OPENCV+PYTHON

解决方案可以看这个:

http://answers.opencv.org/question/18135/opencv-error-assertion-failed-sizewidth0-sizeheight0-in-unknown-function/

window.cpp:304:error: -215 size.width>0 && size.height>0 问题的解决，我的原来代码是这样的:

import cv2
import numpy as np

img = cv2.imread("1.jpg")
emptyImage=np.zeros(img.shape,np.uint8)
emptyImage2=img.copy()
emptyImage3=cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
cv2.imshow("EmptyImage3",emptyImage3)
cv2.waitKey(0)
cv2.destoryAllWindows()

修改后问题就不存在了

import cv2
import numpy as np

img = cv2.imread("C:\\Users\\Administrator\\Desktop\\opencv\\1.jpg")
emptyImage=np.zeros(img.shape,np.uint8)
emptyImage2=img.copy()
emptyImage3=cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
cv2.imshow("EmptyImage3",emptyImage3)
cv2.waitKey(0)
cv2.destoryAllWindows()
