Abstract
The study of gas-liquid two-phase free surface flow is of great significance in both natural phenomena and engineering applications. This paper focuses on the application of binocular vision technology for three-dimensional reconstruction and measurement of gas-liquid two-phase surfaces. The hardware configuration, operation process, image post-processing algorithms, and key considerations of the binocular vision system are described in detail. The effectiveness of the system is verified through three specific experimental cases: solitary wave running-up and breaking, wave breaking induced by structures, and ventilated cavity around an axisymmetric slender body. The results show that the binocular vision technology can achieve high-precision three-dimensional reconstruction of gas-liquid interfaces at the laboratory scale, effectively capturing complex interface configuration. This provides reliable measuring approach for experiments in gas-liquid two-phase free surface flows.
