问题描述

OpenCV或Emgu CV桌面捕获选项中是否有任何功能?(插件，库，类)，所以我知道我们可以通过一种非常简单的方式来捕获摄像机，是否可以通过这种方式进行桌面捕获?

Is there any function in OpenCV or Emgu CV desktop capture options? (addons, libs, classes) So I know we can capture camera in a very easy way, is there any option for desktop capturing that way?

推荐答案

我建议在Emgu之外(即，在非Emgu C ++/C#中)进行屏幕捕获.

I would recommend doing a screen capture outside of Emgu (ie, in non-Emgu C++/C#).

第一步是从屏幕图像创建位图.有很多网站详细介绍了如何执行此操作的方法.我发现这很有帮助.

The first step is to create a bitmap from the screen image. There are plenty of websites detailing methods of how to do this. I found this one helpful.

一旦有了位图，就很容易从中创建新的Emgu Image<，>.这是该文档.

Once you have a bitmap, it's easy to create new Emgu Image<,> from it. Here's the documentation for that.

祝你好运，玩得开心！
