Route Identification in Intelligent Traffic System Based on CMOS Image Sensor

This paper introduces a method based on image processing technology, which allows model car to identify the route on a white board. Our system uses MC9S12XS128 as the control unit, CMOS camera is applied to capture data, and H-bridge driver circuit supports the motor. In addition, we use the ultrasonic to calculate the distance and wireless data transmission module to protect the car from a crash. Finally, we establish an algorithm which controls the car and recognize dotted lines in order to overtake the other model car at speed-change area.
