Augmented Reality in 2D

Juli 8th, 2009 • ar, computervision, creative, flash, hot, idea, lab, nerdlab

Once again I experimented with webcam, augmented reality and flash. Inspired by camspace.com this time I wanted to see if its posible to map a video on a rect which is moved and resized by colored objects.

Tomorrow I will post a screencast and a demo. so you can see it in action. I can’t post the sources right now but I’m on it.

    Nice one! I’ve noticed sometimes it loses the track of the colour marker, are you using adaptive threshold to accommodate various lighting conditions?

    thanks!
    no i didnt use an adaptive one. i worked with a wide thershold range and a “boundingbox” around the last point position. also i thersholded each color channel seperately.

    the problem is the motion blur when you move to fast. my experience was that even an adaptive threshold didn’t work when you move to fast. but maybe it was just a problem of my average code ;)

    when i tested even a mean shift algorithm didn’t return better results
