Convert pixel coordinate to Realworld coordinate

[Zealous]

Hi!

When I give XY imagecoordinates to "IMAQ corvert pixel to realworld" it seems that it does not give right coordinates back. For example when I send coordinates X(100) Y(50) function returns X(-0,15)Y(0,26) back. So what those coordinates can be? I think answer should be like X(102)Y(52) or so, but this doesnt seem to be right..

Hi!

Just updating my post.

Just needing advices to represent aberration errors. My goal is to draw line from (flawed) pixel coordinate to where that pixel should be in the picture. It is shame that NI calibration functions only gives so few outputs. Like to hear your advices to solve this probem 🙂

Zealous,
How is your "Learn calibration template" vi configured?
-Do you use units?
-Is your origin pixel ok?
-Have you tried to check the corrected image and error map?

Hope this helps.

Hi I found out that function gives dX and dY so just need to do littlebit calculation and my problem solved... or I think it so 🙂
