Ue5 opencv plug-in use

This plug-in is free ,UE5EA Personal test is valid , Thank you, senior friends , I won't thank you one by one here .

The plug-in for ：OpenCVforUE5 plug-in unit - Internet document resources -CSDN download

1. The source code for

GitHub - Brandon-Wilson/OpenCV-Plugin: A simple OpenCV plugin that integrates the OpenCV library into UE4. The plugin includes some blueprint classes that demonstrate how OpenCV can interact with the engine.

2. Project configuration

After decompressing Binaries、Plugins、ThirdParty The folder is directly copied to the root directory of the project

3. modify ProjectName.Build.cs

// Copyright Epic Games, Inc. All Rights Reserved.

using UnrealBuildTool;
using System.IO;

public class TestWebcam : ModuleRules
{
	private string ThirdPartyPath
	{
		get{return Path.GetFullPath(Path.Combine(ModuleDirectory,"../../ThirdParty"));}
	}
	public TestWebcam(ReadOnlyTargetRules Target) : base(Target)
	{
		PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
	
		PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore","OpenCV"});

		PrivateDependencyModuleNames.AddRange(new string[] {  });

		// Uncomment if you are using Slate UI
		// PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });
		
		// Uncomment if you are using online features
		// PrivateDependencyModuleNames.Add("OnlineSubsystem");

		// To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true
		string OpenCVPath = Path.Combine(ThirdPartyPath, "OpenCV/");
		PublicIncludePaths.AddRange(new string[] { Path.Combine(OpenCVPath, "Includes") });
		PublicLibraryPaths.Add(Path.Combine(OpenCVPath, "Libraries/Win64"));
	}
}

4. modify OpenCV.Build.cs

// Some copyright should be here...

using UnrealBuildTool;
using System.IO;

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

	//public OpenCV(TargetInfo Target)
	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 
        string LibPath = "";
        bool isdebug = Target.Configuration == UnrealTargetConfiguration.Debug && BuildConfiguration.bDebugBuildsActuallyUseDebugCRT;
        if (Target.Platform == UnrealTargetPlatform.Win64)
        {
            LibPath = Path.Combine(OpenCVPath, "Libraries", "Win64");
            isLibrarySupported = true;
        }
        else if (Target.Platform == UnrealTargetPlatform.Win32)
        {
            // TODO: add OpenCV binaries for Win32
        }
        else if (Target.Platform == UnrealTargetPlatform.Mac)
        {
            // TODO: add OpenCV binaries for Mac
        }
        else if (Target.Platform == UnrealTargetPlatform.Linux)
        {
            // TODO: add OpenCV binaries for Linux
        }
        else
        {
            string Err = string.Format("{0} dedicated server is made to depend on {1}. We want to avoid this, please correct module dependencies.", Target.Platform.ToString(), this.ToString()); System.Console.WriteLine(Err);
        }

        if (isLibrarySupported)
        {
            //Add Include path 
            PublicIncludePaths.AddRange(new string[] { Path.Combine(OpenCVPath, "Includes") });

            // Add Library Path 
            PublicLibraryPaths.Add(LibPath);

            //Add Static Libraries
            PublicAdditionalLibraries.Add("opencv_world320.lib");

            //Add Dynamic Libraries
            PublicDelayLoadDLLs.Add("opencv_world320.dll");
            PublicDelayLoadDLLs.Add("opencv_ffmpeg320_64.dll");

        }

        Definitions.Add(string.Format("WITH_OPENCV_BINDING={0}", isLibrarySupported ? 1 : 0));
	}
}

5. modify OpenCV.cpp and OpenCV.h

//.cpp
//#include "OpenCVPrivatePCH.h"
#include "../Public/OpenCV.h"


//.h
//#include "ModuleManager.h"
#include "Modules/ModuleManager.h"

6. stay VS Project settings

Right click on the item -> attribute ->VC++ Catalog , stay Include Add a path to the directory ：../../ThirdParty/OpenCV/Includes
