DEVICE AND METHOD FOR ANALYSIS OF VIBRATIONS USING HIGH-SPEED VIDEO DATA AND APPLICATION OF SUCH DEVICE FOR NON-CONTACT ANALYSIS OF VIBRATIONS

摘要

The present disclosure generally relates to the field of vibration analysis. More specifically, the present disclosure relates to a technique for modular high-speed video vibration analysis of a structure. An embodiment of a device for high-speed video vibration analysis comprises a camera arrangement adapted to generate at least two high-speed video streams of the structure and a data analyzer unit, connected to the camera arrangement. The data analyzer unit comprises a processing unit that is adapted to extract vibrational data of at least a portion of the captured structure by considering estimated deformations of at least a portion of the captured structure along a first plane and determined depth information of at least a portion of the captured structure along a second plane that is different from the first plane or along an axis included in the second plane.
