Has anyone integrated a QuickCam or similar webcam into a Labwindows application?

[Ed Roberts]

I have downloaded the QuickCam SDK from Logitek, but it is written around Microsoft C++. The MS C++ program files appear to have a different structure to Labwindows.
I hope to use the USB version of the QuickCam pro.
Our application is for photon counting from an image intensifier.

Hi,

Astronomers, as far as I know, are the bunch who do the most QuickCam
development. You might try asking this question in the yahoo group
named QCUIAG (QuickCam and Unconventional Image Astronomy Group). If
you can handle correspondence in French, there's another yahoo astronomy
group which is specifically for software development. Sorry, I can't
remember the name of the gorup offhand.

Hello Ed,
If the QuickCam SDK includes C++ example code, then it will not port directly to LabWindows/CVI. However, if the code calls a C DLL then it should just be a matter of #including the QuickCam header file(s) in your CVI source code and adding an import library (such as quickcam.lib) to your CVI project. For more information, please see the "LabWindows/CVI Programmer Reference Manual" available at \manuals or online at http://www.ni.com/manuals.
If the QuickCam makes use of an ActiveX DLL, you could use the "Create ActiveX Automation Controller..." option from the Tools menu to build an ActiveX Instrument Driver. This ActiveX Instrument Driver could then be used to access the QuickCam functions. In either case, you will need a good understanding of t
he QuickCam functions (syntax and proper usage). I hope this helps to get you started.

Hi Jeremiah,

I want to caputure image from a wireless usb webcam available at 'http://www.grandtec.com/webcam.htm'

I would like to know how to interface the webcam to labview using the activeX drivers available on the cd. I dont know where are the drivers loaded on the hard drive.

Any help is appreciated. I am totally new to labview. So it would be really helpful if you provide me a step by step solution.

Thank you very much for your time.

Regards,

Mozill

Mozill,

  You will get a better response to this question if you post in the LabVIEW portion of the NI forums.  This board is devoted to LabWINDOWS.

Hi Mozill,

You will need to install the ActiveX drivers on the computer and then just use the ActiveX objects and containers in LabVIEW to make calls. More information can be found here:
