Differential Tracking for Panoramic Images

A system, which comprises:

• a first 360 degree image capture device, configured to create a video while the first 360 degree image capture device moves along a path within a building at a first time;
• an image processing device, which comprises:
• a memory, which comprises:
• a 360 degree photo viewer application;
• and
• a processor, coupled to the memory, configured to:
• extract a plurality of first 360 degree photos from the video;
• derive one or more of locations and orientations within the building for each of the plurality of first 360 degree photos;
• obtain a plurality of second 360 degree photos at one or more positions in proximity to one or more points along the path at a second time later than the first time, the plurality of second 360 degree photos has one or more common locations and orientations within the building as the plurality of first 360 degree photos;
• display one or more first and second 360 degree photos in the 360 degree photo viewer application, the one or more second 360 degree photos corresponds to one or more first 360 degree photos taken from common locations within the building.

A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:

• creating, with a first 360 degree image capture device, a video while moving along a path within a building at a first time;
• extracting a plurality of first 360 degree photos from the video;
• deriving one or more of locations and orientations within the building for each of the plurality of first 360 degree photos;
• obtaining a plurality of second 360 degree photos at one or more positions in proximity to one or more points along the path at a second time later than the first time, the plurality of second 360 degree photos having one or more common locations and orientations within the building as the plurality of first 360 degree photos;
• and
• identifying differences between the first plurality of 360 degree photos and the second plurality of 360 degree photos.
