Opencv中不支持的数组类型错误
本帖最后由 lovelylucky 于 2018-10-13 10:19 编辑小菜鸟一枚，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
import numpy as np
import cv2
# Create a black image
img = np.zeros((512,512,3), np.uint8)
# Draw a diagonal blue line with thickness of 5 px
img = cv2.line(img,(0,0),(511,511),(255,0,0),5)
cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()却得到了如下错误：
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
Traceback (most recent call last):
File "/home/dccv/rec 2.py", line 17, in <module>
cv2.imshow('img',img)
cv2.error: /build/buildd/opencv-2.3.1/modules/core/src/array.cpp:2482: error: (-206)
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
import numpy as np
import cv2
# Create a black image
img = np.zeros((512,512,3), np.uint8)
# Draw a diagonal blue line with thickness of 5 px
cv2.line(img,(0,0),(511,511),(255,0,0),5)
cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()
