Abstract

Due to the excellent dynamic measurement capability of laser tracker, a combination of multiple laser trackers has the possibility of synchronously and dynamically measuring multiple targets. However, there is still an issue that measurement data from multiple laser trackers must be unified not only on the spatial coordinate system but also on the time reference. This paper studies a dynamic combined measurement method of multiple laser trackers. Firstly, the methods of the coordinate frames alignment, the time references unification and the uncertainty evaluation are studied. Secondly, the hardware and software designs of the dynamic combined measurement system are introduced in detail. Finally, the dynamic combined measurement of multiple laser trackers was applied to the test of the master-slave control delay time of the master-slave control RA equipment, and the experimental results demonstrate its feasibility.
