Abstract:
Advancements in three-dimensional flow velocimetry techniques, such as Shake-The-Box (STB), have significantly improved volumetric reconstruction of flow fields when an object is outside the field-of-view. However, accurately reconstructing flow around moving objects remains challenging due to occlusions and the potential introduction of ghost particles within the object domain, particularly when the object geometry is not a canonical case. In this study, we propose an artificial intelligence (AI)-based approach to reconstruct 3D objects in volumetric PIV/PTV experiments that relies on original calibration and camera image segmentations.
