After set up the IR projectors on the surface table (aka Maria) in about 15 minutes...
...we took over 2 hours to get some calibration sensibility.
We found out that there were a lot to improve:
1- Diffuser - probably the tracing paper is the better one so far (but if it is on top of the surface [glass] it gets dirty too fast, and if its below the surface it gets air between the surface [producing false bolbs detection]), we need to test a lot more;
2- IR LEDs - probably 4 units are not enough, they have a very narrow angle. We must try them on a different layout;
3- PS3eye - must have a calibration base;
4- Projector - needs to be adjusted for a better reflexion on the surface;
5- Ventilation - it gets a bit warm inside the box, the 2 coolers previously mounted are weak, a couple more holes should do the trick.
But we also know that we are on the right way, yeah!
