Wand technique

Post by Imperitus »

Okay I'm just getting started with this stuff so I'm just looking for rules of thumb at first.

When using the wand to do the initial calibration, which is more important, full coverage of the area, or keeping the point in all the cameras views at all time?

Ideally, both, as the camera overlap is what allows the system to current see the movement within the 3d capture area.

Hah, I knew and feared I'd get that response. :) I'm trying for both, my wanding technique just isn't there yet.

Have you looked at the wanding video we have posted?

In general, try to make sure the cameras are all pointing toward the same region (center of the capture volume) and that your body does not block the marker from any of the cameras when wanding.

I have watched the video. That's the technique I'm trying to mimic. I'm just not very good at it yet. I think I'm going to rig up a projector shot the screens at the wall so I can see my lines as I draw while I practice, untill I can get good solid coverage.
