I. Introduction
Multi-rotor target tracking of airborne vision sensing devices has strong application requirements in many fields, such as military, transportation, and natural disaster prevention. Therefore, An application technology research based on multi-rotor target tracking system. Multi-rotor master control uses Pixhawk open source flight control system, peripheral GPS module, SBUS receiver, power supply, driver and other modules. Openmv3 comes with a high-speed processor of the STM32F7 system, directly driving the PTZ, Image processing realized identification and tracking of specified targets, and adopted adaptive fuzzy PID algorithm to make the PTZ follow the tracking target of the camera.
