In the manufacturing industry, the term ‘vision inspection’ is used to refer to cameras placed along a production line that verify quality aspects and detect errors/irregularities.

They’re increasingly used as an alternative to manual quality control checks carried out by real humans. You can think of vision inspection systems kind of like ‘artificial eyes’. They take photos of products as they pass along a production line and compare them to a template to make sure everything is correct. If something is wrong, the line is stopped.

The kind of thing they’re checking for is usually related to packaging/printing errors. Packaging can also be verified through in-line barcode scanning but barcodes can’t always be placed on the packaging of all products. For example, this might be because the package has artwork which can’t be printed over. In these cases, vision inspection systems provide an alternative way to verify packaging.
