| Outline of Final Research Achievements |
This study proposed a concept of dynamics-based visual inspection for verifying dynamics properties of a vibrating object such as resonant frequencies and mode shapes, and systematically organized its theory and algorithm for real-time operation. We developed a high-speed vision system that can simultaneously operate image processing, modal analysis, and defect identification at 10000 fps as a sensing hardware for dynamics-based visual inspection, in which modal analysis technology and real-time high-speed vision technology are harmonized. Its effectiveness was demonstrated by showing several experimental results in crack detection in material-level test and in vibration monitoring for structure model.
