Abstract
There are many methods for beam-like structures’ vision-based damage detection, usually based on deflection shape analysis. However, most engineering structures have geometries for which such a straightforward damage detection approach is not feasible. This paper introduces the Aligned Marker Space (AMS) method to close this gap and allow using straightforward deflection-difference-based damage detection methods for various civil engineering structures. The method involves transforming vision data into a new morphed space to straighten complex geometries along one dimension. Data transformed using this approach can be used as an input to various damage detection algorithms, including local (e.g., second-derivative-based or wavelet-based algorithms) and global approaches (e.g., trend detection and line-segments method). The method is verified based on data acquired in numerical simulations and in a set of practical experiments. A Blender-based approach is used to build plausible simulated data with a high resemblance to real-life examples. These examples are then validated using complex geometries in a series of physical experiments under laboratory conditions.
