基于最小二乘法的曲线导航线提取算法

A Curve Guidance Directrix Algorithm Based on Least Squares Method

针对视觉导航中的曲线导航线提出了一种基于最小二乘法的导航线提取算法。首先通过图像分割将原始图像转化为二值图像,其中导航线对应像素点标记为1,再通过最小二乘法拟合这些导航线对应的像素点得到导航线方程。实验结果表明新算法不仅能较好的提取曲线导航线而且对直线导航线也能适用。

A curve guidance directrix algorithm is proposed for machine vision guidance which is based on least squares method.The original image is first segmented to binary image and pixels labeled 1 correspond to guidance directrix.And then the guidance directrix equation is processed based on least squares method with guidance directrix pixels coordinate.The results shows that new algorithm have good efficient for curve guidance directrix and linear guidance directrix.
