This paper designs the flight control and image transmission of the UAV,and combines the PID algorithm with the flight control formula to establish a more stable flight control model.The more powerful STM32F4 series microcontroller is used as the central processor for design,and it is divided into modules and platforms to simulate and realize the functions of UAV flight control,image collection and image transmission.It can not only increase the stability of flight shooting,but also provide a reference for cross-platform flight camera transmission.
