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 9):
The method of  claim 1 , wherein computing pairs of corresponding corner features using the initial camera pose estimate comprises:\n receiving the initial camera pose estimate, a current depth map, and 3D CAD model corners; identifying model corners predicted to be in a field of view of the mobile depth camera; projecting the current depth map onto the 3D CAD model using the initial camera pose estimate to generate a projected depth map; for each identified model corner,\n searching a surrounding area for corresponding corner candidates in the projected depth map; \n selecting candidate corresponding corners according to a distance metric; \n generating four point corner features from the model and the depth map; and \n outputting the four point corner features.
