3D photogrammetry greatly improves the quality of outputs for data collected during underwater surveys. Accurate measurements taken throughout the acquisition process allow models to be constrained to real world dimensions. This enables a multitude of metrics such as distance measurements between structure points, surface area and volume calculations, overlaying CAD drawings and the integration of additional survey data.
3D spatial data allows the user to compare as-built, past or present models to determine areas of change. Rovco’s SubSLAM® live 3D vision system provides a greater understanding of asset condition than a visual survey alone, with no extra time required for data collection or post-processing. Subsea asset information is immediately available in CAD format, reducing the workflow between data collection, processing and reporting. Post-processing 3D data can results in super high resolution digital twins of the subsea infrastructures and environments, providing an unparalleled means of presenting data to interested parties.
