Often in vision if a picture is analysed then the original is overwritten / destroyed.  Is it just a case of taking the image reference before the processing and then overlaying the analysis result onto the original Image.  Difficult to explain and I do not have the vision toolit to hand.

You often have to copy the original image and use one copy for image processing, then overlay the results onto the original Image, not the processed one.

This is what solved the issue, I just missed the significance of what you & ShaunR said until after taking an NI Machine Vision course last month.  I still need to overlay the processing parts, but the big nut has been cracked.  Thank you.

So you don't need LabVIEW for this particular problem; that's good.  You can probably do this with LabVIEW, but it's not the best tool for the job; LabVIEW is really good for applications that interface with hardware.  Can you pick a different project to familiarize yourself with it?  Something with DAQ or instrument control?

Why must you use LabVIEW?  This sounds like a job for Excel's VBA.

The lighting & focus are the same.  I expect that the camera settings are different, but I don't know what to look for.  I can LabVIEW well enough, but I've never visioned.

I asked a question on the NI site about an odd difference in images in software that I inherited - http://forums.ni.com/t5/Machine-Vision/What-s-wrong-with-this-image/m-p/3573561#U3573561

I get different images in two versions of a software my predecessor wrote, but I can't get the source code to make my desired image (the first one).  I've attached the Vision Acquisition Express VI that is used in the software on my NI post.  Can you tell me the difference and how I can get the nicer image?

Please provide me better option.

Buy the module and ask NI.

Preparing for standard interview questions like "what is your greatest weakness" is a must

I'd have to say that my biggest weakness is that I care too much.  I will work and work and work and work until the job is done ahead of schedule and below budget with all expectations exceeded and everyone is happy.

Puke!

If you have significant experience in any programming languages, but not LabVIEW specifically, I'd be satisfied (as an interviewer).  Graphical programming is certainly a different kind of animal, but programming is programming, and you can add another language to your repertoire faster than you learned the first few.  If you don't have significant experience programming, share with them (and with us, please) what you hope to bring to the table while you improve as a developer.

I've interviewed several engineers that had the AUDACITY to put LabVIEW on their resume just because it was in a class they once took or they used someone else's stuff.  Oh, the horror!  I was not impressed and they were not hired.  I'm thoroughly jaded...

So Boss. You question the suppliers QA? I'll need you to sign this request in order Our that Goods In switch to 100% inspection sampling and I'll hand it personally to the Goods In manager along with your extension number  When will you be at your desk? 

Our Materials department tells me that "Suppliers are liars".  Still, we don't do 100% inspection on incoming goods.

I literally shaved the day before.  I can grow a mean beard, but

I had to zoom into the picture (to see your name badge) to be sure it was really you.

Now I feel like growing some hair on my face.  Good job, gentlemen.

I figured that you knew, I just wanted others to see what's already been said.  This is a common practice on these fora, not a commentary about you.

Cross-posted.

hooovahh's post represented my immediate reaction to your offer; I look forward to the source.  Of course, why should you trust us?  Once we see how you did it, we can write whatever we want as a high score to the "altervista space".

You'll add the random number and a different constant for each row you make.  The random number generated will be between 0 and 1, so, for the first row you'll need to add zero; add one for the second row, etc.  Try making nested loops and see what you get.  Do you understand how rows & columns of a 2D array are generated in this fashion?  Are you familiar with the For loop's "i" and "N" terminals?

Show me your code, Wireworker, and I'll show you mine.

Where do your numbers originate?  You can use nested For loops, an Addition node and a random number generator.

You can "Print" VI documentation to html.

I work with tight controls on what we can do with computers on our company's network.  The idea has been tossed around that we could build our own computers that never see the network so we can retain admin control over them.  Then, using a networked & not-under-our-control PC with two network cards, we can present the Front Panel of our application from the "free" PC to the "non-free" PC.

Here's a Quick Drop plugin that loads all cases into a Tree, and the elements are draggable to reorder the cases - https://decibel.ni.com/content/docs/DOC-24058

It used to be a RCF plugin in the LAVA CR - https://lavag.org/files/file/90-caseselect/

 

These videos have also been included in the NIWeek 2015 folder

I love you.

Teaser!

Write your own function.

Seriously, though, you need to share more information about what you're trying to do.

The more you explain, the more confused I get.

I'm not clear on your intent.  I think you'd be better off setting all of the pins and a delay in each row.  If you don't want a delay, just set it to zero.

ExcelTest2.txt

Why are you initializing an array in your For loop?  You want to replace elements; here's a very quick way to accomplish that:

Also, you don't need to use (ever) the Stop command; just put all of your logic in the other case.
