Are there any examples with OpenCV Augmented reality on android? I have found one example for iOS and one real good example in c++. I am not that familiar yet with C++ or OpenCV so I'm looking for a nice example for Android I can follow. -What i mean by Augmented Reality is to simulate an object by putting it onto a pre-defined surface (not a marker). The app would use the camera frames to look for the surface and then draw the object onto the camera frame.-edited

Here you can find the C++ example. I haven't got it working yet so I can't say if it's working properly.

Here you have a sample for Android. You can also used directly the code of C++ version, with native calls: doc.

That sample is just changing the whole frame it's not augmented reality or am i missing something?

Without entering in a complex (and useless?) discussion on what is or what is not ''augmented reality'', I (personally) think that the alien face is augmented reality. Nevertheless, let us know what ''kind'' of augmented reality you want and we can provided some resources.

You are probably right of it being Augmented Reality. But i'm looking for a way to simulate/draw an object onto a surface that is pre-defined. As an example this picture:

This code is easy to port to Android. The implementation is pure C++, and things you have to do are: 1) create a java canvas to see the results 2) use ORB/FAST instead of SIFT/SURF which are unfree and then slightly more complicated to exploit under Android plateform. 3) upload a picture of your object to track or create a java interface to take a picture and resize it to keep only the ''marker''.

Some of my students have do it recently, the performances aren't too bad, but the C++ OpenGL usage to display the cube isn't the best way in my opinion...

Enjoy and let us know!
