I have connected the computer vision / blob tracking software to the laser so now with proper lighting conditions the laser will draw your outline as you dance around in front of it. It works best if the wall is a solid color and brightly lit so the thresholding operation can pick up your outline. I am currently experimenting with various curve generalization algorithms to help clean up the image in cases where parts of the outline are missed.
I am testing the camera setup in the hallway in Elings in preparation for displaying the project at the end-of-year-show.
I also took the laser to Santa Barbara City College for a demonstration on 05/19/09.
