This is an iPi DMC video of a session I did a few days ago. This performance will be used to help us with deformation testing for the
Brudders short film.
iPi Studio: Deform Test Motion Capture We're using the latest build but with just four PS3 cameras. We probably won't start testing six cameras until after we finish our film.
Some jittering is still present here even though I used one pass of the new Jitter Removal. One problem I've had with the Jitter Removal is that it's very aggressive with small intended motions. Because of this I'm going to avoid using it for most of the motions in our short film. Hopefully the jitter problem gets resolved in time for our next project. I think the level of Trajectory smoothing her was 2.
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.)
Overall, I'm very pleased with the new software. Keep up the great work guys! :)
