Claim One:
1. A calibration system for a three-dimensional measurement system, the calibration system comprising: a calibration standard assembly positioned in a large scale three-dimensional volumetric area, the calibration standard assembly comprising: a stable base portion; a plurality of structural members disposed on the stable base portion; a plurality of target position nests coupled to the plurality of structural members, each target position nest having a known three-dimensional location measured with a coordinate measuring device and a plurality of retroreflective targets, the plurality of target position nests being configured to seat the plurality of retroreflective targets during measurement with the coordinate measuring device; a plurality of calibration targets each having a same diameter as a diameter of each of the retroreflective targets, the plurality of target position nests being configured to seat the plurality of calibration targets during calibration; and, a three-dimensional measurement system for measuring locations of the plurality of calibration targets, wherein the plurality of calibration targets are three-dimensional standards having known three-dimensional locations that are used in calibration of the three-dimensional measurement system based on measurements of the known three-dimensional locations of the plurality of calibration targets by the three-dimensional measurement system.
