Abstract

Se describe la localización de cámaras móviles utilizando mapas de profundidad para robótica, juegos absorbentes, realidad aumentada y otras aplicaciones. En una materialización se rastrea una cámara móvil de profundidad en un entorno, al mismo tiempo que se forma un modelo 3D del entorno utilizando los datos de profundidad detectados. En una materialización, cuando falla el seguimiento de cámara, el asunto se detecta y la cámara se relocaliza, ya sea utilizando fotogramas clave previamente recopilados o de otras formas. En una materialización, se detectan finalizaciones de ciclos en los cuales la cámara móvil retoma una ubicación, comparando características de un mapa de profundidad actual con el modelo 3D en tiempo real. En algunas materializaciones las finalizaciones de ciclos detectadas se utilizan para mejorar la consistencia y precisión del modelo 3D del entorno.
