| Abstract: | To meet the requirement of Synthetic Vision System(SVS) for displaying airport and runway,an airport synthesized vision display method was proposed based on standard airport database and open graphic architecture.Firstly,AMDB data source,format and modeling methodology were analyzed.Then,OSG,an across-platform,open-source graphic processing library,was used to perform 3D vision synthesis for airport,runway and surrounding terrain.The AMDB mapping and modeling method,the synthesis display technology of airport 3D model and terrain were studied emphatically.KSFO airport synthetic vision was established,and vision rendering and travel functions were realized.Simulation environment and simulation cases were designed for this purpose,and the implementation effects of airport and runway 3D visions synthesis are given.It is verified through the simulation that the AMDB modeling method and the airport synthesis & display technology can meet the requirements of SVS in terms of image quality,frame rate,resolution and FOV. |
