Thread Subject: AVT cameras

Hi,
I gonna buy an AVT camera and I was wondering if anyone is
using this type of camera in order to let me know how it
works in matlab.
Basically, what I'd want to know is: anyone has experience
with AVT cameras? Which data stream can you get in real time
acquisition?
Thanks in advance for your replies.

Regards.

I am working right now on a project using an AVT Guppy camera with a
Firewire interface. The only problem we had is before we tried using
the camera in MATLAB (using the Image Acquisition Toolbox) someone had
installed the AVT software. As a result, we could not get the camera to
work at all with the CMU driver that MathWorks recommends for
compatibility testing. As soon as I uninstalled the AVT software all
was well and the camera works fine with MATLAB. So, don't install
anything from AVT, just plug the camera in and use it.

I don't understand what you mean by "which data stream can you get...".

I am trying to use an AVT guppy camera with Matlab 7.2.0.232. I was initially using the AVT firepackage software, but have since deleted it. I then installed the CMU driver and software, but the camera is not recognized by the CMU software. I have tried to update the driver by going into the device manager, but there are no imaging devices listed on my machine. Do you have an idea how to fix this problem? Thank you

There are some different driver packages available from AVT:

- The FirePackage (always recommended): This replaces the 1394 interface card driver, causing the CMU diiver (and the other drivers from AVT) to fail. If you have installed that one you should use the "Install or remove 1394 driver" utility, uncheck all interfaces, enable the "install MS driver for others" box BEFORE installing the CMU driver. At this moment the FirePackage can't be used with Matlab imaq

- The ActiveFirePackage / DirectfirePackage are DirectShow (or 'winvideo') compatible drivers. With the ActiveFirePackage you'll get some trouble with multi camera applications, but on the other hand it is the best choice if you are using the interlaced Guppy cameras. If DirectShow and multicamera is interesting you should use the DirectFirePackage - the only problem here is that there is no 1394b support.

- 1394b support: You know that if you want to use 1394b cameras you have to replace the 1394 interface card driver: That one coming with XP SP1 is working. There is also one from AVT [working with AVT cameras only!] that can be used with XP and Vista.
