2020 Electronic Competition G Question-Non-contact Object Size and Shape Measurement (Liaoning Petrochemical University)

Through the analysis of the structure and characteristics of the measurement and control system, combined with the modern control technology design concept, a gesture recognition system with the microcontroller STM32 series microcontroller and the visual processing camera openmv as the core was realized. The color and shape information of the target object is collected through openmv, and a variety of data processing methods are used to identify the object's perimeter, color, shape and other information and then display the above information through the LCD. The working process is: collect the color shape of the item through openmv and filter it and send it to stm32. The controller processes the data and then displays the calculation results on the LCD. In the search mode, it drives the servo to scan from left to right until the target is found, aligns the camera center with the geometric center of the target, and performs identification.
