11 years of labVIEW based Vision System development

Hi,
I am into desiging and development of Machine vision system and mostly using labVIEW. I am using labVIEW from 6.0. I have successfully deployed 27 Vision systems. Please Send me a private message if you are interested in hiring me.
I have no location preference.

Hi there!
Did you get hired yet? If not, I'm a recruiter with a small company (a think tank) in Los Angeles, CA. I'm actively seeking a LabVIEW Vision Systems Programmer with 4+ years of LabVIEW programming expereince and demonstrated knowledge of NI LabVIEW vision. Does this sound like your experience?
Please let me know!
Cheers,
Kate

Feedback on "Labview based Advanced Instrumentation Systems"

Should on add he book "Labview based Advanced Instrumentation Systems"
by Sumathi and Surekha to a collection of Labview Books? How would
you compare it "Labview for Everyone" by Travis and Kring?
Howard

Hi Howard,
Travis and Kring is a classic Labview book and always recommended. We have not really looked at the other book but after looking inside it looks like it some good applications and examples. It really depends on what you are looking for--for fundamental knowledge of LabView I would go for Travis and Kring. Hope this helps.

Vision system to look at a bubble level?

Would it be possible to use some type of NI vision system to view a bubble in a bubble type level and to somehow "measure" how far off the bubble is left or right?
This would be some type of system that would (somehow) set a table to a calibrated "known" level position. I'm not sure if this would be some type of gyroscope or another calbirated level, but we would have to start with a good solid calibrated level surface. We would then put a level to be tested and use a vision system to "view" the bubble to see how far off it is and report it as a % accuracy or uncertainty.
I'm not looking for Labview code, only if this can be done with some NI vision system. Is there a camera that can see the bubble and calculate some % of the bubble outside of the lines?
Seems like an odd application I know, but I'm just looking for input.

Alternative approach I'd use if space permits and tilt angle is within reason:
Use a digital protractor and then use vision tools for character recognition to read the display. If angle range is high, then use a fiducial and coordinate system to compensate for the angle so the characters can still be read.

EDIT: There are also inclinometers that have analog and digital ouputs/communications that would alleviate the need for vision entirely.

Where is original point of Z axis in a stereo vision system?

Hello, everyone
I use LabVIEW Stereo Vision module. After I calibrate my stereo vision system, I want to verify the accuracy of my system. I can get every point`s depth in my picture, but where is my original point of Z axis?
In the newest NI Vision Concepts Help, it is written that NI Vision renders 3D information with respect to the left rectified image such that the new optical center will be at (0, 0, Z) position. Is the original point of Z axis is on the CCD of left camera or the optical center of my left camera`s lens?
So anyone can help me ?

Hello,
I would say that the coordinate system origin is at the optical centre, that is the camera's projection centre.
So, yes, the optical centre of the left camera's lense. This seems most logical to me...

I want to buy NI cam for my machine vision system

Dear member
I need to buy a NI cam to use it in my machine vision system that is used to in recognition of screws head like in second figure
the problem is that my web cam is not able to produce high quality image
so I need no but NI cam high quality
I need only NI cam with USB cable, not a NI smart cam with processor
what is your suggestion please??
best regards

For your industrial machine vision application, you would be better off with an industrial protocol like the Gigabit Ethenet (GigE) or USB 3.0 cameras. You should have a look at Basler's Ace line of cameras (scroll down and have a look at the Gigabit Ethernet and USB 3.0 tabs).
Althought there are advantages to USB 2.0 (cost effectiveness, USB 2.0 ports available everywhere), it is still the least standardized and least popular camera bus considered. The one obstruction to the widespread adoption of USB 2.0 for vision applications is the lack of a hardware specification for video acquisition devices. Each vendor has to implement its own hardware and software design, which means that a special driver must be written to connect each USB 2.0 camera to each different software package. As a result, IEEE 1394 is much more prominent in vision applications. Also, most image acquisition drivers for USB 2.0 use utilities like DirectShow to acquire images into the PC. While these tools work well, they are a burden on the CPU. As a result, USB 2.0 image acquisition can be processor-intensive. Utilities like DirectShow also do not provide any type of interface for triggering or communication. Because of this, without a special driver, it is very difficult to synchronize USB cameras with each other or the rest of a system.
GigE Vision and USB 3.0 Vision are built to avoid this (by using GenICam) and are supported by National Instruments' Vision Acquisition Software. If you have to choose between GigE and USB 3.0, just remembe that GigE is good for longer cable lengths (100m v/s 8m for USB 3.0) and works well with multiple camera. Otherwise, USB 3.0 has better bandwidth (350MB/s v/s 125MB/s for GigE) and is plug and play (no extra power required).
Before you choose the camera, try to undestand what resolution and fps you need depending on your application, and then select the camera.
To get the right lens, you need to know the CCD size of the camera, and working distance and field of view of the object. Working Distance is the distance from the front of the lens to the object and Field of View (fov) is defined by the smallest rectangle of sides x and y which contains the object at the object plane. You need to use these to calculate the focal length and then choose the right lens.
Also, be sure to select the right lighting. Metaphase has some good products.
Wherever you are based, you should be able to find a local vendor for the camera, lens and lighting. Be sure to do the due diligence. You should, then, be able to get a good image for your application.
thank for your information share
is CCD size=pixel size?? what ccd mean ,is thier other type,what ccd advantage??
also
i have buy camera with specific focal length then if i add lens with 14 mm focal is the total length will default focal+lens focal (14)?
what is the effect of focal length and pixel size on images??

