Abstract
En 中文
• A computer vision-based target-free method was developed for modal identification.
• The suggested approach has the advantages of simple operation, strong applicability and low cost.
• The proposed method overcomes the challenges of installing artificial targets on the structure.
• The accuracy and robustness of the proposed method are verified through laboratory and field tests.
