• IMAQdx Get Image2.vi questions...

  I've been running a program of vission machine for some time.  Recently, I did an executable and Installer to transfer it to another PC and will have questions.

  The program crashes on trying to acquire its first image.  It throws the error 1074360293 to "IMAQdx to Image2.vi.  As far as I can see, nowhere in the program is this called function.  The closest I can find is in the image grab VI, but uses 'IMAQdx Get Image.vi' without mounted 2.  So I don't know why it's looking for it.

  Does anyone know where else this VI could be called from?  To try to solve this problem, I even installed the same Vision on the new PC programs to bring on the same files.

  Thank you

  You will not be able to run even the VI if LabVIEW does not find the file.  But if you can run the VI, the file exists on your system somewhere.

  The VI is actually inside a .llb, so a file search won't be able to find it.  Here's where:

  C:\Program Files (x 86) \National Instruments\LabVIEW 2015\vi.lib\vision\driver\IMAQdx.llb

  The only way I can think to mix the original versions and '2' of the screw are if you have changed the VI on several systems, and each system has had different versions of Vision Acquisition installed.  I can't think of another possibility that would entail.

• IMAQdx.ctl

  Hi all

  I am trying to load a labview program that use the library version

  I made sure I have IMAQdx install with my version

  Yet when the execution is not workeable (broking arrow) as it does not find IMAQdx.dll

  I serch for it in c or labview folder and have found it

  aprricate your help

  Israel

  Hi Israel,

  Please, check that the ctl is located in C:\Program Files (x 86) \National Instruments\LabVIEW 20xx\vi.lib\userdefined\High color. LabVIEW is struggling to locate other IMAQdx screws?

  Please also answer the questions that someone posted on versions of LV and going TO you.

  You try to open an example? Is it a VI you have built from scratch? Please post more details on that as well.

  Thank you

• Folder "devices OR-imaqdx" not appearing is not in the NOT-MAX/USB cameras not recognized

  Hello world

  I have a Dell M6700 running Windows 7 64 - bit, Labview 2012 32 - bit, OR-imaq 4.6.4 OR-imaq i/o 2.8, NOR-imaqdx 4.3 and NI Vision Development Module, 2013 OR MAX 5.5.1 in addition to other modules OR series, xnet, etc.

  I have two webcams, I try to use with Labview. One is the Dell integrated webcam, the other is a Logitech C500 USB webcam.

  Or webcams are at MAX. And in fact, the folder "devices OR-imaqdx" don't market not yet appear.

  Both webcams work perfectly with the "Dell Webcam Central" software, the AMCAP software and Skype. The only software I have and who does not see the webcams is NOR-MAX.

  I uninstalled and reinstalled everything, including the operating system, with no luck at all.

  It seems to be a common problem but I can't find no response except for a possible cause. In one of the posts I've read, one of EI said that NEITHER-MAX requires the registry key "DevicePath" so I wonder if a registry problem is the cause.

  What exactly is OR-MAX looking to recognize webcams and create the folder "devices OR-imaqdx?

  Thanks for the help in advance,

  Mike

  I wonder if this could be a manifestation of a recent problem that arose. Can you try to rename "niu3v.dll" in C:\Windows\SysWow64 and then closing/re-open MAX?

• IMAQdx USB Image capture

  Hello world

  I have Labview 2011 and uses a camera Basler ace acA1300-200uc, which is supported by NEITHER. I have a few simple things I need to do with this camera. First off I have to put in a trigger to my Labview code, saying that it starts when one trigger in another program Labview occurs. Then I need to open a video stream live on the screen for the duration of the test. I have in fact need to record video. In addition, I need to capture an image of the video two or three times in the first thirty seconds of the video.

  I looked through the forums and have found only a few examples of how to do to capture images from a USB camera without having to pay $4000 for the software IMAQdx arounf. I believe that my task is far too simple to justify the purchase of this software that I don't need to deal with images or videos somehow, other than the capture an image of the video stream. Anyone has any advice on how to proceed in Labview?

