The image of a license plate is scanned by the camera attached to a mobile PDA device and the numbers on the plate are detected by the image processing parts in the proposed Mobile system. Then the numbers and the location of a mobile PDA device are encoded and transmitted along with the location information to a remote server through a wireless communication network. Finally, the server decodes the transmitted data as a text format and transmits it to the destination user. Consequently, this paper contributes a case study on the embedded system for designing of intelligent interface between a moving vehicle and a mobile PDA device, using a spatial relative distance scheme. The experimental results show that detection and tracking of a location of moving vehicle can be conducted efficiently with a mobile PDA device in real-time through wireless communication system and Internet.
