UnrealCV is an innovative project designed to assist computer vision researchers in the creation of virtual worlds using Unreal Engine (UE). This powerful tool enables interaction with virtual environments and connects them with external programs, such as Caffe. Whether you’re a novice or an experienced user, this blog will walk you through the installation process and the initial steps to harness the capability of UnrealCV.

Understanding UnrealCV

Think of UnrealCV as a magical doorway that leads you into immersive virtual worlds. Once you step through this door, you can interact with these environments—not unlike a video game character exploring a richly detailed landscape. UnrealCV allows you to command the objects and settings in this world using a variety of powerful commands, simplifying complex computer vision tasks.

New Features in UnrealCV

• Call any Blueprint function from Python using the command:

  vbp [obj_name] [func_name] [arg1] [arg2] ...

• Support for RPC communication between Server and Client on Linux, allowing for a higher frame rate and more reliable performance.
• A wealth of new commands for camera control and object manipulation. Check the command system for details.

How to Install UnrealCV

Installing UnrealCV is straightforward. Below are the steps to get you started:

1. Download the source code and place it in the Plugin folder of your C++ Unreal Engine project.
2. Open Visual Studio 2019 and launch your C++ project; UnrealCV will compile together with it.
3. To verify a successful installation, run the command

   vget unrealcvstatus

   in the console (press ~ to display the console).

For those interested in using UnrealCV as a client, simply run the command:

pip install unrealcv

Troubleshooting Installation Issues

If you encounter any issues during installation, here are some troubleshooting tips:

• Ensure that you have the correct version of Unreal Engine installed.
• Verify that Visual Studio 2019 is properly set up with the necessary components for C++ development.
• If the status command fails, check your plugin directory to ensure the UnrealCV files are in the correct folder.
• For persistent issues, refer to the official documentation for detailed guidance.
