Vision Builder for Automated Inspection and communication to external programs

I want to use Vision Builder for Automated Inspection in my application to do the vision tasks. However, the vision task
is only a part of the total application. Like for example, the application starts by reading the input of a barcode scanner.
Based on the value of the barcode, the proper program should be loaded in Vision Builder for AI. I was thinking about
using the .NET environment to build the application and call Vision Builder for AI from out of there. Is this possible? If
not, are there other solutions?
Thanks!
Bert Christiaens

Hi Bert,
Vision Builder includes a Product Selection functionality that allows to automatically change an inspection based on the result of a step. For example, if the interface to the barcode scanner is Serial or TCP, you can use the corresponding step in Vision Builder to read the barcode, and based on the result select the appropriate inspection.
That is if you want to stay within the Vision Builder environment.
If your application is already written in .NET and you need to add Vision to it, then as mentioned in the post above, Vision Builder has a programmatic API that you can call from .NET (example located here:
C:\Program Files (x86)\National Instruments\Vision Builder AI 2011\API Examples\dotNET Examples
The API allows to programmatically load an inspection, run it and get results, close it, etc. From the information you're providing, it seems like it might be the option that is the most appropriate to your application.
Best regards,
Christophe

Vision Builder for Automated Inspection: Image randomly appears upside down

Hi everyone,
I seem to be having a rather unusual problem here. I'm using an IDS UI-6280 camera to simply take a picture and log it to a file every minute. However, about 50% of the times when I start VBAI, the image appears upside down. The only solution I have found so far is to close VBAI and start it again. It usually takes a couple of tries before the image turn back up again, and then it's okay for the next couple of times I open VBAI. I have found no clues at all as to what could be causing this. Has anyone experienced something like this before?
Clarification:
- Once VBAI is running, the image does not flip randomly. If the first image is upside down, so are all the subsequent images. If the first image is upright, so are all the subsequent images. The flipping only seems to happen when I open VBAI.
- The flipping only seems to happen when I use VBAI. Using the IDS software always gives an upright image.
- There is about a 50-50 distribution between upside down and upright images. However, there seems to be some pattern in when the flipping occurs. I just opened and closed VBAI 10 times, the upside down and upright state occured in an order like this (x=upside down, 0=upright): x0xxx00000
Any help or insights would be greatly appreciated!

1. Does the camera have an attribute for flipping it? If it does, the camera may not handle this attribute well when VBAI sets this attribute in conjunction with the other attributes as fast as VBAI can when it is initializing the camera. Most cameras respond when they are done and ready for the next attribute to be set, but some cameras respond before the attribute is done being set and can get in a messed up state if another attribute is set too quickly. You could try using the Read/Write Attribute Step in VBAI to manually set the flip attribute off before you acquire (make sure to set the flag to always set this attribute even if the current value is the same as what it will set to).
2. If you acquire an image in MAX, is it upside down? Try Clicking on the camera in MAX, acquire, click to another camera or to another device (this will release the resources for the camera), click back on camera again in MAX and acquire again. Repeat this several times and see if you have the same flipping behavior as in VBAI.
3. If you create a new inspection with just an acquisition step, does it still happen? Make sure not to change any of the default attributes for this test case. This will ensure the VBAI step uses the same settings you would see in MAX.
4. What if you try using Snap Shot mode in the acquisition step instead of Immediate mode.
Hope this helps,
Brad

Hello HeartShield,
If you double-click on each missing subVI error, you should be taken to a location on the block diagram where a question mark is holding the place of the missing subVI. Right-click on the question mark, select Replace, and then navigate through the palettes until you find the VI. Clicking on the VI in the palette completes the replace operation for that question mark. After repeating this procedure for each missing subVI error, you will need to save your VI.

Visual studio community with external program - license

Hello. I have a question about using Visual Studio Community. Are the license allows to use Visual Studio community to only write (and testing) an application/game and then building it using external program for example Eclipse or Xcode for commercial purposes?
I create for Android/IOS systems, and working in small 2 persons team.
Sorry for my English, thanks.

Can you give me an email from Microsoft licensing specialist?
@ Metoby，
Sorry for that I also have no email of the license memebers.
In addition, you know that this forum is to discuss the English language issue, so I provide the license call for the English support.
If you want to use other language, one idea is that you could post this issue to your local country if it also have the MSDN site.
Maybe this link would be helpful for you:

How can an add-on like Firesheep access and execute an external program like Winpcap? Is that a security flaw in Firefox?

I have been reading about the Firesheep add-on that allows the user to hijack sessions of users on the network by stealing the cookie. I understand that to prevent any application from stealing the cookie, the cookie should not be passed by the site without SSL. However, my understanding of how Firesheep works is that it interfaces with Winpcap (a network sniffer). So my question is "How can an add-on execute an external program or operating system command like Winpcap?" Can any add-on do this and should I be extremely afraid of downloading any add-on because of the potential that it could have complete access to my system?

Hi Scott-L.
You asked a very good question and it turns out you're right.
However, one must be aware that download an Addon on another website that Mozilla may be dangerous. Indeed, the Addons found on the Addon Center are checked (roughly).
In addition, Firefox includes a blacklist that blocks addons identified as malicious.
More information here: [http://www.computerworld.com/s/article/9193420/Mozilla_No_kill_switch_for_Firesheep_add_on?taxonomyId=17&pageNumber=1]

TFS 2013 Build for PL/SQL and Oracle Projects

Hi,
We use TFS Build with SQL Server Projects.
We also have PL/SQL projects .We are using MSSCCI to check in and check out files. Is there anyway we can use TFSbuild for these projects( [PL/SQL]/Oracle) too ?
Thank you.
Su

Hi Su,
Thanks for your post.
How do you manually build your PL/SQL/Oracle projects?
TFS Build invoke MSBuild command to build project/solution on build agent machine by default. If these projects can be built using MSBuild command line manually, then we can use TFS Build(default build process template) to build these projects.
If these projects need be built using another complier, and this compiler support run the command line to invoke it, so you can add the InvokeProcess activity(execute the command line) to invoke this compiler to build these projects in build process template,
then create build definition using this customized build process template.

