Abstract

In the field of aerospace, photogrammetry is one of the traditional technologies used to monitor deformations in components such as aircraft wings or other structures, providing valuable data for structural design and evaluation. For these kind of use cases normally two synchronized cameras are needed, they have to be separated by a certain distance to ensure good triangulation. The current challenge is to assess a new testing technology something less intrusive and less time-demanding in post-processing than photogrammetry methodology. Lidar-based techniques emerge as promising alternatives. Airbus Defence and Space has evaluated the lidar for in-flight relative positioning between two aircrafts, acquiring the knowledge, advantages, and disadvantages of this technology. The objective is to assess this new sensor to measure the flexion and torsion of a wing. This paper will explain the methodology applied to the point cloud coming from the lidar to characterize the deformation of a wing. Fusion with camera image, clustering algorithms and vibration analysis will be fundamental elements of this process. Simulation and ground tests on a wing mockup will be used to validate the methodology and will allow to choose the best configuration before flight tests.
