Hybrid photo navigation and mapping
First Claim
1. A method on a user equipment (UE) comprising:
- capturing a plurality of images of an interior of a structure when traversing a plurality of locations within the structure;
capturing a plurality of measurement sets, wherein each measurement set corresponds to at least one image in the plurality of images, and each measurement set comprises at least one of Inertial Measurement Unit (IMU) measurements or available wireless measurements;
estimating a trajectory of the UE based, in part, on the plurality of images and the corresponding plurality of measurement sets;
sending the estimated trajectory, the plurality of images and corresponding measurement sets to a server wirelessly coupled to the UE; and
receiving, based on the estimated trajectory, the plurality of images and corresponding plurality of measurement sets, an indoor map of the structure from the server, wherein the indoor map is registered to absolute coordinates and comprises information pertaining to a corrected trajectory of the UE.

Abstract
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.
