Abstract
Described herein are systems and methods for maintaining color calibration using common objects. In an exemplary embodiment, an AR system includes a forward-facing camera, an AR display, a processor, and a user interface. The processor is configured to receive image data from the forward-facing camera and identify any known objects depicted in the image data. The processor then determines RGB information at least one test rendering of the identified known object and displays it via the AR display. Input from a user interface, indicating which of the at least one test renderings was a closest match to the real-world object, and a level of satisfaction with the match are received by the processor and used to update an AR display color calibration model. More test renderings may be iteratively provided to improve the accuracy of the calibration.
