expanding triangle 中文意思是什麼
-
Fully autonomous layered star identification algorithm, which divides the detected stars to lbs and lds, gives priority to lbs in making star triangle and identification, so can find the matching star quickly. it takes the maximum matching reliability and expanding index at the edge of na to reduce the influence of position error, magnitude error and fake star, so have high identification correct rate. it can be used for full and local sky star identification
全天自主分層星識別演算法，採用分層的方法，以局域亮星為主構造和識別觀測星三角形，減少了待識別的觀測星三角形數量，具有較高的識別速度；採用最大匹配可信度和索引的邊緣擴充方法，可以在一定程度上解決位置誤差、星等誤差和偽星干擾等問題，具有較高的識別準確率；既可以進行全天自主星識別，又可以進行局部星識別。
