Friday, August 27th, 2010This is my work so far. The construction of the box (80x80x80cm) itself is done. I’ll add some eye-candy (color, lights, etc.) later on. The plexiglas is 10mm thick and completely transparent. Right now I’m waiting for the “lee density frost” diffuser surface, wich will be mounted beneath the plexiglas as a projection surface (and to spread the IR evenly).
I soldered the IR leds to a circuit board and hooked them to a pc power supply (12V). The tracking device is a Sony DCR TRV digital 8 camcorder with nightshot. It’s connected through firewire and will get a wide-angle (0.4x) and just to make sure an IR filter. Its DV resolution and the high FPS will give me some good results in the tracking.
The beamer uses a wide-angle lens, too… but probably still needs to be aligned with a mirror to get the proper image size on top.
WHAT I AM DOING NOW: Testing different frameworks (reacTIVision, CCV, touchlib) to get the best results in blobdetection. Building stands for the IR spots, camera, beamer etc… setup hardware.
