Great to meet you guys at Siggraph! Please let me know what your 120 fps webcam solution your PR guy was talking about, would love to know more about this!

Hi, David
I don't know exactly what Jake (I suppose it was him) was talking with you about. We have not yet tested any 120 fps cameras with our software. I assume he mentioned Point Grey Flea camera:
http://www.ptgrey.com/products/flea3_usb3/flea3_usb3_camera.asp
It is possible that this camera can be used with our software. However, to be sure, the testing should be made. And currently we cannot afford several of these expensive cameras (about $1000 per item) just for testing purposes.

Using high-speed cameras is theoretically possible but in practice this means going to the next level of hardware costs (high-speed cams usually cost over $500 per camera), and we do not yet have any support for particular drivers for high-speed cams (like Basler or PointGrey) in iPiRecorder.

Currently we concentrate on improving the software for working with Kinects and PSEye cams. We may start working on support for faster cameras after we implement more urgent upgrades (head tracking, multiple person tracking, props tracking etc.).

I was at siggraph last year looking for a motion capture solution. Missed you this year, but at least I am using ipi now :)

Great software guys!

Hi,

In regards to Point Gray (Flea 3) USB 3.0

I was about to purchase it (4 pieces) but I wanted to verify this setup before ordering it.

My interest goes to the (1280 x 1024 at 60 FPS color sensor camera) model

Will this model (theoretically) going to work fine ?

please help, I used 2 Kinects and still I had to do some clean up and a lot of adjustments. I also had 4 PS3 cameras setup and I had
to clean up as well (for some movements)

So I am hoping for the best so far (results) by going to this product.

thanks.

Hi

If you are not satisfied with the number of tracking errors you get from 4 PS Eyes - it's better to get 2 additional PS Eyes (provided that you have the Standard edition). This should greatly reduce the number of errors.
Increased resolution practically will not give you extra accuracy over VGA cameras, but requires much more bandwidth.
Anyway, we still had not ever tested PointGrey cameras with our software, so cannot provide any guarantee.

thanks for the quick reply !

I don't know whether I should get 2 additional cameras since it bothers when going to adjust each camera to fit into the right angel, its a little hassle.
eventually there will be Kinect 2 once the xbox720 gets released and we will move away from the low Res. 640x480
High Res. will be more attractive and tracking specific parts of the body (I believe) will require intense tracking and accuracy, so the Low Res. will not yield good results (This is completely my own opinion)
so either way, now or later HD res. is the current standard and sony just released 4K TV following Samsung soon as well.. why not we jump now
in using High Res. (HD) cameras since they are available, they are expensive but will live longer for the upcoming technologies (face tracking, expressions, etc.) all at once.

I first started doing small animations then I dropped it (discontinued the project) since I was cleaning most of the time my animations, then I decided to switch back doing my animations manually (short and simplified) but I can't continue like this, I will need to hire someone or 2 to go further with the project, so I returned back to ipisoft and looked around for any USB 3.0 HD cameras and came across PointGrey products.

if I managed to connect all 4 cameras will I be able to sync them together (theoretically speaking) ? HD Res. @ 60 fps?
( I will verify with PointGrey as well)

(1)My system spec is high (i7 extreme - 6 cores) overclocked to 4.0ghz
24 GB RAM
WIN 7 Pro
SSD HD
SAPPHIRE HD 7970 6GB Vapor-X
USB 3.0 slots

(2)another system (i7 extreme - 6 cores - overclocked to 4.5ghz with water cooling), 32 GB RAM, win 7 Pro, MSI Lighting GTX 580 (3GB)
MANY USB 3.0 slots

thanks.

Hi,

I managed to get a response from the PointGrey support team.

"We have not tested this software so far but our cameras support DirectShow and if this software is using DirectShow also, I do not expect an issue using our cameras with this software."

so it should work fine.

Did you guys try High Res. + 60fps in your testing for motion capture or not so far ?

thanks.

No, we did not try more than VGA resolution yet.
As PointGrey camera has DirectShow drivers, it should be supported by iPi Recorder. However, some DirectShow cameras produce weird errors with iPi Recorder, so there is still a chance for issues. If not done, I recommend to accertain from PointGrey whether multiple cameras attached to a single PC work fine.
Also, be aware that with highres video modes the data bandwidth increases significantly - you may get stuck with USB controllers, or disk speed, or CPU performance for compression.

Hi

sadly here is the response from the Point Grey support team,

"We tested the Flea3-USB3 camera (and also one of our FireWire cameras) with the trial version of IPI software and the recorder. Unfortunately the software is not able to stream from the cameras (They are recognized as Point Grey Cameras but the software gives information that the camera is not able to stream.)

It looks like our cameras do not work with this software. "

:(
