OPTICAL 3D METROLOGY

workshop

Braunschweig, Germany: 18-20 November 2026

- Celebrating 35 Years of Optical Metrology Workshops -

ABOUT

Optical 3D Metrology (O3DM) is a series of conferences that build on the heritage of SPIE Videometrics (1991-2017) and Optical 3D Measurement Techniques (1989-2009). Renamed as Optical 3D Metrology (O3DM), the past editions were held in Strasbourg (France) in December 2019, in Wuerzburg (Germany) in December 2022 and Brescia (Italy) in 2024 under the umbrella of ISPRS.

The 2026 edition will celebrate 35 years of optical metrology workshops!! and the primary theme of O3DM is the precise 3D measurement and accurate modelling from imaging and range sensors.

O3DM topics of interest include:

sensor investigations and characterisation
radiometric and geometric calibration of sensors
precision, accuracy and reliability issues in 3D measurements
sensor/data fusion
quality and calibration of colour for 3D models acquired by optical and range sensing techniques
algorithms for precise 3D data derivation and processing
ambiguous sequences in image orientation
hybrid adjustment
AI methods in metrology and industrial inspection
handling of transparent or reflective surfaces

O3DM is focussed on the growing interest in processing and modelling technology, and the increasing demand for accurate 3D models in applications such as industrial inspection, aerospace and automotive design, material and component testing, scene documentation, motion analysis, medicine and the exploration of remote and hazardous sites, just to name a few.

O3DM, like its predecessor events, wants to encourage the cooperation and information exchange between academia and industry in the field of optical metrology.

O3DM is an international workshop supported by the International Society of Photogrammetry, Remote Sensing and Spatial Information Sciences (ISPRS).

CONFERENCE INFORMATION & VENUE

The O3DM workshop will be held in Braunschweig, Germany, during 18-20 November 2026 at the University of Braunschweig.

O3DM will be held in conjunction with the 9th international workshop "LowCost 3D". These are two complementary scientific events, accessible with the same registration fee, that will provide delegates with a wide range of topics centred on optical 3D measurement systems and applications. Technical sessions will run in parallel among the two events and participants can join both tracks with just one registration fee.

PAPER SUBMISSIONS & PROCEEDINGS

Given the aforementioned themes, abstracts should be around 2 pages. Authors are encouraged to include figures and diagrams to illustrate the concepts and to use the ISPRS abstract template. Please send your contribution (first-author.pdf or first-author_etal.pdf) to o3dm@fbk.eu before the deadline.

Abstracts will be evaluated by the Scientific Committee and accepted contributions must then be converted into full papers in order to be published in the conference proceedings. Full papers must be formatted according to the ISPRS template and be a maximum of 8 pages. After the authors affiliations and before the keywords, please type only Technical Commission II, without any reference to a Working Group. Please send your full paper (first-author.pdf or first-author_etal.pdf) to o3dm@fbk.eu before the deadline.

The accepted full papers will be published in the ISPRS International Archives of Photogrammetry, Remote Sensing and Spatial Information Sciences.

Each submitted paper must have at least one paid registration fee in order to be published in the ISPRS Archives and have an oral presentation included in the technical sessions of the event. The ISPRS Archives are indexed in SCOPUS.

PREVIOUS CONFERENCES & VIDEOMETRICS SERIES

Sixteen Videometrics conferences were held in a series started in 1991 by Sabry El-Hakim. Under the auspices of the International Society for Optical Engineering (SPIE) from the beginning, the first conference on Industrial Vision Metrology was held in Winnipeg, Canada. Based on the success of this first venture into an emerging discipline, the conference was renamed Videometrics and held in conjunction with the SPIE Photonics East group of conferences in Boston and Philadelphia during 1992-1995.

The conference was originally focused on the metric performance of image sensors and algorithms to produce the most accurate and reliable geometric measurements and models. Topics such as sensor calibration, performance evaluation and accurate object reconstruction were predominant. It was later expanded to encompass all phases of 3D optical imaging, range imaging and modelling.

Videometrics was then re-located to become part of SPIE Photonics West, held annually in California. The conferences were held in San Diego in 1997, in San Jose in 1999 and 2001, then moved to Santa Clara in 2003 and moved back to San Jose in 2005 and 2007. The conference then became part of Optics + Photonics program track on Image and Signal Processing within the Optical Engineering and Applications conferences in San Diego in 2009. The conference was renamed to "Videometrics, Range Imaging and Applications" to reflect the changes in contemporary practice.

Throughout all of this period the attendance from North America was slowly declining, and the participation from Europe and Asia had strengthened, despite the impact of the global financial downturn. Therefore in 2011 it was decided to move the Videometrics series to Munich, Germany, to be part of the SPIE Europe conference on Optical Metrology, co-located with the World of Photonics conference and exhibition. The general theme of Optical Metrology resonated very well with Videometrics and the majority of authors and presenters from Europe confirmed the correct decision to relocate the conference. Videometrics was held in Munich in 2011, 2013, 2015 and 2017.

After the initial success in Munich, the Videometrics brand became very diluted and the character of the conference began to change. Partly because of the many conferences under the umbrella of Optical Metrology, the themes became very broad and the conference began to lose its identity. Simultaneously the attendances in the technical sessions fell away and participation from industry declined, despite the best efforts in the most recent editions to engage with industry and provide keynote speakers from the leading edge of commercial development.

Accordingly, with the support of the technical committee, the organisers made the difficult decision not to offer Videometrics, Range Imaging and Applications in 2019. Instead, the organisers and committee committed to try a new approach that is much more tightly focussed on precise 3D measurement using optical systems, with an emphasis on industry relevance. From this idea the concept of Optical 3D Metrology was born and organized under the ISPRS umbrella.

The 2026 edition will celebrate 35 years of Optical 3D Metrology workshops!
