NI Vision Builder test affichage LED

Bonjour,
Je dois réaliser un banc d'essai pour vérifier les LEDs d'une carte électronique.
Le logiciel Vision Builder fonctionne parfaitement bien pour faire cet essai.
Mon problème est plus sur le matériel.
Si j'utilise Vision Builder, me faut-il un autre logiciel supplémentaire ? besoin de labview ? J'utilise actuellement la version d'essai.
Faut-il une caméra spécial compatible ou n'importe quelle caméra peut convenir ? (USB ou Ethernet)
Merci d'avance.

Bonjour,
Merci d'avoir posté votre question sur le forum de National Instruments.
Je pense que vous pourrez trouver les renseignements nécessaires sur les liens ci-dessous.

Registration of several reference images in a test image using vision builder

I have downloaded the trial version of vision builder, and I am attempting a test to determine if it's worth buying:
I would like to determine the position and orientation of two reference parts within a set of test images. I am able to load the reference images, obtain the grayscale, perform appropriate filters, determine their global orientation based on some straight lines, and select the desired ROI's that I would like to match up. I am also able to load in a test image, take the grayscale, and filter it. My state diagram has three heads with the three loading steps that converge. This all seems to be great, but how do I find the position and orientation of the reference ROI's within the test image?
I would like to use something like the geometric matching tool, but it only seems to work on using a part of a first image on subsequent images in the same folder. I suppose I could use my reference as the first image in the folder, then loop through the remaining ones, but...
Once I find the position and orientation of the first reference in the test image, I would then like to find the position and orientation of the second reference in the same test image, then report values like relative distances and angles between these found references.
Does this mean I need two folders, with their own reference image and the same set of test images? Would I combine the geometric matching results using some variables or math functions?
What is the best way to perform this image registration in vision builder?

RSFree101,
Thank you for your interest in Vision Builder AI. If I understand what you are trying to do, you are looking to compare the position locations of two separate parts in an image. We have a tool that does this very well. If you use the pattern matching to find both instances of the part, you should be able to determine the distance and angle between them relatively easily. To do this, you will need to find an edge in between the two so that you can justify the angle between them, and then simply use a few Geometry functions to actually find the angle. To record this information, you can simply use a Data Logging step to write your findings to file.
If you are looking for a more complete analysis on how you might be able to do this, you will need the Vision Assistant on your computer (if you do not have it already, you can get it by downloading a free trial of our Vision Development Module). In the Vision Assistant splash screen, click on the Solution Wizard. This pulls up a menu. From there, go to Tutorial » Bracket Inspection. Click Load Solution. If you step through that example, this displays how to do what you are looking to do with the Vision Assistant, but it should be no different at all in Vision Builder AI. Hopefully this helps.

Integrate Vision Builder 2009 (VBAI), into Test Stand 4.2.1?

Does anyone know of an easy way to integrate Vision Builder 2009 (VBAI), into Test Stand 4.2.1?
earlier versions of Vision Builder seem to accomidate this very easily. But i have not found the same ease to make this work in the newest version. any ideas?
Thanks

Hi,
Thanks a lot for your support.
Well...yes I followed the instructions in the ReadMe.html file.
I have loaded the sequence "Vision Builder AI TestStand Examples.seq" into TestStand.
TestStand crashes after some delay when trying to select the first test step "Run Inspection once".
TestStand obviously has problems loading the Vision Builder API functions and the engine (whatever is necessary).
As I could not succeed testing VBAI 2010 from TestStand, I then tried the LabVIEW example which is also located
in the \examples folder.
I had no problems loading the "LabVIEW API Examples (Local).vi" into LabVIEW 2010 and execute it.
This example works without any problems with a simple USB Webcam.
I can test different "Inspections" and studied the API functions in this VI.
So the problem is only related to TestStand.
I am wondering whether TestStand has problems with the evaluation version of VBAI 2010.
When executing the LabVIEW example the VBAI engine asks me first if I want to evaluate the software (as it is not activated yet).
I never reach this point from TestStand. It crashes before.
Another point is that I am asking myself why the test step "Run Inspection Once" is the first test step the TestStand sequence.
Comparing the sequence of steps with the LabVIEW VI, you can see that there is a differnce in the initialisation sequence.
The LabVIEW VI launches "VBAI Interface - Launch VBAI Engine.vi" first before all other API VIs.
I could try to change the TestStand sequence and introduce additional initialisation steps before "Run Inspection Once".
I simply fear that TestStand crahses again before I have been able to change the sequence.
Ok...another thought...on your system it is working fine using the example TestStand sequence?
This means that the initialisation of the VBAI engine is automatically executed.
Which process is responsible to initialise the VBAI engine in TestStand?
Perhaps I have to configure something ...somewhere in TestStand.
Ok... that's it for now... i will try out a couple of things....
Thanks again for your support
Best regards,
Carsten

