• Continuous imaging using vision builder

  Hello, I use NI 1744 and want to know how to get and record continuous images using Vision Builder. I am in a position to acquire and maintain a single image but cannot acquire continuous images.
  Looking forward for your help.

  Bürki,

  You try to save the images continuously as a movie?  This is not supported in VBAI, however if you want to align continuous images individually you can try to change your pattern of State inspection to repeat your current inspection and the transition to the stage stop only after that your current inspection was conducted a defined number of times.

• Vision Builder - error creating LabVIEW Code

  Hello!

  I use Vision Builder 3.5 and LabVIEW 8.5.1. Vision Development module is also installed.

  I've built several routines inspection with the Vision Builder. Then I tried to create .vi-files. Then I hit tools-> Inspection migrating to LabVIEW...

  In the next box I select:

  1-version of LabVIEW: LabVIEW 8.5 - NEITHER Vision 8.5.0

  2 - the directory I want vi-files to be.

  The migration begins, but it is never finished. There is always the following error message:

  Error during creation of LabVIEW Code #3

  I have not found additional information about this error code. So maybe someone is able to help.

  Thanks in advance.

  It seems that the error occurs when you try to play a file which contains the parameters of control of that Vision Builder AI generates. This file may have been corrupted and Vision Builder AI fails to write correctly. I have attached a simple VI to determine where this file lives. Make sure that the file is not present before generating the code and that you have write access to this directory.

  Hope this helps,

• Migrating to labview vision Builder... Many VI

  Hello

  I use the latest version of labview and OR vision builder. Using Vision builder get the coordinates X and Y of the object in this area. I need to export this to labview. I tried going in "Migrating to labview. I created a new folder then I gave the name. When I click OK. It creates many VI. I need this in VI only. When I opened the "main.VI", I see that "make, start." When I check the block diagram. I couldn't find the programe I needed for it.

  Hope you understood my question.

  Can you please help me.

  Thanks in advance

  Another option, which could be used in conjunction with the API mentioned Christophe solution is to your X / Y values the variables that you update your VBAI inspection and then read in your code LV. Here's a tutorial on the use of shared variables to communicate the results to the LV of the VBAI:

  Here is a video showing how to use the API that Christophe has mentioned:

• Cannot acquire image with NI1744 using the interface configuration of Vision Builder AI 2011: error-1073774588

  I use a 1744 OR with NI Vision Builder AI 2011. When I'm in the interface of the inspection, the camera will acquire and display an image. When I go to the configuration interface and try to put in place the stage of image acquisition, I have error-1073774588: the undefined error. I sometimes also 1074396159 error: not enough memory.

  Thank you for your repply Burrito.

  The problem was sloved and two errors went away after I formatted the camera and reinstalled the software on the camera.

• Control of a system of engine not to not 2 - axes of Vision Builder

  Hello

  is there a way to control 2 Motors step by step via Vision Builder?

  What are the components do I need?

  BR,

  Klaus

  Hello knuemm,

  There is no action, which allows to directly control the player. It depends on your hardware configuration, some engines step by step has a serial interface and also the device the vbai is running on other devices of movement has a digital input and some vbai devices have outputs digital that may be used for this.

• run a VI in labview with Vision Builder (VBAI)

  HELO,

  I try to use the 'run VI' tool of the vbai (2010). When I lunch the inspection on my PC (with labview 2010) it's ok, but on another PC (without labview), I got an error message (dll is missing).

  I have to copy the data in a specific folder to use this tool?

  You have solutions to solve my problem?

  Thank you

  If you read the context-sensitive help for the LabVIEW execution step, there will be clear instructions to operate the LLB for Vision Builder AI. I'm not including instructions here because they change slightly depending on the version of the VBAI you are using. However, here are some useful links:

  http://digital.NI.com/public.nsf/allkb/231D87B9D8C3B71A862572D4007EAAF8

  http://forums.NI.com/T5/machine-vision/quot-make-sure-all-of-the-VI-dependencies-including-VI-lib-VI...

