在道路图像边缘检测中,为实时、有效地从获取图像中提取出路面边界,研究了一种结合数学形态学的道路图像边界检测算法.形态学是一种从集合的角度来刻画和分析图像的图像处理和分析理论,其算子的性能主要以几何方式进行刻画,更适合于视觉信息的处理和分析.对采集到的原始道路图像经由图像预处理、道路边缘检测后,应用特殊结构元素对得到的二值图像进行形态学处理.保障"有用信息"比例的同时,去除了大量冗余和干扰信息,减少了边缘信息总量,减轻了后续运算的压力.最后采用Hough变换对腐蚀后图像进行处理,以实现道路边界的精准定位.和未采用腐蚀运算而直接对初始边缘检测后图像进行Hough变换的效果相比,能精准、有效地提取出道路边界线,并且大大地提高了算法的实时性.

To extract the road edge frome road images effectively,the morphology algorithm in road edge detection is discussed.The morphology theory processes images in view of geometry and set theory,suitable for visual information processing and analysis.After image preprocessing and Sobel detection,the algorithm processes the binary image by morphology theory.It can reduce the total amount of edge information,while maintaining useful information proportional.The Hough transformation is used to the corrosion images for the precise location.Compared with the algorithm not using morphology processing,it reduces the computing time,and also can extracts the road edge effectively.