How can i compare two color images in vision builder for AI?

What i want to do is to compare two images. I have a base color image that represents the desired colors and tones. I have another image to be compared to the base image. What i want to do is to compare this two images to know how close they are regarding contents of color and tones. In other words, i want to know how close is image 2 to image 1 (base sample)....
I would like to know how to get the content of certain colors in an image and then compare this values with the same values from another image.
For example..i have two sheets of paper that contain various mixed colors...i want to know the amount of green, red an blue in each image and then comapre this values.
What i want to do is to compare difer
ent samples of fabrics. this fabrics must be of a specified color...but due to the process they may vary in tone or even color...so i want to compare this fabrics to a amster sample to see how close they are in color and tone..
Anything would help since i dont have experience in this type of comparisons...thanks

VBAI allows you to work with grayscale images only. You can acquire an image, use the vision assistant to convert it grayscale by extracting the luminance plane (or any of the other color planes) and then analyze the resulting grayscale image. To do what you are talking about, though, it would really be better to get Vision for labview. You could then take color images, compare color plains, use statistical functions to determine average color values, and so on.

Vision Builder AI import inspection error "Invalid Inspection file selected."

I am attempting to import an inspection into another and get an error
Open Inspection:
-Invalid inspection file selected
I have been able to successfully import other inspections in the past but for some unknown reason these two inspections that I am trying to merge are having trouble..
Thank you
Pete

Hi Pete,
-Is it possible to upload the inspection file for which you are getting this error?
-Can you explain more on this inspection file? What it does?
-From where did you get this or you created this file? If so, from what version of VBAI it is created and what version you are using?
Thanks

New Build for CS4, CS5, and upgrade

Hardware problems, and I have to upgrade even though I can't afford it. I only need to run CS4, but I want to try to keep an easy upgrade path to MPE and more RAM. I think I can run CS5 on this rig for SD; do you agree?
I've been following the various discussions (including the latest "CS4" and "Budget build" and I have searched this forum for each component. But this is complex and a moving target. so before I spin my wheels more, what do you think? My decision point for several things has been what is cheapest without totally ignoring quality. Several of these components appear to have mail in rebates that are not reflected in the price. Total is about $1400. (All newegg.)
I did forget to swap a velociraptor system drive; adds about a $100. From what I have read here, I can do without additional CPU cooling for now?

>info on the actual building
I didn't post any pictures... so a couple of thoughts
1st is I am OK with my mid-tower, but a full tower would be better so all the various cables wouldn't be so cramped
2nd is that I mounted the CPU cooler after the motherboard was in and ram installed... this was in case there was a problem with the non-Intel cooler getting the way of ram install, which turned out not to be a problem with the brand/model I picked... and it was VERY nice that there was a cut-out in the motherboard mounting area to allow me full access to the back side of the motherboard to mount the cooler
Actually, a 3rd thought is that I added 2 side fans right over the CPU and nVidia card, so have plenty of cooling even though I do not overclock

Is there a way to bypass the first two inspection block after first cycle in Vision builder AI?

I want to inspect the C-C of a matrix of holes (holes side by side). But when I do re-cycle the routine, the hole #'s change location (not in same place twice) and the my C-C are all not side by side and all over the place. For example, diaganal 4 holes away, etc...

laj,
I'm not sure that I completely understand the question that you are asking in your post. You may want to repost your question with some additional information and explanation to allow this forum to help you more effectively.
As for the question that you posed in the title of your email, can you bypass the first two steps of your Vision Builder for Automated Inspection (VBAI) script? The answer is unfortunately no. VBAI is designed to repeatedly run through the same script and does not allow only a portion of the script to run.
If you need more control over your application than VBAI can provide, you may need to move a programming language like LabVIEW, which will allow for lower level decision making.
Please post a follow up if you have any additio
nal information you would like to add, or have additional questions.

Run-time License for Vision builder

HI
I have created a VBAI file for my inspection in, but now I want to transfer the inspection LabVIEW and build an exe to run the application.
Now for running that application do I require a NI Vision Builder for Automated Inspection Run-Time License or a NI Vision Development Module Run-Time License.
Thanks,

Instead of migrating to LabVIEW, you might want to consider automating Vision Builder from LabVIEW and running your inspection by using the VBAI API.
Check out the examples located here: C:\Program Files (x86)\National Instruments\Vision Builder AI 2013\API Examples\LabVIEW Examples.
The VBAI API allows to start a VBAI engine, open and run an inspection and retrieve images and results for each step.
When using this method, if you're running the LabVIEW program on the same machine VBAI is installed, you do not need to purchase the VBAI runtime, neither the Vision Development Module Runtime (unless you wish to process further the image returned by VBAI.
If you need to deploy that LabVIEW application on a different machine, then you'll need to purchase a VBAI Runtime license.
If you choose instead to migrate the inspection to LabVIEW, then you will need to purchase a full license of Vision Development module for your development machine (the code generated uses Vision Development Module VIs).
If you choose to build the resulting code into a LabVIEW application and deploy it on a different machine, you will need a Vision Development Module Runtime License for the deployment machine (but not a VBAI license).
Migrating the code to LabVIEW is recommended only in cases where you need to modify the code generated by VBAI. The code generated is indeed a lot more complex than using the VBAI API that I described in the first option.
Hope this helps.
Best regards,
Christophe
