Apparatus and method of automatically extracting sweep/extrude/revolve feature shape from atypical digital data

Abstract

Provided is an apparatus and method of automatically extracting a sweep/extrude/revolve feature shape from atypical digital data, including a scanner which scans a 3D object so as to provide 3D scan data indicating a shape of the 3D object, and a computing device which extracts a feature shape from a collection of the 3D scan data collected from the scanner, wherein the computing device includes an extracting means for extracting multiple points from the collection of the 3D scan data and producing initial section from the extracted multiple points; an aligning means for aligning the sections so that shapes of the sections are coincided with each other; a compensating means for forming an initial path, generating an initial profile and then compensating the path; and a modeling means for performing a modeling function using the compensated path and profile.

Dependencies are inferred from the claim text.
