Research on Recognition Algorithm of Regular Geometry Based on Corner Detection

目前基于链码特征、霍夫变换等方法的规则几何图形的计算机识别算法,计算量较大,处理时间长,因此本文提出一种基于角点检测的算法,通过提取几何图形的角点个数确定其形状。利用MATLAB进行实验仿真,对圆、三角形、四边形、五边形、六边形和五角星形进行识别,结果表明基于角点检测的规则几何图形的识别算法计算准确,正确率较高。

The computation of regular geometry recognition algorithm based on chain code character or hough transform is heavy,and the time is long,so this paper proposed a algorithm based on corner detection,which obtain the shape by extracting the corners number of regular geometry.The recognition of circle,triangle,quadrilateral,pentagon,hexagon and pentagram is based on MATLAB,and experiment result state that the regular geometry recognition algorithm which based on corner detection were calculated accurately,and the accuracy is higher.
