主权项

1. A system comprising:
a video surveillance subsystem comprising a plurality of cameras each having a field of view, each field of view comprising a plurality of sub-regions; a radio-frequency identification subsystem comprising a plurality of radio-frequency stations, each radio-frequency station configured to detect radio-frequency identification tags within a respective operational radius; and an association module in communication with the video surveillance subsystem and the radio-frequency identification subsystem, the association module for inferring associations among one or more of the sub-regions and one or more of the operational radii, wherein inferring the associations comprises:
determining a first probability that a first one of the sub-regions is associated with a first one of the operational radii based on a detection of a tracked object in both the first sub-region and the first operational radius at a first time; anddetermining a second, higher probability that the first sub-region and the first operational radius are associated based on a detection of a tracked object in both the first sub-region and the first operational radius at a second, later time.
