Geometrical Patterns for Measurement Pose Selection in Calibration of Serial Manipulators
Résumé
The paper is devoted to the accuracy improvement in geometric calibration of serial manipulators. Particular attention is paid to the optimal selection of measurement poses, which reduce measurement noise impact on the parameters identification precision. In contrast to previous works, the proposed approach yields simple geometrical patterns that allow user to take into account the joint and workspace constraints and to find measurement configurations without tedious computations. The advantages and practical significance of the proposed approach are illustrated by an example that deals with 6-dof serial manipulator.
