IMAQdx Open Camera.vi very slow

Hi all

I use a firewire IEEE1394, a camera with IMAQdx with labview 2009.

1. I have configured MAX camera and tested. It works very well.

2 - I used the "Grab and attributes Setup.vi" Labview examples. With the vi, it takes about 1 second to find the camera and it works fine.

3 - I copied the Camera.vi of the IMAQdx 'open' this example in my own software. When I run it takes about 20 to 30 seconds to open the camera. He finds it, but it is extremely slow.

4. to test, I opened at the same time the 'IMAQdx open Camera.vi' 'Grab and Setup.vi attributes' and my request, set the name of the camera on the two clones and run one after the other: I still see the same behavior: the first (from step 2) takes 1 second to open the camera, while the other (from step 3) takes 30 seconds to open without sending an error message.

I came to the conclusion that there must be a link somewhere to a file of configuration or something that makes the fastest start-up in one case than in the other.

Has anyone experienced something similar? / Did someone has an idea on how to solve this problem?

  • -1074360266 error to IMAQdx Open Camera.vi

    Hello

    We have problems with our LabView vision system; the VI is able to "run" with an intact arrow, but there is an error that appears:

    "Error - 1074360266 occurred to IMAQdx Open Camera.vi" with a possible reason of "NEITHER-IMAQdx: (Hex 0xBFF69036) Impossible to reach for the driver in kernel mode.

    For a little history, we had initially scheduled the VI in LV2009 (where it worked fine), but the customer upgraded to LV2010 (where it now comes up with this error), so it would be logical that it has anything to do with the problem.  In addition, we use two cameras Basler A601f via Firewire connections, which both are recognized by the Basler pylon Viewer software, so we're pretty certain that it's only a problem of LabView.

    We have tried to reinstall the drivers of Acquisition of Vision software, but it does not solve the problem, so we gradually loss.

    Any help or pointers are appreciated, and I apologize in advance if I've left out any relevant information.  Thank you.

    Ben,

    Are you able to find the camera and get him to the MAX?  Also, what version of IMAQdx you have installed?  Driver versions are MAX on the software tab.  Because all this happened after an upgrade to a new version of LabVIEW, I suggest to re - install device drivers CD, then reinstall the software of Acquisition of Vision.  I would like to know how this happens.

  • Camera not found, error 1074360311 occurred at IMAQdx Open Camera.vi, USB cameras labview 2013 64 (bitts)

    I use USB cameras with labview 2013, and I can acquire images in the MAX and in the Acquisition of mink (express) settings, but when I run the VI, always appear the same error as shown in the Image below.

    -J' checked the correct versions of my software, IMAQ, IMAQdx, VDM 2013 IMAQ of e/s

    -J' I also make sure I had all the updated device drivers.

    -I'm using IMAQdx LKD schema and examples, getting the same error uu

    Help, please!

    Any suggestions would be very helpful.

    If it works in the pop up app Express VI and inside MAX (the two 32-bit applications), then I guess it will work in 32-bit LabVIEW. We wonder why it does not work in 64-bit LabVIEW, but these are the drivers of the device and other pieces of infrastructure/DirectShow Windows.

  • Reference open VI is very slow if VI is not already loaded into memory

    I have several .lives in my project to be opened asynchronously. I noticed that in the development environment, it took significantly more time to open a reference when these .lives facades were not already loaded. For example, it took 7 s for node reference to open VI finally vs 900ms if lives the façade was already open.

    Here's how I got the reference time it took to open VI Ref process:

    Reading the forum, there were several subjects reported, but they were old enough. I'm using Labview 2015 32 bit. I didn't technically reference time in executable environment, but I remember that it could not be no where near 7s to load a lives of size 500 KB.

    Tests for several different .lives gave similar results, the loading time depends on the complexity and size of the vits. But the size of code and complexity shouldn't matter, does it? I was going to open just a ref, did not have even the VI Run node. What could cause this problem and how to fix it?

    Moreover, this "support period" all the LV project environment seemed to hang and entered spinning wheel mode. Others running VI also suspended and resumed has finished loading.

    VI loading was saved in an earlier version of LabVIEW so that the loading time is increased because you have to recompile it for the version of LabVIEW you now open in it?

    recently purchased a samsung NX30 camera which came with lightroom 5, after several hours of searching on Google I got it setup properly with the right camera raw to be able to access my raw images. I found that my old laptop is very slow during the processing of hundreds of images that I usually take on a weekly basis.  I bought a new faster laptop, but when I looked for the cd with the software of series and I couldn't find in the mess of Christmas.  I downloaded a trial version of lightroom and got, it works on my new laptop. Is there a way to access the serial number of my version already installed and insert it in the version of track to make it work for me?

    Myron

    If you take the time to register to your original with Adobe installation (which most people do not), you can log in to your Adobe account and get the serial number. If you use a Windows computer and still have access to the old computer where Lightroom is installed, you can do the following:

    1. in the window folder options, make sure that you are able to see hidden folders.

    2. go to the C:\ProgramData\Adobe\Lightroom folder.

    3. use Notepad to open the file, Lightroom 5.0 Registration.lrreg

    You will be able to retrieve your serial number of this file.

  • 7 Firefox is very slow to opening pages as compared Web o firefox6

    Compared to firefox6, this version, ff ver # 7.0.1 is very slow to open Web pages. It takes a long time to display the Web page. I tried to disable add ons and did everything I could, but it seems that there is a no solution.

    One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

  • Satellite Pro U300 very slow opening programs

    Hi all

    I bought a Satellite Pro U300 in February 2008 and I only use it 3 - 4 times since then... It is very slow at the opening of the programs (I have only one statistical program installed) and Web pages and creates problems when I try to download other programs that have a different version of Windows Vista.
    I really regretted buying this phone and I'm looking for someone to sell.

    Until I do, I was wondering if I could uninstall Windows Vista and install Windows XP for example, or do anything else that would make my phone fun to use.

    Hello

    The preinstalled operating system ran slowly because many applications are running in the background.
    My laptop was slow too to experience of applications have been disabled.

    You can disable in MSCONFIG.
    Type msconfig window RUN and check the Startup tab.
    You will find the software that could slow down the operating system.

    With regard to the installation of Win XP.
    Yes, you can also install Win XP. By using the Win XP laptop should be little faster because Win XP doesn t need a lot of material resources.
