Retroreflective-marker tracking hardware for physical props (granted).
Abstract
Systems, methods, and devices are disclosed for tracking physical objects using a passive reflective object. A computer-implemented method includes obtaining a location profile derived from content capturing a passive object having a reflective surface reflecting one or more real-world objects. The passive object is attached to a physical object. The method further includes transmitting the location profile to a simulation device. The method further includes generating a virtual representation of the physical object based on the location profile of the passive object. The method further includes presenting the virtual representation in a simulation experience.
