Non-contact measuring device of object size and shape based on OPENMV

This system takes STM32F103 as the MCU, combines OPENMV image processing module, two-dimensional pan tilt, laser ranging module, key input module, TFTLCD display module and acousto-optic module to design a non-contact measuring device of object size and shape. The device uses OPENMV, STM32 MCU and Two dimensional pan tilt to form a closed-loop feedback control system. According to the feedback information of OPENMV image processing, STM32 uses PID algorithm to control the steering gear to correct the pitch angle and heading angle, so that the OPENMV camera is facing the center of the object. Openmv continues image processing to identify the shape of the object. The laser ranging module measures the distance between the object and the measured object. Finally, the binomial curve equation fitted by MATLAB data and related data measures the size of the object. Through the actual test, the system has good performance and stability.
