基于区域方差和RANSAC的海天线检测新方法

针对海空背景图像中海天线的检测问题,提出了一种基于区域方差和RANSAC算法的新方法.该方法首先搜寻图像中设定区域内方差最大值的位置,并以此确定出若干海天线候选点坐标,然后结合RANSAC算法求取海天线直线参数.实验证明,该方法能有效地检测出复杂海空背景下的海天线,具有鲁棒性强、运算速度快、工程实用价值高等优点.

A New Method of Sea-sky-line Detection Based on Region Variance and RANSAC Algorithm

Aim at the problem of sea-sky-line detection in sea-sky background image,a new method which is based on region variance and RANSAC algorithm is proposed.First,position of maximal variance in each predefined region in the image is hunt out,and coordinates of some possible sea-sky-line points are made certain according to the position,then line parameter of sea-sky-line is solved combined with RANSAC algorithm.The experimental results show that this method can detect out sea-sky-line under complicated sea-sky background effectively,and has many advantages such as strong robustness,speedy calculation and high practical value.
