Abstract
An optical display system has an optical waveguide combiner and one or more cameras. The one or more camera(s) is optically coupled to the optical waveguide combiner and have a field of view of at least one real object and at least one virtual object displayable by the optical display system. The one or more camera(s), which may be for example wafer level waveguide camera(s), may be disposed outside the usable field of view of an output coupler. The one or more camera(s) may be self-calibrated electronically using images captured by the cameras of one or more virtual object(s) displayable by the optical display system. AR/VR/MR registration of devices and/or displayed virtual objects with real objects may be implemented using the images captured by the one or more camera(s) of the displayed virtual objects and real world objects. Real object distance and/or spatial location relative to the optical waveguide combiners may be determined or estimated from the captured images.
