Design of road tracing navigation control for smart car use CCD sensor

A road tracing hardware and navigation algorithm for smart car is designed based on CCD vision. The road image is obtained by CCD, and is been processed within full-line, regional searched and key points selected to calculate the route curve, and the route curve is classify for difference control strategy. Depending on the different curve of route, the corresponding control strategy is selected. An intelligent vehicle tracing algorithm which is based on PD control is designed. Through practice, this algorithm can made the smart car run stably and rapidly, even if the guide line of the road is complex.
