WebCam vi?

[Jeff Shama]

All,
I'm looking for any information regarding the use of webcams with 
Labview.  I'd like to design a face recognition/motion detection type 
vi.  The sites I have found only provide sdk's for qualified developers. 
  Can anybody point me in the right direction for such information. I'm 
using Labview 7.0.


Thank you for any help you can offer.

Besides the image capturing, it has also many camera control functions and
image processing functions. It's WDM based, has many advantages over VFW
based drivers. (I think VFW is being abandoned).

Actually, I just wrote one using one of the examples Christophe Salzmann's quicktime 
interface.  Works like a dream!!!  Cross platform and handles all camera's that have a 
quicktime driver.  Contact Christophe for a copy.

Just wonder how many cameras have quicktime driver. Could you please list
some of those cameras for example?
Thank you.

Sure!

Any IIDC(I think that is the spec) compliant firewire video camera and probably a lot 
of other firewire cameras as well.  And other such cameras.  From Chris:

I am using a remote digitizer from DFG( Imaging Source?) that will function in high 
magnetic fields.   They have a quicktime driver from a third party.   Just plugged in 
the clever Labview "fat CIN" that includes code for different platforms and it works!

In short I haven't found a firewire (i-link) video camera that isn't quicktime 
compatible.  I am sure there are ones out there.  Especially the newer ones.

WDM is the device driver accessing the hardware. It is not just video capture
but all modern W2K and XP drivers are usually that. VfW is one of the APIs to 
access multimedia image acquisition hardware. I think an application does
not access a WDM driver directly but uses DirectShow or whatever Direct...
for that. As such VfW is not state of the art anymore (you could say its
use is deprecated) but a lot of WDM based video grabbers still have a VfW
wrapper and failing that there is always a DirectShow to VfW wrapper. The
advantage of VfW is its simple use and a lot of applications (including many
commercial ones) still depend on it.
That said a DirectShow access to a WDM grabber driver will usually be more
performant than through VfW.

The sad part is that under all platforms other than the "right" one,
video digitizer hardware with Quicktime drivers can be counted on one
single hand. There is a Quicktime to VfW video digitizer driver for
Windows to access VfW hardware in Quicktime but elegant would be something
else.

Re: webcam

[Irene He]

Hi Rolf,
Thank you for clarifying this, you can always make things easy
understandBut that was what I meant that IVision is Directshow based
(accessing to WDM and VFW driver) other than some other drivers are just VFW
based...but somehow I wrote it wrong :-)

Anyway, it's always very educational to read your posts.

Irene

Just to discuss availability for the "wrong" platform.  Chris' web pages gives this 
info:

* Under windows you need a proxy vdig to enable QuickTime to see VfW and WDM video 
capture devices.

* WinVDIG (v. 0.99) free ( http://www.vdig.com/WinVDIG/index.html)
* Vdig (v 1.1b1) (http://www.abstractplane.com.au/products_vdig.jsp)
the first one supports a lot of hardware 
.  I think you will find that a you 
are going to need lots of fingers on the single hand!  After the 1st hundred or so 
models (the page above doesn't mention the pixle link ones).  Why do you need the 2nd 
hundred?

I am not sure about vfw but this should give the compatibility that is "good enough".  
The "sad part" is that lack of support is considered "good enough".

In order to use USB-webcams with LabVIEW you might look here:

http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=137&HOID=50650005002D5B0100&HTHREAD=88877&UCATEGORY_0=_49_%24_6_&UCATEGORY_S=0

Re: WebCam vi?

[Enrique]

Jeff;

As DD pointed, you can look at www.biometricsview.com for information
on face recognition. In the http://www.biometricsview.com/faq.shtml";>FAQ section there
is information on integrating the Face Recognition toolkit with other
webcam toolkits for LabVIEW. Check it here:

http://www.biometricsview.com/faq_images.shtml

I know that INVENTeering also developed a motion detection routine
which you can download from their website. However, it seems that at
this time they are renovating their website www.inventeering.com, so
check out a little bit later.

