An intelligent tracking-vehicle control system based on STM32 is developed to achieve quick identification and accurate tracking of specific target in real-time. Acquire image information of target using OV7670 after graying

de-noising and reverse processing the image

obtain target coordinates by the centroid subpixel positioning technology to provide direction navigation for intelligent vehicle

and picture of target can be sent to host computer during tracking process. The experimental result shows that the system has a good tracking effect and can achieve real-time accurate and tracking of target.