  I ended up buying a capture card that came with the software for the Acquisition of the Vision, which includes imaqdx. If I had taken the camera through OR I think it would have also accompanied the software and I could avoided the couple extra hundred (but it was cheaper to get the capture card to just buy the software on its own).

• Acquisition of IMAQdx - synchronization problems

  Hi all

  I built a code a VI in which I put in place a camera IMAQdx acquisition in a loop of producer-consumer (see attached VI). The code also controls the camera exposure time.

  I would like to record images at 10 frames per second, the camera is set up to acquire NI Max 10 fps, but surprisingly, the code saves more than 10 frames per second, even if I inserted a synchronization feature in the loop of the producer.

  Any ideas on what does not work?

  Thank you.

  Kind regards

  E.S.

  There are three modes of acquisition of the camera: Snap, sequence and Grab based on parameters that you set:

  Wink (single image acquisition): continuous = 0; Buffer Count = 1

  Sequence (fixed number of frames): continuous = 0; County of buffer > 1

  Enter (Continuous Acquisition): Continuous = 1; County of buffer > 1

  - So I guess you want continuous acquisition, which means that you must set the buffer has more than 1 (usually more than 3) that the driver uses internally to avoid overwriting images.

  -You can check The Grab and configuration example VI attributes that lets the user view the current attributes and settings, update the attribute parameters, acquire images continuously and display images in an image control.

  -From the example above, you can also see the framerate that acquire and then proceed to the backup of images.

  -To access the example help-> find examples--> search for Grab.

• error message "missing resource file imaqdx.rc.

  With the help of LV2010, returned to a PC that has been used for a while access to some old programs of vision. On the block diagram, the property IMAQDX node is disconnected and when loading the file, I get a message that says: "lack of resource file imaqdx.rc.

• Cannot use the NOR-IMAQdx with 3 USB camera driver

  I have a system WIN7 64-bit I would use with two USB 3 Vision cameras (both are 24UJ003 from The Imaging Source DFK), which works very well with the software IC software. The camera can be opened with IC software but will be visible only with a cadence of 1fps, any size I put it.

  I can open them able and Automation Explorer, but they do not appear under NOR-IMAQdx in the tree.  When I click on the software in MAX tree below, NOR-IMAQdx revealed as being installed (14.5). The camera (and OR) instructions say change the camera driver to that found in C:\Program NIUninstaller Instruments\NI - IMAQdx\Staging\NI USB3 Vision, but my driver is located in C:\Program Files (x 86) \National Instruments\NI - IMAQdx\Staging\NI USB3 Vision.

  Attempts to install the driver displays the following message is displayed:

  "The folder you specified contains a compatible software driver for your device.  If the folder contains a driver, make sure that it is designed to work with Windows for x 64 systems".

  This makes it sound like the driver is in the wrong place or it does not for a 64 bit OS.  Any advice on how to switch them TIS drivers to drivers OR-IMAQdx and also how increase the pace of the second camera would be very much appreciated.

  I tried to connect the cameras individually, and they both have the same performance as when they are connected together (we have good pace, and the other has only 1 fps).

  Are you sure that the camera is Vision compatible USB3? Nothing that I do not see in the marketing material says it is compatible. Is it possible you need a firmware update to make it compatible?

  The installer put IMAQdx driver in the space provided for an x 64 system and he always puts the number of correct bits of the driver down to the system that you have installed. My hunch is that the camera is not to expose a USB3 Vision interface for the driver to bind.

  Hello

  IMAQdx supports various configurations of the pixelformats of YCbCr color space, but it seems that there no versions of Pixel Format Naming Convention new mode which explicitly list the exact color space (because there are several YCbCr color spaces). Decoders of YCbCr from IMAQdx are all followed the standard ITU - R BT.601 and support for 8-bit (10-bit variants are not supported).

