The purpose of reverse engineering design using 3D measurement data is an accurate reconstruction of existing part, in oder to accomplish this object first of all the extracting edges should be leading.
This study used edge-based method put out edge point from the measuring point data. And characteristics are analysed using the mean curvature block method of a fitting NURBS curve and defined edges through block removal condition. The results showed that only using the NURBS curve of maximum curvature analysis to define correct edge of real geometry is limited, but this segmentation approach provides simplified necessary condition for edge classification, and an effectiveness to classify a straight line and fillet etc.
