Bias and uncertainty of the nonlinear least-squares sphere fitting algorithm to small segment angle surfaces

Bias and uncertainty of the nonlinear least-squares sphere fitting algorithm to small segment angle surfaces
Bias and uncertainty of the nonlinear least-squares sphere fitting algorithm to small segment angle surfaces
This paper is a introduction to the reliability and the robustness of nonlinear least-squares sphere fitting algorithm over small surface segment angle. The reliability of the algorithm has been tested by comparing it with special designed algorithm for spherical surfaces within small segment angle. The bias and the uncertainty of the fitting algorithm also have been investigated on the spherical surfaces with random surface irregularities.

Abstract

This paper is a introduction to the reliability and the robustness of nonlinear least-squares sphere fitting algorithm over small surface segment angle. The reliability of the algorithm has been tested by comparing it with special designed algorithm for spherical surfaces within small segment angle. The bias and the uncertainty of the fitting algorithm also have been investigated on the spherical surfaces with random surface irregularities.
