Error evaluation of binocular vision method for reconstructing breaking wave surface
文献摘要：
Quantization error and its source of the binocular stereo vision technique are evaluated by measuring breaking wave surface in wave flume.The verification test focuses on the run-up process of a breaking solitary wave on a slope.The three-dimensional topography of the free surface is reconstructed at three representative stages of wave propagation.The two-dimensional profile from the side view and statistical data are used to evaluate the quantization error.The breaking degree of wave surface has a mild influence on the performance of stereo reconstruction in the current configuration.The mean error of detecting the surface elevation is about 2 mm,around 0.1％of the measurement distance.Sixty percent of the error comes from the deficient match in image interrogation,and the remaining forty percent arises from the limited system configuration.The precise stereo measurement of the breaking surface shows that the present binocular vision system provides a new technique in experiments in hydrodynamics with the breaking surface.
