摘　　要：提出了一种提取并定位不规则直线的方法.将Hough算法和数学形态学结合在一起,利用Hough算法对直线敏感的优点及数学形态学运算简单准确的特点,避免了Hough算法不能准确定位直线的位置,同时不能判断间断直线和微小弯曲直线的缺点.减少了提取的盲目性和计算的复杂度,加深了对图像的理解.In this paper, we present a new algorithm for extracting irregular line segment, which combines Hough algorithm with mathematical morphology opertor. Hough algorithm are more specially dedicated to the long and straight line segment extraction, and are not sensitive to irregular line. Based on Hough algorithm, we apply mathematical morphology operator, which can locate irregular line segment accurately, this proposed method is less blind and reduces the computation complexity.
