在第二个监视器中显示新窗口，opencv [英] Display new window in second monitor, opencv

问题描述

我在 python 中有一个 opencv 程序，它从网络摄像头获取帧并显示提要.当p"被按下时，它只抓取人脸并在另一个窗口中显示这一帧.

I have a opencv program in python that takes frames from a webcam and displays the feed. When 'p' is pushed, it grabbes just the face and display this one frame in another window.

我想将这个新窗口强加到我的第二个监视器上，而摄像机信号在另一个监视器上——主"监视器.现在它只显示在提要的顶部.

I would like to force this new window on to my second monitor while the camera feed is on the other one - the "main" monitor. Now it just displays on top of the feed.

我一直在寻找和搜索，但除了 moveWindow 找不到其他任何东西.我怎样才能使用这个或另一个函数来做到这一点?

I have been looking and searching but can't find anything else than moveWindow. How can I use this or another function to do this?

希望有人能帮我解决这个问题！

Hope someone can help me one this!

推荐答案

我发现使用命名窗口后跟 moveWindow 允许我将图像推送到我的第二台显示器.-900 向上推动窗口.

I found that using named window followed by moveWindow allowed me to push the image to my second monitor. The -900 pushes the window upward.

def im_show(img, name, time):

     cv2.namedWindow(name)
     cv2.moveWindow(name, 900,-900)
     cv2.imshow(name, img)
     cv2.waitKey(time)

return
