摘要
针对成像型反舰导弹所获光学图像目标的特点,提出了一种海天线上舰船目标定位算法.该算法利用Can-ny边缘检测算法和OTSU算法对图像进行预处理,再利用投影法检测出海天线及舰船图像的上边缘,进而用一元线性回归方程拟合得到海天线方程,最后利用海天线信息定位海天线区域中的舰船目标.实验结果表明,该方法能够有效地确定海天线以及舰船目标在海天线区域中的位置,并且计算量小于已有的方法.
Features of optical image target obtained by imaging anti-ship missiles are studied, and an algorithm to locate the naval ships on sea-sky-line is presented. Firstly, the image preprocessing is taken by applying Canny edge detection and OTSU algorithm. Then the sea-sky- line and naval ships upon edges are obtained by projection. The sea-sky-line equation is reached using one-dimensional linear regression equation. The naval ships positions can finally be located from the sea-sky-line area. The experimental result showed that the method can locate the naval ships positions from the sea-sky-line area efficiently and correctly, requiring less time than existing methods.
