Gert,
Vision Builder for Automated Inspection has a limitation where it can only process 1 image at a time. It can acquire or open more than one image at a time in a script, however, each step only has access to the last image opened/acquired.
Vision Builder 2.6 has the ability to add a custom LabVIEW VI as a step. It would be possible to have a VI save one image to disk, then acquire another image and have an additional custom VI to open the last acquired image and the saved image and combine them as one image as pass it back out. This, however, will tremendously slow the speed of your script since you are saving to disk during steps.
After thinking about it a little more, it might be possible to speed things up a little by converting one image to a string in a custom LabVIEW VI step and pass that string to another VI to combine with the last acquired image. This should be a little faster since the hard drive is not being accessed.
Hopefully that gives you some ideas. Good luck with the project!
