REFERENCE MODEL AND ALGORITHMS FOR MULTI-STATION COORDINATE METROLOGY

Alistair B. Forbes

Abstract

This paper described models and algorithms for analysing data captured by coordinate metrology systems such as laser tracers, laser radar, laser trackers, theodolites and indoor GPS. Algorithms use structure-exploiting techniques to determine estimates of target locations and associated variance matrix efficiently. The calculation of the complete variance matrix enables valid estimates of uncertainties for quantities derived from the solution targets to be evaluated and provides a basis for improving the design of measurement strategies to reduce uncertainties.
