Capturing one of the worlds longest tunnels
Chapter 2: On the fast track
On the fast track
Facing a very short and divided up timeframe of only a few weeks, Roulier and his team knew they needed a fast and efficient method to capture all the available data. They found this in the Leica Pegasus:Two’s seven cameras providing full 360-degree dome imagery combined with the scans of the onboard LiDAR profiler.
Easily attaching the capture platform to the prototype of the firm’s specially-designed rail trolley, the engineers were able to quickly and effectively maneuver over the outdoor tracks to collect a few billion points. By constantly capturing data on the move without disrupting ongoing construction, safety increased for Grunder and other employees. No longer were the surveying engineers required to trapeze through a risk-filled construction site, and construction workers no longer needed to worry about avoiding surveyors or instruments set up in the midst of their site.
“This non-contact and kinematic measurement ability allows us to record everything without interruption, significantly decreasing risks," said Roulier. “This mobile method also reduces the effort, saving the entire project on costs and time, with benefit for all working stakeholders.”
With the complete 3D surround capture of the Leica Pegasus:Two’s images and point clouds, no critical information is forgotten, either. With only one pass, all important documentation is made. The need to return to site on multiple occasions for data collection is eliminated, saving vital resources.
