I'm using this camera and it works very well in Linux at full 640x480 x 30
fps.

In Windows I can't make it work in ARToolKit applications at more than 320x200
x 30 fps but I belive it's a windows issue. Any way I don't use ART in Windows
anymore.

I had some problems with low light environments, but haven't tryied much in
this situations. Maybe testing with other threshold values will solve it.

You can mail me if you have more specific questions.

..I hope this can help you a little.

Hey,

I use Creative Webcam Pro for some basic testing purposes with
ARToolkit2.52vrml version and it works preety good on windows 2k
environment.  Also if you want to change the size of the video frame just
remove the hardcoded 320 X 240 and make it 640 X 480 inside the code of
artoolkit and it will give you larger frame size cause creative webcam pro
supports that.  I havent used firewire camera so dont know much about it.

Nina.

I have the same problem and I would be very interested if someone knew about 
this
specific Windows problem. How come that an application will run @ 30 fps under
Linux and hardly @ 15 fps under Windows although it is the same code ??
If anyone has an idea about it, I would be thankful to hear about it.

Hi.

I'm using a modified version of AR-Toolkit 2.52 (with VRML) and the 
ARFrameGrabber-Versions of FH Hagenberg (fh-hagenberg.at) to grab my ibot 
Firewire images under Windows XP Pro.
Using the Microsoft drivers delivered only 15 fps as well. After I changed 
these drivers (by hand, because otherwise Windows always takes his own (but 
worse) drivers) I could also grab with 640x480x30fps.
Although not in every format: using RGB or some YUV-formats I could still 
only get 15 fps. The only format with 640x480x30 is YUV411.

cu,
Toby.

the windows frame-graber code that comes with artoolkit is not that optimial.
if you want better performance with any type of camera try out the 
modification by Thomas Pintaric:

bye,
Daniel

The performance problem with ARToolKit v2.52 for DirectShow (using the ARFrameGrabber)
can be traced to redundant buffering within Microsoft's SampleGrabber (CLSID_SampleGrabber)
filter. Note that, according to the MSDN DX9 documentation, the ISampleGrabber::GetCurrentSample()
method is not currently implemented, so you're forced to use buffer queues via
ISampleGrabber::GetCurrentBuffer(). The solution here is not to use ISampleGrabber at all.
Instead, switch to a more efficient filter (preferrably a renderer) that offers the same functionality.

Regards,
--Thomas
