Abstract
The orientation of imagery relative to a compass bearing may be determined based on the position of the sun or other information relating to celestial bodies captured in the image.
Claims20
A system comprising:
- one or more processors;
- and
- memory storing instructions executable by the one or more processors to perform a method comprising:
- identifying a first position of a first feature in imagery based on a visual similarity of the first feature to a celestial object;
- identifying a second position of a second feature in the imagery based on a visual similarity of the second feature to an object associated with a known geographic location;
- determining, based on the first position relative to the second position, an azimuth angle, including determining an azimuth associated with a position 180 degrees from the second position of the second feature;
- associating a portion of the imagery with the determined azimuth angle;
- and
- determining, based at least partially on the azimuth angle and the azimuth, an orientation of the imagery.

A method, comprising:
- identifying, with one or more processors, a first position of a first feature in imagery based on a visual similarity of the first feature to a celestial object;
- identifying, with one or more processors, a second position of a second feature in the imagery based on a visual similarity of the second feature to an object associated with a known geographic location;
- determining, with one or more processors based on the first position relative to the second position, an azimuth angle, including determining an azimuth associated with a position 180 degrees from the second position of the second feature;
- associating, with one or more processors, a portion of the imagery with the determined azimuth angle;
- and
- determining, based at least partially on the azimuth angle and the azimuth an orientation of the imagery.

A non-transitory computer-readable medium storing instructions executable by one or more processors to perform a method, comprising:
- identifying a first position of a first feature in imagery based on a visual similarity of the first feature to a celestial object;
- identifying a second position of a second feature in the imagery based on a visual similarity of the second feature to an object associated with a known geographic location;
- determining, based on the first position relative to the second position, an azimuth angle, including determining an azimuth associated with a position 180 degrees from the second position of the second feature;
- associating a portion of the imagery with the determined azimuth angle;
- and
- determining, based at least partially on the azimuth angle and the azimuth an orientation of the imagery.
