Dynamic Metrology and ASTM E57.02 Dynamic Measurement Standard

Abstract

Optical tracking systems are used in a wide range of fields. The market for optical tracking systems has dramatically increased over the past several years to $1.2B revenue in 2014. This paper describes the new ASTM E3064 Standard test method procedures for optical tracking systems and will outline the theoretical basis for the analysis of the data from these systems. The paper will also verify the performance of an example 12 camera optical tracking system using these standard procedures and related analysis. An artifact, developed at the National Institute of Standards and Technology, was verified by a coordinate measurement machine and then used in two experiments to verify the test method. This and other in-depth papers are intended to be base references for ASTM E3064. Keywords: optical tracking, coordinate measurement machine, ASTM E3064 standard, reproducible performance, test methods, artifact 1 Introduction Optical tracking systems measure the three-dimensional, static and dynamic position and orientation of multiple markers attached to objects within a measurement space. Optical tracking systems are used in a wide range of fields including: neuroscience, biomechanics, robotics, and automotive assembly.
