星图

Some quilters like to reproduce old-fashioned designs such as the traditional star quilt pattern that you see in this picture.

有些缝制者喜欢重制旧式设计，如：照片所示的常规星图。

You can find the Adromeda galaxy by using the Great Square of Pegasus, as shown on this chart.

或者你也可以通过星图所显示的通过仙后座来找到仙女座。

In partial celestial sphere celestial Star-Identification, the initial attitude is known. With a certain angular and distance tolerance, the separation angle of the observed stars and that of the catalog stars are matched, then, the star triangles are composed in real time. According to the rules of vector rotation, the inconsistent rotation star triangles are removed. After that, put the star triangles with public vertex into star polygon.

在局部天球星图识别方面，因为已知初始姿态，在一定角距容差和星对容差范围内和已知视轴附近的导航星角距表进行角距匹配，实时组成星三角，根据矢量法则剔除旋转方向不一致的星三角后，再把拥有公共顶点的星三角组合成星多边形。

Kuehl's triangle Star-Identification, some improvement had made. With a certain angular and distance tolerance, the separation angle of the observed stars and that of the catalog stars are matched, then, the star triangles are composed in real time. According to the rules of vector rotation, the inconsistent rotation star triangles are removed. After that, put the star triangles with public vertex into star polygon.

Kuehl的三角形星图识别的基础上进行了改进，即在一定角距容差和星对容差范围内和整个导航星角距表进行角距匹配，实时组成星三角，根据矢量法则剔除旋转方向不一致的星三角，把拥有公共顶点的星三角组合成星多边形。
