I got the projector back in the spring, planning to do some projection mapping. I got distracted by some stuff for a festival, but some co-workers and I were talking about structured light scanning recently, so I threw this together.

For software, I’m probably going to do the calibration stuff in Python and OpenCV. I’d like the first demo to be perspective correction, to project on non-flat surfaces. Second will probably be virtual lighting.

I’m doing a little augmented reality work for my day job, using ARToolKit. ARToolKit works, and is documented, which is a combination of features that appears to be unique in open-source augmented reality software.

I configured my build to use GStreamer, and set my ARTOOLKIT_CONFIG environment variable to v4l2src device=/dev/video0 use-fixed-fps=false ! ffmpegcolorspace ! capsfilter caps=video/x-raw-rgb,bpp=24,width=640,height=480 ! identity name=artoolkit ! fakesink

That gives a good tradeoff between resolution and speed, and works just fine with the simpleLite demo program that comes with ARToolKit.

Augmented Reality is like normal reality, but better
