本文详细介绍了如何在Visual Studio 2017环境下，将OpenCV集成到Unreal Engine 4.20.3中。首先从GitHub下载OpenCV-Plugin，然后在UE4编辑器的插件设置中启用Computer Vision中的OpenCV选项并重启。接着解决在VS中编译时的错误，修改opencv.build.cs文件。完成这些步骤后，成功导入OpenCV并可以进行后续测试。

1.在建立c++文件后导入插件https://github.com/Brandon-Wilson/OpenCV-Plugin
2.在ue4中edit->plugins中滑到最后勾选computer vision中的opencv中的enabled(这一步一定要先勾选好否则后面会报错）然后重启
3.在vs中编译，报错后把插件中的opencv.build.cs文件改成这样

using UnrealBuildTool;

public class OpenCV : ModuleRules
{
    private string ThirdPartyPath
    {
        get { return Path.GetFullPath(Path.Combine(ModuleDirectory, "../../../../ThirdParty/")); }
    }

    public OpenCV(ReadOnlyTargetRules Target) : base(Target)
    {
        // Startard Module Dependencies
        PublicDependencyModuleNames.AddRange(new string[] { "Core", "RHI", "RenderCore" });
        PrivateDependencyModuleNames.AddRange(new string[] { "CoreUObject", "Engine", "Slate", "SlateCore" });

        // Start OpenCV linking here!
        bool isLibrarySupported = false;

        // Create OpenCV Path 
        string OpenCVPath = Path.Combine(ThirdPartyPath, "OpenCV");

        // Get Library Path
