Influence of each of the geometric errors on the total displacement error of the machine [PDF]
IEEE EUROCON 2017 -17th International Conference on Smart Technologies, 2017 An algorithm for volumetric calibration is developed and verified practically by measuring of all geometric errors after numerical compensation. In this paper, analysis of the contribution of each of 9 translational and 9 rotational position dependent errors and each of 3 position independent errors in total displacement error vector is presented ...

Geometric Interpretations of the Normalized Epipolar Error
CoRR, 2020 In this work, we provide geometric interpretations of the normalized epipolar error. Most notably, we show that it is directly related to the following quantities: (1) the shortest distance between the two backprojected rays, (2) the dihedral angle between the two bounding epipolar planes, and (3) the $L_1$-optimal angular reprojection error.

An Error Analysis of the Geometric Baade‐Wesselink Method [PDF]
The Astrophysical Journal, 2004 We derive an analytic solution for the minimization problem in the geometric Baade-Wesselink method. This solution allows deriving the distance and mean radius of a pulsating star by fitting its velocity curve and angular diameter measured interferometrically.

IEEE Access, 2021 Till now, most calibration methods only compensate geometric error caused by inaccurate kinematic parameters, while the desired accuracy may still not be achieved when the robot is performing long-stroke, heavy-duty loading and unloading tasks.
