I have a degree in engineering from the University of Cambridge and a PhD in engineering measurement from UCL
Following a period working as a land surveyor, I became involved in industrial applications of surveying and photogrammetry via an NPL-sponsored project at UCL into high-precision photogrammetry.
I subsequently spent a number of years working with Leica Geosystems (now part of Hexagon MI) on a range of industrial developments including industrial photogrammetry systems, video theodolites and laser trackers. During this time I took a break back in the UK to study for my PhD in industrial measurement at UCL.
In my final job at Leica I was responsible for the sensitivity analysis, measurement simulation and calibration strategy for the 6DOF laser tracking system. Here the calibration of the vario zoom camera was done in cooperation with Stuart Robson at UCL and his colleague Mark Shortis at RMIT in Melbourne.
Since leaving Leica I have been working independently in LVM but mostly in association with UCL. See research summary.
I work in precise 3D measurement, primarily large volume metrology (LVM) requiring sub-millimetre measurements for the manufacture and assembly of large components. However, the techniques apply at both larger and smaller scales, e.g. the built environment and coordinate measuring machines (CMMs).
My research background has included 15 years working for Leica Geosystems (now Hexagon MI) on measurement system development for industrial applications. This has included developments in industrial photogrammetry, video theodolite systems and laser trackers.
Since leaving Leica I have worked for myself and also as a researcher at UCL.
At UCL I work with Stuart Robson, Professor of Photogrammetry and Laser Scanning and currently (2021) Airbus / Royal Academy of Engineering Research Chair in LVM. This continues a long-term connection with Airbus working on topics such as state-of-the-art technology reviews, laser scanner analyses and the specification of production-line metrology.
I have also been working to develop an online knowledge base of LVM and related technologies. With UCL's support, a demonstrator was developed 2016 - 2017 which is still active at www.3DIMPact-online.com (access by permission only). A public website, explore3DM.org is due to be launched in a beta version in the second half of 2022 with the support of web and eLearning development company Marked Improvement.
I do not currently have teaching duties at UCL, although I created introductory lectures in large volume metrology, last delivered in 2004.
However, I am involved in knowledge transfer in general. Highlights include the following:
- At UCL, Stuart Robson, Jan Boehm and I work with Thomas Luhmann (Jade Hochschule, Oldenburg) on the English version of Nahbereichsphotogrammetrie. The most recent English ed. 3 was published in 2019 by de Gruyter as "Close-range photogrammetry and 3D imaging".
- I am currently working with UK web and eLearning developers Marked Improvement to create an online resource for 3D measurement and metrology called explore3DM.org. It will initially offer an extensive directory of organizations active in the field.
- I am the UCL co-organizing member of the 3D Metrology Conference (www.3dmc.events)
- I have been chair of the ISPRS Working group II/7 on Vision Metrology (with co-chairs Stuart Robson and Thomas Luhmann). As of mid-2022, this WG no longer exists.
