Opencv中不支持的数组类型错误

lovelylucky

小菜鸟一枚，确定所有的的东西都正确安装了但是当我想绘制图像时：例如：这段代码取自Python openCV tutoria

1. import numpy as np
   
2. import cv2
   
3. # Create a black image
   
4. img = np.zeros((512,512,3), np.uint8)
   
5. # Draw a diagonal blue line with thickness of 5 px
   
6. img = cv2.line(img,(0,0),(511,511),(255,0,0),5)
   
7. cv2.imshow('img',img)
   
8. cv2.waitKey(0)
   
9. cv2.destroyAllWindows()

复制代码

却得到了如下错误：

1. OpenCV Error: Bad flag (parameter or structure field) (Unrecognized or unsupported array type) in cvGetMat, file /build/buildd/opencv-2.3.1/modules/core/src/array.cpp, line 2482
   
2. Traceback (most recent call last):
   
3. File "/home/dccv/rec 2.py", line 17, in <module>
   
4. cv2.imshow('img',img)
   
5. cv2.error: /build/buildd/opencv-2.3.1/modules/core/src/array.cpp:2482: error: (-206)
   
6. Unrecognized or unsupported array type in function cvGetMat

在window和ubuntu同样都有这样的错误

第6行：不将img变量设置为返回值，而是忽略返回值

1. import numpy as np
   
2. import cv2
   
3. # Create a black image
   
4. img = np.zeros((512,512,3), np.uint8)
   
5. # Draw a diagonal blue line with thickness of 5 px
   
6. cv2.line(img,(0,0),(511,511),(255,0,0),5)
   
7. cv2.imshow('img',img)
   
8. cv2.waitKey(0)
   
9. cv2.destroyAllWindows()
