Count pixels labview vision 2013

hi
i want to determined percentage of pixels in a region, like function count pixcels in NI Vision Builder AI but in labview vision 2013

Brad, thanks for the response. I don't have access to the code anymore, I was more just curious about it. One of my old coworkers has actualy been in contact with me recently because he's the one who inherited my code. I had to walk him through how I implemented the VBAI code in to the main application because he couldn't just change a few setting inputs. It was more of just a inconvenience.
I guess my suggestion for the future would be for an option to output the VBAI code as LabVIEW code without all of the subVI hierarchy for those who are used to just using the IMAQ VIs. Just a linear set of code that goes from the start to fnish of the VBAI diagram that I could manipulate the way I want would be nice.

Count number pixcel labview vision 2013

hi gays
i need your help i want to count number of pixel with template in labview vison 2013
thanks
Solved!
Go to Solution.

Try the VI IMAQ Count Objects 2 in the Vision And Motion>Machine Vision>Count and Measure Objects palette.
If that does not do exactly what you want, you can still choose to migrate the VBAI inspection to LabVIEW (Tools>>Migrate Inspection to LabVIEW from VBAI) and look at the code generated. It will produce exactly the same results as in VBAI. The only thing is that the code generated is complex.
Hope this helps.

For MS Visio (any version) only the appropriate version of Acrobat *PRO* provides PDFMaker for Visio.
For Visio 2013 specifically you must have Acrobat XI Pro (updated to at least 11.0.1).

VBAI vs LabView/Vision?

I am designing a machine vision system that will use 16 GigE cameras, run on a dedicated PC, and will use standard edge and blob tools to perform a fairly routine set of inspection tasks. I will not need to code any new special-purpose image algorithms.
Because of the large number of cameras, I am interested in using parallel processes/threads as much as possible.
Also, I need to trigger inspections via Ethernet/IP from a Allen Bradley/Rockwell PLC.
Would there be any obvious advantages to using the Labview Vision Development Module rather than VBAI?

Here are some things to consider (in addition to what Christophe said).
1. You had asked about 32 vs. 64 bit OS..even if you're running a 32-bit application, I would always recommend a 64-bit OS. This allows multiple 32-bit applications to each have up to ~4GB of memory, and if you're talking about 16 instances of VBAI running, they can each get up to this limit instead of on a 32-bit OS being limited to the total memory available being 4GB shared between all applications.
2. Because VBAI only allows 1 instance to run the Ethernet/IP Server, you could use LabVIEW to do the communication over Ethernet/IP and manage triggering/acquiring images in parallel and then use the VBAI API to send the images to the VBAI engines with a set image variable call so the VBAI only has to process the image and send the results back to your LV program. I really liked Christophe's idea of using a network trigger that the PLC controls, but I don't know if your cameras support network triggers or if your PLC would support sending a action command to trigger them...maybe the PLC can just trigger them directly with I/O lines...I assume this isn't an option since you're wanting to use Ethernet/IP to tell another application when to trigger them.
3. If all your inspections are exactly the same (except for which camera they use), VBAI unfortunately has a restriction that only one engine can open an inspection at a time, so you'd have to make 16 copies of the same inspection and have each VBAI instance load a unique copy of the same inspection.
4. If this is the case (all your processing is the same), and the inspection is straight forward, I think using LabVIEW to run everything in parallel with a rentrant VI that does the acquisition and vision algorithm might be the simpliest and fastest approach, but it might take longer to develop the code.
Hope this helps give you some more ideas, and let us know if you have more follow-up questions.

Labview Vision Assistant Histogramm Problem

Good Morning,
i sadly with the Vision Package from Labview. I want to load a picture and interpretation a detail of the picture with black, white and grayvalve. This can i make with the Vision Assistant feature Histogramm. When i build it (the VI with Vision Assistant) comes nothing to the output Histogramm. I have checked the output line Histogramm, but nothing goes out of this.What are my failure?
Thanks a Lot
german translation:
Hallo zusammen,
ich bin leider noch nicht richtig mit dem Vision Paket vertraut. Ich möchte die Schwarz, Weiß und Grauwerte eines Bildausschnittes auslesen und diese auswerten können. Dank des Vision Assistant, kann ich dies per Mausklicks erzeugen, jedoch erhalte ich am Ende des Vis keine Daten. Selbst wenn ich die Quelle verbinde und ein Anzeigeelement hinzufüge, kommt hinten nichts raus. Was ist mein Fehler?
Vielen Dank

Labview VISION + webcam + find pattern

Hi all,
I'm making a job with pattern recognition. Unfortunately, I'm doing a first steps and don't understand everything.
I found a video regarding of this question > http://www.youtube.com/watch?v=trgCbKZXyUE - it's what I want to build and extend it then.
The diagram is finished as on the video, but I cannot catch and follow the necessary pattern. It's showing all the current image instead of requested object.
I think it's not a big issue to find out the problem, but I don't have enough skills to locate it.
So, please, if you can, correct the diagram, which you can find in attachment and then I can go on with my goal.
Thank you in advance.
Regards,
Michael

Labview vision - while loop + image + shiftregister = 2 times same image.

