kinect tracking suggestion

pixelschub's icon

hello max fellows,

i want to start an interactive project with the kinect.
the goal is to track 2 skeletons with my xbox kinect without doing the “psi” pose.

did a research and found out, that are many possibilities to do this.
mac versus win, openni versus mirosoft sdk, xbox versus windows kinect and so on.

i have tested several apps, which send osc messages with the skeleton data.

something as kinecta is what i am looking for:
http://kinecta.mihoo.de/

but it crashes often on my mac.

i am looking for some hints from people with experience at this field.
can someone suggest a simple and stable solution. mac or pc. (mac prefered)

thanks in advance,
pixelschub

jit.openni for Max is great.
SimpleOpenNI for Processing too.

thank you very much dtr and matmat for your hints !
i think i will go the jit.openni route.

dp.kinect is not an option, because it is not clear how much it will cost after the beta period.
information from the dp.kinect website :
"Current Beta version is v0.6.5 with an expiration date of 28 Mar 2013."

Hi everyone,

I didn't think you could do skeleton tracking without the pose?

I hope I am wrong on this as it would be great!

can jit.openni do this?

with jit.openni it is possible.
i am doing it right now :-)

does anybody has made a simple 3d model (jit.gl.sketch?? ) in jitter, which represents the skeleton coming out of jit.openni ?

i have found: the Viewskeletons patch, but it is a bit different.

it is using ./osceleton as a input base.

What I do is simply put the skeleton coordinates in a 15x1 matrix and run that into a jit.gl.mesh in point drawmode. I don't need more visualization than that. I'd share it with you but it's embedded in a larger patch, no time to extract right now. Very easy to replicate though.

Btw, I'd largely prefer jit.openni to output the joints as a matrix rather than the messages it does now.

DTR, I realize that patch may have disappeared into the ether, but if it's still kicking would you be willing to share it?

I'm starting to grind on a kinect project using the v1 and it'd be really helpful.
