Experimental dataset for validating TCV-RRE displacement measurements against LS-T under table excitation, free-decay, and occlusion conditions
Description
This dataset supports the manuscript related to the TCV-RRE algorithm. It contains original experimental videos, LS-T laser-reference records, table-sensor records, camera-calibration results, synchronized and cropped displacement time histories, and derived evaluation results from horizontal shaking-table tests of the TCV-RRE camera-based relative-displacement measurement method. The experiments cover harmonic excitation, earthquake excitation, free-decay vibration, and deliberate visual occlusion, together with associated ablation analyses. The machine-readable files include camera and LS-T displacement measurements, evaluation metrics, frequency-domain results, damping-identification results, active-node ratios, and the numerical data used to generate the figures and tables in the manuscript. The accompanying README describes the experimental conditions, case numbering, file correspondence, key data columns and physical units, processing stages, selected evaluation intervals, and directory structure. The implementation source code of TCV-RRE is not included.
