整数参数预期int在opencv中浮动 [英] Integer argument expected int got float in opencv

问题描述

我已经显示了下面的代码，但是当我尝试执行它时，得到

I have displayed the code below, but when I try to execute it, get

Traceback (most recent call last):
  File "/home/decentmakeover2/Code/cv.py", line 22, in <module>
    img = cv2.circle(img,center, radius, (0,255, 0), 2)
TypeError: integer argument expected, got float

我不完全确定问题是什么，在 minEnclosureCircle 中，值已转换为 int，但我仍然遇到相同的错误，关于可能的任何想法是问题吗?

Im not exactly sure what the problem is, in the minEnclosingCircle the values have been converted to int, but i still get the same error, any ideas on what might be the problem?

import numpy as np
import cv2
import os
from scipy import ndimage

img = cv2.pyrDown(cv2.imread('img.jpeg'))
ret, thresh  = cv2.threshold(cv2.cvtColor(img.copy(), cv2.COLOR_BGR2GRAY), 127, 255, cv2.THRESH_BINARY)
image, contours, heir = cv2.findContours(thresh, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)

for c in contours:
    x, y , w, h = cv2.boundingRect(c)
    cv2.rectangle(img, (x,y), (x+w, y+h), (0, 255, 0), 2)

    rect  = cv2.minAreaRect(c)
    box = cv2.boxPoints(rect)
    box  = np.int0(box)
    cv2.drawContours(img, [box], 0 , (0, 0, 255), 3)

    (x,y), radius = cv2.minEnclosingCircle(c)
    center = (int(x), int(y))
    radius = int(radius)
    img = cv2.circle(img, center, radius, (0,255, 0), 2)

cv2.drawContours(img, contours, -1, (255, 0, 0), 1)   
cv2.imshow('contours',img)
cv2.waitKey(0)
cv2.destroyAllWindows()`

推荐答案

修改你的代码如下你不需要使用cv2.circle的返回值.

Modify your code as follows you do not need to use return value of cv2.circle.

cv2.circle(img,center, radius, (0,255, 0), 2)
