OBS-3D PIM: Experiment and Explore the Different Uses of a 3D Imaging Method for Observation
2026
Following the success of the 2024 and 2025 editions, 12 students once again had the opportunity to take part in the OBS-3D PIM, supervised by Marion Jaud and Emmanuel Augereau, from 5 to 9 January 2026.
This year, despite challenging weather conditions, students were able to carry out methodological tests at IUEM, followed by field surveys (“in situ” measurements) for:
- coastal cliff monitoring at Le Grand Dellec and Porsmilin
- mapping the distribution of blue mussels at Le Petit Minou
Their supervision was also complemented by contributions from Romina Barbosa and Nicolas Le Dantec.
To conclude their project, the students wrote up their methodological protocol and designed a poster to share their experience with their peers.

ÉDITION 2025
From 6 to 10 January 2025, 12 students took part in the OBS-3D PIM OBS-3D, organised by Emmanuel Augereau and Marion Jaud from the Image and Instrumentation Unit (P2i) within IUEM. This immersive week offered participants an introduction to the world of 3D imaging, a promising technology for observational sciences.
The workshop was part of the multidisciplinary observation missions led by IUEM, focusing on the “Human–Land–Sea” continuum. Participants experimented with a 3D imaging acquisition method using low-cost devices. This approach opens up interesting perspectives for developing innovative observation strategies adapted to the diverse needs of coastal stakeholders.
Students alternated between theoretical sessions and practical applications:
- Laboratory sessions: introduction to 3D imaging technology and its scientific potential
- Fieldwork: hands-on practice of image acquisition methods, testing low-cost devices, and collecting data in real conditions
- Processing and analysis workshops: optimisation of protocols and reflection on potential applications in geomorphology, marine biology and archaeology
Beyond its technical dimension, the workshop also encouraged participants’ creativity, as they imagined a wide range of potential applications for this method while reflecting on methodological challenges. Exchanges with researchers and local stakeholders helped refine these ideas, integrating the specific needs of the relevant disciplines.
The week concluded with a collective presentation, during which students shared their work and the perspectives they had identified. They also presented their outputs at the PIM Forum on Friday afternoon.
The OBS-3D International Mobility Programme (PIM OBS-3D) enabled students to develop key skills:
- Methodological mastery: designing, testing and optimising scientific protocols
- Critical thinking: analysing the impact of tools on the quality of observations
- Applied creativity: exploring potential uses across a range of disciplines

2024
The IUEM carries out a multidisciplinary observation mission of the “Man-Earth-Sea” continuum and coordinates a number of regular, long-term measurement campaigns. Facilitating methods and the use of more ”mainstream” sensors opens up opportunities to develop new observation strategies.
In January 2024, as part of a joint interdisciplinary project (PIM), a group of Masters students from UBO, UBS and ENSTA Bretagne worked with observation professionals at IUEM on a method of acquiring 3D imagery using a low-cost device.
This PIM was like diving into the field of observation and 3D reconstruction. The students tested the method on site, and optimised and validated a protocol. They had to consider all the possible applications of this method, by meeting people involved in coastal issues (geomorphology, biology, archaeology, etc.).
