Application of 3D Laser Scanning to Computer Model of Historic Buildings

The paper contains an analysis of the application of 3D scanning in the process of creating a very precise numerical model of historical buildings. 3D scanning is used in inventory documentation with the visualization of a building and the creation of 3D models in most cases. As a result of 3D scanning a point cloud consisting of million points creating the spatial image of the scanned building is received. It is possible to convert this point cloud to the form of the geometrical mesh of triangles or the set of parametric surfaces using the appropriate software. Next, by using CAD programs can get the appropriate numerical model for FEA and static-strength analysis. The measurement technology based on 3D scanning is slowly replacing traditional measurement inventory methods meeting the needs of the monitoring and protection of historical buildings. The evolution of the 3D laser scanner is developed in order to increase the speed and accuracy of measurements and extend the research area from one measuring position.
