• Error 1074395720 has occurred to IMAQ find circular Edge 3 IMAQ Vision: invalid KING.

  Hello

  I am writing a program to adapt to a circle of an image (from the avi), but when running the IMAQ find circular edge v3.vi I get the error message:

  "Error 1074395720 occurred at IMAQ find circular Edge 3.

  Possible reasons

  IMAQ Vision: Invalid KING. "

  I use the vi KING of construct IMAQ to set the return on investment and I am sure that the KING output is in a format suitable for the discovery of the IMAQ circular edge v3 vi.

  I joined my program (Labview 2011)

  Any thoughts?

  Thank you very much

  Hi Rory,

  Welcome to the Forums of NOR.

  «IMAQ find circular Edge 3' expects a return on investment for type 'Ring'.» There are a number of functions in labVIEW for the conversion of the type of return on investment as "IMAQ convert the KING to ring. However, as the circular edge VI find JUST does not ring but bounding box and other details as well, there is a strange solution to this problem.

  Drop-down "IMAQ convert KING ring" and get the return on investment through. Drop-down and then "Convert ring to the KING" (Yes, really) and pass the output of who to "find the circular edge.

  It is circular, strange workaround, but it seems to force the type of return on investment to go to the ring and so works.

  Let me know if you have any other questions.

  Thank you very much

• Circular edge IMAQ find 3: result rounded

  Hello

  Can someone please explain to me the significance of the result "Roundness" of the circular edge IMAQ vi find 3?

  I know that the definitions of roundness like MCC, MIC and MZC.
  Is one of these related to this result?

  I get results ranging from 0.1 to over 8 on several images, but it is clear to me how resulting interpreter.

  Thank you for your ideas!

  Best regards

  Roundness or residual represents the least error square of the circle that is adjusted to the set of points. 0 for the perfect circle

• circular edge

  Hi all

  I use vision Builder AI 2012 and I have trouble finding the truncated right edge.

  The edge that I found isn't always the strongest one. Normally this isn't a problem (I'm looking for the first edge), but sometimes my program detects the edges that I don't want to see. I have played with all the settings, but the results are not always as I expect.

  Is it possible to specify the coordinates of the center of the circular edge? That would really solve my problem, but I can't find a setting that makes it.

  With sincere friendships.

  Tom

  You can try to use the step to detect objects that makes it easy on the threshold of the image to find objects (i.e. your circles), and then there's advanced filtering options to throw unwanted objects (only keep objects of circular... This is called the factor of circularity Heyward and the closer to 1, it's the more circular, it is, or filter the objects that are too small too large or touch your region of interest. This step can even return the diameter of the object. This step is used in this example I showed you to count the holes in the oil filter, but you can use it to get the position of the circle.

  Hope this helps,

• I can't change the discripter KING of the circular edge detection

  Hello

  I need to find the find of circle using the circular edge detection. Here, I need to change my KING. so I used the property Node display.

  But I can't change my KING.

  I've attached my VI file

  I understand that you want to change your return on investment... have you checked the link I provided in the previous post?
  -KING of the ways showing different coordinates, how you give their evolution?
  -simply by selecting the property KING will give nothing unless you draw something in the indicator of the image. For example, when you select the tool KING and draw something so the return on investment parameters will be passed to the property node.

• IMAQ vision function reference

  Hi all

  I'm new to Lab Windows/CVI and uses the library imaq vision.

  Could someone tell me where I can find the reference of function IMAQ Vision? I found a function reference manual at first--> National Instruments--> Vision--> Documentation. But all the functions described in this document are starting by img * (). I was looking for functions starting with imaq * ().

  I'm sorry that it might be a stupid question, but any help would be appreciated.

• How to download imaq vision

  I am a new user of labview and I wish to study this subject IMAQ vision. However, for the same thing, I have no idea as to how I can use it on LabView. Smoker I don't understand if I have to download additional software for IMAQ Vision work with LabView. Kindly advice me.

  Jean-Luc

  NOR-Vision and NOR-IMAQ are two different things. NOR-IMAQ is a set of drivers and software to acquire, view and save images of some devices. The supported devices are in the readme file. This software is free. NEITHER Vision is a software level. He did work with a wider variety of devices. It is not free.

  I think that it is best to call your local sales office OR that they would be better suited to help you, rather than this forum. We mainly answer technical questions here.

• IMAQ Vision: (Hex 0xBFF60403) copy unauthorized IMAQ Vision.

  Hi all

  I have a Labview program developed a few years ago by one of my students who use some images from a camera to do some analysis.

