Some Problems about Kinect's skeleton animation

[Jiaxiang Zheng]

Hey, guys!  How are you, sorry for disturbing here...

I am currently using the skeleton data captured by a Kinect to animate a human mesh (which is also captured by moving the kinect around the model), but I have some problems in doing this. Now I am asking for help, since I am new here, so sorry for disturbing you all again.

I get the mesh and using the approach proposed in siggraph 2006 to automaticlly get the skeleton[namely "SkelA"] fiting to the mesh. And when someone is acting in front of the Kinect, I can get the motion skeleton data by using GetSkeletonCap[namely this skeleton "SkelB"]. 

Now I am transfering the motion of "SkelB" to "SkelA" to animate the mesh. Thus, I should compute every joint's position and orientation, my problem is how to get the relatively accurate orientation data according to "SkelB".

My current method is as follow:

Assume joints A, B which makes a bone, their original position is P1, P2, the current position is P1', P2', then I can compute the rotation between P1-P2 and P1' - P2', using this rotation data to compute the orientation. I know it's not sufficient because of the only 1 DOF, So I am asking for help here...

Thanks a lot here...

Could you please explain this further.  I am trying to understand the transfer of SkelA to SkelB.  I would like to know how you are trying to do this.

Could you please provide a link of the approach proposed in siggraph
2006 ?

Thank you.

Best regards,

I could not find an approach proposed in siggraph 2006.  Do you know where to find it?

[Jiaxiang Zheng]

I feel really sorry to reply you now... The method is proposed in ClickHere which appears in Siggraph2007.  Sorry for the mistake.

Sorry for the mistake I have made, the paper is in siggraph 2007 named <Automatic Rigging and Animation of 3D Character>.

Best regrads,

Jiaxiang
