Binocular vision measurement and its application in full-field convex deformation of concrete-filled steel tubular columns
TL;DR: In this article, the least square-based circle-fitting algorithm was applied to binocular vision systems for the static and dynamic collection of full-field 3D deformation data in concrete-filled steel tubular columns.

Vibration and modal analysis of a rotating disc using high-speed 3D digital image correlation
TL;DR: In this paper, the authors used high-speed digital image correlation in vibration analysis of rotating structures and showed that the elimination of rigid body motions leads to a higher accuracy of measurement and provides more pronounced frequency response spectra.
Journal ArticleDOI
Model updating of uncertain parameters of carbon/epoxy composite plates using digital image correlation for full-field vibration measurement
TL;DR: In this paper, the results obtained by applying these alternative techniques are compared, to obtain physically-sound models of carbon/epoxy composite plates, and the experimental setup has been benchmarked using two different sets of plates varying thickness and ply stacking.

Vibration measurement using a pseudo-stereo system, target tracking and vision methods
Thomas Durand-Texte,Thomas Durand-Texte,Elisabeth Simonetto,Stéphane Durand,Manuel Melon,Marie-Hélène Moulet +5 more
TL;DR: A single high-speed camera pseudo-stereo system, with a four-mirror adapter, is optimised thanks to simulation, in order to measure vibrations, to study the relevance and potential limitations of the approach applied to an electro-acoustic source: a low-frequency loudspeaker.

A robust line-tracking photogrammetry method for uplift measurements of railway catenary systems in noisy backgrounds
TL;DR: The accuracy, robustness and applicability of the proposed tracking method are demonstrated through numerical experiments, the field uplift measurement of the railway catenary system and the identification of the contact wire in a diverse city environment.

The modal assurance criterion–twenty years of use and abuse
TL;DR: A review of the development of the original modal assurance criterion (MAC) together with other related assurance criteria that have been proposed over the last twenty years can be found in this paper.
Parameter estimation from frequency response measurements using rational fraction polynomials (twenty years of progress)
Dave Formenti,Mark Richardson +1 more
TL;DR: In this article, the authors present a new formulation that overcomes many of the numerical analysis problems associated with an old least squared error parameter estimation technique, which has made this technique feasible for implementation on mini-computer based measurement systems.
