What is the cv2.cv replacement in OpenCV3?
提问by Bill Cheatham
I'm using OpenCV3, and with the python bindings there is no cv2.cvmodule:
我正在使用 OpenCV3，并且使用 python 绑定没有cv2.cv模块：
In [1]: import cv2
In [2]: from cv2 import cv
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-2-15a6578c139c> in <module>()
----> 1 from cv2 import cv
ImportError: cannot import name cv
However, I have some legacy code of the form:
但是，我有一些形式的遗留代码：
hsv_im = cv2.cvtColor(image, cv2.cv.CV_BGR2HSV)
When running this, I get the error:
运行这个时，我收到错误：
In [7]: hsv_im = cv2.cvtColor(image, cv2.cv.CV_BGR2HSV)
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-7-e784072551f2> in <module>()
----> 1 hsv_im = cv2.cvtColor(image, cv2.cv.CV_BGR2HSV)
AttributeError: 'module' object has no attribute 'cv'
What is the equivalent of this code in OpenCV3?
这个代码在 OpenCV3 中的等价物是什么？

From OpenCV 2.X OpenCV 3.0 a few things changed.
从 OpenCV 2.X OpenCV 3.0 开始，一些事情发生了变化。
Specifically:
具体来说：
cv2.cvdoesn't exists in OpenCV 3.0. Use simplycv2.- some defines changed, e.g.
CV_BGR2HSVis nowCOLOR_BGR2HSV.
cv2.cvOpenCV 3.0 中不存在。简单地使用cv2。- 一些定义发生了变化，例如
CV_BGR2HSV现在是COLOR_BGR2HSV。
So you need to change this line:
所以你需要改变这一行：
hsv_im = cv2.cvtColor(image, cv2.cv.CV_BGR2HSV)
to:
到：
hsv_im = cv2.cvtColor(image, cv2.COLOR_BGR2HSV)
