摘要/Abstract

摘要： 数字天顶仪是一种高精度大地天文测量仪器，在进行星图识别时计算量较大，效率较低。考虑到在拍摄的恒星星图中存在着相同恒星，对恒星像点轨迹进行了理论推导，研究了星图中相同恒星的区域，并提出一种基于恒星像点轨迹的快速星图识别方法。该方法只结合星表对单个定位循环中间的一幅星图进行识别，其余星图采用该星图识别出来的恒星再进行识别，可简化恒星星表，减少了参与识别的恒星数量，使星图识别更具有针对性，从而提高了星图识别的效率和速度。试验结果表明，采用快速星图识别方法识别的恒星数量满足定位要求，且定位精度与运用恒星星表进行星图识别解算的精度基本一致。

Abstract: Digital zenith camera is a high-precision astronomical positioning instrument. It takes star images in different orientations by rotating. The stars in each star image are identified by using star catalogue. But the calculated amount is very large and the efficiency of star identification is low. Considering that there are many same stars in the star images, the trace of one star point is deduced, and the region of the same stars is studied. A new star identification method is proposed. In the proposed method, only one star image needs to be identified by using star catalogue. The identified star can be simplified as a new star catalogue, which can be used for the rest star images. Thus the efficiency and speed of the star identification get improved. The experimental result shows that the number of stars identified by the fast star identification method can meet the requirements of positioning, and its positioning accuracy is basically the same as that of star identification method.
