Virtual Whiteboard: Using LabVIEW and Kinect

Using the Kinect's depth sensor, we created a LabVIEW application to make a virtual whiteboard. As you get close enough to the Kinect it will track where you are and overlay it on the video image. You can change the color of the drawing as well as the threshold for picking up where to draw.

This is awesome! How long did it take you do program this application in LabVIEW?

[noiz77]

@grantheimbach it took about 1-2 to get a working prototype, and then another 5-6 hours to get to this point. the tough parts were getting the overlay to work. we found out if you do an overlay and then flip the image, the overlay disappears, so we had to merge the overlay before flipping the image with IMAQ.

Admit it, that's basically a hello world app when you're writing stuff for kinect, is it?

Nice work guys! Thanks for sharing your LabVIEW project with the rest of the engineering community.

If you care to share any code and technical details, check out the LabVIEW Robotics Code Exchange (nidotcomslashcodeslashrobotic­s). A bunch of people have shared their LabVIEW+Kinect projects there as well.
