一种新的直线提取算法研究

研究了一种快速的图像直线提取算法。将边缘按方向划分成若干子边缘,利用判据从子边缘提取出局部直线,然后依据准则合并相应子边缘得到全局直线及参数。准确提取出图像中的直线特征及端点和方向等参数。实验结果表明,算法比Hough变换更准确、快速、可靠地提取图像的直线特征。

A New Line Extraction Method Research

To investigate a fast algorithm of line feature extraction.Divide the edge into some sub-edges in one direction,detect lines from sub-edges according to the line extraction criterions,and then merge the lines that conform to the incorporation criterion.The line features and their parameters are accurately obtained.Simulation results indicate that the proposed algorithm is more precise,speedier and reliable in line extraction than Hough Transform.
