• It has no option in Vision Assistant block to close the session classification! (How to fix 1074396030 error?)

  I use Vision Acquisition blok, then assistant block vision.

  These blocks are in while loop.

  Once the vision outputs help block class for the next iteration:

  ERROR: There are too many sessions open classification. You must close a session before you can open another.

  I know there are block to eliminate the classifier, but do not know where to connect!

  The only option you have without upgrading is to right click on the Express VI and select 'open the front panel. The Express VI then passes to a standard Sub - VI that you can edit and modify the code to close the session if needed.

  The disadvantage of this approach is that by doing this, we have broken the link between the Express VI and the Vision Assistant, which means that you can not change the algorithm developed in the Vision Assistant more you.

• A question about 'value spots' in the Vision Assistant of NOR

  Hello, all,.

  I am a new learner or vision.

  When I use 'mark set' in the Vision Assistant of NOR. It works well. for example

  

  (The image above is the example in the Vision Assistant of NOR, please see help > Assistant Solution > Inspection of dental floss)

  However, when I put the program NI Vision Assistant to create a Labview VI program. (Tools > create a LabVIEW VI), then run the VI, it no longer works.

  

  The result of the system of coordinates outside is always like that.

  

  I can't find where is the error. I tried a few other examples in the Vision Assistant of NOR. If the command "set mark" is used in the program in the Vision Assistant of NOR. then create the LabVIEW VI.

  The problem still occurs.

  I hope some man experienced in NI Vision could help me.

  Thank you.

  Hi all

  This problem has been reported under Corrective Action Request (CAR) 441410 and has since been fixed in 2014 of VDM. I highly recommend upgrading to the latest version here: www.ni.com/download/vision-development-module-2014-f1/4971/en/ because it contains other patches. If you are unable to do so, I have attached the patched file, you need to change. Replace the following file (assuming that the default installation location): \National Instruments\LabVIEW 2013\vi.lib\vision\Vision Utils.llb Assistant with the version I have attached here, and that should solve the problem you see with NaN values of reference in the VG of the generated code.

  Kind regards

• Vision Assistant - not found .bin

  I would try here first before raising a support of thought gives the floor just in case someone has met before.

  Current running Win7 64 bit and LV 2013 SP1 (via 2014 DS SP1), with the development of Vision system installed. I have a range of fully powered Vision and can use the low level of Vision to my heart's content...

  However, I can't run Vision Assistant. Passing it to the Vision Assistant of the palette, I get the following two errors:

  

  

  I am also unable to open instances Vision Assistant previously configured in another code, even if no error is returned - the VA just does not work.

  I also have LV 2012 SP1 installed (including older versions) and now get the same error with it. I have not tried to use GOING because I went to LV 2013 several months ago.

  Has anyone encountered this before?

  I'm just trying to Repair Wizard 2013 Vision, which I'd like to think will fix it, but we'll see it. I'll let you know when 117 all required components are also repair finished

  Solve the repair.

  Unfortunately, this involved repair of components for 2013, 2012, 2011, 2010... but still, at least, I put my feet for a little while as it ended.

  Will mark as resolved in case someone else has the same problem.

• vision assistant problem

  Hi all

  I use my Vision assistant (2015, 64 bit, build 20150612021331) for the batch of treatment on several images in the browser. Ok.

  But for that matter, as he returned after the batch script to change by doubling (copy - paste) a bunch of "VIbox"... randomly.

  This bug reproduces very well on another PC too.

  Any hint?

  This bug has been fixed in Vision Development Module 2015 SP1 (CAR 567565).

  Please consider upgrading to this version.

• Different methods to find a form of rectangle Center and rotation in vision assistant

  Hi This is my first shot at the machine vision and Vision Assistant tool. I am trying to find a rectangle shape in an image and determine its Center and rotation around the Center. I started with this image:

  

  and I increased saturation and contrast to make a clearer target area:

  

  I am interested in the main red rectangle turned about 5 degrees to the right. For me, it seems that there is enough contrast edges, but quickly, I tried some of the edge (including the rake) detection and pattern matching algorithms and I don't get any useful results. Maybe it's the white lines don't interfere. I tried to extract just the plan of the red color but as white also contains red these lines always appear.

  I'm hoping to get some ideas for different approaches get precisely the Center and the rotation of this part, as well as the guidance you need to succeed. Thanks for the tips!

  I would try to extract the rectangle using color thresholding.  Analysis of particles of use on the rectangular blob and you should be able to get a rotation value.

