摘要
本文提出了一种基于图象Hough变换的矩形检测算法。通过对图象Hough变换空间中峰值点进行提取和组合,检测出满足角度和长度条件的直线组合,以快速定位出图象中的矩形。实验结果表明:该算法快速、准确,检测过程不需人工参与。
This paper proposes a new algorithm for rectangle detection based on Hough transform. Peaks of the Hough image, which correspond to line segments, are extracted, and a rectangle is detected when four extracted peaks satisfy certain geometric conditions. Experimental results indicate that the approach can detect rectangles quickly and precisely.