I think I activated LabVIEW on it a couple of time (3 or 4) and never got rejected byt he authentication server or a phone call from NI. I think that their authentication server is more there to make sure something isn't "out in the wild" rather than to enforce the 2 or 3 installations (whatever the license grants). I have NI Developer Suite installed on my work computer and my home laptop. I build and distribute the code that runs on "test" machines. NI Licensing really works well for me .
The license manager is smarter than that. Eventhough you installed the OS several times and the actual machine ID probably did change because of that, you did not completely change the machine itself, and the machine ID is based on several characteristics of your hardware and software installation. So the license server can detect if it is just a reinstalled machine or instead a completely different one.

Using Consumer Digital Camera for the Vision System

I am evaluating, if I can use a consumer digital camera for the vision system. I wanted to see if anybody out there have done that in past? The other question is, do the consumer camera manufacturers provide the driver software in order to retrive the images directly from the camera to the computer ?

I think your suggestion is right, using a firewire camera is much
straightforward. But some consumer cameras have advantages too because
of the very high resolution, especially the newer models of digital
still camera. If the cameras support PTP protocol, then I have a
LabVIEW driver for them. Check out more details at:

Is firefox 5.0 compatible with non-intel based mac systems?

I downloaded 5.o previously this year & it wouldn't work because after downloading I discovered that it would only work with Intel based Mac systems. Has this changed? I don't want to go thru the download process again if it won't work.
Thanks.

No. as of Firefox 4.0 and newer from Mozilla you need both OSX 10.5+ and Intel.
Either you can still use Firefox 3.6.18as you are using (3.6.19 will be coming in some 5 weeks) http://www.mozilla.com/en-US/firefox/all-older.html
Or use a third party version built for the old PPC.

Launch code targeted to compact vision system

Following the NI tutorial on "Easy Ways to Launch Code Targeted to the Real-Time Controller," I am attempting to use the 'System Exec.vi' with an assembled command line in a 'LabVIEW for Windows' program on the host such that I can skip the steps associated with opening LabVIEW on the real-time target and manually downloading the code I want to run on the real-time target.
As such, in the LabVIEW for Windows host program, I use the command line to feed into the 'system exec.vi' with the exact following syntax (including quotations):
"C:\Program Files\National Instruments\LabVIEW 7.1\LabVIEW.exe" -target 192.168.10.15 "C:\Program Files\National Instruments\ROTH LABVIEW\DAPC-NICC_71\RT_grab_images.vi"
I perform this st
ep just prior to calling by reference the 'RT_grab_images.vi' to acquire a set of images using the compact vision system and transfer these back to the host. However, I get an error 7, file not found (I am assuming it is the 'RT_grab_images.vi' file that is not found). If I have already manually downloaded the 'RT_grab_images.vi' (which negates the advantage of using 'system exec.vi' with the command line shown), everything works fine.
Can someone comment on this?
Thanks,
Don

Ok, this worked and from one of the other NI engineer (Michael Hoag), we discovered a way to programmatically execute this procedure using system exec.vi and a script file. For example, see the attached.
Below is more information from Michael if you have VI that you need to launch that has subVIs, and if you need to launch from other directories than c:\.
"Don,
Alright, with a little more persistance and work I think we now have a
working solution. I realized that the problem was that after copying the
VI over to the CVS, the VI was not in memory and was never "downloaded."
This means that all of the necessary subVIs (like all the standard LabVIEW
VIs from vi.lib) were never loaded onto the CVS and therefore the VI would
not execute when we used VI server, unless the VI had already been loaded
into the CVS' memory by targeting it.
To solve this problem, all we need to do is build a library (.llb) file for
our program that includes all subVIs, even those from vi.lib. This can be
done in LabVIEW, by going to the File menu and selecting Save With Options.
Make sure the "Include vi.lib files" option is checked and then create the
distribution. I have attached a new screenshot of my block diagram where
you can see that now I reference the main VI through the llb file (see the
path in the block diagram). In this case I placed it in the startup
folder, but that should not be a requirement. I also modified my script
file to take into account these changes.
I have rebooted the CVS several times to make sure nothing is in memory and
ran this new code. This appears to correct that last problem and should
get you moving forward with your application. Let me know how this goes
for you, and hopefully we have found a solution here.

