3D data capturing, 3D modelling and 3D printing

We use laser scanners, total stations and cameras to capture 3D point clouds of civil structures like buildings or natural objects like rock faces or caves. Subsequently, the point clouds captured from different positions are registered to yield one common point cloud in a given reference frame. This point cloud is modeled and a numerical model of the structure is obtained. Finally, this numerical model is printed using 3D printers and thus a physical model of the real object is obtained.
