Implementation of embedded system for vehicle tracking and license plates recognition using spatial relative distance

Abstract

This paper set out to use a camera attached to a mobile terminal in order to inquire a car and track its location anywhere. The technology based in the research is to automatically recognize and verify license plates on the front and back of a car. The plates are input through a camera attached to a mobile terminal. The technology enables us to detect a car registration number and to transmit it along with the location of the terminal to a server through a wireless communication network. The information of a car obtained through the terminal is encoded and transmitted to a server in a remote place through a wireless communication network. The car registration number and its location information are decoded and transmitted as a text to the server in a remote place. In order to track a user's location through spatial relative distance estimated in real-time, the server uses the spatial and attribute information which are the most prior to the desired data value. With this property information, the right location can be calculated.