"Don,
The error you are receiving when trying to call directory "C:\Program
Files\National Instruments\ROTH LABVIEW\DAPC-NICC_71" is definitely a
result of the DOS command prompt not linking the spaces and long
file/directory names. If you want to use that directory then you'll
probably have to figure out what the 8 character representation of those
files and directories are. For example if you want to get into C:\Program
Files\ then it will most likely be C:\Progra~1\. If you go to a DOS
command prompt (In windows go to Start >> Run and type in COMMAND), and
then type "dir /x" to display the directories, then the /x will have it
show the 8-character name for the directories and files.

NI LabVIEW Base Development System for Windows and NI CVS-1454

I have NI CVS-1454 and NI LabVIEW Base Development System for Windows (LabVIEW 8.5, no LabVIEW Real-Time Module and Vision Development Module). How can I build a LabView-program and run it on my CVS-1454?
Kirill Kostousov

Hi Kirill,
In order to use your CVS-1454 you will need to buy the LabVIEW Real-Time Module and Vision Development Module as these features are not supported in your version of LabVIEW.

How to add a new metadata field to iPhoto where new field is calculated as age in years and month based on a specific date and the date photo was taken ? I want to calculate and display the age of my two kids on every photo.

Hi
How can I add 2 new metadata-fields to every photo in iPhoto ?
The new fields should state the age of my kids in years and months based on the date that they were born and the date that photo is taken.
Exampel:
My son is born 01.01.2010
My daughter is born 01.01.2012
Photo taken by data
Aage of son
Aage of daughter
01.07.2011
1 year 6 month
not born yet
01.01.2014
4 year 0 month
2 year 0 month
I would like to be able to search by kids age and get the info displayed when doing slideshows.
How to do this in iPhoto ?
Any alternatives to accomplish the same ?
Kind regards

It can't be done with iPhoto. There are some DAM (digital asset management) applications that can write to other IPTC fields that iPhoto can't read. One such app is Media Pro 1.
However you would have to calculate the age for each date and add it to one of the fields. There are online age calculators that can do that for you: Age Calculators
If you go thru that much trouble then use iPhoto, make the calculations and add the age to the Description field. Then you can use Smart Albums to search for 1year 6 month text.

Error while trying to send a file through XI to SAP R/3 based OLTP system

Hi all,
I encountered with an error in the runtime workbench for the below mentioned scenario
ERROR message
<b>Unknown error: javax.ejb.CreateException: Neither messager server nor application server are defined for system IXI</b>
SCENARIO
The manufacturing system triggers an equipment failure. The failure message is sent through SAP Exchange Infrastructure (SAP XI) to the SAP R/3 based OLTP system,
changing the equipment status to a failure state. This is achieved by triggering the execution of Remote Function Call (RFC) present in the OLTP system from the SAP XI integration server.
Thanks and regards
Jishi

Hi Jishi,
Please check the Receiver RFC communication channel in your integration directory.
Check the logon parameters provided. From the error message, I guess there is no application server or message server provided, which is mandatory for XI to logon to the target backend R/3 system.

Can a 128 ssd storage still effectively work if I install windows 8.1 plus msoffice and a window-based proposal system? I plan to buy a macbook air entry level with 1.7 gh i5 processor.

Can a 128 ssd storage still effectively work if I install windows 8.1 plus msoffice and a window-based proposal system? I plan to buy a macbook air entry level with 1.7 gh i5 processor.

If you are going to use Mac OS X and its associated applications, and a BootCamp partition with Windows 8, and MS Office and all of the work created there, you will more than likely run out of space on a 128 GB SSD pretty quickly...especially if you put any music, photos or videos on it. Those things take a lot of space so you will have to be very, very careful about what you want to put on a 128 GB storage space. You would be better off going for 512 GB with what you plan on doing with it.

Process flow for the Mid-year Status Changes based upon the Qualifying Even

Hi Experts,
I'm looking some information for the process flow for the Mid-year Status Changes based upon the Qualifying Events. Basically, I need to know, what would be the impact of these changes on various info types (Via IT0014 - Deduction changes & so forth) and the things that needs to be considered during it's Configuration and the things that needs to be checked due to the occurrence of the change. I would greatly appreciate any kind of help/document.
Thanks a bunch in advance,
Thanks,
Exertive.

Hello guys,
Can anyone has any kind of input on this? Basically, I need to know the procees for Mid-year status changes based upon Qualified events. Any kind of help is greatly appreciated.