  Access the LabVIEW execution step in VBAI, change it, then go to the help > show contextual help (Ctrl-H). In the FAQ tab, there will be a link to describe in detail how to build your LLB for distribution... read carefully and follow the directions.

  Hope this helps,

• Integration of third party Vision Builder C++?

  Hello
  A customer of ours uses NI Vision Builder in an application and questioned on the possibility of integrating our algorithms with her exclusive image processing.  Our code is a C/C++ library.

  I did some reading and downloaded the eval package, but it is not clear to me if this is allowed with the product.  The defined C API allow access to built-in functions, but I've not seen an obvious way for third party algorithms to access images or add new features.

  Vision Builder only supports it the algorithms or can developers add custom product image (in C/C++) processing algorithms?  Thank you.

  Hi eepdx,

  VBAI is not a contribution to the third-party code integrated directly in the script. And you are right about the C API.

  You can use the range of Vision Builder AI communications to communicate with the C++ application. Or you could translate your final VBAI script by LabVIEW code, then, LabVIEW can call a dll, so you could create a C++ application dll and call it from the LabVIEW code (it would be more complex).

  I hope this helps.

• NEITHER Vision Builder to tiara

  Hello NOR the community.

  I built a system to measure through NI Vision Builder. Now I can record the measured data (only!) in a *.csv or *.txt file.

  I want to import the data measured in DIAdem automatically.

  Is there a better way to do it? Is there a direct Interface between the 2 software systems?

  Thanks in advance!

  Hi Steffen,

  When you install DIAdem you are also automatically installing a separate program, called "My DataFinder", which is a database and indexing service.  The tiara and "My DataFinder" use the DataPlugins even index of load/data files.  When you complete a session of text use wizard, it creates and registers a use in addition to load the data file into the data portal in DIAdem.  The idea is that eventually DIAdem both the DataFinder can use the use that you created for the load index / all similar data files.  In practice, the use you get from the Assistant is often not ideal for use with a variety of similar data files.

  My initial inquiries indicate that ASCII files, you are already creating the best leads that we have between Vision Builder and tiara.  The marketing director of DIAdem is now advocating for options in future versions of Vision Builder who could provide a superior connection.  For now, however, I think our best bet is to outfit you with strong DataPlugins which will provide drag & drop of loading in the NAVIGATOR tiara as well as automatic indexing to the DataFinder database.

  So, could you post some of the ASCII files you created with Vision Builder?  I would be willing to create a use or a set of DataPlugins that should give you the basic data functionality and connectivity you are after with DIAdem.  Or you could send to [email protected]

• vision builder to labview migration

  Hello

  I have a project of vision. Pluggable VISION BUILDER pour image processing and the LabVIEW pour interfacing.

  My question is: how to call an inspection done by VISION BUILDER in the LabVIEW software.

  NB: I found in the Tools menu of VISION BUILDER a feature titled "Migrating to LabVIEW. but she could not be executed because I don't own

  the DEVOLEPMENT VISION MODULE. Have to buy another software OR (VISION DEVOLEPMENT MODULE) pour fix my problem? : smileysurprised:

  Thanks in advance

  Hello

  Vision Builder is provided with an ActiveX control that you can call from LabVIEW. You will find enclosed a few Directory promotion the in examples

  \

  The ActiveX component allows to control Vision Builder as you would you interface greengrocers. Once you have created your inspection in Vision Builder, you can use the ActiveX component to connect a Vision Builder of LabVIEW, open an inspection, execute, recover and display the image (you need not purchase the Vision Development Module pour it), and get the results of inspection and each step of the inspection.

  Hoping that this answer has your expectation

  Kind regards.

• Version of LabVIEW for Vision Builder AI 2012 plugins

  Hi all

  II was a little challenging to find out what version of LabVIEW has been necessary to develop customized Vision Builder AI 2012 plugins, I found it by starting the installer, LabVIEW 2011 (but I wish I could find this information in the Readme of Vision Builder AI 2012).

  Now my question is: is it possible to use LabVIEW 2011 SP1 to develop plugins for Vision Builder AI 2012?

  Right... I tried, I installed all versions VBAI and LabVIEW, I could.

