    Yesterday and today I had some fun with an exercise for university. It is starting right now and the first thing to do was to train the camera with parameters to follow a pattern and draw upon that pattern a cube (in light blue)...

    I found it cool and thought I could share some of the results.

    Click on the picture to see a short screencast where I'm moving the piece of paper around and the cube follows like a little dog.




    I look like scary, but since everything in the video looks crappy I don't care Wink

    That's cool. You had to write the recognition code?

    Until now I have only used some software and gotten some parameters and added them into a short script. The thing to calibrate the camera is build upon the Intel Open Source Computer Vision Library. The software that prints the output is called "Studierstube" and builds upon OpenTracker.

    But as said the exercise just started. This was the first thing to do. More is to come Smiley

    Looks cool!

    Are you going to make a .Net lib out of it? Wink

    Would be fun, wouldn't it? Right now the thing builds upon OpenGL. You also see it in the script language. It's very much OpenGL like.

    That's awesome!

    Next step: a camera on LCD goggles so that you can augment reality in a VR sort of way.

    Very cool, how many things can you track/recognise at once and how well does it work in low-light conditions?

    I once saw a video in the middle of a city, and the guy zoomed in on a big advertisement poster. But instead of the advertisement, the computer recognized the large square and showed a list of his emails.

    The video that you see has been recorded in the evening... I haven't tried it with very low light, but since my camera allows you to switch into a low light mode it would also be possible to do it. But as a prof said: if you have no light you can't use cameras to detect anything. You're blind then.