QTLibrary, was: webcam

[Christophe Salzmann]

Dear list,

I guess it is time to publish the link to my QuickTime library. Due to PhD
redaction I cannot currently devote as much time as I would like for the
development of this lib. therefore I still consider it as in beta version
even if it is very stable.
This lib is meant to be a shareware, at this stage it is free for your
personal use. Currently the rule (ie licence) is that if you make money with
this lib or a derived work of this lib I would like to get my share :-)
That said please have a look at:

 http://labview.epfl.ch/qt/QTVIs.html

Sometime (often :-( ) the web server caches the wrong thing, just reload the
page to get what you expected...

As Scott said it is cross-platform, it works on MacOS9, MacOSX and windows.
It allows you to grab USB/FireWire/Parallel/Built-in video source provided
that you have drive for it. I was able to get 4 firewire cameras in parallel
(I only have 4 !) 

With this lib you can also:

- Read image from a file (or from memory) in any format supported by
QuickTime and display it in a LV Picture control
- Write a LV Picture into a file (or to memory) compressed with any format
supported by QuickTime
- Apply transformations to a LV Picture like rotate, scale, skew or any
combination of these
- Read movies in any format supported by QuickTime, this includes (MOV,
MPEG, Flash, Animated Gif, etc)
- Write movies in any format supported by QuickTime (with control over
compression) 
- Grab concurrently any video input supported by QuickTime :-) this include
FireWire, USB, built-in, etc.
- Read a sound track encoded with any QuickTime supported formats (WAV, mp3,
ACC, µLaw, etc) 
- Add a sound track to a QuickTime Movie.

You feedback is welcome but as I said I cannot devote as much time as I like
to this lib, this includes support.

Chris

Re: QTLibrary, was: webcam

[Irene He]

I want to say congratulations to Chris for his webcam
toolkit for all platform too. I feel bad that I do not
have enough knowledge of MAC and Linux to contribute
to all of the LabVIEW users since I have a similar
toolkit, but unfortunately only for Windows platform.
Anyway, happy wiring.

Re: Does Data socket support webcam?

Hi huh,

It is possible to use a webcam to acquire and save images online to
display using Datasockets.  Here is a good KnowledgeBase article (with
an example program attached!) that should be helpful:
http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/b92648089952cdd386256d0f00792187?OpenDocument";>How
to Display an Image from the Web in LabVIEW

Also, if you have our Image Acquisition (IMAQ) Toolkit and
ComponentWorks installed, Labview can be used to take the webcam
snapshots using ActiveX controls.  There is another Discussion Forum
post regarding this issue here:

If your webcam uses Firewire (IEEE 1394), more support regarding image
acquisition can be found at the following KnowledgeBase article and
the links attached:

I receive some site but they can't work. Therefore, I was wondering is
there any good program or site that can use LabView with the webcam

Re: Are there any webcam compatible VIs?

[Aaron Beitner]

Hello,

There are many third party toolkits that enable you to use webcams
within LabVIEW.  The following website gives a number of links you can
follow to find the appropriate interface for you.  One of the more
straight forward techniques is to take advantage of the options
available with ActiveX controls.  You can use the standard ActiveX
interface to call other programming environments from within LabVIEW.

http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RNAME=ViewQuestion&HOID=5065000800D399&ECategory=LabVIEW.LabVIEW+General

You will first need to have a compatible driver for the webcam
installed.  If you are using either USB or Video for Window LabVIEW
driver, a helpful discussion forum posting can be found at:

http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RNAME=ViewQuestion&HOID=50650008000F44&ECategory=LabVIEW.LabVIEW+General

It may be useful to be able to display images from the web in LabVIEW.
There is a very good knowledge base (KB 2WKG2HMV) that explains how to
grab an image file from a web address and then display the image on my
front panel in LabVIEW.  It explains how to use the Datasocket Read VI
and also includes an attached vi to convert a JPG to a picture.

I hope that this is enough to get started with.  Please let us know if
there is anything else you need.  Take care!
