[0031] introduction

[0032] Methods and systems for maintaining color calibration using common objects are disclosed herein. Such methods and systems may be implemented as processes occurring in an AR system, such as an AR HMD or an AR server, and as the AR system itself. Various embodiments take the form of procedural methods. In embodiments described herein, a calibrated forward-facing camera or spectrometer continuously captures image data of a real-world scene of the AR system. In some embodiments, a camera system (or alternatively a second camera system) is inside the AR glasses and can detect the real world scene as well as the inserted synthetic imagery. The controlling processor of the AR system communicates with a color database of known objects, such as products, signs, and e...

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.

Description

[0001] Cross References to Related Applications [0002] This application is a non-provisional application and claims the benefit under 35 U.S.C. § 119(e) of the following application, filed December 29, 2017, entitled "Method and System for Maintaining Color Calibration Using Common Objects." Calibration Using Common Objects), U.S. Provisional Patent Application Serial No. 62 / 612,140, ​​which is hereby incorporated by reference in its entirety. Background technique [0003] The purpose of color calibration is to measure and / or adjust the color response of a device (input or output) to known states. In International Color Consortium (ICC) terminology, this is the basis for an additional color characterization and subsequent profiling of the device. In non-ICC workflows, calibration sometimes refers to the one-off establishment of a known relationship to a standard color space. Color calibration is a requirement for all devices that are an active part of a color management wo...
