OPTICAL 3D METROLOGY
workshop
Brescia, Italy: 12-13 December 2024
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). The past editions of O3DM were held in Strasbourg (France) in December 2019 and in Wuerzburg (Germany) in December 2022 under the umbrella of ISPRS.
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
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).

Real-time visual localisation framework for satellite-based navigation
Reliable operation of global navigation satellite systems (GNSS) for positioning, navigation, and timing (PNT) is essential for applications e.g. in communication and transport. Disruptions to GNSS threaten safety and security. The EU-funded Egeniouss project aims to enhance European GNSS services by creating an accurate, cost-effective cloud service. This service incorporates innovative multi-sensor navigation with visual localization to address GNSS challenges. Initially, it will feature an application programming interface for smartphones and drones, showcased in three case studies. Following successful validation, the service will expand for broader application.

State-of-the-art in forensic photogrammetry
Geosurveying has been used in in police investigations for several years, mostly to survey traffic collisions. In recent years optical 3D metrology has replaced typical accident surveying and has found its way in several other areas of forensic work including forensic pathology. Specifically, low-cost sensors play an important role to enable smaller police units to perform state-of-the-art incident documentation. However, optical 3D metrological data is not only acquired to document scenes and traces, but also to perform advanced reconstructions of incidents. The aim is to provide deeper insight for the court and enable more adequate judgement.

Photogrammetric techniques for crack analysis in ultra-highspeed camera image sequences
Civil engineering material testing involves various kinds of load and impact experiments on (re-inforced) concrete probes. A major goal herein is the detection of cracks. Herein, imaging techniques offer the crucial advantage of delivering precise spatio-temporally resolved information on crack positions and crack widths. In our research, we use ultra-highspeed cameras with up to 7 million frames per second to also monitor crack development and to determine crack velocities, which are in the order of 1000 m/s.

Red Hot Steel: Challenges of 3D Optical Metrology in modern steelmaking companies
Complex challenges arise from the integration of 3D optical metrology in contemporary steelmaking and metal-working operations. Contrary to expectation, the greatest difficulties do not arise from the obstacles posed by high temperatures or harsh environments requiring robust measurement solutions. Often, there's a nuanced understanding of metrology concepts, with experts struggling to distinguish between instrumental uncertainty, measurand variability and definitional uncertainty. The lecture aims to underscore the importance of technological innovation and interdisciplinary collaboration in efficiently adopting 3D optical measurement systems in modern metalworking industries.

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.
