Photogrammetry and optical methods in structural dynamics – A review
TL;DR: In this paper, the most current trends in the photogrammetry technique (point tracking, digital image correlation, and target-less approaches) are reviewed and compared to other measurement techniques used in structural dynamics (e.g., laser Doppler vibrometry and interferometry).

Blind identification of full-field vibration modes from video measurements with phase-based video motion magnification
Yongchao Yang,Charles Dorn,Tyler Mancini,Zachary Talken,Garrett T. Kenyon,Charles R. Farrar,David Mascareñas +6 more
TL;DR: In this article, a multi-scale image processing method is applied on the frames of the video of a vibrating structure to extract the local pixel phases that encode local structural vibration, establishing a full-field spatio-temporal motion matrix.
Journal ArticleDOI
Comparison of DIC and LDV for practical vibration and modal measurements
TL;DR: In this paper, the authors compare laser Doppler vibrometry (LDV) and digital image correlation (DIC) for use in full-field vibration and modal testing.
Journal ArticleDOI
Frequency response functions of shape features from full-field vibration measurements using digital image correlation
TL;DR: In this paper, an adaptive geometric moment descriptor (AGMD) is proposed to extract shape features from a series of full-field transient responses under random excitation, and the obtained shape features are demonstrated to be succinct and efficient.
