InspectionLaser ScanningmappingPhotogrammetryRailway Bridge: Hybrid Terrestrial LiDAR & Aerial Imaging

Complex structures in active environments that require 3D models can be a tricky subject using a single survey technique. That’s why aerial imaging using drones and terrestrial laser scanning provide an ideal solution. The combination of high accuracy (±2mm) laser scanning points and high-resolution images can provide photo-realistic 3D models using “hybrid aerotriangulations.”

The client also required the 3D data to be referenced to OS National Grid coordinates, so RTK GPS was used for final position fixing.

The whole dataset was acquired in one day and despite being an active trackside environment, no unnecessary access in hazardous areas was required. Due to restrictions working near railway infrastructure, we employed pilots with the necessary qualifications for the task.