  You can change your local cache of the file XML Pleora (C:\Users\Public\Documents\National-Instruments\NI-IMAQdx\Data\XML) and replace the enumeration name "YCbCr601_422_8_CbYCrY" by "YCbCr422_8_CbYCrY" (the older generic name that existed before the 601 variant). This should allow the pixel format to correspond to one of the known encodings of IMAQdx and be properly decoded.

  I'll file a bug report internal for the 'YCbCr601_422_8_CbYCrY' (and the rest of the formats similar to this question) added as an alias for good for the decoders we have so that "everything works" in the future.

• are IMAQdx sessions autodisposed?

  I am trying to store the reference to an IMAQdx Session in a FGV, and I can't reconcile with the behavior shown by the following excerpt:

  

  In my understanding, the VI should throw an error on the property node the first time it is run, but not the other. The shift register should be the reference for the session, and so it seems probed (only shows "cam0") and compared with the constant entry. But still, the property node fails also in the subsequent execution. What is happening is there some hidden session state indicator, which escapes when the VI ends?

  The documentation says that session Out is a single reference to the camera. Session Out is the same as the Session . Maybe so, almost the same thing?

  It's LV 2015 32bits.

  Yes, when the first level VI stops running, all sessions of IMAQdx created by it are auto-éliminés. Almost all refunums in LabVIEW works like this.

• use IMAQdx functions in Labview Communications System Design Suite

  Hello

  I would like to read an image and use the bytes obtained to perform certain functions. Currently, the system has Labview Communications System Design Suite (2014 SP1)

  and vision acquisition software installed. I don't know how to use IMAQdx features in labview.  Can anyone help?

  Thank you!

  I do not work with the Design Suite of Labview Communications System.

  In LAbVIEW, however, when after you install LabVIEW first, then the Vision Acquisition, you can use the example Finder locate IMAQ or IMAQdx for LabVIEW examples: in LabVIEW, select help > find examples. This will open the Finder of the example. On the "Search" page, type the keyword "IMAQ" or "IMAQdx" (depending on your device) and look at the examples that come with the Acquisition of the Vision for LabVIEW.

• Error decoder IMAQdx configure enter with the Mono10 Pixel Format

  Hello

  I recently encountered the following problem, so I'm trying to capture images across an iPort CL - U3 Pleora USB3 vision.

  "Error 1074360265 occurred at IMAQdx configure Acquisition.vi.

  Possible reasons:

  NOR-IMAQdx: (Hex 0xBFF69037) no decoder available for the pixel format selected. »

  I always get this error when I switch the 'Pixel Format' to 'Mono10 '. In my images, I use 'Type of Image' 'levels of gray (I16).

  My test code works very well for 'Pixel Format' "Mono8" but not others.

  It is also important to note that in MAX, with 'Levels of gray (I16)' and 'Mono10', it works fine as well.

  Any help will be appreciated.

  Thank you

  Harry

  Have you changed the type of image requested the default value of 'Auto' to 'Gray levels (I16)' at some point? If you have changed this setting in MAX, and recorded, which would explain the error you see. Your code is only to change the pixel format, and there is no decoder available inside the IMAQdx which takes a Mono8 image and returns an image I16 (you would have to project the image with screws of the Vision).

• IMAQdx unknown error 80040217

  Hello

  I have a USB camera (Logitech c920), I want to use in a LabVIEW application.

  I have LabVIEW 2011 SP1 with developer Vision 2011 and IMAQdx 4.3.5 installed on both 64-bit Windows 7 computers.

  The installation of the system is AFAIK identical.

  The camera works fine on both computers using third party software.

  On the first computer I can find the NI Max camera and TAKE a picture.

  On the second computer, I can find the camera, but the NOD gives me the error:

  Error 0 x 80040217

  An unknown error code was met.

  Repoeated attempts to WINK, I get the error:

  Error 0 x 80004005

  An unknown error code was met.

  If I try to create a LabVIEW program, where I use the "Snap.vi", I get the following error:

  Error 2147220969 occurred at IMAQdx configure Acquisition.vi
  This error code is not set.

