Aerospace assembly GAP measurement using low cost smart tools with machine vision

Abstract

This paper details the conversion of mature machine vision technology from a fixed position automation line based device to a handheld technology and addresses the problems associated with maintaining a consistent camera distance and light source by using 3D printed hand tools. Specifically, the problem of gap measurement within aircraft wing assembly is used as an example application, however, the wider opportunities and functionalities associated with industry 4.0 are demonstrated and briefly discussed.
