Product gauge methods and apparatus for use in the optical determination of the acceptability of products

摘要

A product gauge is disclosed for use in the optical inspection of products. The product gauge can be produced from the image of a model of the product. The product gauge can also be electronically constructed on a video screen by a computer line-drawing program. The product gauge aids in the alignment and the processing of information by the optical inspecting means including aiding an operator in determining whether a product is acceptable. The product gauge can be used to quickly and accurately tailor a generalized product inspection apparatus to specific products and thus ease the change from inspecting one product to another product.
