I've seen very positive review of Dual Kinect capture here

http://nycppnews.com/2012/02/12/joe-her ... re-system/

the quality quite satisfies me for my purposes,

but still I cannot answer myself if sitting pose will be captured as good as standing one?

Could anyone with dual kinect capture experience share some thoughts?

My characters will be sitting in office room and chat around a table ( will not be used for capture ).
So I need correct hand motion capture of sitting person

Jean Dellac captured sitting motions using only a single Kinect with iPi DMC. It starts at around 1:25:

Is this what you mean? If so, dual Kinect would actually be even more stable and accurate.

Though not sitting in a chair like a 'normal people', my characters in Happy Box are all sitting on a sofa. This was a actually an extreme pose (for the hips and legs) but iPi DMC and dual Kinect captured it fairly well. I had to make a slight offset for the hips on the Y but this was due to the fact that my characters are not very 'human' proportioned--in fact, the original iPi avatar was correctly posed without any adjustment. I know this isn't exactly what you want but I just wanted to show that capturing 'sitting' motions is not a problem for iPi with dual Kinect.

Hope this helps.

I can see 6 cameras array in video caption, so it is not one Kinect capture.

I agree, that dual kinect would work, it is just I'd like to get some 'sense' of how good it would be or what limitations are ( if any )

Jean was one of the first iPi artists to post Kinect tests and the 'sitting' sequence depicted here is definitely Kinect capture. In the video he added title cards to explain what the different test footage represents. The first portion of video was captured with PS3 Eye but the test footage starting at 1:25 is Kinect. Later in the video, you many have noticed the Kinect Sensor depth data.

I hope this clarifies the confusion. As for limitations...

The main limitation with Kinect, dual or single, is the smaller capture space and lower framerate. Otherwise capture quality is pretty decent. The six camera PS3 Eye configuration is capable of capturing a much larger space at a higher framerate, but the advantage with Kinect is simplicity in setup and use. I use both systems and currently I favor dual Kinect for capturing most actions. The PS3 Eye setup is excellent but it requires quite a bit more 'fuss' to use. I like to keep it around for special situations. :)

I have found specific joint limitations in the hips/thighs of the iPi actor when twisting the torso which results in the ankles pivoting oddly. But this occurs rarely and can be easily corrected in a 3D program. This is not a Kinect capture issue however, it's a general iPi rig issue. (FYI, the developers have explained that this is not a bug--the rig has certain limits built-in to prevent other potential issues. I'm sure iPi Soft will continue to improve on this.) Other limitations are lack of head tracking and wrist rotation, but these too are not specifically Kinect issues and they can be easily added in 3D animation.

Hopefully this answers your questions.

Thanks for clarification - somehow missed that second text screen in the movie.

OK, now will be moving to the nearest shop to pick kinects ;)

One more thing: limitations depend greatly on what you're trying to capture and the proportions/anatomy of the characters you are applying the data to. I find that for a 'standard' human characters, iPi works quite well with minimal editing required, but for characters with extreme or non-human proportions things can get trickier. This is where a mocap editing program like Motion Builder, Jimmy|Rig Pro, Animeeple and Webanimate can really help.

Hopefully, iPi Soft will consider adding more advanced editing tools in a future release of DMC. (Please?) ;)
