DE LA DIRECTION D'UN DISPOSITIF INFORMATIQUE MOBILE VERS UN CODE VISUEL
Abstract:
(EN) First and second confidence values are determined. The first confidence value corresponds to a likelihood that, from a position and an orientation of a mobile computing device, the mobile computing device is pointing to a visual code. The second confidence value corresponds to a likelihood that, from an image captured by the mobile computing device, the mobile computing device is pointing to the visual code. Whether the mobile computing device is pointing to the visual code is determined based on the first confidence value and the second confidence value.
(FR) Des première et seconde valeurs de confiance sont déterminées. La première valeur de confiance correspond à une probabilité que, à partir d'une position et d'une orientation d'un dispositif informatique mobile, le dispositif informatique mobile est dirigé vers un code visuel. La seconde valeur de confiance correspond à une probabilité que, à partir d'une image capturée par le dispositif informatique mobile, le dispositif informatique mobile est dirigé vers le code visuel. Il est déterminé si le dispositif informatique mobile est dirigé vers le code visuel, sur la base de la première valeur de confiance et de la seconde valeur de confiance.
