I picked up all of my PSEyes from Game/Gamestation stores here in the UK for £1 each

Is there any way to use 2 kinect with PS3 cams? Imagin 8 PS3 cams + 2 Kinect

Mixed depth+color configurations are not supported yet.

...

This is an old post... So

Now that the Kinect X Box One is in use, they are showing great results with iPi, even if using only a single sensor, but of course dual sensors are better for optimal tracking results, although 2 computers are required using distributed recording. (Each additional sensor requires its own computer).

Still, single or dual sensors is an easier set up then 6 - PS Eyes, especially for room constraints and special requirements, or if have to break down after each recording session, or need easier mobility, but always comes down to what types of actions you need to record and how much you want to spend, but the need for extra computer(s) to run dual, or more Kinect v2 kind of kicks cost in the rear anyway, as not just any low budget desktop, or laptop will run a Kinect v2.

...

For starters. I'd recommend depth sensors/Kinects. It's easy to set up & calibrate!

For those seeking high-quality motion capture. Playstation eye is a way to go! It lets you track fast motions. Such as fighting, energetic dancing & more!

Here is a one-month-old content that I found on Tech Radar hoping that it can help you decide which one to get.

I loked at this test with 10 PS3 Eye camera and I see it still jumps a little

Once my intention is to reduce the need of retouch, I'm back to the question...

If I use 6 Hi Res Cameras like Go Pro at 720p 60 Fps, instead of 6 PS Eye ( only 320 pixels ) will the bigger resolution give me more accurated result? Or it does not matter?

For me, it's not a problem if the computer takes the entire night to process, I need fine motion without jumps.

So, the question is... Does ipisoft computes high resolution images inside? Or does it have a limit? Does hi res images really give more precision?

Would a black cloth ( gym knitwear ) with some white line skeleton drawn on it help the optical processing?

What should I do to get the maximum quality capture?

Hello,
higher resolution gives some benefit, but it is rather minor.
This is because the algorithm matches the whole model to video. So resolution becomes benefitial only in case of very big capture area (when actor is 7+ meters from camera).
If you do not plan to use such big room for capture, Sony PS3 Eye with VGA resolution will give you the same result in terms of quality.
It is more important to have ambient lighting and good color contrast between actor clothes and background. Also use different colors for pants, shoes, torso, sleeves.

No. The way the software works is that it looks for whole a human figure in the footage to constructs a 3D human form it can track with. Details like a 'skeleton' drawn over the clothing would just confuse the shape the program is looking for.

For RGB video capture, it's best to have solid colors. For the upper torso, a red or green long sleeved shirt with a black t-shirt pulled over works well. This helps the software separate the arms from the torso, and the black shirt 'hides' shadows cast by the arms. Dark pants for the legs (doesn't have to be black, just a dark color,) and dark shoes. No need for gloves on your hands. Avoid glossy, reflective surfaces in the clothing or the background.

Bear in mind that you need contrast with the background, so pick colors that don't blend with the background. Mocap Studio will attempt to subtract the background but why make it harder for the software?

BTW, the above is another reason why I currently prefer depth sensor recording.

With a depth sensor, color does not matter, only the shape. In this case, close-fitting clothing is all I need. With Kinect, larger shoes seem to help with feet tracking, so I usually wear boots. That's pretty much it. This is one of those convenience factors with depth sensors that I mentioned in the other thread.

Actually, with depth sensors, certain colors or surfaces can matter. Generally speaking, you want to avoid solid/flat black because it can absorb the IR rays instead of bouncing them back to the sensor. You also want to avoid glossy reflective surfaces, which might reflect too much room light. This seems more of an issue with older sensors than Kinect 2 but, again, why make it more difficult?

The trade-off is that it's not as accurate as PS3 Eye but it still works pretty well and it's easier to use in a small space. On my personal and freelance projects, I'm usually working solo, so I try to keep things simpler where I can.

Hope this helps.
