A video surveillance system is integrated with an RFID tracking system. The calibration
of the RFID tracking system is enhanced by using information provided by the video
surveillance system. Optionally, the calibration of the video surveillance system
may be enhanced by using information provided by the RFID tracking system. Calibration
of the RFID tracking system is facilitated by placing RFID tags at visually apparent
locations in a surveillance area and using the location information determined
from the video surveillance system to determine appropriate correction factors
for use in subsequent RFID location determinations. Dynamic performance is also
calibrated by placing RFID tags on visually apparent moving targets and using the
location information determined from the video surveillance system to determine
the parameters used to qualify subsequent RFID location estimates of moving targets.
