Detection of a calibration object for modifying image parameters

A system for identifying image calibration data, the system comprising:

• one or more processors;
• and
• logic encoded in one or more non-transitory computer-readable storage media for execution by the one or more processors and when executed operable to cause the one or more processors to perform operations comprising:
• receiving an original image from a camera, wherein the original image includes at least a portion of a calibration chart;
• deriving a working image from the original image;
• determining regions in the working image, wherein the regions comprise groups of pixels having values within a predetermined criterion;
• analyzing two or more of the regions to identify a candidate calibration chart in the working image;
• identifying at least one region within the candidate calibration chart as a patch, wherein the identifying of the at least one region is based on a color of the patch;
• and
• predicting a location of one or more additional patches based on at least the identified patch.

A non-transitory computer-readable storage medium with program instructions stored thereon, the program instructions when executed by one or more processors are operable to cause the one or more processors to perform operations comprising:

• receiving an original image from a camera, wherein the original image includes at least a portion of a calibration chart;
• deriving a working image from the original image;
• determining regions in the working image, wherein regions comprise groups of pixels having values within a predetermined criterion;
• analyzing two or more of the regions to identify a candidate calibration chart in the working image;
• identifying at least one region within the candidate calibration chart as a patch, wherein the identifying of the at least one region is based on a color of the patch;
• and
• predicting a location of one or more additional patches based on at least the identified patch.
