Abstract
Official abstract text for this publication.
The present invention provides an elongation measuring apparatus, an elongation measurement system and a non-transitory medium recording a computer program, which enable measurement of an elongation of a chain without presetting a distance between rollers before use. Based on an image of three or more pins, two adjacent inter-pin distances are each calculated. As a result of a comparison between the two calculated inter-pin distances, the longer distance is determined as a pitch of an inner link and the shorter distance is determined as a pitch of an outer link. The outer link is not elongated while only the inner link is elongated, and therefore, a ratio of a difference between both of the pitches to the pitch of the outer link is determined as an elongation of a chain.
First claim
Opening claim text (preview).
What is claimed is: 1. An elongation measuring apparatus for measuring an elongation of a chain based on a taken image of the chain in which a plurality of inner links and a plurality of outer links are alternately connected to each other by internally fitting pins of the outer links into cylindrical bushings of the inner links, the elongation measuring apparatus comprising: at least one memory that stores a computer-executable program; and at least one processor that, when th…
