  Can someone help me to follow a vehicle using vision builder?

  The object tracking feature to track multiple objects.

  To do exactly what is shown in the video, where the number of cars is variable, you must use the LabVIEW module and the development of the Vision to have more control over the creation of objects. (The limitation with Vision Builder AI, is that each object to track is associated with a follow-up session, so you should know in advance how many object you must follow, but VBAI to track multiple objects).

  The principle I described should be the same in LabVIEW: detect somehow the new car which comes within the field of vision and learn at this time where the object so that it can be followed. The prerequesite should be that you need to know where to detect them the car that comes in the field of vision. The difficult part of the application must define the area of interest of the new object that you want to track.

  The LabVIEW example for tracking of objects can be found here:

• NEITHER Vision Builder, acquire Images with fake delivery

  Hello world

  I am a student and I work as a trainee in a company, which produce helmets.

  To control the quality of helmets, there is a Webcam, wich take pictures of each helmet product.

  These Images are saved on the server. With the tool 'Simulate delivery', I can analyze the images, which are now in the folder.

  But when a new Image is the drop in the folder, I actually start the inspection again.

  How can I realize that NI Vision Builder always takes the current Images in the folder?

  Thank you very much for your help!

  Best regards

  Romain Menz

  Here is a simple example that illustrates how to dynamically read the images from a folder. Once the image has been retruned to VBAI, the image file is moved to a subfolder called Complete, so he has not read again the next time step is called. Step returns an error if there is not more images of the file type in the folder.

  Hope this helps,

• 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.

• Build/update dynamically the table 3D

  Hi all

  I'm having a problem with the dynamic generation of a 3D of the following set of data table:

  x: {1,2,3,4,5}

  y: {1,2,3,4,5}

  Z_1: {1,2,3,4,5}

  Z_2: {1,2,3,4,5}

  Z_3: {1,2,3,4,5}

  Z_4: {1,2,3,4,5}

  Z_5: {1,2,3,4,5}

  where there is (5) Z amplitudes associated with each measurement location.  What I am able to statically (from the above values x and y tables 1 d and 2D table Z) is to create a 3D Board made up of x and is indexed intensity to the graphic format of the 2D tables.  Each page of the table corresponds to each of the 5 Z amplitudes measured at each location.  In the attached VI, the Array Build function works perfectly for the static case where the entire data is available.  I followed the example of a another discussion forum will be subject to the provisions of nest two loops construction 2D array in the inner loop and incrementing the pages on the outer loop. The static situation is resolved.

  However, my goal is to graphically present data he is taken, point by point, to the user.  The other attached VI simulates this scenario, incrementation of x and y positions based on the measure button.  Z matrix indicator shows that the 2D Array (each individual page) is in the proper format.  The construction of the 3D picture is dynamically where I'm having problems.  I tried to build table and replace a subset of table, but none of these functions to produce the desired result.

  In the case of building table, 3D table is correctly based on the first measure: for x = y = 1, 2D array page0 is set Z_1 in position (1,1), page1 has the Z_2 value in the position (1,1), page2 Z_3, etc..  However, on the second measure, as expected, the berries are concatenated page5 have Z_1 values in the (1,1) and (2,2) positions.  This result is properly formatted, however, should the counted array 3D page is limited to 5 (page0, 1, 2, 3, 4).  So ideally, page5 should in this case replace page0.  So build array results in the correct format but concatenation is not desirable.

  The subset of spare board was made with the index of the page (outside of the loop) number to specify the subset of the 3D Board needs to be replaced.  The result was an empty 3D array.

  Thank you any help to solve this problem.

  Any suggestions on how to handle filling out table 3D of unknown size?

  If the size of the final table has a reasonable upper limit, you can initialize an array of slightly oversized, then keep using the subset of the table replace. It will be much faster and more effective memory than gradually more and more large networks.

  When the purchase is made, you can cut to the final size.

  Aircraft add to a table 3D using 'insert into array' or 'Build array' (favorite?), cause memory frequent shifts and might slow down your code by orders of magnitude in casing of excessive fragmentation of memory.

  Hi, Shada, this can happen if you include additional installers to your installer for example DAQmx. When you do this the installation program must include other files like MAX (Measuremente and Automation Explorer). Probably when you installed Vision Builder he updated MAX, so when your Installer try to understand MAX, his request the source where it was installed in your computer in this case Vision Builder.

  Here you can cache information so it is not asked once again, or you can download a version more recent fo DAQmx, then it will update MAX and change the dependecy.

• 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.

• black bands - the problem of bandwidth - Vision Builder HAVE

  Hello

  I have a problem with an app where I anime shows Vision Builder 4 on 1 computer. Everything seems to go well until after some time (sometimes minutes, sometimes half an hour) I get horizontal black stripes on my images.

