Accurately measuring the near-field wave evolution around structures is a crucial prerequisite for studying wave-structure interactions.For focused wave tests on a fixed square column,a near-field wave measurement method based on stereo vision is proposed.A marker-net made of lightweight foam particles is used to mark the wave surface to obtain the images with sufficent texture.A binocular system is arranged in front of and behind the column to comprehensively cover the surrounding area,reconstructing the three-dimensional wave field around the column in focused wave-column interaction.The three-dimensional evolution of wave run-up is studied from the perspective of spatial distribution.Wave time histories extracted from the continuous image sequences show good agreement with the measurements from wave probes.The results indicate that the stereo vision method can accurately reconstruct the near-field wave evolution around the square column and measure wave run-up under extreme waves.
