Collaborative sighting

A apparatus comprising:

• a first camera unit configured to generate first image data;
• a processor coupled to the first camera unit;
• a memory storing instruction that when executed by the processor cause the processor to perform operations including:
• generating calibration data by geometrically calibrating first image data from the first camera unit relative to second image data from a second camera unit based on first descriptor data and second descriptor data, wherein the first descriptor data is based on the first image data, and wherein the second descriptor data is based on the second image data;
• identifying, based on the calibration data, a target location relative to the first image data;
• and
• generating an output image, wherein the output image includes the first image data and an indication of where the target location is relative to a scene depicted in the first image data.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• generating calibration data by geometrically calibrating first image data from a first camera unit relative to second image data from a second camera unit based on first descriptor data and second descriptor data, wherein the first descriptor data is based on the first image data, and wherein the second descriptor data is based on the second image data;
• identifying, based on the calibration data, a target location relative to the first image data based on the calibration data;
• and
• generating an output image, wherein the output image includes the first image data and an indication of where the target location is relative to a scene depicted in the first image data.
