OpenCVSharp for Unity

Community Showcases
1

I’ve seen lots of Youtube videos with people demonstrating using openCV with Unity, but haven’t found many that include demo source code to actually play around and learn.

So I wrote my own Unity demo based on shimat’s openCVSharp wrapper for openCV. In the demo, the user can select a region of interest to track via openCV’s CAMshift algorithm.

The code is open sourced. I’m hoping people can use it to learn openCV for Unity and maybe even suggest improvements in my implementation.

Thanks.

The source and executables are on SourceForge Unity OpenCVSharp Camshift download | SourceForge.net

Oh, many thanks for that. :sunglasses:

Works in Unity free?

Possibly. It only depends on the OpenCVSharp Dlls from shimat’s project. I think Unity free will work, but haven’t tried it.

I’ve significantly updated the code and posted it to Google Code.

Looks like SourceForge is preferable for this: Unity OpenCVSharp Camshift download | SourceForge.net

Works fine for me with Unity 64Bits. Just run with the included scene (openCVtextureScene.unity)
Someone has found tutorials about face detection?

Could you share android build setup? It seems crash on Android device without proper port of OpenCVSharp wrapper.

Thanks!

The openCVSharp libraries and source are at GitHub - shimat/opencvsharp: OpenCV wrapper for .NET.

You’ll need to make sure that the DLL in the Assets directory is built for your platform. So 32-bit or 64-bit depending on your computer. I don’t know about Android, but I’m guessing you can re-build the openCVSharp DLLs for Android.

Hello tbreina!
I am a new user of unity, and I want to use opencvsharp in unity too. But I met problem in building opencvsharp. I want to build DLL for my unity projects, cause DLLs in your project are 32-bit. But I don’t know how to. Could you please give me some advice on this?

We’ve recently made an asset OpenCV plus Unity that extends OpenCVSharp library to Unity. It supports all major platforms: Mac, Windows, iOS, Android for reasonable price. If you have any questions please fell free to ask me.
