Approximation Of Scours Using Terrestrial 3D Laser Scanning

Abstract

In designing artwork as bridges, hydraulic calculations have a very important role due to the fact that they are behind their sizing. Bridge designer must therefore possess knowledge of hydrology, hydraulics of bridges and river banks regularization. A problem that arises during the design stage of bridges is the scour phenomenon surrounding bridge pier. Over time, there have been conducted a number of studies which led to the provision of a plurality of mathematical models that are intended scour prediction. In the present article we will present an experimental study to determine the bed profile and measurement of scours products around a pier bridge using 3D terrestrial laser scanner.

Three-dimensional characterization and calculation of highway space visual perception

“…G211 Highway is a two-way four-lane highway with a subgrade width of 16 m. The roadside vegetation of the demonstration section is sparse, and there are some farmlands, buildings, and power facilities outside the highway. Considering that the highway has a large spatial scale and the driver's line of sight moves fast while driving and has a weak sense of detail, in terms of the 3D data acquisition method, compared with manual 3D data and point cloud 3D data based on laser scanning ( Jocea et al., 2015 ; Bulgakov et al., 2015 ), the real scene 3D data obtained based on tilt photography are selected to complete the real scene 3D modeling of highway space.…”
