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.
