Purpose This paper aims to propose a novel model and calibration method to improve the absolute positioning accuracy of a robotic drilling system with secondary encoders and additional axis. Design/methodology/approach The enhanced rigid-flexible coupling model is developed by considering both...

Purpose – The purpose of this paper is to present a unified approach to uncertainty and sensitivity analysis for camera calibration. Design/methodology/approach – The approach is based on the fact that camera calibration is a problem of parameter estimation and the parameters of interest are...
