Report on the 1st virtual meet-up event of the ISPRS WGII/9 – Underwater Data Acquisition and Processing, 8-9 June 2021
July 13, 2021
The 1st virtual meet-up event of the ISPRS WGII/9 – Underwater Data Acquisition and Processing, took place on 8-9 June 2021. It was jointly organized by Fabio Menna (Bruno Kessler Foundation), Mark Shortis (RMIT University), Dimitrios Skarlatos (Cyprus University of Technology) and Panagiotis Agrafiotis (National Technical University of Athens).
In the event, which attracted many new members to register to the working group, participated 83 out of 113 members registered on the WG webpage. The event provided an update on the research activities of the WGII/9 members by hosting 34 presentations (final program here), followed in 21 different countries around the globe. An informal but very informative discussion was also held using SLIDO. Questions were answered live by the speakers. Also, the SLIDO Q&A was kept open after the sessions and participants continued the discussion even after the live event, showing again a strong interest in the topics of the WG.
Photogrammetry was the main research area of the participants representing 71% of them for both days while Computer Vision, Camera Calibration and Surveying were following with percentages between 48-40%. Participants specializing in Robotics represented the 30% of the participants while experts in Engineering, Hydrology, Oceanography, Navigation, Geology, Archaeology, Biology and the industry participated too. The SLIDO Q&A indicated also that the vast majority of the participants is highly interested in benchmark datasets related to the scientific areas of the research group, however, most of them are not able to deliver any data. This triggered a data collection and sharing initiative by the WG that will be soon published in the WG’s webpage.
WGII/9 – Underwater Data Acquisition and Processing virtual meet-up event on 8-9 June 2021
May 5, 2021
The WGII/9 working group chairs would like to invite you to the ISPRS WGII/9 members virtual meet-up on 8-9 June.
The event is open to the members of the working group and to anyone who shares the same passions and interests for our research topics and mission. New members are therefore welcome to join the working group and participate in the event.
The main aim of the virtual meet-up is to give anyone the opportunity (if they like) to present themselves and their research group through a short pitch presentation (2-3 mins max) related to the ISPRS WGII/9 topics.
For those who are very enthusiastic about it and want to provide a deeper dive into their projects, research experiences and outcomes, please send us an abstract of the talk (max 7-10 minutes) possibly with some figures. We will do our best to guarantee to anyone room for sharing their experiences.
To facilitate the participation across different countries and time zones we will try to find hours that maximize the attendance. That is why we will split the meeting in two different days with a maximum duration of 4 hours per day (depending on the number of registrations ). Being together in the same moment across the world will of course require some flexibility. The tone of the event is very informal, therefore feel free to put yourself at ease anywhere you like and enjoy the meeting.
To participate in the event a registration is mandatory, so please send an email to firstname.lastname@example.org before May 31st to let us know if you would like to participate with a pitch presentation or give a longer talk.

2nd International Workshop ISPRS/CIPA workshop UNDERWATER 3D RECORDING & MODELING
May 15, 2019
The 2nd UNDERWATER 3D RECORDING & MODELING workshop supported by ISPRS and CIPA, was held at Cyprus University of Technology facilities in Limassol, Cyprus from May 2nd to the 3rd, 2019. The organizing committee was Dimitrios Skarlatos (Cyprus University of Technology), Panagiotis Agrafiotis (Cyprus University of Technology and National Technical University of Athens), Marinos Vlachos (Cyprus University of Technology), Erica Nocerino (AMU Marseille and ETH Zurich), Fabio Menna (COMEX Innovation) and Fabio Bruno (University of Calabria and 3D Research srl.). The workshop was sponsored by 3D Research s.r.l., iMARECULTURE H2020 EU project, COMEX Innovation and Geosysco Ltd., which had booths demonstrating services and equipment.
The workshop was attended by 56 individuals from 13 different countries. Of the 33 submitted abstracts, 26 were selected for publication, 19 for presentation, and 7 for posters. Three keynote speakers set the tone for the topics throughout the conference. Rafael Garcia and Nuno Gracias from the University of Girona, (Underwater Vision and Robotics group) started the conference off presenting the current state of the art in Omnidirectional Underwater Computer Vision Research and Applications at the University of Girona. The next day, Fabio Bruno from University of Calabria and 3D Research srl. presented his speech on “Exploring underwater sites through virtual and augmented reality”. The selected papers for publication are published in The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences under Volume XLII-2/W10, 2019.
The workshop was a success, as was noted by the attendance right up until the last paper was presented. The decrease in number of participants, in comparison to the equivalent event in 2015 at Sorrento, is not related to decrease in interest in the topic of precise underwater 3D modelling, as there is an increasing number of versatile applications, such as biology, engineering, ecology, archaeology, VR, etc.

3D ARCH 2017 - Special Session
February 01, 2017
UNDERWATER 3D RECORDING & MODELING session at 3D-ARCH 2017 - Nafplio, Greece 1 - 3 March
the session follows the ISPRS/CIPA Workshop "Underwater 3D recording & Modeling" held in 2015 in Piano di Sorrento.
3D-ARCH is a series of international workshops which started in 2005 in Venice and move throughout the years to Zurich (2007), Trento (2009, 2011, 2013) and Avila (2015), organized as an ISPRS and CIPA event.
February 2, 2017
3D Modeling and Interpretation for Underwater Archaeology was held at Flinders University in Adelaide, South Australia during 24-26 November 2016. The workshop was sponsored by UNITWIN, ISPRS and some industry organisations. UNITWIN is a UNESCO initiative to promote inter-university cooperation in fields of relevance to UNESCO.
This workshop brought together leading international experts and experienced practitioners working in 3D applications for underwater archaeology. The majority of speakers and participants were archaeologists from Europe, Asia and Australia who were using a variety of mapping techniques, including photogrammetric, acoustic and lidar. Many of the presentations demonstrated the effectiveness of Structure from Motion solutions, but also identified some of the challenges to ensure accurate and complete 3D models.
The organisers are planning a book containing the highlights from the workshop, to be published in late 2017 or early 2018.
