 Road tunnels and technology in an operational perspective

Laser scanning of tunnels Featured

Written by  Oct 17, 2017

The point cloud created by the laser scan is mainly used to evaluate the conditions of the pavement but can also be used to gather data from the side area and the tunnel walls. The report from such a scanning gives the necessary data for analysis and give the tunnel operator a chance to follow up the development of the road surface, the rock conditions and the construction, from one year to another. 

ViaPPS is such a Profile System designed to examine the condition of road surface and side area. Mainly developed for pavements, but the technology gives now extended opportunities. The whole system is mounted on a vehicle, such as a van, car, truck or trailer, and the mounting on a vehicle gives an effective work process. 

The most common use is to carry out wall and ceiling measurements to document the size of the tunnel. But it can also be used to register objects in the tunnels. The challenges will always be tied to the accuracy of registrations and if you get a full registration of all objects. There is carried out several tests on this system, and the Road authorities are still testing.  

The ViaPPS offers automatic inspection of roads, 3D mapping, Automatic reports and instantly available data. A high – resolution camera, a thorough point cloud and accurate positioning of data provide a sufficient framework for reliable results.
