line profile roi variable

[BluE12]

Hello,

i have built a vi with vision assistant, where a single horizontal line profile is included. If the acquired picture had the coordinate system X,Y, I want to expand the vi so that it puts out all possible horizontal lineprofiles (X1/Y0 to X1/Yn) to line (Xn/Y0 to Xn/Yn) in this order. So i have to vary the ROI (line), but how is this possible? I have no experience in labview, so its difficult for me with the different data types and functions.

thanks for help

I want to put it in a for-loop, using the counter to vary the line profile ROI. So, how can i connect the loop-counter with the ROI input of the "lineprofile", so that this is possible?

You'd have a better chance of getting help if you posted your VI to show what you have so far.

Hi Blue12,

you do not necessarily need to create a ROI for each line. You can get the line information directly with "IMAQ Line Profile". You can directly input the coordinates of your line and get the profile out.

Please save yourself from frustration and get some LabVIEW training before you try to implement applications.
