Full-Field Mode Shape Identification Based on Subpixel Edge Detection and Tracking
Applied Sciences, 2023 Most research on computer vision (CV)-based vibration measurement is limited to the determination of discrete or coarse mode shapes of the structure. The continuous edge of the structure in images has rich optical features, and thus, by identifying and ...

Operational modal identification of structures based on improved empirical wavelet transform
Structural Control & Health Monitoring, 2019 This paper proposes an improved Empirical Wavelet Transform (EWT) approach for structural operational modal identification based on measured dynamic responses of structures under ambient vibrations. Two steps are involved in the improved EWT approach. In
