In this study a series of procedures were implemented to compare acquired surfaces with the nominal data or to directly compare different scanned surfaces. In particular a morphological evaluation algorithm based on the Extended Gaussian Curvature (EGC) and a method to compare features based on aggregate nor- mal orientation are presented. To perform the comparing feature method a simple procedure for segmentation was developed. The main characteristic of the two methods is robust behaviour referring to the scan orientation. The procedures were implemented as software modules in a graphic environment.

Abstract
In this study a series of procedures were implemented to compare acquired surfaces with the nominal data or to directly compare different scanned surfaces. In particular a morphological evaluation algorithm based on the Extended Gaussian Curvature (EGC) and a method to compare features based on aggregate nor- mal orientation are presented. To perform the comparing feature method a simple procedure for segmentation was developed. The main characteristic of the two methods is robust behaviour referring to the scan orientation. The procedures were implemented as software modules in a graphic environment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
