Acquire image from USB webcam

Hey everyone.  I have a Logitech USB webcam that I would like to use to acquire still images.  I am using LV 8.2.  All the posts I have read suggest using NI-IMAQ for USB Cameras.  I have tried to install it, but it says "You must have Vision 7.1 or higher with LabVIEW 7.0 or higher, or you must have Vision Assistant 7.1 or higher installed to use this add-on."  I don't have Vision or Vision Assistant.  Am I doing something wrong?  None of the other posts seemed to mention that you needed Vision in order to use the add-on.  Does anyone know how I can acquire images from my USB webcam through LV 8.2 without having to buy additional software?  Thanks!

This question comes up often. That driver is something that NI provides as a convenience, and yes it requires additional software, as stated on the description for it. As for alternatives, did you get any software with the camera that looks like it could be used with LabVIEW, like an ActiveX library? That can certainly be used. As mentioned in this thread, supposedly RoboLab for LabVIEW has some tools, but I've never used it myself. You can also try the LabVIEW Webcam Library. Kind of old, though.

  • Converting a snapped image from usb webcam to rgb model color

    Hellow everyone,
    I am trying to convert  a snapped image using usb webcam to RGB model. I have two VIs, for snapping and the other for converting JPEG to RGB as the attached VIs bellow. My problem is how to connect these two VIs in one VI to make direct conversion from snapping to RGB model. I am using LABVIEW 8.6
    Attachments:
    NI-IMAQ for USB Snap LV 86.vi ‏43 KB
    GetRGB_LV71.vi ‏30 KB

    So the two VIs that you have are not directly compatible with each other. Notice that the first one uses IMAQ VIs (an add-on), while the second is using VIs from NI's Base Package. This means that the first VI (the snap) outputs an "Image" type, while the second VI is using an "imagedata" type.
    To clarify, you want the histogram of each color in the image, is that right? This is what a histogram is:
    http://zone.ni.com/reference/en-XX/help/372916J-01/nivisionconcepts/histogram/
    If so, you can use the IMAQ ExtractColorPlanes VI to extract each individual color plane...
    http://zone.ni.com/reference/en-XX/help/370281M-01/imaqvision/imaq_extractcolorplanes/ 
    ...and then you can use the IMAQ Histogram VI to map the histogram of that color plane.

  • Capturing data from usb webcam

    I'm interested in the acquisition of footage from a usb webcam into labVIEW. I have the professional development system and downloaded NI-IMAQ which I believe i'll need from reading online material.
    I don't really know where to start to link the camera with labview so any material would be a great help...
    Final question, is it a big undertaking acquiring data from a video camera in labVIEW? it's just i've limited time to work on a project and want to know if it's worthwhile undertaking or if it will be very time heavy. I've a few months labVIEW development experience if that would give an indication to anyone...

    Hi,
    First your USB Cam needs to be DirectShow Compliant.
    Then you will need NI-IMAQdx from the Vision Acquisition Software 2009 (supports LV 8.2 and higher) or higher to acquire images from USB cameras. The NI IMAQ driver is to capture images from framegrabbers, and the NI SmartCamera, not for USB. There is also a own IMAQ USB Library for the Vision Acquisition 8.6 but since you need to buy the Acquisition Software I would recommend to use 2009 or higher where we added the DirectShow Support to IMAQdx.
    The Vision Acquisition Software is just for image acquisition and processing. If you want to do image processing you will need the Vision Development Module.
    And when doing a search at ni.com you should find some articles, examples and tutorials too.
    I can't estimate how much time you will need get that running, but you could just try to run one of the examples for IMAQdx in LabVIEW and then see how it works.

    This seems a very popular question coming up about once every week at
    least. And there are many good answers in the developer Zone on www.ni.com
    Check out:
    Irene He's IVision Toolkit:
    http://www.hytekautomation.com/Products/IVision.html
    or
    Pete Parentes WebCam library:
    http://www.cs.unc.edu/~parente/labview/index.shtml
    The first is a rather impressive Video Manipulation library with a
    nice video capture interface to VfW too, and the second is a simple
    video capture library to access any VfW compliant device.

  • 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.

