Abstract:
Systems and methods for indoor localization in large-scale scenes, such as indoor environments are described. Systems and related methods for estimating the 3D camera pose of a depth camera by automatically aligning 3D depth images of a scene to a 3D CAD model of the scene are described.

Claim (Index 1):
A method of real-time depth camera pose estimation comprising:\n at a processor, receiving a sequence of depth map frames from a moving mobile depth camera, each depth map frame comprising a plurality of image elements, each image element being associated with a depth value related to a distance from the mobile depth camera to a surface in the scene captured by the mobile depth camera; tracking a 3D position and orientation of the mobile depth camera using the depth map frames and a 3D CAD model of the environment, the 3D position and orientation defining a pose of the mobile depth camera, the tracking involving storing the 3D position and orientation of the mobile depth camera in a storage device; computing, using an initial camera pose estimate, pairs of corresponding corner features between a current depth map frame and the 3D CAD model; updating the initial camera pose estimate by optimizing an error metric applied to the computed corresponding corner feature points; and outputting the updated camera pose estimate.
