hello,
did anyone used a fast camera (100 or 200 fps @ 640x480 or more, with good video quality) with pd/Gem?
i'd like to have information about the camera and protocol how to do this.
thanks Cyrille
I've heard good things about this one, plus it goes up to 120fps:

hello, thanks for your answer. but the ps eyes is not what i'm looking for. i mean : it's a good webcam, specially for it's price. but at 120fps, the image size is "only" 320x240, and it can be very crappy if you don't have lot's of light.

I thought you used one for the juggling project a few years ago? It worked using ethernet and you had to make a movie for Quicktime to load to grab the stream.

Hi Cyrille, you might wanna try something from http://www.prosilica.com/products.html
Some models go up to 200fps and still fulfill your resolution requirements, plus i know Sébastien Roy here at UdM uses them under Ubuntu. Haven't played with them myself though.
Cheers,

From what i know, he uses them in real time but i don't have info on the
details on how he does it. I'm pretty sure he doesn't use GEM though. PD yes, GEM no.
I've CCd him, he might be able to tell you more.

Yeah... I understood. I had heard of that joke over a decade before I finally watched Spinal Tap.
But I was trying to make another joke on top of it.

well, this was on osX, so it was not on my computer. i'm using only linux... but, quicktime add few sec of latency, so it was not usable in RT. we used it only for none realtime stuf + a DV cam for real time.

You might find that to be the case with most high speed cameras. Above a certain rate they are intended for slow motion playback later and not real time use. Cameras that record hundreds or even thousands of frames per second use special RAM on the camera to store a few seconds and then download the frames using network or USB connections.

later and not real time use. Cameras that record hundreds or even
thousands of frames per second use special RAM on the camera to
store a few seconds and then download the frames using network or
USB connections.
If its for tracking applications, any of the video tracking
installations that I have been involved in have used Black&White
security cameras with a visible light filter. Those cameras are
analog and about 150-300€. Then you need to get a analog capture card
though. That could be a Canopus or anything that provides low noise
and high framerate.

i've also done this a lot. it's not what i'm looking for.

i never heard about analog camera doing more than 50i. an analog security camera is not a high speed camera.

I used a IEEE 1394 point grey flea2 some month ago, on os X, wondows
and linux, but with linux I had difficulty to make it work and in
particular with pd (I don't remember exactly as I also tried ps3 and
others and several other things including acquisition with openCV true
some externals that I made). On os X it was working natively for sure
(try quicktime I suppose ...), on windows with a special driver. I
must say that as I'm not a pure linux guy, so I maybe missed something.
I used also another one quit similar from another brand, but more
expensive, with additional optic (I still try to remember her name...)
I just see that point grey has new products, maybe you should have a
look.

From Point Grey, there is the Grasshopper model :
http://www.ptgrey.com/products/grasshopper/index.asp The version GRAS-03K2M/C works at 640x480 and 200 fps. Is there any delay ? I don't know. About Linux support : http://www.ptgrey.com/support/kb/index.asp?a=4&q=17 ++

there is good database for that kind of cameras here ::
The IEEE1394 Digital Camera List
http://damien.douxchamps.net/ieee1394/cameras/search/
ya ... under linux they are suposed to work all under libdc1394
http://damien.douxchamps.net/ieee1394/libdc1394/
coriander is nice control software using lindc1394
http://sourceforge.net/projects/coriander/
also there is unicap, an API that supports dc's
(http://www.unicap-imaging.org/)
is Gem0.92 able to use unicap?
i'm not sure but if it's dc's should work... i never test it ...
me and yves write a very basic implementation of pdp_dc1394 but
atually it only works with unibrain monochrome cameras ...

you wrote it, me, i was at the coffee shop.. then i integrated in pidip ... but hidden...
but yeh, it's optional in svn/PiDiP if you install libdc1394 and do a ./configure, it should compile and you can try it ( as announced, very experimental and only monochrome )....
but pd-extended doesn't use autotools, so you can only try it if you compile pidip yourself ... ( hihi, sorry this reminds me of another thread )..
