Hola,

Just viewed your Siggraph footage of the the guy doing Cappoera(sp?) - is that kind of movement possible with an 8 camera set up?

I have an 8 camera setup and I've rarely done a full take without seeing red body parts and it's driving me nuts!
Is there a recommended set up? I have wood floors is that a bad thing? I'm trying to figure out what's what but it's a little rough sometimes.

My space is 18 x 12 - if I were able to find a space where I could move the cameras further out would that help with the accuracy? I have windows but I close the blinds, would I need to cover them up as well?

If I were to put up MORE cameras (let's say 12) in the same space would that make things more accurate? Or would you say I'd STILL would probably need a larger space?

Also, when you take off/put on the MOCAP suit, do you readjust the markers everytime or leave them on? Would larger markers help with accuracy?


Thanks

I'll see if I can cover a few of these -

I think they used either a 12 or 16 camera setup, at Siggraph. with a setup area of 20' * 20'

The wooden floors could cause an issue, if they are seeing the IR reflections of the other cameras

Moving out would help with increasing the capture volume itself, as the 18' * 12' side is going to give you a usable side of only 9' * 6' capture volume. You can try and improve this a little, by rotating some of the cameras 90 degrees.

If the cameras are seeing IR light, thru the window blinds, you nmay need to cover them up a little more.

12 cameras will help with object tracking, and reduce occlusion, but a combination of both slightly larger volume and cameras is always a good idea.

If you are using the 5/8" marker set, they will work just fine with set volumes out to 20' * 20'. As for the suit, they generally leave them on, and adjust if necessary, once the suit is on. (taking a photo, with a good marker placement helps with placement if they do get askew)

I would also recommend checking the calibration file, and try running it at 150 data points, and at medium capture speed, while trying to cover as much of the capture volume as possible, even if the results aren't excellent.