Vision builder ai

Hello,
I have a problem by LED function inspection test. This is on Vision Builder AI program. There is a camera, it captures an image. The images have a little different gain, brightness, contrast values, so the later inspections have different measure values. I would like to make a picture comparison between a captured image, and a reference image. After then, I would like to set the gain, brightness, contrast values automatically, like the reference image.
How can I make this? Whitch program? LabWIEV or Vision Builder AI?
Thank, for your help!

Dear koma1989!
Is your problem still open?
If yes, I suggest you to try with VBAI first, and if the results are not good enough, you can change to LV to create a more traceable application.
In VBAI, (I'm using 2011 SP1) please choose the "Other.." option from "Run Inspection" section. Examples will open, and you can try out some, so you can get started easily in VBAI.
I don't think there will be an already working solution for this application, but in my opinion you could put it together from example applications.
If an example appears in Inspector interface (In title you can find "...-Inspector-..."), you can switch to edit mode via Inspection >> Switch to Configuration Interface
From the examples I recommend you the followings:
- Tutorial 4 - Tow cameras inspection
- Classify Colours Example
- Inspect Contours Example
- Segment Color Image Example
- And examples related to State diagram, since you have to check for differences, and than correct the image, so some processing regarding to the differences.
I hope browsing examples will help to get some ideas, if you have any other questions, please don't hesitate to post them.

Extract red image with Vision Builder Automated Inspection

Hello
I have 2 camera connected to a CVS and I want to process the images to have only the red part of the images.
for that I tried to use VBAI but I din't sucess, I think nit should be in the vision assistant step, but I already tryed with "extract a color plane" and "treshold color", and when I test with an image it don't work.
Does anybody know how to that?
Thank you for your help

Hello
I may be find a way to delete everythimg that is not red by substract green and blue with vision assisatant, it seems to work.
Now I try to extract only little part of the picture, only the part of the picture who are red, for that I created ROIs for some red parts of the images, and I want to record only this ROIs, to reduce the size of the file and kipping the same resolution.
Does anybody know how to do that?
I attach my Vision builder code to the message
Thanks for your help

Pattern Matching and Vision Builder 6.0

Hi,
When I select a ROI from an image to generate a pattern matching, Builder
saves it as a PNG file.
If I open this pattern in other application (Paint Shop Pro 7) to modified
it and save as a PNG file, after I can't open this file as a pattern into
Builder, because it is considered as a not valid PNG file.
I have tested this case in LabView 6.i and this problem doesn't appear.
Any solution? Thanks.

When the template is first saved in Vision Builder, pattern matching information is stored in the header of the PNG file. This information lets LabVIEW and Vision Builder know how the template was learned. Paint Shop Pro does not keep this information in the file whenever it is saved so Vision Builder will not recognize it as a valid pattern matching template.

Labview 7.0 is compatable with Labview Imaq6.1 , vision builder 6.0 and Imaq run time engine 6.0.

Sir,
My system is PXI 8174 and i an using NI 1411 card for my application. I want to know the compatability of the softwares. Whether Labview 7 is compatable with Labview Imaq 6.1 , vision builder 6.0 and Imaq run time engine 6.0.

