| Research Abstract |
Advancement of industrial X-rays CT scanner has made it possible to scan various mechanical parts. However, in order to utilize scanned data in design and manufacturing processes, image processing methods must be developed to process it. In particular thin plate structures such as automotive body requires CT scanning as they are made by welding sheet metal parts so as to have complex internal structures. The major problem here is that digital engineering systems are based on B-Rep representation of CAD models and thus cannot apply X-CT scanning data directly. This research project developed a contouring method to generate medial surface mesh from X-CT volumetric data.
