Abstract The authors are developing an automated reverse engineering system for
reconstructing the shape of simple mechanical parts. B-rep models are created by fitting
surfaces to point clouds obtained by scanning an object using a 3D laser scanner. The ...

Boundary representation models reconstructed from 3D range data suffer from various
inaccuracies caused by noise in the data and the model building software. Such models can
be improved in a beautification step, which finds geometric regularities approximately ...

Abstract We present a simple and fast mesh denoising method, which can remove noise
effectively while preserving mesh features such as sharp edges and corners. The method
consists of two stages. First, noisy face normals are filtered iteratively by weighted ...

Abstract. The authors are investigating reverse engineering for reconstructing the shape of
simple mechanical parts. Currently, preliminary B-rep models can be created by fitting
surfaces to point clouds obtained by scanning an actual part using a 3D laser scanner. ...

Abstract Boundary representation models reconstructed from 3D range data suffer from
various inaccuracies caused by noise in the data and the model building software. The
quality of such models can be improved in a beautification step, which finds regular ...

Detecting approximate symmetries of parts of a model is important when attempting to
determine the geometrical design intent of approximate boundary-representation (B-rep)
solid models produced eg by reverse engineering systems. For example, such detected ...

Abstract Boundary representation models reverse engineered from three-dimensional range
data suffer from various inaccuracies caused by noise in the data and the model building
software. Beautification aims to improve such models so that they exhibit exact geometric ...

Abstract Sculptural reliefs are widely used in various industries for purposes such as
applying brands to packaging and decorating porcelain. In order to easily apply reliefs to
CAD models, it is often desirable to reverse-engineer previously designed and ...

Abstract An algorithm is presented to automatically generate bas-reliefs based on adaptive
histogram equalization (AHE), starting from an input height field. A mesh model may
alternatively be provided, in which case a height field is first created via orthogonal or ...

Abstract Reverse engineering allows the geometric reconstruction of simple mechanical
parts. However, the resulting models suffer from inaccuracies caused by errors in
measurement and reconstruction so such models do not have the exact congruence, ...
