Design and Production of Tracking System based on OpenMV Image Recognition

Based on the OpenMV open machine vision module, the image recognition and tracking system is studied. The designed intelligent three wheel car is based on STM32F765VI single chip microcomputer, combined with ov7725 photosensitive element, L298N motor drive module, motor and other peripheral equipment. The algorithm of gray scale, filter, binarization, dilate and erode is used to process the image. With the help of OpenMV IDE software and OpenMV's own image processing library, the small ball tracking function is realized by PID algorithm. Setting different experimental environment to test the tracking system, the car can accurately and quickly track the small ball of a specific color block.
