Image recognition technology and optimized control algorithm of the self-tracing smart car based on CMOS camera sensor

As an intelligent system, the self-tracing smart car contains a core of MCS12 micro control unit (MCU) of Freescale. Acquiring useful information provided by a CMOS camera, the system can recognize the pathway and give proper parameters, as well as choosing optimized control algorithm for image acquisition, noise filtering, shape reforming, PID or fuzzy logical control and memory methods for precise control of the servo and driver motors. Experiments demonstrate that this car has a good ability to regulate direction along pathway and to response acceleration. So it can successfully complete the race as fast as possible in the diverse competition.
