In order to better demonstrate the simulation results of the unmanned helicopter flight control a multi-channel visual simulation platform was developed for unmanned helicopter flight control.This platform used three channels to demonstrate the simulation results on a big screen.Visual C++6.0 was used for programming of the software Creator was used to establish unmanned helicopter models and flight scenes and Vega was used to display the visual effect.The system consisted of three computers three projectors and two joysticks which could realize the transmitting and synchronizing of multi-channel visual simulation data.Unmanned helicopter flight on this platform proved that the multi-channel visual simulation system is better than the traditional display of the visual system on visual effect.
