Detecting faults on a wing
Below is the outline of a wing with a bolt and two plates (green) that were not fitted together correctly (may require zooming in). The method we devised takes an imprecise measurement of this wing (blue) and returns an approximation of the wing (red), see Figure 1. The method also identifies the location and type of features (i.e. the bolt and misaligned plates).
The figures bellow (The spiky light blue image) illustrates how the method decomposes the measured data into a feature basis, much like a frequency decomposition. For more details click on this report .
