Vision assistant: seeing caliper & edge line-results in exported VIs

[xombox@seznam.cz]

Hello,

I wonder if is it somehow possible to see all caliper, edge etc. line-results in exported VIs (from Vision Assitant 8.6). I mean to see all those lines and shapes produced by detecton tools (see the screenshot).

E.g. I need to see all those green, yellow and red lines after running exported VIs.

Thank you for your answer.

Martin,

There is no way to automatically show those lines in LabVIEW.  You will have to manually draw them on the image based on the outputs of the IMAQ functions.  This can be done using the IMAQ Overlay functions.

This isn't exactly what you are looking for, but a few VIs in VDM 8.6 have options to overlay the information the VI returns. These VIs are IMAQ Find Edge, IMAQ Find CoordSys (Rect) 2 and IMAQ Find CoordSys (2 Rects) 2.

Hello Mr. Tyler Weston,

thank you for your tip. Indeed, it works fine but problem is that Vision assistant 8.6 doesnt use those VIs for pattern matching (it uses some IVA and pattern matching algorithm.vi) so I can not apply the overlay after exporting the vison assistant script to VIs. And the mentioned IVA, pattern matching algorithm don`t have the overlay option 😞

I have tried to rewrite my Vision assistant script manualy by using the VIs with overlay function you mentioned, but I don`t know how to measure distances between points detected by pattern matching. There is no example of using IMAQ caliper tool.
