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.%为了更好地演示无人直升机飞行控制的仿真效果,开发了无人直升机飞行控制多通道视景仿真平台,该平台使用3个通道在弧形大屏幕上演示仿真效果.软件部分使用Visual C++6.0编程,利用Creator软件建立无人直升机三维模型和飞行场景,采用Vega软件实现动画显示效果.硬件部分由3台计算机、3台投影仪和2个控制杆组成,实现多通道视景仿真数据的传输及同步,以及三通道视锥配置,并实现三通道渲染场景的无缝拼接.通过无人直升机在此平台上的飞行仿真证明,该多通道视景仿真系统比传统视景系统的显示效果更为突出.
