Abstract
Systems and methods for identifying new radio frequency identification (RFID) tag events within a particular vicinity of an RFID reader are described. In various aspects, a processor causes image sensors to capture a first set and a second set of video images, where the first set depicts a first RFID tag environment and the second set depicts a second RFID tag environment. The first RFID tag environment is static without a person moving within the first RFID tag environment and the second RFID tag environment is active with at least one person moving within the second RFID tag environment. An environment database may be generated and updated with static analytic information and active analytic information based on the first set and second set of video images, respectively. The processor may determine a RFID tag event based upon the static analytic information and the active analytic information.
