Labview and vision inspection

[wieger]

Rick,

look at http://www.cft.philips.com/industrialvision/

They have framegrabber products and a LabVIEW vision toolbox called PROMISE

good luck with it

Hi Jack

I am new to NI vision builder. I started off well, but i face a problem. Would you mind to assist me?

I had created all the algorithms and inspection methods needed to locate my obj. I did a loop test on the NI vision builder, it run well and locate my obj. After exporting it to labview, it generate the a series of VIs and Lib files(7 or 8 files). I am able to link the main prgm to my labview. But i need to get the co-ordinates as well. How do i select which VI or lib to input the coordinate to my existing program ?

thank you

Hello khsay,

Thank you for contacting National Instruments.  You mentioned that you need to obtain coordinates for your program.  Depending on the coordinates that you need and the Vision Builder steps that you have, there should be coordinates available at the particular VI of interest.  What coordinates do you need for your program?  Does your Vision Builder code contain a function that will generate these coordinates?

Hi Mike T,

Thanks for offering to help. let me explain again. I am using the NI Vision Builder AI 2.6 to track an object using a balser camera. In my script i need to do serveral key steps, such as colout pattern matching. On the setting's tab, I am allowed to view the co-ordinates of the object(centre). I want to import the value of xy- co-ordinate from the NI vision builder AI to my existing labview which will control the mouse cursor according to the value of the co-ordinates.( I had done that!).

In order to do that, I export the script from NI vision builder to VIs. There are many VIs and LLBs created. Hence, I am a little lost. I have check one of the llb files which might be close to what i am trying to find.

common.llb>> IVB Get CoordSys.VI

this VI allows me to get the values. But i am not sure if it could works. Is there any other methods which might help me achieve my objective? Please Assist.

Hello khsay,

Assuming that the coordinates are what you want to set your mouse cursor to, you can do this using a function call to SetCursorPos, which is part of the Windows SDK.  Please refer to the following link:
