SYSTEMS AND METHODS FOR TRACKING OBJECT LOCATION AND ORIENTATION IN VIRTUAL REALITY ENVIRONMENTS USING ULTRA-WIDEBAND SIGNALS, INERTIA MEASUREMENT UNITS, AND REFLECTIVE MARKERS

摘要

Systems and methods for tracking object location and orientation in VR environments include: fixed position ultra-wideband transceivers transmitting within a physical space and receiving reflections of those transmissions; mobile objects located within the physical space, at least one of the mobile objects including one or more light-reflective tracking markers that reflect the ultra-wideband transmissions of the transceivers; one or more cameras mounted to at least one of the mobile objects, each camera including a wireless communication module; a processor in communication with the transceivers and the wireless communication modules of the cameras; and a memory in communication with the processor, the memory storing program instructions that, when executed by the processor, cause the processor to: calculate the position of each mobile object using the reflections received by the transceivers in combination with the information received from the one or more cameras mounted to each mobile object.