Hi,
Assuming you meant IMAQ Vision 6.1 instead of IMAC 6.1, this software was intended to run on LabVIEW 5.1, 6.0, and 6.1. I have heard of it being used with LabVIEW 7 on occasion, so it may be possible to make it work, but this has not been tested and is not officially supported. Vision Builder 6.0 should run; however, it was developed long before LabVIEW 7.x and will not generated code for LabVIEW 7.0 and later. The Vision RTE version should correspond to the version of Vision you are using. For instance, if the program was developed with Vision 6.1, the computer should have the Vision 6.1 RTE installed. With this being said, if you plan to use LabVIEW 7, I recommend updating your other software.

Vision Builder AI Vision Assistant issue with smart camera contrast

I am using a NI 1776C smart camera with Vision Builder AI 2011. The contrast is pictures in different from automated mode and running on the PC. After using vision assisant to process an image (erode, color threshold, lookup), when I run this script from the pc I get a totally different contrast then when I save the script to the smart camera and run in auto mode. Not sure why this is happnening.

Did you change any of the camera settings in MAX when testing on the PC? Any change in lighting between the two? Would you post sample images please?

Problem with Vision Builder and LabView: Error -1074395995, File not found

I have created an inspection with Vision Builder AI 2009 SP1. In it I load some pictures from the HDD and run some checks over it. It works fine. Then I have migrated it to LabView 2010, I get a message that the migration is successfull, but when I run the VI on LabView I get a fail status. I have been checking my program and I have found and error when I try to load the picture from file: Error -1074395995 occurred at IMAQ ReadImageAndVisionInfo
Possible reason(s): IMAQ Vision: File not found.
But I am not sure which file it refers to. At first I thought it was the picture I wanted to load, but I have checked the path and it is correct, so maybe it refers to another thing. What puzzles me most is that it works perfectly on Vision Builder and I have changed nothing in LabView, maybe it is a problem with the migration. Any clues?

Here's a screenshot of what I'm talking about. Put a break point here and see what the path is and compare that with what Vision Builder AI is using (described where to find this in the previous post). You could find where this global is used to make debugging easier.
Hope this helps,
Brad

How can I see the current script file name in Vision Builder

I would like to not have to remember which script file I have open. Is that displayed somewhere?

Brian,
I have been looking over Vision Builder 6.1, and from what I can tell, the name of the file that you are working on is not displayed on the screen, and there does not appear to be a way to get it to display there.
This seems like a very worthwhile feature to add, and I definitely agree that it would be useful. You may want to consider filing a Product Suggestion by using the Product Suggestion Center (PSC) that is linked below:

Hi Shada this can happen if you are including additional installers to your installer for example DAQmx. When you are doing this the installer has to include other files like MAX (Measuremente and Automation Explorer). Probably when you installed Vision Builder it updated MAX, so when your installer is trying to Include MAX, its asking for the source where it was installed in your computer in this case Vision Builder.
Here you can cache the information so its not asked again, or you can download a newer version fo DAQmx, so it will update MAX and change de dependecy.

I'm using Flash Builder 4.7 for a pure flash project (ie, no mxml) & all my graphics objects are in a swc that was exported from an FLA.
I've made some progress with that issue. If I explicitly assign the scale9Grid dimensions in the code, it seems to work:
obj.scale9Grid = new Rectangle(x,y,w,h)
...but having to do that is a real productivity killer. Would be nice to use the 9-slice guide setting in the FLA

Speeding up LabVIEW scripts generated by IMAQ Vision Builder

Hi,
I am an experienced c++ software developer, I have mainly used Microsoft's Visual Studio for development. Now, I am developing a real time application using LabView and IMAQ Vision Builder. The LabView application I developed calls a script that was generated by IMAQ vision builder...the application works, but it is too slow for the processing I need to do. In C++ I wouldn't have any trouble speeding the application up, but I am still learning how labview handles threads etc. Does anyone have any ideas?

Your question is very difficult to answer. Without knowing anything about the processing you are doing, I can't suggest anything to increase the speed.
Vision Builder does not produce the most efficient code possible. It is likely that the algorithm could be improved, but this really depends on what you are doing. It is also possible that your acquisition could be what is slowing you down, especially if you are using Snap.
Perhaps if you post the code generated by Vision Builder it will be possible to help you more.
