Abstract: Embodiments disclosed facilitate resource utilization efficiencies in Mobile Stations (MS) during 3D reconstruction. In some embodiments, camera pose information for a first color image captured by a camera on an MS may be obtained and a determination may be made whether to extend or update a first 3-Dimensional (3D) model of an environment being modeled by the MS based, in part, on the first color image and associated camera pose information. The depth sensor, which provides depth information for images captured by the camera, may be disabled, when the first 3D model is not extended or updated.

Abstract: A mobile device uses vision and orientation sensor data jointly for six degree of freedom localization, e.g., in wide-area environments. An image or video stream is captured while receiving geographic orientation data and may be used to generate a panoramic cylindrical map of an environment. A bin of model features stored in a database is accessed based on the geographic orientation data. The model features are from a pre-generated reconstruction of the environment produced from extracted features from a plurality of images of the environment. The reconstruction is registered to a global orientation and the model features are stored in bins based on similar geographic orientations. Features from the panoramic cylindrical map are matched to model features in the bin to produce a set of corresponding features, which are used to determine a position and an orientation of the camera.
