• How to create own IDE for LABVIEW (such as vision builder)

  Hi all

  My pretty funny question, I know that.

  I like to create Labview Application IDE like Vision Builder.

  How to do this?

  As far as I know that Vision Builder is developed with LabVIEW, the source code of course is not public... But why do you want to create a new IDE for LabVIEW? LabVIEW is an IDE, no?

  I think also Vision Builder uses a lot of scripts and sub-panels, I can't help you much more than that.

  For us - outside NI - script cannot be used in an EXE file, they reserve that for their applications not it will be a difficult task.

• default transition in vision Builder

  Hello

  I am a new user of Vision Builder AI 2011 and have a question about the transitions between States (default).

  In a testapplication I build for different features of Vision builder I want to create 3 States, each consisting of a series of tests. It works without problem.

  But the problem starts when I want to put an end to the test during one of the inspectstates does not pass. To do this, I added 3 (fault) specifies in which I put an overlay so that the reason for the "failure" becomes visible. The transition to these States 'fault' is changed so that the transition is only used when the above report fails. Each of the 'fail' states has a transition directly to the outcome.

  The problem I encounter is that, even when any of the tests fail, the program works always true all the other tests.

  Reason (I think), it's that I can't change the default transitions (ranging from inspectstate to inspectstate). And seeing that you cannot delete or change the default reports I can't find the solution to this problem.

  I've considered adding another transition between the inspectstates and to change this transition, but what to do with default transitions?

  Contribution to this issue would be greatly appreciated. I only started working with Vision Builder, but I see endless possibilities, if this problem is solved.

  Thank you

  Tom

  Hello

  After having a quick glance at your program, it seems that everything is OK, (as you did not provide the images, I just looked after the transitions).

  Your transitions are good, so if an error occurs in a processing status, go to the final State, and other States will not work.

  But what make you think that other States are good that the program doesn't run?

  You can run your sript in Setup mode after adding a delay in all States. You will then be able to see in schema view that pass are valid or not.

• bug in several functions of IMAQ vision mask

  Some functions IMAQ Vision bad work if you use the image source as the mask. I keep running into this bug in IMAQ Vision, Vision functions exhibit this behavior, and others do not. It is not documented in job descriptions. Even if it were, it would still be a bug. Example:

  1. create an image source U8 containing zeros and nonzero values.

  2. son of the image in the entry source and IMAQ mask entry quantify and return the value of % of the global report to see what percentage of pixels are different from zero.

  The answer is wrong. If you copy the image in a separate image first and distinct picture of wire in the input mask, you get the right answer. See attached VI for building

  

  See you soon,.

  -root

  If someone knows a way to return the number of pixels not dummies in an image without duplicating the image in memory, please post the method here so I can mark it as a solution. I find that using IMAQ getpixelvalue in a double loop is extremely slow, even with a shift as a counter register.

  Using the histogram IMAQ VI seems to work (with no mask image)-the first index of the returned histogram array is the number of zero pixel, so the sum of the table no less (or less area this) is the number of pixels non-null.  The VI has the same bug with the image of the mask (and I agree with you that document a bug does not correct!) but at least you can use for this problem.

  Hi all

  I'm new to Lab Windows/CVI and uses the library imaq vision.

  Could someone tell me where I can find the reference of function IMAQ Vision? I found a function reference manual at first--> National Instruments--> Vision--> Documentation. But all the functions described in this document are starting by img * (). I was looking for functions starting with imaq * ().

  I'm sorry that it might be a stupid question, but any help would be appreciated.

• Several acquisitions of IMAQdx USB camera simultaneously

  Hello

  I am trying to acquire 2 or more focused on the USB webcams at the same time, but one of the cameras always error. I replaced IMAQdx ENTER with IMAQdx SNAP and that seems to work to capture frames. But I would really like live food to webcams both (or several) if possible. The idea is to consult the live wire of two cameras and make necessary adjustments in the rest of the material to my system and then begin to capture images every 10 seconds approximately (from two or several webcams).

  Attached, multicamera_op_v1 = VI to get two webcams live food.

  multicamera_op_v2 = VI to get direct feed from two webcams and then captures frames from two cameras.

  I would like suggestions.

  Thank you

  
  

• The PCIe for USB 6211 OEM replacement

  Hi you all,.

  We want to change our design to use PCIe card data acquisition, since we had a few USB driver problem in the past. Is the PCIe-6321 a good match to replace the capture USB-6211-OEM card

  Is there a better alternative?

  Thank you

  Fabrice

  Hello Fabrizio,

  Thank you for taking an interest in our line of PCIe cards DAQ. I took a glance at the USB-6211 OEM and PCIe-6321 to see if they are similar in specifications and capabilities. I would say the 6321 is a good match to replace your current USB card. As long as you intend to use no more i/o lines than expected or exceeds the designated sampling rate then it should be a good substitute.

  If you need high speed sampling or more i/o lines for various tasks, then another card can better meet your needs.

• How to download imaq vision

  I am a new user of labview and I wish to study this subject IMAQ vision. However, for the same thing, I have no idea as to how I can use it on LabView. Smoker I don't understand if I have to download additional software for IMAQ Vision work with LabView. Kindly advice me.

  Jean-Luc

  NOR-Vision and NOR-IMAQ are two different things. NOR-IMAQ is a set of drivers and software to acquire, view and save images of some devices. The supported devices are in the readme file. This software is free. NEITHER Vision is a software level. He did work with a wider variety of devices. It is not free.

  I think that it is best to call your local sales office OR that they would be better suited to help you, rather than this forum. We mainly answer technical questions here.

• IMAQ Vision: (Hex 0xBFF60403) copy unauthorized IMAQ Vision.

