Capture images in labview using wireless webcam (D-Link DCS-1000W)

[km76107]

I would like to capture images using a wireless webcam into my labview screen. I am using a D-Link DCS-1000W 802.11b Wireless Webcam. Are there any example VIs or solutions on how to implement image acquisition using a wireless webcam into a labview screen? Any help is appreciated.
Thanks in advance.

We don't have any drivers that will actually be able to interface with your D-Link camera and bring the image across. Our IMAQ driver interfaces with our NI framegrabber boards and our IMAQ for IEEE-1394 driver will interface with firewire boards. My guess is that with your camera you have the means of acquiring those images already, though. Are they stored somewhere on your computer in a temporary folder after their wireless transmission? The way you'd want to bring that across to LabVIEW would be to open up those image(s) and display them in one of our Image Display controls on the front panel of a VI. For an example of how to do this with LabVIEW and the IMAQ VI's, go to http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3EB4556A4E034
080020E74861&p_node=DZ52506 and download the code.

Hopefully this is helpful to you in getting things squared away.

If you can use your camera as a webcam the same way you can use a regular webcam (Logitech, for example), then probably any of the VFW VI's libraries available will do it. Check the followings:

LabVIEW webcam library by Peter Parente

IVision LabVIEW Toolkit by HYtek Automation.

INVENTvisionVFW by Inventeering (contact them - website under remodelation)

LabVIEW drivers for the Logitech QuickCam by Christopher Relf (available via Info-LabVIEW.com. File is Logitech QuickCam LabVIEW Driver v1.0.zip)

Hi Jim,

Thanks for the prompt response. Do you have drivers for wireless webcams other than D-Link? My application is to just demonstrate video capabilities and i think IMAQ or NI-VISION might be an overkill.

Hi Kmoorthy,
The dlink people should have given you a driver and viewer software,so why dont you call this from labview as in the case of any other USB port web camera,exapmles for which are avialable on the net in NI.com.

Hi Vicky

Thanks for the response. Where do I find the examples in NI.com that call image file from USB port?

Thanks

Sorry to be the bearer of bad news. We just don't have a driver for the wireless webcams. That may be something down the road, but we're not there now.

Sorry for any inconvenience,
Jim

Hello,

The following link explains how to view an image array in a LabVIEW picture control. It also includes an example VI which does this.

Let me know if this does not help.

How i can see real time view from webcam (D-link DCS-1000W)at lookout 5.0 ? is there any drivers? activeX?

prantajaya,

Lookout does not natively support displaying moving video. There is an animation object, but I don't think this will work in your situation because it requires a static BMP image to display.

I looked through some of the documentation related to your camera and it appears to include ActiveX drivers. Once you install these drivers on your computer you should be able to load them into Lookout.

Unfortunately Lookout does not support ActiveX methods or events so if the driver for your camera requires the use of these you will not be able to use the control. Refer to the D-Link documentation for instructions on how to use that particular ActiveX control.
