Hey all,

I'm part of research team planning on taking Kinects up on a microgravity parabola aircraft for some testing. Our plan is to have three different systems capturing data and to evaluate which was the best method. The data we are looking for are the angles between points on the subject (major joints on body). My question is, does iPiSoft have anything that could do that for me? I was reading somewhere here that iPiSoft has a point cloud export? All I would really need is the raw data points (x,y,z) and I could write a simple Excel macro to calculate the angles between the vectors.

I just want to know before we shell out and buy the software (Would the dev team be interested in sponsoring us? ^_^ ). We already have an application that is written with the Kinect SDK to calculate angles between points on the skeleton model. It's pretty low fidelity that's why we are looking at something else in addition. iPi looks to be one of the few applications that is for the Kinect. If iPiSoft can't give me this data, I'd still like to use it for outreach purposes when we are trying to explain to people what we were doing. It would be a good visual aid.


Thanks in advance.

P.S. I posted this in the help forum too, I just wanted to get some more opinions. Not sure which gets the most traffic.

Oddly enough I am working on a extremely similar research project. I am an undergraduate student at the University of Michigan working also on validating the the accuracy of the Kinect for motion capture compared to the 3D mo-cap system the University has and compared to a system developed by a grad student here that is able to caputure motion with mutiple 2D cameras. What I did was, I used iPi Recorder to to record the video and iPi DMC to process it. I then saved it as a bvh file. Using another program called BVH viewer I was able to save the BVH file into a text file that had the 3d xyz coordinates for all 27 points for however many frames were there in the video. I then made a program in matlab that read the text file and calculated the angle in each frame for whatever joints I wanted. So it is very possible.

That's great news, sorry for my late reply. Is iPi DMC the same as "studio" or something else?

iPi DMC (Desktop Motion Capture) is the name of the system as a whole package.

iPi Studio is the calibration/tracking/retargeting part of DMC; iPi Recorder, of course, is data capture part.

I guess you could also throw in the hardware and accessories as the rest of the 'DMC package'. :)

Thanks for the replies folks, can't wait to get working with iPi.
