Development of multi-view 3D reconstruction system for bubble flow measurement

Year: 2024

Type: article

Abstract: This work introduces a development of bubble measurement method utilizing three-dimensional (3D) reconstruction technique from multi-view images. Multiple synchronized cameras were positioned around a water container, and calibration was performed to obtain camera parameters. Images of bubbles emerging from a nozzle were captured, and a machine learning technique was used to extract bubble silhouettes. These silhouettes were then projected onto a 3D voxel space using the visual hull method. It was confirmed that the method can successfully capture bubble generation, detachment, and rise behaviors, offering insights into understanding bubble dynamics and potential applications in 3D computational fluid dynamics validation. The method is easy and cost-effective to install and can be applied to flexible setups.
