Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Review Description
High-accuracy panoramic three-dimensional (3D) dynamic deformation measurements are of considerable significance for studying the mechanical properties of large or ultra-large structures. As a simple, non-contact, and high-precision full-field deformation measurement technology, three-dimensional digital image correlation (3D-DIC) can provide an effective measurement method for large-scale structural deformation measurement. This paper introduces the basic principles of 3D-DIC measurement and presents key technical advancements in the panoramic deformation measurement of large structures with multiple cameras. These advancements include large-scale speckle fabrication, 3D calibration of large field-of-view, coordinate unification of multi-camera systems, and real-time calibration of camera extrinsic parameters. Furthermore, this paper presents practical applications of high-accuracy 3D dynamic deformation measurements for large structures in civil engineering and aerospace engineering fields, such as the assessment of the cassette structure in seismic shaking table tests, panoramic high-speed deformation measurement of suspension cable dome structures in progressive collapse tests, and panoramic deformation measurement of cabin structures of launch vehicles in load tests. Using high-accuracy 3D dynamic deformation measurements for large structures provides a reliable experimental method for seismic performance analysis, mechanical modeling of large structures, and in-depth study of failure mechanisms.
