Du nuage de points à la maquette numérique de bâtiment : reconstruction 3D semi-automatique de bâtiments existants

Abstract : The creation of an as-built BIM requires the acquisition of the as-is conditions of existing buildings. Terrestrial laser scanning (TLS) is widely used to achieve this goal. Indeed, laser scanners permit to collect information about object geometry in form of point clouds. They provide a large amount of accurate data in a very fast way and with a high level of details. Unfortunately, the scan-to-BIM process remains currently largely a manual process because of the huge amount of data and because of processes, which are difficult to automate. It is time consuming and error-prone. A key challenge today is thus to automate the process leading to 3D reconstruction of existing buildings from point clouds. The aim of this thesis is to develop a processing chain to extract the maximum amount of information from a building point cloud in order to integrate the result in a BIM software.
