100 CHAPTER 13. PRODUCT LABEL INSPECTOR
• Collect additional images of the defect-free label with varying amounts
of translation and rotation. Use these images during vision script devel-
opment to verify that your script detects zero defects even when the label
orientation changes.
•
Collect multiple views of each product label defect, again to verify that
your script delivers similar results for a given label defect with different
orientations.
• If you plan to use the “image flip” option in the Machine Vision App
template you will want to collect all of your images so that they appear
in the same orientation when you develop your script. Consider one of
these two options:
– Run either the Machine Vision App project or one of your exist-
ing projects with the “image flip” option enabled, adjust the camera
mode (resolution), right-click on the image display, and choose “Save
Image,”
– Run NI-MAX and save the images directly; these will need to be
flipped by batch processing in Vision Assistant; see
Batch Process a
Folder of Images

for details. Manually renaming all of the processed
images is a disadvantage of this technique, however.
