我正在尝试开发一个代码来识别空圈数之间的实心圆.

我已经在中心纵坐标中识别出每个圆圈.如何检测哪个圆是空的以及哪个圆被填充？

我已经开发了这段代码

import numpy as np
import cv2
import math

img = cv2.imread("small.jpg",0)
img = cv2.medianBlur(img,5)
cimg = cv2.cvtColor(img,cv2.COLOR_GRAY2BGR)

circles =cv2.HoughCircles(img,cv2.HOUGH_GRADIENT,1,60,param1=50,param2=30,minRadius=0,maxRadius=0)

circles = np.uint16(np.around(circles))
counter=0
correctC=[]
xC=[]
yC=[]

for i in circles[0,:]: 
    #cv2.circle(cimg,(i[0],i[1]),i[2],(0,255,0),2)
    #cv2.circle(cimg,(i[0],i[1]),2,(0,0,255),2)
    cv2.putText(cimg,str(i[0])+","+str(i[1])+","+str(i[2]),(i[0],i[1]), cv2.FONT_HERSHEY_SIMPLEX, 0.3,(255,0,0),1,cv2.LINE_AA)
    correctC.append((i[0],i[1],i[2]))
    xC.append(i[0])
    yC.append(i[1])
    counter+=1

print "Circle Count is : " + str(counter)

xCS=sorted(xC)
yCS=sorted(yC)
xS=sorted(correctC, key=lambda correctC:correctC[0])

q1=sorted(xS[:4],key=lambda correctC: correctC[1])
q2=sorted(xS[4:8],key=lambda correctC: correctC[1])
