Lasergrammétrie mobile : étude et utilisation d'un système mobile de cartographie 3D en milieu ferroviaire : le GRP 5000

Abstract : The techniques for recording and surveying of railway environment are traditionally made by track recording vehicles or by tacheometry. Since a couple of years, track measuring trolleys are used. The GRP 5000, employed for clearance analysis is developed by the company Amberg technologies registers internal geometry rail track and it’s capable of capturing three-dimensional data from surrounding objects through a laser scanner 3D. These systems, called Mobile Mapping Systems involve lasers scanners which are able to acquire a lot of profiles. Huge amounts of data are acquired in a limited time compared to fixed terrestrial time. These data can be georeferenced in order to obtain a point cloud and a 3D digital mock-up. These technological advances and the control of precision positioning devices provide new perspectives for fast and large-scale surveys.
