RELATIVE SPATIAL LOCALIZATION OF MOBILE DEVICES
To obtain a relative localization between a plurality of mobile devices, a first mobile device observes a second mobile device within a field of view of the first mobile device's camera at time t1, determines a first position of the first mobile device at t1, and receives from the second mobile...

| description | To obtain a relative localization between a plurality of mobile devices, a first mobile device observes a second mobile device within a field of view of the first mobile device's camera at time t1, determines a first position of the first mobile device at t1, and receives from the second mobile device a second position of the second mobile device at t1. The first mobile device determines information about the first mobile device's orientation with respect to the second mobile device at t1 based at least in part on the first position and the observation of the second mobile device. The first mobile device identifies two constraints that relate the mobile devices' coordinate systems based at least in part on the second position and the orientation information. The first mobile device's pose relative to the second mobile device may be calculated once at least six constraints are accumulated.
Pour obtenir une localisation relative entre une pluralité de dispositifs mobiles, un premier dispositif mobile observe un second dispositif mobile dans un champ de vision de la première caméra du dispositif mobile au moment t1, détermine une première position du premier dispositif mobile à t1, et reçoit du second dispositif mobile une seconde position du second dispositif mobile à t1. Le premier dispositif mobile détermine des informations concernant l'orientation du premier dispositif mobile par rapport au second dispositif mobile à t1 sur la base, au moins en partie, de la première position et de l'observation du second dispositif mobile. Le premier dispositif mobile identifie deux contraintes qui concernent les systèmes de coordonnées de dispositifs mobiles sur la base, au moins en partie, de la seconde position et des informations d'orientation. La première pose du dispositif mobile par rapport au second dispositif mobile peut être calculée une fois qu'au moins six contraintes sont accumulées. |
