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.
