Ground laser scanning of the flyover through the railway for the purposes of its reconstruction

Abstract

The article presents the possibility of obtaining geometric parameters of an flyover passing through a railway using ground–based laser scanning technology using modern equipment Leica Scan Station C10. The practical significance of using the chosen method lies in the fastest and most convenient scanning of the object, reducing production costs and, of course, high accuracy of the spatial data obtained necessary for the reconstruction of the flyover. A study of the use of ground-based laser scanning technology to obtain spatial data of the flyover was conducted, as a result of which the advantages of the chosen method were revealed. Also, based on the data obtained, a comprehensive three-dimensional model and two-dimensional drawings were prepared, such as the facade of the flyover, its plan and drawings of transverse profiles. Thanks to the compiled drawings and models of the bridge structure passing through the railway, the design work on the reconstruction of the facility has become much easier and more efficient. The presented experience confirms the need to introduce modern technologies, namely ground-based laser scanning in survey activities in order to develop and detail design solutions for the reconstruction of flyovers.
