Reverse engineering of geometric models - an introduction
Specific issues addressed include characterization of geometric models and related surface representations, segmentation and surface fitting for simple and free-form shapes, multiple view combination and creating consistent and accurate B-rep models. Expand
Constrained fitting in reverse engineering
This paper considers simultaneous fitting of multiple curves and surfaces to 3D measured data captured as part of a reverse engineering process, where constraints exist between the parameters of theExpand
Algorithms for reverse engineering boundary representation models
A procedure for reconstructing solid models of conventional engineering objects from a multiple-view, 3D point cloud is described, with emphasis on producing accurate and topologically consistent boundary representation models, ready to be used in computer aided design and manufacture. Expand
Advanced surface fitting techniques
Main results include algorithms to compute a good initial parametrisation, a fitting strategy to maintain tight tolerances and smoothness simultaneously, to handle weakly defined control points and a shape dependent knot refinement procedure. Expand
Reverse Engineering
This chapter summarizes a representative set of algorithms that explain the way reverse engineering can be carried out by describing the way point data may be captured from an object and the way points from multiple views may be merged to form a single point cloud. Expand
Reverse Engineering Regular Objects: Simple Segmentation and Surface Fitting Procedures
A non-iterative algorithm for direct segmentation is presented, where well-known techniques from computer vision are combined with new procedures for processing point and normal vector data, based on laser scanned point clouds with relatively high density and high accuracy. Expand
Applying geometric constraints for perfecting CAD models in reverse engineering
Algorithms to eliminate inaccuracies and create "perfected" B-rep models suitable for downstream CAD/CAM applications are presented and special measures for partial and approximate constraint satisfaction are proposed. Expand
Methods to recover constant radius rolling ball blends in reverse engineering
The purpose of the current investigation is to present and compare algorithms for recovering constant radius rolling ball blends, the most widely used class of constant-radius rolling ball blended surfaces, due to their simplicity and intuitive behaviour. Expand
A Multi‐sided Bézier Patch with a Simple Control Structure
A new n‐sided surface scheme is presented, that generalizes tensor product Bézier patches, that is defined over a convex polygonal domain and computed from generalized barycentric coordinates. Expand
Direct segmentation of smooth, multiple point regions
The direct segmentation method described in this paper is based on a special sequence of tests, by means of which a large point cloud can be robustly splitted into smaller subregions until no further subdivision is possible. Expand
