Webcam labview
Hi!
I wanna do a live streaming of a webcam with LabView. I've been told to use NI-IMAQ but...the only one I found requires a Vision Assistant 7.1... so my qestions are:
1. Can I find a FREE (not a trial) IVISION with the minimum requirements to help me?
2. Can I find a LabView with the IVision included? (I have a LabView 8.0)
3. If I can't afford a IVision...can I still fisnish the project with the webcam?
4. Who can Send me an exemple of a project like that???
Thank you!
Solved!

Hi snuk,
To use a webcam with LabVIEW, you will need the IMAQ for USB Cameras driver, which has the following requirements:
- Windows Microsoft Windows Vista/Vista x64/XP/2000 (English, Italian,
Japanese, French, Italian, Norwegian, Dutch, Spanish/Portuguese,
Russian, or simple Chinese).
- LabVIEW 7.0 or later.
- Vision Development Module 7.1 or later
- NI Vision Acquisition Software 7.1 or later, for USB LabVIEW support.
- Vision Assistant 7.1 or later, for USB Vision Assistant plug-in module support.
- Vision Assistant 8.0 or later, for USB Express VI support.
There are examples on the NI DeveloperZone Community, but you will need the above requirements to run the examples. Here is a link to one of the examples:
NI-IMAQ for USB: Grab and Save Image with USB Camera
I hope this helps!

A Google search on "webcam +labview" will probably return other pages.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences. -
Could anyone help me, please?
I've download LabVIEW webcam library from Peter Parente'Homepage
http://www.cs.unc.edu/~parente/labview/webcam1.4.zip
I use my webcam to capture indicator display screen but the charactor that i get is reverse (like look in the mirror)
Could anyone suggest me how to solve this problem? Is there any VI to flip the image and can use with Peter's Libray? I use LabVIEW 6i,sir
Thank you very much

1.- If you have IMAQ vision 7.1, download USB IMAQ driver fron this web and will have no such problems.
2.- If not, convert your image to a 2D array an see attached picture about how to revert image.If it does not run for you, try transpose 2d arrrays.
Hope it helps

I want to interface third party/NI Webcam with Labview .
In my application i want to interface 3 NI / Third party WEBCAMS on TCP/IP with Labview 8.6 on host PC having Windows XP OS.
I am using Compact CRIO 9704 hardware with real time deployment module.
For interfacing webcams which drivers i required? OR Any deployment module is available in NI?
Please suggest.
Thanks in Advance.
SachinHi Sachin,
These cameras will be interfaced throught ethernet or USB. Will they be connected to the PC running Win XP or are you looking to interface them with the cRIO. -
How to detect baby crying using labview and webcam?
Hi, I am new to labVIEW. I have a project that it requires me to develope a application to detect various types of baby crying using labVIEW.The hardware we use will be webcam or kinect xbox 360. The system for my computer is windows 7. I used to try to create a threshold frequency to detect baby crying,but it not work well. So I want to ask what else method should I use to develop this application that can differentiate baby crying with other kind of sound( like normal talk, music...) correctly? As I just start learning labVIEW, hope the method to be easy to understand. Thanks.
This is not really a LabVIEW question, but a signal processing question. Do you have a set of crying sounds in order to be able to calibrate whatever algorthm you are trying to implement?

How to run 2 same webcam models in labview.
hello everyone,
i was wondering that how can i run 2 same webcam models at the same time. Well i have been able to run 2 different webcam models at the sametime in the same VI but it gets confused when i try to use the same models. It takes the images from the same camera even when i try to display the other camera. I used a VI that gives the hardware ID of the interfaced cameras as same webcam models will have different Hardware ID. But still it gets confused. Is there any one who is working or who had worked on the same lines. Please help me . Is there any other library that can be useful or any other software interfaced with labview. I would like to keep the option of modifying the current webcam library as the last option.
Thanking you.
Royal Tiger.This is a known issue with the driver that occurs when two of the same type of camera exist on the system. Because the driver uses serial number information stored on the camera to distinguish between cameras, cameras of the same type will appear to be identical to the driver. Also, because the USB driver is not supported and provided for free in an "as is" state, there are no current work arounds for this issue, and no development at this time on a bug fix.

