A COMPUTER-IMPLEMENTED METHOD OF IDENTIFYING A PERFORATED FACE IN A GEOMETRICAL THREE-DIMENSIONAL MODEL

摘要

A computer-implemented method of identifying a perforated face in a geometrical three-dimensional, 3D, model, the method comprising: obtaining two-dimensional, 2D, representations of faces of the model; creating a face image representing a rendering of each of the faces in 2D representation; comparing the face image to labelled perforation images in a neural network; and using the comparison to detect any perforations and classify the face image as belonging to one of: a perforated and a non-perforated face.
