Hi Everyone
Is it possible to acquire images from a web video-cam with Labview/Imaq.
which is connected via USB port ?

Any information would be appreciated.
Thanks in advance
Andreas

Yes, Go to INVENTeering.com and download the Activex Control that interfaces to Web Cameras, there is even a IMAQ LabVIEW example that can be down loaded.

Hello,

I wanted to update this post for those users who may be looking for a solution on using USB cameras with LabVIEW or Vision Assistant. Recently NI-IMAQ for USB Cameras was released as an example program on National Instruments' Developer Exchange (see link below). NI-IMAQ for USB Cameras is a free software driver for acquiring images from any DirectShow imaging device into LabVIEW. These devices include USB cameras, webcams, microscopes, scanners, and many consumer-grade imaging products. With the driver, users can configure their device, and acquire images into LabVIEW.

Note: While NI-IMAQ for USB Cameras comes with complete documentation, it is not supported by National Instruments' Applications Engineers. Any support questions should be directed to other users through the Discussion Forums.

hi

i only have an evaluation version of labview... Im try to learn LabVIEW now. When I would like to install the NI-IMAQ it says that i don't have the 7.1 version installed, i've got the 7.1 evaluation version... Do you really need the full version?

Lieven,

In order to install NI-IMAQ (or any of our other drivers), it does not require LabVIEW to be installed on your computer. Most of these drivers, like NI-IMAQ, also include C/C++ and Visual Basic functions if a user does not wish to take advantage of LabVIEW. In your case, my guess is you are simply having problems during the installation of NI-IMAQ when you select to install support for LabVIEW. This is an option if you select to customize the installation of NI-IMAQ.

When does the error message occur during the installation process?
What options have you selected to install for NI-IMAQ?

The driver should still allow you to install the IMAQ VIs into the vi.lib folder, so please let me know some more information and answer to the above questions and we can see if this is possible or not.

Regards,
Michael

Hello,

The NI-IMAQ for USB Cameras driver requires that you have Vision 7.1 installed.  It can not be used with Vision 7.0 for LabVIEW.  This is because of the unified application interface that was introduced with Vision 7.1 and the introduction of ActiveX controls for Vision. 

Without upgrading your Vision software, the best option is going to be for you to make functional calls to the DLLs that were installed for that camera.  That will require specific information about the functions contained within those DLLs, which can be obtained from the camera manufacturer.

Hi,
I have downloaded and installed the driver. I am using Vision 7.1 and I'm getting the error in Grab.vi example:

Error -1074396024 occurred at IMAQ USB Init.vi
  Error system.

This error code is undefined. No one has provided a description for this code, or you might have wired a number that is not an error code to the error code input

Could you help me with my problem?

Hi Dogan (how do I get that g correct?)

I think you are using a non-english (or some other languages) OS?
If so have a look at this thread

Good luck,
