| 摘 要： | 研究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直线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.仿真实验结果表明,该算法比Hough变换能更准确、快速、可靠地提取图像的直线特征.

| Abstract: | Investigates a fast algorithm of line feature extraction.Divides the edge into several sub-edges in one direction and detect lines from sub-edges according to the line extraction criterions.Then merges 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 with the Hough transform. |