Labview with Mindstorm ; Labview with Webcam
I use Win 2000 and Labview 6.0.2. an I have 2 Questions
1.Is there a vi to control the LEGO-MINDSTORM directly.
2.I need also a vi to get a picture from my USP Webcam to handel it with
e.g.IMAQ
Thanks
wolfgang koren
[email protected]There are two basic ways to use the LEGO RCX with LabVIEW:
1. The LEGO Mindstorms software that you buy in toy stores will install an Active-X component called spirit.ocx which you can then use in LabVIEW. LEGO released an SDK with documentation on how to use this Active-X component:
http://www.legomindstorms.com/sdk/
2. ROBOLAB is a LEGO Dacta software package that you can buy from catalogs (not in toy stores). It is actually a stripped-down version of LV5.1 with a set of VIs that can communicate with the RCX (without Active-X so it is cross-platform). Its possible, if you're tricky, to copy all these VIs into a full-version of LV5.1. For info on ROBOLAB, check out:

Acquire Images from webcam in LabVIEW 8.5
I've been working with Labview for week now and have done several
online tutorials and things like that. I need to be able to record an
image from a webcam into Labview. I've found numerous discussions on
the topic but none that contain any solid examples. I have Labview 8.5
with the NI-IMAQ drivers and NI Vision.
What
are the basic steps that need to be done to aquire an image from a
webcam and display it on a front panel? Any example VI's or detailed
descriptions would be more than welcome. Please understand that I have
just started working with LabView so some concepts like device drivers
are still a little new to me. Thank you for any help you can provide.Hi CanadianKyle,
I've been working with Labview for few months now and have done several online tutorials and things like that.
but i can not tell you exactly that Vision requirement is must or not?......
But I Think there is no other way to use this without Vision 7.1 or Higher.
U will get Vision with evaluation version on Ni.com.
You can try for this, It will help you.
best luck. -
Vision Acquisition of webcam on LabView
Hi, I'm using NI LabView 2009 with Windows 7 as my OS. I have a simple question, I just want the vision acquired from my webcam on the LabView. I googled piles of codes and they all show that there used to be an USB webcam version of icons which I believe they are not used in LabView 2009 anymore. Will you show me the block diagram?
Hi Ray Lim,
You can take a look IMAQ for USB for labVIEW 8.6 in this link:
http://zone.ni.com/devzone/cda/epd/p/id/5030
To use them in labVIEW 2009, you can use the upgrade IMAQ for USB to labVIEW 2009 utility in this link:
https://decibel.ni.com/content/docs/DOC-10622
I hope that this helps and don't forget to kudo if it is.

Dear forum members
I'd like to design a user interface which shows a live video and capture still images for it by a DirectX compatible USB webcam using LabView or NI Vision Toolkit, how can I do this ? and If this is possible How can I reach the webcam DirectX filter properties and set them using LabView ? I would be grateful to anyone Who lead me to the correct solution.
Sincerely
Cem DEMiRKIRCem,
With our example programs you can acquire and save an image (IMAQ >> File Input and Output >> Snap and Save to File.vi) from one camera, if you double the VI's to create the image and the image task, you can easily have one program acquire and save for two cameras.
I may need more information on what you mean by calibration. Do you mean basic camera setup? That can be done in Measurement and Automation Explorer by setting up the options within the IMAQ settings for each camera. Or do you mean more complex calibration for special types of images? The more description of what you mean, the better I will be able to help you get it done. You mentioned zoom and motion parameters, what kind of motion? Our vision drivers only control triggering the camera to acquire, then analyzing, processing and displaying the resulting image.
If you have more details on exactly what you want to do, that would be great. Let me know if you have more questions, thanks!

