Abstract
A display apparatus including light source(s), camera(s), head-tracking means, and processor configured to: obtain three-dimensional model of real-world environment; control camera(s) to capture given image of real-world environment, whilst processing head-tracking data obtained from head-tracking means to determine pose of users head with respect to which given image is captured; determine region of three-dimensional model that corresponds to said pose of users head; compare plurality of features extracted from region of three-dimensional model with plurality of features extracted from given image, to detect object(s) present in real-world environment; employ environment map of extended-reality environment to generate intermediate extended-reality image based on pose of users head; embed object(s) in intermediate extended-reality image to generate extended-reality image; and display extended-reality image via light source(s).
