基于改进Hough变换的直线检测方法研究

Research on the Method of Line Detection Based on Improved Hough Transform

Hough变换不仅可以用来检测规则的直线,也可以对其他许多形状的物体进行识别,但由于阈值设定的问题对短直线的检测会受到长直线的影响而效果不好,且该变换仅检测直线,无法记录检测直线的起始点和终止点。为此,该文提出一种改进过的Hough变换算法更好的检测遥感图像中的直线。

Hough transform can be used not only to detect straight lines, but also to identify many other objects. However, due to the problem of threshold setting, the detection of short straight line will be affected by the long straight line and the result is not good. And the transformation only detects the straight line, and can not record the starting point and ending point of the detection line. For this reason, this paper proposes an improved Hough transform algorithm to detect straight lines in remote sensing images better.
