Vision-based vibration mode shape extraction for identifying cracks in a cantilever beam

Autor: Rongfeng Deng, Yubin Lin, Miaoshuo Li, Fengshou Gu, Andrew Ball

Publikováno v: Journal of Physics: Conference Series. 2184:012037

Taking significant merits of high spatial resolution of image sensing, the vibration mode shape of a cantilever beam (CB) is obtained from the free vibration process for local crack identification and structural health monitoring. This vision-based v

Operational Modal Analysis in the Presence of Pulse Train and Harmonics Based on SSI

Autor: Miaoshuo Li, Fengshou Gu, Fulong Liu, Andrew D. Ball, Jiongqi Wang

Publikováno v: Advances in Asset Management and Condition Monitoring ISBN: 9783030577445

Operational Modal Analysis (OMA) is a popular and effective method to identify the dynamic characteristics of a structure for Condition Monitoring (CM). It is well known that most of OMA methods are under the assumption that the excitation loads are

A Fast 3D Reconstruction Method Based on Curve Segment of Binocular Vision

Autor: Junyi Lin, Lei Wu, Yi Guo, Fengshou Gu, Andrew Ball, Kaiyong Jiang, Miaoshuo Li

Publikováno v: Advances in Asset Management and Condition Monitoring ISBN: 9783030577445

Aiming at the problem of low efficiency of the 3D reconstruction, a fast method based on piecewise quadratic curve is proposed. Firstly, a multi-line structured light binocular vision measurement system is used to obtain the two-dimensional image. Th
