Photogrammetry, pushing the limits subsea - bertrandchazaly. com TechnipFMC and FUGRO teams have solved the problem by implementing a short acquisition and processing chain using subsea photogrammetry The idea was to use the ROV HD video cameras already mobilized on site
A Comparison of Five Main Metrology Techniques in Use Today Photogrammetric metrology is a highly specialised application for subsea metrology applications The basis of photogrammetry is to build a three-dimensional model based on a sequence of two-dimensional photographs
Africas Largest Subsea Oil and Gas Network | Fugro Our innovative use of software saw accurate, on-time delivery of 76 acoustic metrologies and as-built survey reports for 270 structures, 39 flowlines and 41 umbilicals at depths of up to 2000 m within a 300 km² array
Subsea 3D imaging and metrology - Ashtead Technology Ashtead Technology is a leader in subsea 3D measurement and metrology solutions utilising advanced laser, video, photographic, and sonar technologies to deliver precise dimensional representations of subsea geometries, interface points and as-installed equipment
Underwater Photogrammetry and Subsea Metrology Horizon GmbH offers fast delivery of high-accuracy Subsea Photogrammetry using the latest subsea data acquisition and automated processing technologies in order to providing inspection services of subsea structures Recently photogrammetry has been used in subsea metrology
Photogrammetry dimensional control survey of a manifold Fugro 2016 . . . implement and adapt photogrammetry methodology, to overcome its main disadvantage compared to the other techniques (processing time), ensuring a complete chain that could lead to a final report in few days, wherever the structure is located Main benefits using photogrammetry are : High reactivity for photos acquisition
ASVM Provides Exceptional Images and 3D Models | Oceaneering The suitability of photogrammetry for subsea metrology was showcased by imaging passes of the seabed without the structure in view Each pass was completed in less than 30 minutes, delivering a highly efficient solution for data capture
A New Solution for Subsea Metrology | Hydro International As can be seen, only photogrammetry does not require contact with the reference measurement point This is a significant advantage for manifolds and installed subsea assets in production where metrology interface installation and onshore dimensional control surveys are not possible
Seismic acquisition and imaging services | Fugro | Fugro In offshore energy, unseen subsurface risks can delay progress and drive up costs That’s why we help you derisk shallow geohazards for your offshore wind farm and provide unique insights into subsurface structures for carbon capture, utilisation and storage (CCUS) and oil and gas
Towards real-time underwater photogrammetry for subsea metrology . . . In this paper, we investigate the use of visual-based methods, i e , methods that exploit distinctive features of the scene estimated with Visual Simultaneous Localization and Mapping (V-SLAM) algorithms, to determine and track the user position and attitude
