Video reference tracking accuracy of iPi Rig and 4 PS Eyes. (Move controllers not used).
Video Link:
http://youtu.be/H7wzSv-gHkcStudio set up in a sun-room on West side of home, recorded before noon, with straw slat blinds, which creates full back lighting with minimal ground shadows and works well for me.
Contrasting clothing worn, then after actor analyzing performed, the arms, feet and hair color saturation was darkened a bit, seems to work better for tracking. (hands, face, top shirt and pants left as iPi analyzed).
Floor grid shown set properly, so reference video of feet aligned very closely to grid and actors feet on ground plane, if this isn't done, you will experience poor tracking and deformation of the legs and feet the further away, or closer you move to/from camera 1, when USE GROUND GRID box is checked, GUARANTEED!
You can uncheck Use Grid box, but I prefer to use it and have my grid set properly, it helps in foot tracking accuracy.
If your camera locations that appear in the calibration video DO NOT match very closely to where they are in-world, your calibration is wrong and you WILL have difficulties in aligning actor and with the tracking process. (You can see the cams in reference video match in-world camera location, My experience).
The actor should align very closely in height and position in at least 2 cameras, (I use the 2 front facing cameras, set as Cam 1 and 2 and Cam 1 set at 1.50 m (51 in.) above ground, rest are 2.438 m (8 ft.) above ground, but after calibration, iPi Studio shows them as 1.50/2.76 m, but that don't matter, because they appear exactly in video where they need to be and floor is properly set).
Some minimal manual advance forward key setting was used and then those areas ONLY, were refined forward, as that method causes jitter, refining forward eliminates it completely.
Applied to legs and head, 1 step of smoothing and arms applied 1 step of sharpening, rest were left default.
Applied 3 steps of trajectory smoothing to get the final result showed.
(When using 4 PS Eye Cams, if you need to use a lot of smoothing and jitter removal, then your tracking its self probably wasn't tracked well, in all my tests I had to use minimal jitter and trajectory smoothing)--(Using Kinects you may experience this needing to be increased slightly).
This is my experience, yours may differ, I am just showing how close the tracking of the iPi Rig came to the video reference in this example.
Outcome was very reasonable and very little post processing needed to achieve this result, even with crossing and close together hands and feet movements.
Waiting on version 3 to be released, which may be easier to calibrate and align.
