a new method for estimating the uncertainty of measurement in three-dimensional measurement

摘要

during the measurement of a curve (or surface) on a real mesurertridimensionnelle machine, the image obtained is a curve (or surface) is discretized in the form of a cloud of points. in order to verify the specifications given in definition ledessin is an identification process. this is a perfect geometrical element according to a link (ega) cloud felt.this invention is an algorithm to estimate the parameters of the curves (or surfaces) and their uncertainties, taking into account the uncertainties of pointspalpu00e9es address canbe used, the criterion of association is less carru00e9s.cette does not estimate parameters the assumption of small displacements, and may be applied in any traps.
