Abstract:

The present system provides a means to record an image of an item which is extremely difficult to inspect because of its peculiar shape or because the person who is inspecting it cannot come in close proximity thereto, such as red hot glass being measured for form and size immediately upon being formed into a bottle. The present system employs a television camera and logic circuitry to electronically compare the profile of said image against a standard item whereby the item being inspected or measured can either be rejected or accepted.
