The Design of High Precision and Visual Simulation Platform of the Unmanned Helicopter

In recent years, the simulation platforms of unmanned helicopter usually express the flying state with data or curves. The flight display animation is rough, cannot accurately express the information of flight status. According to the present situation, this paper puts forward a way to build the high precision and visual simulation platform of the unmanned helicopter. It is using Visual C++ to write the software of the interface, parameter identification method to build the mathematic model with LeiHu Raptor 60 helicopter as model, 3Dmax to establish the helicopter animation model, Direct3D to realize the map making of flying scenes and the rendering of planes and environment, and Matlab as engine server to deal with motion equations and controller equations. The three dimensional animation intuitively shows the flying state, then greatly meets the needs of the visual analysis.
