Method and system for maintaining color calibration using common objects

A method of color calibrating an augmented reality display device, the method comprising:

• estimating a real-world illuminance;
• capturing an image of a real-world object, identifying the real-world object and accessing known color characteristics of the real-world object;
• computing a candidate color rendering of a synthetic version of the real-world object using the real-world illuminance and the color characteristics of the real-world object;
• displaying the candidate color rendering beside the real-world object using an AR display and recording an image of the display containing both the real-world object and the candidate color rendering;
• and
• adjusting a display color model used for rendering synthetic content based on a calculated difference between the image of the real-world object and the image of the displayed candidate color rendering.

An apparatus for color calibrating an augmented reality display, the apparatus comprising a processor configured to perform at least:

• estimating a real-world illuminance;
• capturing an image of a real-world object, identifying the object and accessing known color characteristics of the real-world object;
• computing a first candidate color rendering of a synthetic version of the real-world object using the real-world illuminance and the color characteristics of the real-world object;
• computing a second candidate color rendering of a synthetic version of the real-world object using the real-world illuminance and the color characteristics of the real-world object;
• displaying both candidate color renderings beside the real-world object using an AR display and prompting a user to indicate a preferred color rendering;
• and
• in response to the user indication, updating a display color model used for producing future candidate renderings and synthetic AR content based on characteristics of the indicated rendering.
