Stereoscopic High Speed Camera Based Operational Modal Analysis using a One-Camera Setup

Описание к видео Stereoscopic High Speed Camera Based Operational Modal Analysis using a One-Camera Setup

In this study, we demonstrate a very simple setup that enables 3D measurements of a vibrating structure with only one single high-speed camera using a mirror to generate a stereoscopic image. Using a very specific viewing angle and making some simplifying assumptions, the 3D displacement reconstruction is very easy and doesn't require camera calibration procedures as usually used for similiar tasks.
The measurement results are used for an output-only modal analysis of the structure which yields mode shapes that look as expected, so the general approach could be validated.

The work was presented at the conference IMAC-XL. The content is published in the conference proceedings.
