Abstract

Abstract

Laser tracker is widely used in the performance measurement of industrial robots because of its high precision, large measurement range and multi-dimensional measurement. For conventional industrial robot position measurement, a single-base station laser tracker can meet the demand. However, when measuring complex objects such as dual-arm robots and multi-robot linkage systems, the single-base station laser tracker can not meet the requirements of synchronous real-time measurement, and a multi-base station laser tracker is required for coordinated transfer measurement. Based on the measurement principle of multi-base station laser tracker, this paper carries out the research on the error influencing factors of coordinated measurement of multi-base station laser tracker, analyzes the influence of different influencing factors on the measurement error, and compares the solution accuracy of coordinate transformation by the least square method, SVD decomposition method and quaternion solution method through simulation experiments, which has certain guiding significance for the promotion and application of the measurement system of the multi-base station laser tracker system in the future.
