Need more documentation for "IMAQ Match Pattern 2 VI" and "IMAQ Learn Pattern 2 VI "

[Zoltan Szamosi]

Hy all.

I'm a student in final year and I use NI Vision to develop a PCB checking system as my final thesis.

My problem is that I can't find enough documentation for this VIs. I know how to use them but I have to write a detailed documentation about my project, and this is the reason why I need more information.

All information what I found is in the following documents:

- NI Vision Concepts Manual

- NI IMAQ Vision for LabVIEW User Manual

- Advanced Pattern Matching Concepts

- Pattern Matching Strategies -> http://zone.ni.com/devzone/cda/tut/p/id/3763

 All of those documents presents only a short description and how to use them. But what is need is a detailed presentation of the way that they works.

 If anybody know more details about these VIs please let me know

Best regards.

Zoli,

I think the information you request is part of NI's intellectual property, and as such is not public.

Anyway, one thing I would try is search NI's patents.

But If you are going to clearly mention labVIEW, will they insist on inbuilt functions explanation?

hy

Sorry for late response 😞

First of all I wanna thank you for your answer!

Valdimir you have right. I search on internet for NI patents and I found all the infromation what I need.

 Thank you again.

Best regards

hello , i have download the  patent by the link that you provide.

however , i think the discription of the pattern matching strategies is different with the patents .

i can't find any of the feature identification that the pattern matching strategies said in patents.

and the step of the pattern matching is different too.

In this illustrative example, we will create a program in Labview capture an image pattern, after the search to show the location and coordinates, you can check the following article in the following link