Well I got this problem here at home.
I've this .vi
I've labview 8.6 + labview vision module + labview vision module for usb webcams.
Well this .vi is pretty simple but it gives me some strange results...
When I run this I get the same image on "image1" and "image2"... while in fact "image2" should be the "image1" of the last loop. This should be visible when you set the sleep time of the loop higher. Now the problem is is that on my frontpanel "image1" and "image2" are ALWAYS equal... But then when I click on the two wires of "image2" and "image1" then the difference is visible. But on the frontpanel "image1" equals "image2"...
A couple of weeks ago when I first was testing with labview + vision on my university there was a visible difference between the two images. This was with the same webcam and software.
Anyone got an idea how this is possible?

How can I determine the liquid level in a bottle (LabView Vision)?

How can I determine the liquid level in a bottle (LabView Vision)? Does anybody have an example code? The task is, that if liqid level is between two predetermined level, the program writes, that it is correct else it writes incorrect. Thank you.

here is a little play with your bad picture:
used only the small field of interest (here a guess) ,
used only the red channel ( takes out most of the light reflection)
grey scale, 3x(blurr, median filter) , played with contrast -gamma - saturation
now you need to add the edge detection and some sort of scale.

Labview myRIO 2013 stopped working after product activation, system vi files not found, (Hex 0x8004041F)

Hello,
My Labview myRIO 2013 had been working while it was in its evaluation period. Recently, I activated Labview 2013 with a 6-month activation code. Now, if I try and create the standard myRIO tutorial starting project, when it tries to load "Main.vi", it stops and says:
Loading:
<vilib>:\myRio\Common\Instrument Driver Framework\myRio v1.0\myRIO v1.0 Reset FPGA.vi
Searching:
C:\Prog... \LabVIEW 2013\Targets\instr.lib
and it pops up a file browser dialog box.
I found the file in C:\Program Files (x86)\LabVIEW 2013\vi.lib\... , so I manually added that path to Labview's VI search paths, closed everything, and re-opened Main.vi .
After doing so, I can get Main.vi to load and display properly after taking it's dear sweet time to recursively search vi.lib\* for each vi file, but if I try to run it, I get a crytic and un-googlable error message:
NI System Configuration: (Hex 0x8004041F) The operation failed because of missing dependency items.
It gives no further information on what dependency items are missing.
Why did Labview work before? It had no problem finding dependency vi files before I activated the product. The "Getting Started" demo apps still work fine, reading accelerometer data and controlling the led's on the myRIO, so I know the myRIO itself is working, along with the USB connection.
One final note, the "Labview 2013 Real-Time Module" has not been activated. Could that be the problem?

Hi Mike,
That Hex error message only occured if I tried to run the VI by clicking on the little "run" button at the top left. Main.vi would open just fine, after locating all of the vi files.
So I seemed to have fixed my particular issue (for now)... I had noticed after I typed in my activation code that Labview was telling me that I had additional evaluation time available to me. I had been ignoring those messages because, 1. I had an activation code and therefore didn't need additional evaluation time, and 2. Labview was opening and appeared to be running just fine, whereas before I applied the activation code, Labview would not even start. So, towards the end of my adventure after I felt I had applied my forehead to my keyboard a sufficient amount, I finally said "Ok whatever, give me additional evaluation time", and voila, all of my previous issues disappeared. Vi files were being found normally as before, and I was no longer getting that Hex error when I hit the run button.
I'm not sure exactly what components I'm getting "additional evaluation time" for, but whatever component it is, it seems to have fixed my problems.
So anyway, thanks for the support! Hopefully this fixes my problem for good

Labview Vision Assist IDS camera

I ordered a camera from IDS, the 3360CP. This is for my thesis. IDS has there own VI's for labview for the camera.
The problem is that the image which is generated with those VI's is not compatible with the
vision assistant module in labview 2013. I'm looking for a way to convert the image.
I included the VI. If it doesn't open propperly the flowwing link can be used to install the labview VI on your pc.

They can be found under program files/IDS/uEye/otherdrivers/labview.

The IDS cameras that require use of their SDK (the VIs they supply) are not directly compatible with IMAQdx, and hence, not suitable as image acquisition devices for use in Vision Assistant, and Vision Builder for Automated Inspection.
You will need to incorporate the IDS VIs into your pipeline in a way that makes the acquired image available to the script. Most likely, this would be by writing the image to disk, and then signaling the script that the image is ready. If you need fast frame rates, and are not able to do everything in pure labview, I recommend looking at a different camera.

Creating a digital counter in labview

Currently using a proximity switch connected to an SCC-DIO1 to read pulses from an encoder to develop an RPM measurement ( and angular velocity). How do I convert my digital pulse into a true numeric count per minute (or millisecond)? I'm able to detect the pulse from the module in labVIEW but I'm unclear on how to count the pulses per minute. Currently using labVIEW 7.1.

If all you're doing is counting pulses, you'd actually be better off
using the counters on your DAQ card. They automatically track the
number of pulses and can give other info like frequency. Look in the
Examples for Counter VIs to show you how to use them. There's a pretty
good one named "Getting Started Counter.vi".
If you're set on just using a digital line, the attached image shows
how to setup a basic 32 bit counter. (but I still suggest you have a
look at using the Counters)

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.
