An embedded metrology system for aerospace applications
Abstract
As the move from craft-based aerospace manufacture to technology-based manufacture gathers pace measurement system assisted manufacturing will become common. Often these processes will require reliable, high accuracy position information of at least two objects at the same time. Photogrammetric is an ideal technique for such applications given that many points on an object can be measured at a single instant and this process can be repeated many times per second. As a result humans, actuators or robots can accurately place components or drill holes. This paper describes a photogrammetry system using a number of Digital Signal Processor based intelligent cameras and photogrammetric algorithms to provide real-time measurements integrated within a jigless assembly process.
