Invalid Coordinate System??

[Ehlert]

Hey,

I have made a very simple script in the vision assistant tool - when I run it within the tool, everything is fine - but when I put it in my VI, I get an "Invalid Coordinate System" error.

What I am trying to do is to first have a pattern matching to locate my object, then I want to set a coordinate system based on that, and use that for a reference for the rest of the script - but no matter what I try, the "set coordinate system" outputs "NaN" - eventhough the pattern matching is working perfectly.

any ideas?

Try by creating a labVIEW vi from vision assistant.

Hi Henrik

I've run into this behavior as well. This is a bug in LabVIEW 2013 it should be corrected in LabVIEW 2014.

In the mean time we have created a patch that you can use to solve this.

If you replace the attached file with that one that is already there in this folder:

<LabVIEW>\vi.lib\vision

and restart LabVIEW you issue should be solved.

ohh, and btw - the patch also speeds up the script by at least a factor 50 - was actually a bit worried since is was extremly slow when running on the target - the proformance meter claims that it should be able to run in less than 50 ms, but before this patch it took seconds...

Thanks for the update Henrik - I'm glad it solved the issue.
