Aiming at the existing track model car easy to lose the line, easy to go off the track out of the problem, this paper carries out the intelligent track monitoring car model of the software program part of the design as well as intelligent track monitoring car parts of the overall design debugging and analysis and other aspects of the research. The design adopts MK60 as the core microprocessor, uses CMOS image sensor OV7725 digital camera to collect road conditions, and processes the road surface information to get the road surface guidance information. Through the guidance information of the road surface to guide the stable driving of the tracking monitoring vehicle, the control system real-time closed-loop control of the corner and speed of the tracking monitoring vehicle, and based on the road surface information and the measured corner and speed information for PID control. The experiments show that the tracking vehicle can be driven stably under the given experimental route, and has better speed and control accuracy.
