A Method for the Fusion of Results from RFID and VLPR

Abstract Radio Frequency Identification (RFID) and Vehicle License Plate Recognition (VLPR) are two main methods for vehicle identification. How to fusion the recognition results of is a problem that needs be solved in practice. The existing technology usually uses trigger acquisition precise matching, or one result as reference perform matching another set, while these does not provide clearly algorithm has certain limitations, universal. A presented this paper, which takes advantage similarity metric between from RFID VLPR, thus eliminating drawbacks match methods. calculates VLPR by license plate character graphics similarity, then find specific time window, finally work out similar result. simple but effective, with no need triggering simultaneously. can output both matches matches. Through verification real road scene, performance calculation process consistent expectations, shows effectiveness algorithm.
