Mise en place d'un système d’auscultation par photogrammétrie aérienne et comparaison avec un scanner laser 3D

Abstract : Through a controlled photogrammetric process, from the taking of photographs to the generation of the dense point cloud with Metashape software, the latter becomes a measuring support to carry out monitoring on structures. The M3C2 algorithm, implemented in the CloudCompare software, allows to perform displacement calculations between two pointed clouds. The inherent measurement uncertainties are considered in this calculation and allow the production of measured change for a confidence level of 95 %. The detection accuracy obtained is in the order of a few millimeters when applied to an aerial survey. This demonstrates the potential of photogrammetry as a tool of precise auscultation.
