Real-time target alignment system for high-power high-repetition rate laser operations using a five degree-of-freedom hybrid mechanism (2020)
Journal Article
Karim, S., Piano, S., Branson, D., Santoso, T., Leach, R., & Tolley, M. (2022). Real-time target alignment system for high-power high-repetition rate laser operations using a five degree-of-freedom hybrid mechanism. International Journal of Control, 95(4), 867-885. https://doi.org/10.1080/00207179.2020.1827297

This paper presents a real-time position control solution for the targets used in the high-repetition rate laser operations of large-scale high-power laser facilities. The design of the control system is based on an Abbe-compliant, in-process positio...

Optimisation of camera positions for optical coordinate measurement based on visible point analysis (2020)
Journal Article
Zhang, H., Eastwood, J., Isa, M., Sims-Waterhouse, D., Leach, R., & Piano, S. (2021). Optimisation of camera positions for optical coordinate measurement based on visible point analysis. Precision Engineering, 67, 178-188. https://doi.org/10.1016/j.precisioneng.2020.09.016

In optical coordinate measurement using cameras, the number of images, and positions and orientations of the cameras, are critical to object accessibility and the accuracy of a measurement. In this paper, we propose a technique to optimise the number... Read More about Optimisation of camera positions for optical coordinate measurement based on visible point analysis.

Volumetric error modelling of a stereo vision system for error correction in photogrammetric three-dimensional coordinate metrology (2020)
Journal Article
Isa, M. A., Sims-Waterhouse, D., Piano, S., & Leach, R. (2020). Volumetric error modelling of a stereo vision system for error correction in photogrammetric three-dimensional coordinate metrology. Precision Engineering, 64, 188-199. https://doi.org/10.1016/j.precisioneng.2020.04.010

Optical three-dimensional coordinate measurement using stereo vision has systematic errors that affect measurement quality. This paper presents a scheme for measuring, modelling and correcting these errors. The position and orientation of a linear st...