  I searched this forum and found many posts on this problem. However, I tried the various solutions that have been proposed and this does not seem to make a difference.

  Information:

  * 4 camera (Allied Manta G201C)

  * camera is triggered (rising edge) separately, but almost simultaneously.

  * PC: quadcore, 64-bit, Windows 7 64 bit system

  * Run-time Vision Builder 2012 license.

  * Programmed with Vision Builder HAVE 2012.

  * Switch: 1000 MB

  * Interface programmed in c# (receives images of the relevant info 4 programs and displays on the screen).

  Proven methods:

  * Sets the size of the packets to 1500 (even tried low size of package without improvement).

  * Set desired maximum bandwidth to 250 no improvement (was initially set at 1000 - we put it to 250 because there are 4 camera - even the 150 configuration does not seem to improve the situation.)

  * cursed a lot - but which did not help either.

  * Can use us a switch that does not fit our goal?

  * Our switch is placed with several engines around it (the closest on a meter away) and just behind a cabin of electricity in which there are several transformers. That reach our data?

  * Other suggestions?

  * Please let me know if you need additional information about this problem.

  We expect our customers to visit us the week next to see if we will be able to start production and we are currently under enormous time pressure (and stress). So, any help would be greatly appreciated.

  With sincere friendships.

• How to disable the warning of validation on the calculation (read-only) field in the table

  Is it possible to add a line in a calculation script (JavaScript) that prevents a dialog box of a calculation field validation?

  Scenario:

  • Working with fields in a table inserted.
  • In each line, I have a couple of fields that the user has entered. These fields have a Validation model has allowed that the user must enter the data correctly.
  • There is a calculated field based on the data entered by the users. It is this field that throws a warning dialog box "the value entered for Total_Row1 is not valid. "To ignore the validations for Total_Row1, click on ignore.

  Even if I turn off the Model Validation on fields used for the calculation of the warning dialog box always appears. So, it seems to be isolated in the field of computing.

  The calculation area displays the time and I got it originally set as a Date/time field, but also tried to use a text field (as the calculation should appear as 0:45 for 45 minutes in this area).

  I have a suspicion that the warning appears only because I used an array for formatting fields, as I used similar validation profiles and other calculation fields and see not the message when the fields do not appear inside the table.

  I think of easier workaround would be to disable validation for this particular calculation field, but I have no idea how the script that. Any help appreciated lot.

  CARI

  I discovered the problem.  In a word: it was a mistake by naming the fields.

  • I have fields named with line numbers in the field name (for example FieldName_Row1).
  • and fields calls with FieldName_Row1.formattedVallue must have triggered some confusion.

  As soon as I removed the word 'Row' of file names, the question of the warning dialog validation mystery Adobe Acrobat for the calculation field have disappeared.

  Ago about 3-4 hours of my life that I won't be back... ha - ha but if someone else has the problem, I thought I better share my discoveries

• How can I disable features of the Android device in my application to build PhoneGap?

  Hi, I have implemented a simple application in Cordoba and downloaded the Phonegap Build project.  The application compiled with success and I am able to use the QR code to download the application and install it on an android device, but the installation identifies that the app should have access to details of private life and the device features that my application does not need.  In short, it looks like the app to request access to EVERYTHING by default, including the camera, audio, GPS, contacts, device files, user accounts, control vibration, audio settings, etc.  My hope is to disable all unnecessary items, which is probably about all that in the case of my application.

  Looking through the PhoneGap Build documentation (to PhoneGap Build Documentation), it seems that I should be able to disable all the features by adding the following to the file config.xml of my project:

  < = "permissions" option name value = "none" / >

  I did it, but this does not change the application's permissions request access to when it is installed.  He always requests access to a long list of unnecessary features.

  What should I do to remove these permissions of my project?

• Vision Builder HAVE: (Hex 0xFFFA960C) cannot open the record of inspection.

  I HAV built an inspection in the generator of vision for automated inspection (the code, the image and inspection is provided in the attachment)
  but my program cannot open the inspection is to launch an error: error-354804 occurred in VBAI Interface - open Inspection.vi.

  I am using the NI 1742 smart camera and run the program on the remote target

  I don't get the reason for this error.

  If smbdy can solve... Please...

  I think the problem is that the path you specify is invalid for a goal of RT. On the RT, the 'path' should just be the name of the inspection. If you look at help for the VI open Inspection, it says to use the get target Inpections VI to see what paths for all controls are... sometimes the path is a name of numbers subsequent, though it may not be what you think.

  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.

• 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.

• 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

• 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.
