Abstract

The in-house validation of finite element models for bird strike events is currently carried out by means of experimental tests on flat plates. High displacement speeds in these experiments require a low exposure time of the high-speed camera (up to 1/50,000 s). In order to acquire images of sufficient quality, a special, high-intensity light source has to be used, which does not always turn out to be possible. Therefore, the regions with high displacement speeds often result in blurry images. In such cases, a printed line pattern to estimate the shape of the plate during the test, offers major advantages over a speckle pattern in terms of the reconstruction and optimization of the blurry regions. In this article, a stereo vision technique is presented that was developed to reconstructs 3D shape maps using images of impacted plates with printed line patterns. It is shown that two cameras are necessary to calculate accurate shape maps in case of large deflections. The resulting shapes can be used for the validation of numerical simulations.

Notes

  1. The cruise speeds of commercial aircraft are typically 878–926 km/h

  2. A simplex is the n-dimensional equivalent of the triangle in 2D. To construct a simplex in a n-dimensional solution space, n + 1 values are therefore needed.
