cv2.imshow 命令在 opencv-python 中无法正常工作 [英] cv2.imshow command doesn't work properly in opencv-python

问题描述

我使用的是 opencv 2.4.2、python 2.7以下简单代码创建了一个名称正确的窗口，但其内容只是空白且不显示图像:

I'm using opencv 2.4.2, python 2.7 The following simple code created a window of the correct name, but its content is just blank and doesn't show the image:

import cv2
img=cv2.imread('C:/Python27/03323_HD.jpg')
cv2.imshow('ImageWindow',img)

有人知道这个问题吗?

推荐答案

imshow() 仅适用于 waitKey():

import cv2
img = cv2.imread('C:/Python27/03323_HD.jpg')
cv2.imshow('ImageWindow', img)
cv2.waitKey()

(更新窗口所需的整个消息循环都隐藏在那里.)

(The whole message-loop necessary for updating the window is hidden in there.)
