| As an important tool of controlling, monitoring and simulation training ofunmanned aircraft vehicle (UAV), ground control station (GCS) is given more and moreimportance nowadays. The three dimensional synthetic vision, the virtual aviationinstrument, the data storing and playback technology, the generation of simulation datatechnology and etc are gradually applied to GCS systems. Currently, the technique ofobtaining faster operation, more intuitionistic data display and more flexible datainterface has become the hotspot in the UAV ground station area.This article analyzes the blend of three-dimension (3-D) vision and head-updisplay screen, flight data visualization techniques and radar imaging simulationtechnology. In view of the requirement in practical application, simulation software iswritten. The main work and contributions of the article are as follows:（1）First of all, the overall design, the system configuration, the functionalrequirement and implementation status of each module of the UAV ground station isintroduced.（2）Second, method of loading3-D terrain, adding collision detection andassociating movement model using Vega Prime software under the VC++environmentis researched. After that, by overloading the VP channel class and adding the graphicsprocessor, the blend of3-D vision and OpenGL HUD screen is realized.（3）Thirdly, the combination drawing frame of the MFC WinControl and OpenGLis established. On this basis, the UAV instrument is created and the flight datavisualization is achieved by introducing the Measurement Studio instruments.（4）Then the network transmission and the real-time play of video signals arerealized. Using and MFC transparent window mechanisms and memory cache imageoutput technology, the blend of character ruler and video screen is achieved.（5）At last, based on the raw data acquisition of VP3-D vision and the scanningsimulation of UAV radar, the output simulation of the simplified radar image isimplemented. |
