To address the challenge of identifying micro-vibrations in offshore wind turbines
this study proposes a novel visual recognition methodology integrating phase-based motion magnification (PBMM) and template matching (TM)
herein referred to as the PBMM-TM framework. This paper utilizes a scaled-down model of the NREL 5 MW wind turbine to systematically evaluate the influence of parameters such as illumination
resolution
and background contrast on the precision of dynamic characteristic identification under micro-vibration conditions. The efficacy of the PBMM-TM method under adverse environmental conditions is rigorously analyzed
and its applicability is further corroborated by field measurements obtained from a wind turbine situated in Zhuhai
China. Results demonstrate that the PBMM-TM algorithm can accurately capture and identify dynamic structural parameters
even with minimal vibration amplitude. Compared to traditional methods
this approach enhances recognition accuracy by nearly 50% in low-light and low-contrast settings. The algorithm also maintains accurate feature point tracking at low resolutions
enabling efficient long-range monitoring of offshore wind turbines.
