PDL - Investigation

Research

We cover 3 research lines:

A. PARTITION AND EXTRACTION OF NON-IDEAL, CYLINDRICAL SURFACES WITH SPIN-IMAGES

Principal Investigator: Lander Barrenetxea

The laboratory has developed a cylindrical surfaces segmentation algorithm using spin images to verify geometric tolerances. These spin images are used as multi-scale shape descriptors, without pre-filtering of the scanned surface, and without mesh reorientation to fit the CAD model. This method has been tested with scanned items in the laboratory and developed with Matlab.

B. NEW TECHNIQUES AND METHODOLOGIES IN THREE-DIMENSIONAL NON-CONTACT SCANNING SYSTEMS APPLIED TO ENGINEERING DESIGN

Principal Investigator: Olatz Etxaniz

This research line aims at developing an algorithm for the semi-automatic extraction of geometric features from a triangular mesh, in order to generate a CAD model so that the geometric, topological and dimensional constraints of the original design can be recovered.

C. INTEGRATION OF REVERSE ENGINEERING TECHNIQUES AND ANALYSIS OF MECHANISMS IN THE DESIGN OF DENTAL PROSTHESES IN A CAD ENVIRONMENT

Principal Investigator: Eneko Solaberrieta

Another research line of the laboratory is based on Dentistry and is focused on developing a virtual methodology for the design of dental prostheses. Nowadays, there is a collaboration Project with the Department of Prosthodontics of the Martin-Luther University of Halle-Wittenberg of Germany aiming at developing a virtual dental articulator and a digital face bow.
