Job: To provide a detailed dense point cloud and photorealistic 3D model to be used for change detection.
Challenges: Newcastle Port Corporation needed a way of accurately, reliably and affordably monitoring the change in the Newcastle and Stockton break walls. Airsight Australia and Monteath & Powys collaborated to combine cutting edge UAV mapping technology innovative 3d model software to accurately highlight exactly where changes are occurring in the break wall armour.
Solution: Airsight Australia using their multi-rotor UAV to generate incredibly dense point cloud and 3D model (5mm per point) of both Newcastle and Stockton break walls. Using Monteath & Powys innovative and extensive 3D surveying capabilities they combined the above ground 3D model with the bathymetric data acquired by the Port of Newcastle survey vessel to create detailed and accurate below and above water model of both break walls.
Results: Airsight Australia was able to complete the survey of both break walls in less than 8 hours (4 hours per wall) and completed the post production and reduction of photogrammetry data in under 22 hours.
