Abstract

In order to achieve high-efficiency vibration measurement of non-contact and large field of view of flexible cantilever

a flexible cantilever beam vibration displacement measurement system is designed based on the binocular vision principle. A marker point is attached to the end of the flexible cantilever beam

and the binocular camera measures the vibration displacement image sequence of the marker point to realize the indirect measurement of the vibration displacement of the flexible cantilever beam. By comparing the experimental results with the simulation results

the validity and accuracy of the experimental measurement results are verified.
