Abstract：In recent years,the electronic competitions of university students begin to march from the intelligent vehicles to the unmanned aerial vehicles(UAVs),such as UAV path following and target tracking.Focusing on the four-axis UAV automatic tracking system in university student electronic competitions,an intelligent flight control system based on STM32 as the main controller has been independently designed.This system integrates artificial intelligence(AI)technology into UAV control,adopts the OpenMV camera for visual recognition,and sets the target color threshold in the vehicle LAB color space through Python programming to achieve accurate identification and autonomous tracking of objects with specific colors.Endowed with the unique advantage of three-dimensional space,unmanned aerial vehicle(UAV)systems not only provide diverse innovative entry points and high-value technical challenge scenarios for college student electronic competitions,but also serve as an important technical support for the field of automatic search and rescue.
