iPi Studio Markerless Motion Capture: Deform Test Mocap

This is raw mocap footage created using iPi Studio. This performance will be used to help us with deformation testing for the Brudders short film. (Note: shown here is the default iPi Desktop Motion Capture rig and model, and not a Brudders character. We'll show the Brudders character models in a future video.)

As of this session, iPi Software added shoulder tracking and the ability to capture synchronized video from six Playstation 3 Eye cameras. (We're still using only four cameras here.)

Some jittering is still present but I understand the programmers are working on it. Still no head or wrist tracking, but I'm told that head tracking is planned for a future update.

One curious problem with this test: during 'the twist' motion, the feet become 'unfixed' and rotate with the body. However, the feet and hips seem to be tracking fairly well during 'the circle walk'.

Equipment used for this test: one HP Pavilion Elite computer with an Nvidia Geforce GTX 260 card and a SATA3 secondary drive dedicated to video capture, four Playstation 3 Eye cameras and four active USB repeater cables. With this gear, we were able to easily capture four synchronized streams of 640 x 480 video at 60 fps, fast enough to eliminate most motion blur problems. (Compare with our old equipment used for the Sword Test, which struggled to do four streams at 30 fps.) Calibration with the new computer takes less that 10 minutes, and tracking takes about 2 to 3 seconds per frame. (Tracking speed depends on the graphics card. Upgrading to a GTX 480 or better should improve the speed significantly.)

Thanks! Keep in mind that this test was created using only four PlayStation cameras and an older version of the software. The software today (a year and a half later) is actually much more accurate.

is it needed t pose to begin the tracking?

i didn't expect the model to overlay over the raw video as well as it did, surprising.

How much did you spend on that room? I'm thinking about investing in a mocap thing (educational license ftw) and I'm thinking about iPi, but am obviously on a very limited budget (I have $500 to spend right now but am expecting to get a lot more in the next month). I'm also thinking about building a facial motion capture rig to go along with it.
