在高速狀態下,直升機不會有任何不良反應,可能在你慢下來之前,你都不會注意到尾漿已經失效。The contributions of this dissertation is listed below. aiming at existing defects of traditional beeline detection by hough transformation ( ht ) arithmetic, such as large storage space consuming, imprecise beeline detection effect and information loss of image feature pixels etc, we suggest two new beeline detection methods. ( 1 ) based on infinite symmetry exponential filter and its recursion arithmetic, new beeline detection methods can get exact direction of image edge pixels in advance, so it reduces highly the calculation quantity of the conventional ht, and improves the speed and the precision of beeline detection greatly
本論文的主要研究成果列舉如下:針對傳統直線檢測霍夫變換( houghtransform , ht )所存在的參數空間存儲量大,直線檢測不精確以及圖像特徵點信息丟失等缺點,提出兩種新的直線段檢測演算法: ( 1 )提出一種基於無限對稱指數濾波的ht直線段檢測演算法,在進行邊緣檢測的同時,提前精確定位邊緣點的方向,減少了ht的運算量,提高了運算速度和檢測精度,而且整體演算法便於硬體的并行執行,使得實時處理成為可能。
