如何在Cv2中使用Hough圈和python? [英] how to use hough circles in cv2 with python?

问题描述

我有以下代码，我想检测圆.

I have the following code and I want to detect the circle.

   img = cv2.imread("act_circle.png")
   gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
   circles = cv2.HoughCircles(gray,cv2.CV_HOUGH_GRADIENT)

它似乎没有属性，并且错误如下

it looks like it does not have the attribute and the error is the following

'module' object has no attribute 'CV_HOUGH_GRADIENT'

有人知道这个隐藏参数在哪里吗?

Does anybody know where this hidden parameters is?

谢谢

推荐答案

CV_HOUGH_GRADIENT属于cv模块，因此您需要导入该文件:

CV_HOUGH_GRADIENT belongs to the cv module, so you'll need to import that:

import cv2.cv as cv

并将函数调用更改为

circles = cv2.HoughCircles(gray,cv.CV_HOUGH_GRADIENT)
