IMAQ find straigth edge

[vgravel]

---

 Hello,

I try to mesure an edge using the IMAQ Find Straight Edge VI. As seen on the attached image, some of the the edge was left out by the algorithm.

I tried changing some parameters but without luck. Does someone know what parameter should be changed to get the full edge. The algorithm found the bottom edge perfectly.

For my eyes, the upper edge is pretty straight and sharp so I do not understant why the left part was left...

Thanks for your help!!

Hello Vincent,

It looks like the edge of you image is fairly blury. Maybe changing the kernel size or gap would help. The easiest thing to do would be to open up vision assistant and play around with your algorithm visually.