Please I want to make a snapshot from a driverless usb webcam in Labview 2011. I can do that easily using Matlab. Any help.
Please post in the LabVIEW forums rather than the version conversion board.

Hello all,
I need to interface webcam with labview 2011,
My requirement is as follows,
1. Capture the image read by webcam using labview.
2. Store it in local harddisk
3. Compare it with standard image stored in PC and decide whether read image is OK or not.
I am completely new to IMAQ and went through forum also. Can you tell me what are the steps to do this, how to getting started. What software I need to install for this,link and which webcam is good for this.
Thanks
Kudos are always welcome if you got solution to some extent.
I need my difficulties because they are necessary to enjoy my success.
--Ranjeet1. If you are using a webcam, ensure that the camera is compatible with DirectShow, and that the camera driver is installed and functioning.
2. You will need to install the Vision Acquisition Software. The software features the activation-based NI-IMAQdx driver for acquiring from DirectShow-compliant devices. A license for this software is included with all NI vision hardware and all NI vision software licenses, and is also sold separately for applications that do not require image processing or specialized hardware.
3. I am not sure how you are 'comparing' the acquired image with the image that is stored in the harddisk. But, if you want do machine vision & image processing, then you will need the Vision Development Module. In general, VDM functions are to be used for post processing images. Some example functions are: pattern matching, particle analysis, edge detection, thresholding, histograms, and optical character recognition. This module includes the VAS that was described earlier.
4. There are lots of examples that are shipped with the software to help you understand and achieve what you are trying to do.
Here is a good article that describes the different vision software provided by NI:

What support is there for a USB Webcam in Labview, and on what platforms?
I need to acquire a real-time image from a USB webcam for a remote control program I am building. It has to be USB as it needs to work on many computers without worrying about video data acquiring PCI cards and the like. I would like it to run on Windows 2000 ideally. Any ideas?
Check the following answer by Jim Kring. Also check previous posting from him, as he has been succesful using Video For Windows in LabVIEW.

Bonjour à tous,
Les liens qui pointaient pour les vi NI DAQ pour me semnblent fermés...
Où peut on charger ces vi qui gèrent les caméras USB pour LV 2013 ?
Merci
CordialementBonjour,
SI j'ai bine compris, vous avez une version 2013 de LabVIEW et vous n'avez pas les fonctions Vision permettant de faire de l'acquisition d'aimges avec votre webcam et vous avez récupéré un programme dans une ancienne version qui les avait mais du coup qui est brisé.
Il vous faut installer le module NI Vision avec les drivers Vision pour avoir accès à ces fonctions. Reste à voir si vous possédez ce module.
Cordialement.

Acquisition video avec webcam sous labview
Bonjour
Je souhaite avec Labview réaliser un essai (acquisition analogique) et filmer l'essai en même temps (acquisition video par webcam USB)
Ensuite lors de l'affichage des résultats sur graphe, je veux pouvoir afficher l'image correspondant à l'instant désigné par le curseur
et donc lier le visuel à la valeur mesurée.
Je ne souhaite pas utiliser IMAQ et matériel adapté pour cause de budget.
De plus, dernière contrainte il faudrait une vitesse d'acquisition relativement élevée (jusqu'à 90 FPS).
Sinon quel est le maximum de FPS que je peux atteindre?
Si quelqu'un peut me conseiller merci d'avanceSalut
Pour une appliquation de ce type je te conseillerai d'utiliser les drivers videoocx (http://www.videoocx.de/index.htm?/sourcecap.htm) Il s'agit en fait d'un contrôle activX qui te permet de récupérer tes images de ton appareil USB (webcam, grabshow...). Ensuite par utilisation de noeud de propriété et de méthode tu peiux contôler ton acquisition vidéo, ton extraction d'images....Par contre pour les débits faut te renseigner sur le site.
