Abstract
A determination system includes an imaging unit that captures an image of a gasket already used for flange fastening and an analyzing unit that analyzes, based on the image captured, a contact mark formed on the gasket as a result of contact between the gasket and a pair of flanges when the flanges are fastened through the gasket. The analyzing unit includes a detection unit that detects, in the captured image, a contact mark region indicative of the contact mark and enclosed with a first line and a second line, a distance calculation unit that calculates a distance between the first line and the second line, and a state determination unit that determines, based on at least the distance, whether the flanges are properly fastened through the gasket.