• Vision Assistant has theAlgorithms.Resample feature

  I'm just not see it, or is there no way to resize (Resample) an image in Vision Assistant?

  It seems to me that the resizing of an image is one of the simplest function of image processing.

  I'm used to having to open images in MS Paint to resize, and then reoppen in the Vision Assistant.

  I created a VI resampling that works. But I just thought that it would be part of the core functionality.

  Yes, the function of resampling in Vision Assistant is in the first tab (processing of functions: Image). Select the step of geometry, and Resampling.

  Hi, would you please tell me what can I do with this PIN 'Image In "? It is purple

  I tried a lot of experience, but the vision assistant insist to grab me something to this 'Image In' purple

  I tried to create the path of file (green color), I gave him the path, but it did not work without "the image in.

  I am very new to the vision, it is perhaps a trivial question, but the help file didn't help me a lot.

  Thanks for your help.

  That's what you want

• Advancing the Straight Edge configuration in the Vision Assistant

  Hello world

  I used the function advance Straight Edge with Vision Assistant who I little understand but this is not enough for what I'm trying to achieve. I tried to find some info on the underlying theory, but the only thing I found is the help document for it, which provides details on the different variables only.

  Could you please tell me where I could find a good source of information on edge configurations right ahead?

  Thank you  

  Take a look at the NIVisionConcepts.chm you could find under ...\National Instruments\Vision\Documentation.

• Characteristics of vision assistant

  I was wondering if someone could tell me how to change an image´s brightness, contrast and histogram with vision assistant. I want to do this, in order to normalize the image and reduce the impact of the light on the image. I m of the system development will always illuminating, but I Don t want to get the results to change so dramatically with just a little change in illumination.

  Can someone help me please?

  Thanks in advance!

  There is a direct function under image - brightness.  You can adjust the brightness, contrast and gamma. If you want to go check dynamic table of choice

• Using the thresholds the in Vision Assistant Image calibration

  

  I would like to form images of calibration with some images of 1280 x 720 of grids that I take with a fisheye lens. Usually, when I raise Calibration training Vision Assistant interface, I have some tools really powerful local thresholding as in the screenshot above.

  But with images that I put in now, I'm threshold options that aren't really my needs. These are shown in the screenshot below. Is it possible to manually choose the local threshold options?

  

  Hello

  You got this window because it seems that you have a 32 bit image instead of an image of grayscale 16 or 8-bit.

  Convert your image into 8-bit, and you'll have the threshold parameters you need.

  Hope this helps

• Detect dirt on a picture of the camera with Vision Assistant

  Hello

  I want to test a camerachip cleanliness.

  I tried to make a detector of dirt for a camera with Vision Assistant 2011 SP1 image.

  I modified the cell analysis of the Solution Wizard.

  My Vision Script is not able to detect any dirt pirate on the camera Image.

  Maybe you tips to optimize my other scrip alternative.

  You can use "Equalize IMAQ" (could be found in the service Table of the Vision Assistant research) right after you open the image to spread the histogramm on any bit depth.

• How can I change the sequence of pictures, that I imported into Vision Assistant?

  Hello

  I have several issues of images I shot a framegrabber. Each has between 300-500 images .bmp are named 0, 1, 2, 3,..., 365.  The problem is that when I use Vision Assistant to open the pictures, it opens in out of use.  Ex: 1, 10, 100, 101, 102,..., 11, 110, 111,..., 12, 120, 121,...

  What is even more frustrating, is that he doesn't seem to be a way to rearrange the pictures, or I don't think I want to spend the time to do for 16 folders of images, with that I work.

  Thoughts... Ideas?

  In this case, it is best to name the images using 3 numbers and fill with zeros on the left.

  It would be pretty easy to write a quick vi who reads all the files in a directory.  For each file, it would remove the old number and replace it with three-digit version.  If the number is less than 100, it can rename the file automatically.

  I can't imagine other ways to solve your problem.

• Make an adjustment in line with the Vision Assistant for a polynomial function?

  Hello

  I have the following problem: I have a laser beam which a (non-linear) line on a wall. For this line, I need to know (exactly) mathematical

  function. That's why I can get a picture of the line, but I don't know how I can extract the mathematical function with a line fit for example. If I could "convert."

  the line at points that I would use the line fit function to LabView that should work without problem.

  Is there a way to solve the problem with vision assistant or... ?
