Abstract: A mobile object tracking system has one or more imaging devices for capturing images of a site, one or more reference wireless devices in wireless communication with one or more mobile wireless devices (MWDs) via one or more wireless signals, and one or more received signal strength models (RSSMs) of the site for the wireless signals. Each MWD is associated with a mobile object and movable therewith. The system tracks the mobile objects by combining the captured images, the received signal strength (RSS) observables of the wireless signals, and the RSSMs. The system may calibrate the RSSMs at an initial stage and during mobile object tracking.
