| 内容記述 | This paper presents a new innovative method for measuring two dimensional water surface configurations. This method uses a pair of sequential images captured by two high-resolution CCD cameras arranged in a stereo position. The idea of the method is to make the water colour white so that the instantaneous water surface appears like a solid surface with a clear pattern when an irregular pattern of light is projected onto it. It should be noted that this method is suitable to measure waves with small amplitude accurately and at the same time discontinuous surface robustly. At first, we explain the measurement principal and the experimental procedure for obtaining stereo images. Secondly, we examine the measurement accuracy by applying our technique to calibrated wavy plates. In the application of the technique to actual flow fields, we first measure surface waves and ripples generated in a shallow water box, and show that we can trace the propagation of small waves as small as 1mm. In another application, we measure periodic surface fluctuation generated at an asymmetric cavity installed in an open-channel flow, demonstrating robustness of the technique applicable even when a discontinuous surface with wave breaking is presented in the course of the measurement. | |||||||||
