阈值分割法在直升机驾驶舱模拟器中的应用研究

通过对直升机起降特点及视角转换的分析研究,建立模拟起降模型。以VC++为工具,采用双缓冲技术及光栅处理技术,解决了驾驶舱图片透明化过程中存在的闪烁问题。在完成驾驶舱透明化处理的基础上通过采用阈值分割方法_1],实现了驾驶舱与跑道在同一窗体不同区域中的显示,通过组件调用的方式完成驾驶舱按键对飞机起降的控制,并结合多线程技术完成了直升机模拟起降的仿真测试。该方法能直观清楚的反映直升机起降过程中驾驶舱内部及外部跑道的情况,对直升机起飞降落故障研究有一定的参考价值。

The landing of helicopter simulation method based on threshold segmentation research

Through the analysis of the helicopter landing characteristics and perspective transformation, establishing a simulation model of the landing of helicopter. With vc + + as a tool, adopting double buffer technology and processing technology of grating has solved the cockpit picture flicker problems exist in the process of transparency. On the basis of the completion of the cockpit transparent processing , using threshold segmentation method achieves the cockpit and the runway shows in different regions of the same form. Through the way of component calls complete the aircraft cockpit buttons controlling the landing of helicopter, and combined with multithreading technology to complete the simulation of helicopter landing simulation test. This method can directly reflect clearly the helicopter cockpit inside and outside the runway in the process of takeoff and landing, the flying helicopter fault study has certain reference value.
