Design of Cricket Automatic Control System Based on Computer Vision Technology

This paper designs a cricket control system based on computer vision technology. This system is controlled by PID algorithm. The acquisition system is OpenMV camera, and the processing system is STM32 series MCU. The design is used to control the small ball to roll on the evenly distributed smooth square plate, so that the ball can be removed on the square plate without any external force except for the self-gravity, the support force of the plate and the friction force. Various specified requirements are fulfilled between circular areas of 3 cm in outer diameter. In this design, the image data is collected by the camera on the smooth flat panel range, and the collected data is transmitted to the STM32 core board through the serial port for processing, and the center coordinates of the hard ball are found through the processed data, and the coordinates are adjusted according to the set destination coordinates and the actual coordinates. PID (proportional-integral-derivative) controls the steering gear to rotate a certain angle to control the hard ball to achieve the relevant operational requirements.
