这几乎是我们在emgu cv中一直遇到的最大问题之一。首先将dll文件名opencv_core290.dll，open_cvhighgui290.dll复制到您的项目bin，尝试对dll文件使用依赖项跟踪器。从此链接安装依赖项- http://www.emgu.com/wiki/index.php/Download_And_Installation..If它不工作，那么你应该明白，应用越来越与camera.Then连接到我的电脑- >右键单击- >性财产>高级系统设置->系统属性->高级->环境变量->系统变量->路径->编辑->并粘贴C：\\ Emgu \\ emgucv-windows-universal-cuda 2.9.0.1922 \\ bin。然后按OK。重新启动系统，它将起作用。
