Abstract
This paper presents a semi-automatic approach for creating a 3D model from point clouds. The proposed approach consists in the development of two successive algorithms. First, the segmentation of the point cloud in geometric primitives is made based on RANSAC paradigm. Then, in a modelling step, the geometric primitives are used for either surface modelling or boundaries extraction and more particularly sectional view extraction. The whole approach is illustrated with examples of historical buildings. Regarding the results analysis, the developed approach is promising. Finally, potential improvements are suggested and should facilitate the creation of HBIM.
