| Abstract: | Vehicle positioning is a key technology for reverse car search in intelligent car parks. Camera positioning and card positioning are not widely used because of the high cost or the poor responses from users. A solution which takes advantage of the radio frequency （RF） location technology to achieve vehicle positioning is proposed for the increasing popularity of electronic licenses. This paper first introduces the basic principles of RF location based on the reference tags, and then the method of layout readers and tags in a park is proposed. The accuracy of location is greatly improved by further subdivided RSS! value and the fusion of the RF location information, and the ultrasonic sensor information. Simulation results show that the RF location is a reliable technology for vehicle positioning. |
