Zusammenfassung: | Position tracking system for a head mounted display, comprising at least one image capture device (106, Figure 2) mounted on said head mounted display, processor to perform a calibration process in which it receives image data from image capture device/s in respect of a users environment 201, identifies discernible features 200 therein such as corners, objects and stores a three-dimensional representation of the environment in terms of the discernible features. The processor then receives image data from said at least one image capture device in respect of said users environment, and identifies one or more transformations between the discernible features, comparing one or more transformations with the three-dimensional representation of the users environment, and thereby tracking the position and/or orientation of the head mounted display (100) within the environment. The system may comprise a pair of image capture devices that capture respective images of the environment and the processor defines a depth map. |
