Flatness analysis of a swimming pool by drone
Flatness analysis: 3d modeling by photogrammetry for the inspection of a swimming pool under construction. Results obtained from 310 aerial images, post-processing by Drones Imaging.
Map of detecting flatness defects
3D modeling carried out as part of a study to control the flatness of a swimming pool under construction (with a minimum tolerance of 1cm).
Through this commercial use cas, the analysis of the 3D model made it possible to extract about ten minor deformations (holes and bumps) whose tolerance is between 1 and 2cm but also to identify two superficial 3cm depressions. In conclusion, our results showed that 97.2% of the inspected surface was perfectly flat.