  Hi all

  I have a Labview program developed a few years ago by one of my students who use some images from a camera to do some analysis.

  It's the environment that was used:

  Windows Xp professional version 2002 Service Pack 2

  LabVIEW 7.1
  LabVIEW Run-time Engine 6.1 - 7, 0 - 7.1.1
  NOR-Imaq 3.1.0
  IMAQ vision 7.1.1
  NI-Visa 3.1
  NOR-488. 2 2.40

  NOR-IMAQ 3.1

  Application Builder 7.1

  Now, the PC crashed and I tried to restore all the software and VI.

  I got these (3) types of errors when I lounched the VI:

  1074396157 error occurred at WindShow IMAQ
  Unauthorized copy of IMAQ Vision.

  1074396157 error occurred at WindSize IMAQ
  Unauthorized copy of IMAQ Vision.

  1074396157 error occurred at WindMove IMAQ
  Unauthorized copy of IMAQ Vision.

  Possible reasons:

  IMAQ Vision: (Hex 0xBFF60403) copy unauthorized IMAQ Vision.

  I read that it is possible to overcome these types of errors lounched visionXXrte.exe, but I don't have on my PC.

  What can I do?

  Thank you for your help

  Hi all

  the problem has been resolved.

  It has been necessary run the NILM License Manager and activate the product of the Vision, which has been exceeded (I don't know why).

  So, thanks to all the world.

• Lost file "IMAQ Vision example Folder.vi"

  Hello world

  I was working with this file and I lost it. Now, I could not find or fix also I re - install all the modules of the vision, and many examples use this file to take the path of the image to work. Someone can help me trying to find the path and bring me the IMAQ Vision example Folder.vi

  Thank you for your cooperation,

  John

  Hi, thanks for your response, I did it and I don't know why, but did not work. I solve the problem using the IMAQ Vision AVI Folder.vi and change the block diagram and removal of some parts and then rename it as the vi that I lost. In this way, I solved the problem.

• Vision Builder for Automated Inspection Development Toolkit missing / cannot install in 2012

  I try to install the VBAI SDK.  I have licenses and have installed:

  OR LabVIEW 2012 Professional Version

  Toolkit OR Vision

  OR in real time

  I find not all options in 2012 LabVIEW for the VBAI dev kit so I tried to run the install and it says:

  "The Vision Builder for Automated Inspection Development Toolkit requires LabVIEW 2011 be installed, please install LabVIEW 2011..."

  Why can I install it on LabVIEW 2012?  2012 is out for 1 year... How VBAI does not support LV 2012?

  Should I install Labview 2011 to make this work?  I don't have the DVD for 2011 so it will be a royal PITA to install.

  

  Hello

  > Why can not install it on LabVIEW 2012?

  VBAI 2012 is a LabVIEW application that was built with and require runtime LabVIEW 2011.

  The VBAI SDK, just like the run LabVIEW stage, require the same version of LabVIEW VBAI was built with.

  We could technically remove this limitation under Windows, which would have implications serious performance the performance of the custom steps, but many customers who design custom steps also want to do on targets from a distance (for example smart cameras, EVS or CVS). Currently, it is not possible to support several facilities next to LabVIEW on real-time targets. For this reason, we have decided to only support that has the version of LabVIEW VBAI.

  Please contact your sales representative OR to get a copy of LabVIEW 2011 you need for the SDK.

  The next version of the VBAI (2013), support 2012 LabVIEW for the SDK and run LabVIEW steps.

  Best regards.

• Error 1074395720 has occurred to IMAQ find circular Edge 3 IMAQ Vision: invalid KING.

  Hello

  I am writing a program to adapt to a circle of an image (from the avi), but when running the IMAQ find circular edge v3.vi I get the error message:

  "Error 1074395720 occurred at IMAQ find circular Edge 3.

  Possible reasons

  IMAQ Vision: Invalid KING. "

  I use the vi KING of construct IMAQ to set the return on investment and I am sure that the KING output is in a format suitable for the discovery of the IMAQ circular edge v3 vi.

  I joined my program (Labview 2011)

  Any thoughts?

  Thank you very much

  Rory

  Hi Rory,

  Welcome to the Forums of NOR.

  «IMAQ find circular Edge 3' expects a return on investment for type 'Ring'.» There are a number of functions in labVIEW for the conversion of the type of return on investment as "IMAQ convert the KING to ring. However, as the circular edge VI find JUST does not ring but bounding box and other details as well, there is a strange solution to this problem.

  Drop-down "IMAQ convert KING ring" and get the return on investment through. Drop-down and then "Convert ring to the KING" (Yes, really) and pass the output of who to "find the circular edge.

  It is circular, strange workaround, but it seems to force the type of return on investment to go to the ring and so works.

  Let me know if you have any other questions.

  Thank you very much

• IMAQ Vision: image not valid type

  I use the evaluation version of LabView Pro and Vision Builder to process a video taken from a Webcam from Microsoft. I try to apply a part of the function as a filter of treatment or look at a histogram as graph below but LabView always returns invalid image type.  I assume that these functions cannot process the image directly from webcam (using Vision acquisition) and may need to be converted before their transformation. However, I'm unable to do it. Please give me any suggestions or provide that I have to use the function

  

  In most cases, WebCam will deliver Image RGB (color). Even if you have turned on the WebCam in grayscale mode (then RGB components are equal). IMAQ polygon can handle the U16 only U8 I have 16 or types of SGL.

  What you can do:

  (A) use IMAQ ColorHistograph instead of the polygon IMAQ.

  or

  (B) convert your color to grayscale image (good way is to take ExtractSingleColorPlane IMAQ and set the type of intensity. Destination image must have type Grayscale U8). You will then be able to use IMAQ polygon.