  I checked the version of 'IMAQdx.llb' and 'niimaqdx.dll' are the same.

  Can someone help me understand what is the difference between my two computers and why Snap works on one and not the other.

  Thanks for reading!

  Hello Oksavik,

  BlueCheese is just that it's not a mistake NOR but an error generated from Windows or, more likely, from the Logitech driver. You said in the other post on the forum that the camera works in your Logitech software, but it is possible that MAX or LabVIEW are trying to charge the device with different initial settings that might be causing the problem. I found a few things that you can try:

  This translated forum post went through the same troubleshooting steps, I recommend you:

  http://translate.Google.co.in/translate?hl=en&SL=FR&u=http: / / forums.ni.com/ni/board/message%3Fmessag...

  It ended up being that the USB cable was not compatible. The other steps listed, reinstall the driver, reinstalling IMAQdx, etc. would be not good to try as well.

  BlueCheese manages these types of errors all the time:

  Some of his suggestions, it would be interesting to study.

• Is there a way to determine if a camera IMAQdx session is still valid or not?

  If it is valid, IMAQdx Open Camera.vi will return an error.

  If it is not valid, IMAQdx Close Camera.vi will return an error.  And IMAQdx close Camera.vi is very slow during the in camera session is invalid.

  I mean IMAQdx Camera.vi open have not yet been called, or IMAQdx Camera.vi Close has been called.

  Although there is no node property for this purpose, other properties, such as the name of provider of camera, are acceptable workaround solutions.

• Do IMAQdx and NI GigE Vision 2.0 material support?

  Hello

  From my brief research, GigE Vision 2.0 has features very nice that I'm at the end which are not supported by previous GigE Vision 1.x standards:

  • Compression on the side of the camera
  
  
  • Timestamp and sync IEEE 1588 (PTP)

  OR those taking? If not, are there any plans to add support in the near future?

  Thank you!

  Hi again,

  Thanks for the extra frame.

  Assuming that your only using the camera is saving JPEG images on the disk, and you are concerned about the performance of the acquisition system, I think that an IP camera might be a better choice. These cameras acquire images compressed, so you can very well save the direct-to-disk with no extra charge. This will save time and bandwidth of the network processor. The bandwidth would be nice because you could probably just run 6 cameras in a gigabit switch and connect to a port on the PXI chassis instead of several 8234 ports. This is possible because not only if bandwidth is reduced, but the IP cameras can use TCP and sharing bandwidth much more enjoyable that can cameras GigE vision. To save the raw images on the disk, you can use the IMAQdx VI "Get Image Data", which is a JPEG file that you can save directly to an IP camera.

  Regarding the time stamp data, depends on the accuracy required. Since you recorded all the time after that image returned, is quite imprecise because it is not really correlate with the acquisition time. You might get a more exact time in two ways: record IMAQdx a CPU timestamp on receipt of driver that you can use (useful if the CPU is synchronized to GPS/NTP or similar) or you can use a timestamp saved in the image itself in the form of metadata (GigE Vision and IP cameras can do that). I think the Basler IP cameras can use NTP and testify to the time stamp for metadata EXIF JPEG images that you can extract. This mechanism is of course much more precise because it eliminates the delay/jitter of transmission at the time. If you have a few requirements of precision (microsec, milliseconds, seconds?), it would probably give a better idea of what your options are.

  I suggest you take a look at the range of cameras from Basler IP. You can not control the parameters of the image directly in the IMAQdx driver (you must use their web interface, or write additional HTTP code), but once you have the configured device it will keep these settings.

  http://www.baslerweb.com/en/products/network-cameras/IP-fixed-box-cameras

  It is likely that the cameras will be more expensive that some cheaper GigE Vision cameras can be, but I suspect that you could save enough on other system costs will in this way to make up for it. In my opinion, doing compression JPEG on-the-fly with 350 + MB/sec of camera raw data could be difficult, unless you had a tough multi-core system.
