Laser Range Data, Photographs and Architectural Components
Year: 2008
Type: conference-paper
Abstract: In this paper we deal with 3D modelling from point clouds issued from laser scanning and also from photographs. Architectural parametric elements are semi-automatically adjusted in real time to the point cloud by varying the parameters describing the element. The scanned picture is correctly positioned in the virtual scene relatively to the point cloud and to other 3D parts of the scene. In the two cases (photograph and point cloud), points can be selected (3D points in the range image and 2D pixel in the photograph) and the building of the architectural element is processed relatively to the dimensions and positions specified by these points. Our research is carried out on various architectural styles (ancient, classic, gothic, khmer). The application field of our method is wide: it goes from cultural heritage virtual documentation to accurate model for archaeologists based on laser scanning of relics of the past. 3D models of existing buildings for lighting simulation, movie or game sceneries are also other possibilities.
