摘要
分析了Tycho-2星表数据文件结构,并运用VC++工具按给定的视轴方向、视场角和星等提取了子星表的信息,为进一步的星空模拟打下基础.
Star map simulation is the essential key part of verifying star point extraction,star identification and attitude solution.In this paper,the data file structure of Tycho-2 star catalog is analyzed in detail,and via VC ＋ ＋ tools the subjected star catalog is extracted,based on the given optical axis pointing,visual fields and star magnitude,favoring the further study of star image simulation.
