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.
Claims13
A system comprising:
- one or more processors;
- and
- memory storing instructions, the instructions executable by the one or more processors, wherein the instructions comprise:
- identifying a position of a feature in imagery based on a visual similarity of the feature to a shadow;
- determining, by one or more computing devices, an azimuth value based on the position of the feature in the imagery;
- calculating a compass bearing for a portion of the imagery based on the determined azimuth value;
- and
- associating the portion of the imagery with the calculated compass bearing, the associating comprising determining a sun azimuth associated with a position approximately 180° from the position of the feature.
5 more elements
A computer-implemented method comprising:
- identifying, by one or more computing devices, a position of a feature in imagery based on a visual similarity of the feature to a shadow;
- determining, by one or more computing devices, an azimuth value based on the position of the feature in the imagery;
- calculating, by the one or more computing devices, a compass bearing for a portion of the imagery based on the determined azimuth value;
- and
- associating, by the one or more computing devices, the portion of the imagery with the calculated compass bearing, the associating comprising determining a sun azimuth associated with a position approximately 180° from the position of the feature.
2 more elements
A non-transitory computer-readable medium storing instructions executable by one or more processors to perform a method, comprising:
- identifying a position of a feature in imagery based on a visual similarity of the feature to a shadow;
- determining an azimuth value based on the position of the feature in the imagery;
- calculating a compass bearing for a portion of the imagery based on the determined azimuth value, the compass bearing comprising a horizontal coordinate relative to due north;
- and
- associating the portion of the imagery with the calculated compass bearing, the associating comprising determining a sun azimuth associated with a position approximately 180° from the position of the feature.