  It's the environment that was used:

  Windows Xp professional version 2002 Service Pack 2

  LabVIEW 7.1
  LabVIEW Run-time Engine 6.1 - 7, 0 - 7.1.1
  NOR-Imaq 3.1.0
  IMAQ vision 7.1.1
  NI-Visa 3.1
  NOR-488. 2 2.40

  NOR-IMAQ 3.1

  Application Builder 7.1

  Now, the PC crashed and I tried to restore all the software and VI.

  I got these (3) types of errors when I lounched the VI:

  1074396157 error occurred at WindShow IMAQ
  Unauthorized copy of IMAQ Vision.

  1074396157 error occurred at WindSize IMAQ
  Unauthorized copy of IMAQ Vision.

  1074396157 error occurred at WindMove IMAQ
  Unauthorized copy of IMAQ Vision.

  Possible reasons:

  IMAQ Vision: (Hex 0xBFF60403) copy unauthorized IMAQ Vision.

  I read that it is possible to overcome these types of errors lounched visionXXrte.exe, but I don't have on my PC.

  What can I do?

  Thank you for your help

  Hi all

  the problem has been resolved.

  It has been necessary run the NILM License Manager and activate the product of the Vision, which has been exceeded (I don't know why).

  So, thanks to all the world.

• Lost file "IMAQ Vision example Folder.vi"

  Hello world

  I was working with this file and I lost it. Now, I could not find or fix also I re - install all the modules of the vision, and many examples use this file to take the path of the image to work. Someone can help me trying to find the path and bring me the IMAQ Vision example Folder.vi

  Thank you for your cooperation,

  John

  Hi, thanks for your response, I did it and I don't know why, but did not work. I solve the problem using the IMAQ Vision AVI Folder.vi and change the block diagram and removal of some parts and then rename it as the vi that I lost. In this way, I solved the problem.

• bug in several functions of IMAQ vision mask

  Some functions IMAQ Vision bad work if you use the image source as the mask. I keep running into this bug in IMAQ Vision, Vision functions exhibit this behavior, and others do not. It is not documented in job descriptions. Even if it were, it would still be a bug. Example:

  1. create an image source U8 containing zeros and nonzero values.

  2. son of the image in the entry source and IMAQ mask entry quantify and return the value of % of the global report to see what percentage of pixels are different from zero.

  The answer is wrong. If you copy the image in a separate image first and distinct picture of wire in the input mask, you get the right answer. See attached VI for building

  

  See you soon,.

  -root

  If someone knows a way to return the number of pixels not dummies in an image without duplicating the image in memory, please post the method here so I can mark it as a solution. I find that using IMAQ getpixelvalue in a double loop is extremely slow, even with a shift as a counter register.

  Using the histogram IMAQ VI seems to work (with no mask image)-the first index of the returned histogram array is the number of zero pixel, so the sum of the table no less (or less area this) is the number of pixels non-null.  The VI has the same bug with the image of the mask (and I agree with you that document a bug does not correct!) but at least you can use for this problem.

• How to cut the lines to get the circular edge?

  

  

  What I'm asking is how do my lines have this circular edge like the inside of these lines... I'm sure that its some pathfinder tool where you put a circle on the top lines but I can't seem to find the right order to get this look... Any advice?  P.S. I'm still tweeking the colors and the others then... AND the largest circle is the one that I was trying to use to cut the lines...

  Combine your lines

  Draw a black circle on top (black will be your color to make invisible things)

  s

  Select both

  Transparency > make opacity mask, use these settings

  

  Note: there are 2 squares in the transparency palette.

  Left square highlighted (as shown above) - edit art

  Humble square highlight - modify the mask

• IMAQ Vision Image structure

  I currently grabbing an image, using my own equipment and windows messaging and do it in memory as a bitmap image.  How to copy this image in a structure Image IMAQ Vision.  I see other threads that the structure is the owner, but is it possible to copy the raw data in the structure of the Image.  The only way I can achieve this is to write in a BMP file, and then use the () imaqReadFile to read back in. It takes a lot of time, it would be much faster if I could copy from one location to another.

  You can use imaqArrayToImage(), but I've always found this difficult to use function.

  my favorite way is to create a new image of the right size using imaqCreateImage(), then get a pointer to the first pixel using imaqGetImageInfo() and fill pixels directly by copying the data in the buffer of the image. I already showed how to access pixels directly on this forum. You should pay attention to the size of your pixels and the format of the image (RGB, grey levels).
