Kraken Debuts Ultra High Def Upgrade for AquaPix Imaging Sonars

towed systems and Unmanned Underwater Vehicles (UUVs).”Kraken’s Ultra HD software improves the AquaPix SAS image resolution from 3.0 x 3.3 cm (across along track) to 1.9 x 2.1 cm and maintains constant Ultra HD resolution across the entire swath. In additions, Kraken’s advanced image processing techniques help to extract all the available information from sonar echoes.Kraken measures resolution in real-world conditions using a data-driven technique, developed by Kraken’s team of sonar scientists. The measured resolution of 1.9 x 2.1 cm includes effects such as aperture shading

MMT: Image Processing in Focus

Since the launch of its Surveyor ROV as primary tool of inspection and survey through the production of High-Resolution imagery, marine surveying firm MMT said it has taken another step forward.In a long-term collaboration, of more than a decade, between industry and academic research, MMT and Reach have conducted deep sea (up to 2,200 meters deep) high resolution photogrammetric surveys of more than sixty historically important shipwrecks in the Bulgarian Black Sea between 2016 and 2017.The Black Sea Maritime Archaeology Project (Black Sea MAP), funded by the Julia and Hans Rausing Trust and led by

then conducted a search-classify-map sidescan survey of the basin. Teledyne CARIS-Onboard, which was running on the Gavia AUV, performed mosaicing of the sidescan data in near real time while Charles River Analytics’ ATR software, also running in near real time on the Gavia AUV, used advanced image processing algorithms to analyze the CARIS mosaics and perform automatic target recognition (ATR).The coordinates of a mine-like object were passed to Marine Advanced Research’s WAM-V ASV, which moved to the provided coordinates and deployed a Teledyne SeaBotix vLBV300 remotely operated underwater

Klein's Side Scan Sonar, Then and Now

, you can do survey lines, you can have the recorder plot the survey lines, where have you been, you can go back to a spot if you found something. So there’s huge changes in the use of combination of computers and navigation with the side scan.   There has also been a lot of work on the image processing. You improve the sonar data to expand and enhance the data, and also make the equipment easier to operate.    Outside of your own technology, what one technology do you believe has had the greatest impact on allowing humans to study the oceans? MK: Whoa. It’s such a broad

New Subsea Camera Boasts 4K UHD Image Quality

because we wanted to create a camera that produced the clearest and highest quality image in the most challenging environments,” said Leonard Pool, CEO of Sidus Solutions.  The cutting-edge camera not only provides top-notch image quality but also features fully integrated automatic image processing that corrects distortion, shading and chromatic aberration. In addition, the SS490 camera has adaptive noise reduction and visibility enhancement.  Image quality was of the utmost importance to the Sidus Solutions team as they were designing the new camera, but equally as important was

IMarEST Supports Research into Collaborative Autonomous Fleets

fleet can be configured has no restrictions.   Now, with the support of the IMarEST’s Laurie Prandolini Research Fellowship, Thompson will be able to obtain additional equipment for these vehicles and extend the scope of Project FOX. These resources, such as embedded high performance 3D image processing systems; laser scanning modules; and, high resolution mono and stereo camera units will greatly improve the navigation, and environmental sensing abilities of the fleet, to a globally competitive level.   The Laurie Prandolini Research Fellowship was established in November 2011 to honor

All Eyes on Ireland

at Dublin City University (DCU) was awarded €2.4 million as part of the Beaufort Marine Research Awards and the DCU consortium developed national capacity in areas such as biosensors, analytical science, remote sensing, high-speed separations, optical sensors, biochip platforms, video imaging, image processing and information extraction. A number of follow-up investments have since been made by the Marine Institute through both joint national and EU funding calls.   In addition, the SmartOcean innovation cluster was established consolidating Irish expertise in ‘ICT for the Sea’

New Seabed Characterization Tool

bathymetric slope, roughness, TPI and any spatially distributed variable that can aid the characterization algorithm to generate classes of texture.  From that, it produces a vector polygon layer that can be exported for use outside SonarWiz. Unlike producing the analysis in a GIS or image processing package, SonarWiz performs the analysis BEFORE the data is mosaiced and geo-referenced. This reduces the impact of artifacts in the nadir and far field, which can be difficult to remove and cause unnecessary rework. Watch a demonstration here

Bert Instruments Adds Nexus USBL to Its Equipment Pool

in the U.S., Caribbean and Latin America for petroleum companies, the U.S. Department of Defense, major Universities and private companies. The company’s expertise covers both hydrographic and oceanographic surveys and is headed up by electronic engineer Humberto Guarin PhD, skilled in digital image processing and underwater acoustics, and with some 30 years’ experience the field.   For each project specialist engineers and equipment, from its own extensive stock, is assembled for the operation and to address any specific challenges to be encountered. One such project recently undertaken
