Abstract
Laser tracking systems are the basic tool used in large-scale measurements in such fields like aviation or automotive industries. Except to the standard applications like the construction of features from individually measured points, they can be also used in the scanning mode measurement to obtain a trajectory of moving target. Such application can be met for example during the industrial robots accuracy verification. Evaluation of the accuracy of these systems, in particular when they operate in scanning mode, is difficult due to the multiplicity of parameters affecting the measurement uncertainty. Factors that have an impact on accuracy of the Laser Tracker system include user-defined parameters that determine the density of points acquisition during scanning. Authors try to assess the impact of these parameters using a methodology that utilizes coordinate machine with high repeatability. A Spherically Mounted Retroreflector system installed on the coordinate measuring machine quill allows the Laser Tracker system to track the movement of the machine along the programmed path. Coordinate measuring machine performing continuous movement enables scanning measurements of specific features and their evaluations. By repeating measurement procedure for changing scanning mode parameters it is possible to indicate differences in the accuracy of the system. Basing on the obtained differences authors propose the limits for tested parameters which allow to achieve the optimal ratio of point acquisition density and the measurement duration for scanning measurements performed on the laser tracking system.
