Abstract

A computer-implemented image processing technique for selectively recovering the features of an original CAD model after the original CAD model has been converted to a digitized image and a new CAD model generated from the digitized image. The original boundary representation provides a template to transform the representation through processing under governance of a programmed processor so as to recover accuracy and reintroduce feature edges and feature corners as well as other detailed features to the CAD model obtained from the digitized image, e.g., to enable detailed features to be retained that would otherwise have been lost due to the lossy conversion into image space. The method operates to better ensure that reconstructed boundary vertices lie on original CAD model surfaces and feature edges and corners are recovered.

Dependent claims

A computer-implemented method of processing a 3D mesh model representation of a three-dimensional object in a computer having a processor and a memory device, the method comprising:

receiving a 3D mesh model representation of the object in the memory device, the 3D mesh model including a plurality of vertices;
utilizing the computer to automatically detect one or more regions including a feature edge of the object;
receiving from a user identification of a selected region of the one or more regions;
and
modifying by the computer the 3D mesh model representation using code executed by the computer including selecting vertices having positions in the selected region of the 3D mesh model representation, and updating the positions of the vertices to more optimal positions.
