You need to add OpenCV to your system path:
您需要将 OpenCV 添加到您的系统路径中：
You need to add the directory C:\opencv\build\x86\vc10\bin to your system PATH. This directory contains OpenCV DLLs required for running your code.
您需要将目录 C:\opencv\build\x86\vc10\bin 添加到您的系统路径中。此目录包含运行代码所需的 OpenCV DLL。
Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...
打开控制面板 → 系统 → 高级系统设置 → 高级选项卡 → 环境变量...
On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin; (3), then click Ok.
在 System Variables 部分，选择 Path (1)，Edit (2)，然后键入 C:\opencv\build\x86\vc10\bin；(3)，然后单击确定。

Sometimes you may get this error even when you have added the relevent bin file, for example \opencv-x.x.x\build\install\x64\vc15\bin, to the System Path Environment Variable.
有时，即使您已将相关 bin 文件（例如\opencv-x.x.x\build\install\x64\vc15\bin，添加到系统路径环境变量），也可能会收到此错误。
In my case, it worked once I rebooted my PC. Or maybe just restart visual studio and see if it's working, before you reboot the system.
就我而言，一旦我重新启动我的电脑，它就起作用了。或者，也许只是在重新启动系统之前重新启动 Visual Studio 并查看它是否正常工作。
