Abstract
A system for producing extended-reality images for a display apparatus. The system includes camera(s) and processor communicably coupled to camera(s), wherein processor is configured to: control camera(s) to capture image(s) representing test object present in real-world environment, wherein test object is physically covered three-dimensionally with coded pattern; obtain information pertaining to three-dimensional geometry of coded pattern; analyze image(s) to identify first image segment representing part of coded pattern visible in image(s); determine virtual content to be presented for test object, based on said part of coded pattern; process image(s) to generate extended-reality image(s) in which virtual content is virtually superimposed over said part of the coded pattern, based on information pertaining to three-dimensional geometry of coded pattern.
