海天线上舰船定位算法研究

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.

An Algorithm for Locating Naval Ships on the Sea-Sky-Line

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.
