摘要
基于海天背景目标提取技术的研究,提出一种结合canny算子海天线检测方法,首先采用高斯平滑在低分辨率上采用canny算子检测边缘,然后通过直线边缘的方向特性,跟踪边界连接边缘点去除大部分的干扰,最后利用Hough变换拟合海天线;实验证明该方法不仅能够准确快速地提取出海天线,而且还能较好地抑制细小边缘的干扰,在实际应用中取得良好的效果。
Sea--sky--line detection is one of the important components in the guidance techniques of imaging anti--shi Pmissi]e. In this paper the problem of sea--sky--line detection is studied in detail, which is the key technique to improve the adaptability of traciug system. Firstly, we detect edge by Canny operator in the low--resolution through Gaussian smoothing, then based on the directional characters of beeline, follow the boundary and link the beeline edge points, consequently taking out most blur. Finally ~Hough transform is employed to fit the sea--sky--line exactly. The experiment result shows that our algorithm can detect out the sea--sky--line effectively, and has wide a- daptability and high precision.
