：给出了一种新的Hough 变换圆检测方法——点Hough 变换（PHT）。该方法根据圆周上任意两条不平行弦的中垂线相交与圆心的几
何性质，同时选取曲线上3点 进行计算，将传统Hough变换圆检测时的三维参量统计变成一维参量统计，极大地降低了计算复杂性和对资源的需求。为了克服任意选取组合点可能带来的计算量增加及统计结果的分散程度提高,文中提出了点的选择方法。合成图和实际图像的实验结果表明，该方法用于普通图像中圆检测时快速、稳定、准确。-: This paper presents a new method of Hough transform circle detection- point Hough transform (PHT). The method according to any circle on the two parallel strings do not intersect with the vertical center of the geometric properties, select the curve at the same time to 3:00, the traditional Hough transform circle detection parameters when the three-dimensional into a one-dimensional statistical parametric statistics, greatly reduces the computational complexity and demand for resources. In order to overcome the combination of any selected point of the calculation of the potential increase in the dispersion results and the degree of increase in the points raised in the text of the selection method. Synthesis of maps and images of the actual experimental results show that the method can be applied to general image circle detection in rapid, stable and accurate.
