Design of UAV 3D Visual Simulation System Based on X-Plane

After the research and analysis of the existing UAV 3D scene simulation system, it is learned that the most commonly used simulation system is the hardware-in-the-loop simulation, but this kind of hardware-in-the-loop simulation has some shortcomings, such as that the workload of building is relatively large, and the resources used are relatively large. Therefore, this paper designs a 3D visual simulation system of UAV based on X-Plane, which mainly includes three parts: as a simulation demonstration environment, X-Plane can better show the flight state of UAV, and puts forward its own method on how to load a user-defined UAV model in X-Plane. The digital aircraft uses UDP communication protocol to communicate with X-Plane and SITL with MAVProxy (UDP) to interact with the control platform. As a middleware, it connects the control platform and X-Plane. PID control algorithm and area coverage route planning method of parallel line segmentation are used in the control platform, which can send control commands to UAV, such as takeoff, landing, hovering, etc.
