OpenCV integration
Hello Developers!
I am a unity developer trying my hands on opencv for the first time. My initial goal is to run the camera and detect blobs via opencv in unity3d. I am new to OpenCV and am trying to integrate it in Unity3D (on Windows 8 with Unity 4.3.2 and on a mac with Unity 4.2.1f). I followed this thread. But I am getting the following error as soon as I add a new C# script. And the moment I delete this script, the error goes (this script is Unity generated C# script).
Internal compiler error. See the console log for more information. output was: Unhandled Exception: System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded. at (wrapper managed-to-native) System.Reflection.Assembly:GetTypes (bool) at System.Reflection.Assembly.GetTypes () [0x00000] in :0 at Mono.CSharp.RootNamespace.ComputeNamespaces (System.Reflection.Assembly assembly, System.Type extensionType) [0x00000] in :0 at Mono.CSharp.RootNamespace.ComputeNamespace (Mono.CSharp.CompilerContext ctx, System.Type extensionType) [0x00000] in :0 at Mono.CSharp.GlobalRootNamespace.ComputeNamespaces (Mono.CSharp.CompilerContext ctx) [0x00000] in :0 at Mono.CSharp.Driver.LoadReferences () [0x00000] in :0 at Mono.CSharp.Driver.Compile () [0x00000] in :0 at Mono.CSharp.Driver.Main (System.String[] args) [0x00000] in :0
I couldn't find much about Unity and OpenCV integration. It would be great if you could help me out with this error and point me to a recent tutorial to learn more.
Thanks in advance!
Could you describe in more detail how you attempted to include OpenCV in UNity? What are your target platforms?
Did you have a look at EMguCV, which is a C# wrapper for Opencv?
Problems you will face when using EmguCV with UNity will be
its dependence on System.Drawing, which, e.g., maps OpenCv datastructures, but is native win
requires NET 3.5, whereas Unity supports only Net 2.0 and Net 2.0 subset (which appears to be a Unity specific thing)
I guess what needs to be done is:
Remove from EmguCV all calls which require NET 3.5
Replace all calls to methods in System.Drawing with calls to win independend implementations of, e.g. OpenCv datastructure (Point, Rect, ....)
Also have a look at this diagram: http://www.emgu.com/wiki/index.php/Main\_Page#Architecture_Overview
Hi guys,
a colleague of mine made this :
https://github.com/Alex0216/UnityOpenCVExample/wiki
which was very useful in our project.
Best of luck !
