Metrological stability of multi-camera photogrammetry systems

CIRP Annals, vol. 75, pp. 637–641

Abstract

High-speed infrared photogrammetry systems have traditionally been used in entertainment industries for motion capture. Recent work has investigated the use of these systems for large-scale dimensional metrology applications. This paper describes a methodology to quantify the stability of these systems through information obtained in the “system calibration” process. The developed metric is applied to two laboratory motion capture systems of vastly different scales, and the subsequent experiments qualitatively relate the measurement capability of the systems to this stability metric.
