USB webcam

HY all. I'm beginning to realized the complexity is labview... I am new to programming in labview so I need your help... I'm trying to make a program that allows you to capture an image of my USB webcam, but I don't know very well and the driver problem is worse! I had already read this topic avicap32.dll. I preferred a project to do, I need someone to help me?

I need UN program who can see my USB webcam with a botton that allows you to capture an image, something that learn the path to registration photo (I don't know what is called... something that I can give the path to the folder of the United Nations and stay like that)...

Hope that's not big thing to ask and I can help me! Nice day!

Thanks for trying to help me. So, on the http://forums.ni.com/t5/LabVIEW/2-hours-finished-the-webcam-program/m-p/906890/highlight/true#M40866... works for me, but only in Labview 8.5 or more...

I have download some webcam programs of this forum, and I save 9.0 8.2... It seems that it works for me: he sees the camera, but when I want the snapshot image, it gives me this error:

"1172 error to the calling method error NULL ObjectId System.Windows.Forms.IDataObject.GetData (System.ArgumentNullException: Key cannot be null.).
Parameter name: key
) in webcam_fernando_saveas.vi
Possible reasons:

    Hi poslive

    To provide you with useful suggestions for workarounds, it s essential to know some more details:
    (1) what laptop have you and what system is preinstalled on this laptop?
    (2) have you installed Windows own system or use the default image factory preinstalled by Toshiba?

    You should also check if the webcam is recognized in device properly Manager.

  • Satellite A660: how to record videos with USB webcam?

    I recently bought a Satellite A660, which has a built-in webcam. Using the Toshiba provided video application I can record videos, but I find the clarity and brightness of the rather poor image, even in good lighting.

    I have a USB webcam that I plugged in and tested for example in Skype, and he produces images much better under the same conditions. My question is: How can I know Toshiba video application to use instead of the built-in USB webcam? I can't find any settings where I can choose which camera to use.

    If this is not possible, do I need to install other video recording software? Windows 7 does not have all the applications where you can simply record a video from a webcam (I thought Windows Move Maker to do that, but apparently not).

    I just want to be able to record videos of my USB webcam - any suggestions on the best way to proceed would be welcome.

    Thank you

    Put I don't think something like this is possible. Pre-installed Camera Assistant Software is obviously designed to work with the built in cam only.
    What you need is a third party software that you can use for this application.

    Google around a bit and visit a few video forums where you can pick up some info on it.

    A project I want to do is write a Labview application that would communicate to the Webcam USB and publication of the application in a secure web page, and allowing users to control Labview applications at home, work, and anywhere in the world without having installed on the PC of the Labview software. On the web, users can control the Labview front panel for zoom, annotations, etc. As a surveillance camera the USB Webcam will be detect an object moving, save images when motion was detected, an alarm to alert.

    I was wondering if anyone can help me with this.

    I have Labview Vision and I can get the USB Webcam streaming images.

    I don't know where to find information about the detection of a moving object.

    Can someone help me on this please?

    Hi krispiekream!

    I guess that your USB camera has the ability to zoom through a control programmatically? If not you should be able to control the camera using a remote facades, which require the LabVIEW runtime engine. Here's a tutorial on the remote Front Panel LV development of Applications: http://zone.ni.com/devzone/cda/tut/p/id/3277.

    With respect to the detection of a moving object, you can take two images and subtract to determine if there was movement in the frame.

    I hope this helps!

    You must have installed a Windows 7 64-bit driver (if it exists)
    for this. Do you have? Otherwise, navigate to the web site of the camera
    manufacturer, search, download and install it.

  • Is it possible to record videos from USB webcam directly into Premiere Pro?

    I would get a Logitech C930e USB webcam and record directly in Premiere Pro.

    And, if it is not possible, is there other programs Adobe I can record videos (leave a USB webcam) and then import the video into Premiere Pro?

  • Equium A60 does not recognize the USB webcam

    I just bought a creative vista more webcam and tried to install it on my laptop Equium A60, the software is installed properly and everything but when I connected the webcam to the usb port my laptop didn't recognize it.
    I tried to uninstall and reinstall and nothing has changed. Someone has an idea of what could be bad?

    Hello

    Sometimes USB devices can be recognized correctly because of the low power from USB ports. Usually, USB devices should work with 500mA of power. It is a standard. But sometimes the USB devices need more than only of 500mA. In this case, you can use an external USB hub with external power supply.

    You can also disable the power save option in the device under USB root hub Manager.
    You will find a power management tab. Please enter in this tab and disable the option: allow the computer to turn off this device to save power.

  • Use of USB Webcam

    Hello

    I have been designing an experience for the introductory class in my Department. The idea is to control a system based on color. I had to use a webcam to do this. The problem is that I have a webcam to a 3rd party. Is it possible to use this webcam application? If this is the case, should what driver I download? Finally, how to integrate Vision Assistant with LabVIEW. I need to control the system based on the image capture. I apologize if this seems to be a confused mess. Thanks for any help you can give.

    Hi Andrew!

    Would you be interested to sign up for the beta program Vision?  This will include the new driver IMAQdx, which will include the USB driver update.  To register, go to ni.com/beta to register.  I think it would be a good step in you get up and running.  Please, if you have other questions!

  • Adjust the brightness of the USB webcam

    Hello

    My goal is to get the stream in real-time to images from a webcam for laptop and change its brightness. I am able to connect with webcam. However, I have get the picture and modify using IMAQ BCGlookup.VI to change the brightness of the image, modified image does not reflect the change. I don't know what I'm missing here. If I use a single image (not USB camera but a single stored image Eg..) JPEG) and use this concept then it works but does not work with the webcam acquired files.

    BTW, I have NO vision assistant also installed 2009.

    I enclose the schema VI and block.

  • I have a solid year Usb webcam (syc8368) and when I try and install the driver for windows 7 it never works. Help, please!

    I don't really know how old the webcam is, as this is where I downloaded the driver as the official Web site happy new year seem to take does not support the webcam more: http://www.laptop-gate.com/en/driver-usb-web-cam-solid-year-syc8368/

    The driver .inf file indicates "this file contains information for installation of digital cameras NW800 for Windows 98/2000/ME."
    Extract the files using a utility like 7zip to a temporary folder. Right click on Setup.exe in the folder and choose Properties. Click on the Compatibility tab, and in the drop-down list, choose either "Windows98 / ME ' or 'Windows 2000 '. Click on apply, OK and then double-click on it to run it.
    It may or may not always work; It is a material that is quite old, built originally for Windows 95. Compatibility mode is your best bet, in my opinion.

    The installation file forthis training device is missing a necessary entry. Maybe it's because the file INF was written for Windows 95 or later. Contact your hardware vendor.

  • What can the LAbview with a USB webcam?

    Hi there, I was wondering if someone can help me with my main project.

    I intend to purchase the NI Labview remote control.

    I want to be able to control the distance of Labview Panel through the web.

    Is it easy to generate NI Labview Remote Panel application on my own? I'm still in College.

    or can I buy the NI Labview Remote Panel app for $309 and use applications to control my labview through the web software.

    in this case, I counted about writing software to take the USB camera and post it on the web.

    What can I do with the usb camera?

    can I change the color? hear the sound? you guys can suggest me to do if I get to work with the web?

    Help, please...

    Thank you in advance...

    OK, back to topic.

    A classic exercise would be the detection of changes such as the detection of an object moving for security, etc.. Expand on that and save images when movement has been detected. Another step further, to subtract the background of the object in motion and present a sequence of images of just the moved object.

    Too exotic?

    That level down to a manually-initiated process to do a "what's new? It compares a before and after picture and shows you what has changed.
