摘要
针对随机Ｈｏｕｇｈ变换（ＲＨＴ）在处理复杂图像时随机采样造成的大量无效累积提出一种改进的用于直线检测的ＲＨＴ，较好地解决了无效累积问题，并使改进后的算法具有计算速度更快。
To solve the problem of a large amount of useless accumulations yielded by random sampling by means of the randomized Hough transform (RHT)in handling complex images,an improved RHT used to detect lines was proposed. It uses gradient direction information, not only can well solve the problem of useless accumulations, but also has higher speed ,smaller storage and better detection performance.
