Reconstruction of Lines in a Ship Hull with B-Splines
Francisco Pérez, Polytechnic University of Madrid
Abstract. A method for reconstructing lines from a point cloud with the use of B-splines is described in this paper. The method operates directly on the point cloud without any explicit or implicit surface reconstruction procedure, and works with unordered points. The presented technique is based on a Least Squared approximation, an iterative method for the parameterization and the use of fairing conditions. The method is designed to work with scattered data points from a 3D scanner and applied in ship reconstruction, where some specific lines contained in the ship hull are required and the full reconstruction of the ship hull surface is unnecessary.
Keywords: least squares, reverse engineering, point clouds.