  I turns out LV 2011 sp1 is just an update of 2011 and so LV2011 SP1 can be used to develop customized Vision Builder AI 2012 plugins.

• The DALSA X 64 - YEAR QUAD Framegrabber is compatible with Vision Builder AI 3.6

  Hello

  I think use the DALSA Framegrabber with 4 camera inputs. I was just wondering, if this framegrabber is compatible with the Vision Builder AI 3.6?

  Thank you

  The only framegrabbers directly supported by VBAI that are produced by National Instruments, see http://sine.ni.com/nifn/cds/view/main/p/sn/n32:frameGrabber / lang/en/nest/1286/ap/vision.  If your application requires three or more cameras, I would suggest using a pair of PCIe-1430 framegrabber with Camera Link cameras, PCIe-8235 with cameras GigE or using a firewire camera configuration.

• Result variation and inconsistency Ni Vision Builder AI

  I am currently using OR Vision Builder HAVE (2012) to analyze a series of images, and the preparation of appropriate inspections, I noticed that the results are not reproducible.  I am currently using various measures of analysis such as the color of the measure, number of pixels and the strength of edge and using the data logging feature.  The problem is that if I double-click on a stage as if to change, click on transfer to the next image, without changing anything, click OK, and then run all the tests again, I get different results.

  For things like the number of pixels that is relatively small - anywhere.0001 about 3 when it comes to figures around 200, but for the strength of edge especially these range from 10-20 at a time and sometimes he could find even an advantage that is then seen in over 40 years (and the edge resistance threshold is well below this value).  If this is inevitable then I can run many tests and average results, but it will be a lot of time because it also involves the steps wrong edition.

  Mainly, I would like to know if it is common and expected and if there is a known percentage error, or maybe I can change the configuration of the program in an attempt to overcome the problem?

  Thank you!

  The good news is that we have found what is the problem. When you change a step that uses a coordinate system and the current image is not the same as that used during the stage was originally set, the return on investment is transformed to the new position and step updates the settings used for this new position, when you press OK. Rounded the errors that occur when the transformed KING is caluclated, the new system of basic contact information you may not in the same positions of the KING. Kings use integers and therefore round us to the nearest integer, but it does not exactly the same positions as the coordinate system original base product. This may cause the new coordinate system of the step being out of up to 1 pixel and causes the return on investment deal with a slightly different part of the image

  For a given inspection/images, the results will not change unless you change the step that's important.

  If you change a step, but do not want to make changes, press Cancel instead of OK, and all settings will be the same.

  We will study a real fix for this problem that involves only update the coordinate system basis when the user redraws the return on investment, but the bad news is that this correction will not be in the version of Vision Builder AI we are about to go out.

  I'm sorry for this gap, and we plan to address in the future.

  Thank you

• Error - Vision Builder Inspection to LabVIEW Migration

  
  

  You can verify that you have read/write access to your temporary folder (in general C:\Documents and Settings\Settings\Temp).

  This error is due to the fact that a temporary file (VBAI.bin) is probably not written in this file or cannot be read during code generation. Is it present in this folder after you try to generate the code?

  What privileges you have when you run Vision Builder AI? If you are logged on as administrator? You can try to run Vision Builder with administrator privileges and see if you still get the same error?

  Also, what operating system are you using?

  Thank you

• several webcams in for usb or imaq vision Builder

  Hello

  I have a question about imaq nor for usb or vision builder AI 3.6 (I did a vi with imaq and I run in the constructor of the vision) and I want to know how can I connect multiple webcams to the computer, and how many of them can be connected. can they all be of a make and model and can they be executed with a driver installed on the computer?

  Thank you

  Hello

  In general NOR-IMAQ for USB can support only one camera at a time. You can acquire multiple cameras (not simultaneously) using USB IMAQ list VI cameras to identify each device plugged into your system and access it via the other IMAQ live to USB.

  I would also like to point out that Vision Builder AI does not support the NO-IMAQ for cameras USB driver. It is designed to solve machine vision applications, but USB cameras provide in general or advanced necessary for machine vision triggering modes.  Because the machine vision and USB cameras will usually together, we do support USB cameras in Vision Builder AI.
