Abstract

To perform modal analysis, a digital 3D reconstruction of the structure under investigation is required. The acquisition and creation of such reconstructions is very time-consuming and cost-intensive, especially for performing simulations, and is mainly created manually using CAD software. Measurement-based approaches often use much simplified reconstruction models, such as line models, because of this problem. Due to the rapid development of inexpensive RGBD scanners, such as the Intel RealSense or ZED depth cameras, it is obvious to use them also for the field of modal analysis.
In this publication, the performance of these depth cameras and of algorithms for semiautomated post-processing of the 3D scans is investigated, especially for use as a reconstruction basis for finite element analysis. In addition, the 3D reconstructions are also used and evaluated in experimental modal analysis applications. Especially for the algorithms to interpolate unmeasured nodes of the reconstruction, the quality of the reconstruction plays a special role.
The whole acquisition and analysis process consists of three steps and is integrated in the WaveImage software. It starts with the acquisition of the Intel RealSense and ZED depth information (RGBD) and the following online 3D reconstruction. After the acquisition of the reconstruction, the post-processing is performed, which is applicable for beginners as well as experts. Finally, the processed reconstructions are used and validated in the software WaveImage both in the finite element and in the experimental modal analysis.
