Photogrammetry – Benefits of subsea metrology

These advantages make photogrammetry a powerful tool for subsea metrology, offering a combination of accuracy, efficiency, and versatility that is well-suited to the demanding requirements of underwater surveying and inspection tasks.

Cost-effectivenessThe flexibility, scalability, and relatively low cost of the photographic methods make them increasingly attractive for subsea industry applications
Suitability for kinematic and thermal load testingPhotogrammetry systems can generate precise measurement results even at extreme temperatures, making them ideal for component tests in industries like automotive
Reduced equipment requirementsCompared to some other methods like LiDAR, photogrammetry can enable faster data acquisition with less equipment
Detailed visual documentationPhotogrammetry produces full colour 3D models that allow for assessment of structural changes, marine growth, and areas of degradation
Real-time feedbackThe dynamic acquisition method provides immediate feedback on visibility and coverage, ensuring the quality of data being acquired
Rapid data acquisitionPhotogrammetric surveys can be completed quickly, enabling efficient data collection
Versatility in lighting conditionsPhotogrammetry can cope with various lighting conditions, from bright sunlight to darkness, making it suitable for use outside enclosed spaces
Flexibility and accessibilityPhotogrammetric systems allow users to move freely around large objects and reach every corner, which is particularly advantageous for very large measuring objects
Comprehensive data collectionIn a single survey, photogrammetry can gather a very high quantity of information about the subsea environment, structures, and points of interest
High accuracy potentialPhotogrammetry can provide highly accurate 3D models and measurements of underwater structures and environments
