Abstract

The present invention relates to hybrid photo navigation and mapping. Embodiments disclosed obtain a plurality of measurement sets from a plurality of sensors in conjunction with the capture of a sequence of exterior and interior images of a structure while traversing locations in and around the structure. Each measurement set may be associated with at least one image. An external structural envelope of the structure is determined from exterior images of the structure and the corresponding outdoor trajectory of a UE. The position and orientation of the structure and the structural envelope is determined in absolute coordinates. Further, an indoor map of the structure in absolute coordinates may be obtained based on interior images of the structure, a structural envelope in absolute coordinates, and measurements associated with the indoor trajectory of the UE during traversal of the indoor area to capture the interior images.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of U.S. Application No. 14 / 497,219, filed September 25, 2014, entitled "Hybrid Photo Navigation and Mapping," which claims benefit and priority of U.S. Provisional Application No. 61 / 883,921, entitled "Off-Target Tracking Using Feature Aiding in the Context of Inertial Navigation," filed on March 27 in It is incorporated herein by reference in its entirety. technical field [0003] The subject matter disclosed herein relates generally to terrestrial positioning systems, and in particular to systems and methods for hybrid photo navigation and mapping. Background technique [0004] It is often necessary to know the location of a terminal, such as a cellular telephone. For example, a Location Services (LCS) client may need to know the location of the terminal in case of an emergency services call or to provide a certain service to the user of the terminal, eg navigation ...
