Sensitivity Analysis for Simulated Annealing-Based Fitting of CAD Models to Point Clouds of Digitized Parts

Abstract This paper addresses the way a simulated annealing-based fitting strategy can be enhanced by leveraging sensitivity analysis able to characterize impact of variations in parameters CAD model on evolution deviation between itself and point cloud digitized part fitted. The principles underpinning adopted algorithm are briefly recalled. applied is described together with comparison resulting curves changes imposed annealing algorithm. suggests several possible improvements that discussed. overall approach illustrated single mechanical parts but it directly extended parts’ assemblies. It particularly interesting context Industry 4.0 update digital twins physical products systems.
