Abstract
A new approach to the reconstruction of a surface from an unorganized set of points in space is presented. The point set may for example be obtained with a laser scanner or a manual digitizing tool, and is the only source of information about the shape of the acquired object. The basic idea is to calculate the euclidean minimum spanning tree (EMST) of the given points. The EMST is then augmented to the so-called surface description graph (SDG). Finally the contours defined by the SDG are filled with triangles. The advantage of that approach is that also highly non-convex and even disconnected surfaces are reconstructed quite reliable. This is demonstrated for a variety of data sets. Zusammenfassung Es wird ein neuer Ansatz zur Rekonstruktion einer Flache aus einer ungeordneten Menge von Punkten im Raum vorgestellt. Die Punktmenge kann zum Beispiel mittels Laser Scanners oder eines manuellen Digitalisierwerkzeugs erzeugt werden und ist die einzige Informationsquelle bezuglich der Form ...
