Vision systems belong to this category when they do one or more of the operations reported below:
- Morphological checking
- Checking for correct assembly
- Checking for surface defects
- Checking for presence/absence
Vision systems belong to this category when they do one or more of the operations reported below:
It is possible to check that the arrangement is correct before the assembly operation. It is also possible to verify that everything has been correctly mounted at the end of the production phase.
This control also uses various analysis techniques: line profile, blob analysis and edge detection.
To do this kind of analysis correctly an accurate illumination system is important, especially when we have to work with reflective surfaces. For wide surfaces the use of a line scan camera may be useful.
The presence or absence of specific details can be verified directly by the use of a pattern matching algorithm, or in other cases, it is possible through projecting special lighting patterns.