  • Get an image from USB cam without NI VIsion Acquisition

    HI
    I am looking for a way to capture images from USB cam without using a paid library ImaxDx for Labview.
    Have you any ideas?

    Hello MaxEngee
    Off hand, I suppose you could run the third party capture software in the background and have a LabVIEW scan the target directy for changes/new images and import the image as necessary.
    In the mean time, if you install the NI Vision Acquisition Software, you do have a 30-day trial period so perhaps you may consider exploring the environment to see if it is right for you.

  • HELP Acquire sound from a webcam

    Please help (it's really important !!!)
    We need to know how to acquire sound from a webcam with Labview 6.1
    Thank you (and sorry for our english...)

    Hello
    As Benjamin said, some more info will help to understand your problem.
    In the meanwhile, you can try the next modifications:
    Using a sound recordig example  from labview, in the "Si config" change the "device ID" 0 ( sound card) for 1,2,3.... until you get the sound from the webcam mic. This should help if the webcam driver installs, too ,the mic driver as anothe windows sound device.
    Hope it helps

  • How to acquire image from S-video camera

    Hi,
    I have a camera with S-video interface. I use a S-video to USB adaptor to acquire the images from my camera. Popular video editor/maker softwares, for example Windows Movie Maker, ULead VideoStudio, etc.. are able to display the video capture from my camera (using the same S-video to USB adaptor). Thus, I think the adaptor transferred the camera to an USB Directshow camera already? However I cannot grab images/video using Labview. I have installed IMAQdx, and I can use the same LabView VI to grab images/video from my USB camera.
    Is there any suggestion for my case?
    Thanks.

    Make sure you are using the right color channel, in most cases YYUV will not display.  Use RGB.  Also try changing the resolution settings.

  • How to capture image from USB camera in Labview 2010

    Hey all,
    I am very new to Labview but am working on a project that requires me to use a sensor to send a signal to Labview to capture an image from a USB camera and save.  Then apply some image processing to do some geometric calculations.  The calculation will be based on pixels so I guess the image needs to be in bitmap form.  Right now I am just trying to start with the image acquisition part and was wondering if this can be done in Labview 2010.  I have the vision toolbox and NXT Robotics.  Are there any examples on this website that will help and do I have te proper tools to do this?  Once I get the image capture/grab to work using labview, then I could work getting a sensor signal to trigger that capture and finally the processing side. 
    Like I said, I am very new to this so I am not sure if I need to download any particular drivers or vi's that I am missing or what those might be.  Can someone provide some insight, links, or any help would be appreciated.
    Thanks in advance for any help/suggestions.

    Hi wklove,
    In order to do vision with LabVIEW you need to to have the Vision development module and have NI Vision Acquisition Software (VAS) installed. It sounds like you are missing VAS you can download it here. Once you have this installed you should be able to see your camera in Measurement and Automation (MAX). After you are able to see the camera, take a look at the NI Example Finder by going to Help » Find Examples

  • What software do i need to acquire image from a camera and 1407 board

    I need to acquire an image and measure thickness of a needle. I have labview 6.0.2 and have installed NI-IMAQ 2.5.1. What other software do i need to install? Do i need Advanced IMAQ Vision?

    With NI-IMAQ (now up to version 2.6) you are able to acquire, display, and save images. With IMAQ Vision, you'll be able to very accurately measure the thickness of the needle. If you attach an image to this post, I should be able to tell you just how accurate IMAQ Vison can be. You can find out more about IMAQ Vision (which is a component of the Vision Development Module for LabVIEW) here, http://sine.ni.com/apps/we/nioc.vp?cid=2881〈=US
    The other route (aka, the free one) is to convert the image into a 2D array of pixel values. From this array, you may be able to measure the thickness of the needed by writing your own algorithm. It most likely won't be as precise as the IMAQ Vision tools (which give you real world measurements down to the 0.1 pixels).
    The Vision Development Module will work with LabVIEW 6i, so there is no requirement to upgrade to LabVIEW 7 Express. But in case you're curious, the new LabVIEW is really something. www.ni.com/labview is the place for more info.

    Or if you don't want to repartition your USB drive, just use dd to create a large file big enough to hold your image and format that as ext3 and mount it, move your image into it and have fun.
