I now have six PS3 Eye cameras and my VR machine has enough USB-3 ports and controllers installed to run them.<\/p>\n\n\n\n<p>Our initial setup had three or four cameras attached and used the room lighting (pretty bright, ceiling mounted LED lights) for illumination.  Initial results weren&#8217;t great but over the rest of the day we learned a few things.<\/p>\n\n\n\n<ul><li>Need a more contrasty background and a less cluttered background. The bookcases behind the area we were using were better when covered with a piece of white fabric. The tan rug on the floor was less of a problem when the model put on black socks.<\/li><li>Hands really aren&#8217;t handled by the package. No big surprise here as hands and fingers are rather small targets for these cameras.<\/li><li>More lighting is better. I added two diffused studio lights I have around and a high intensity three light halogen light bar and things became more precise.<\/li><li>A larger and more diffuse calibration target seemed to work better.<\/li><li>Sliding the calibration beacon along the floor with periodic stops seemed to work better than touching it to the floor. This makes all floor level reference spots about equal (when I was touching it down, it took a little work to make sure we had the lowest spot in each arc).<\/li><li>Aligning the reference person with the human figure in the images at the start helped quite a bit. The tool didn&#8217;t seem to do a very good job of this without manual help.<\/li><\/ul>\n\n\n\n<p>By the end of the session, we seemed to be getting a pretty good capture of arms and legs. Feet could still be a bit twitchy.<\/p>\n\n\n\n<p>Malcolm is going to look at 3D printing mounting clips to attach the PS3 Eye cameras to light stands for more stability.<\/p>\n\n\n\n<p>I ordered a couple of spare cameras to ensure that we don&#8217;t come up short if any of them fail and a couple of PCIe USB-3 cards to supplement USB controller availability. <\/p>\n\n\n\n<p>Overall things turned out pretty well and I think we learned a bit more about making motion capture without dedicated beacons work decently. The price of the package is high enough that even a short time license would need us to have some substantial amount of motion capture to get done in order to make things make sense.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Configuring Eye cameras here.
