A106 ステレオ画像を用いた波面計測

抄録

It is important to grasp water surface profile when we discuss various phenomena in coastal zone. For example, sediment transport and rip current are determined mainly by the spatial distribution of waves in surf zone. Measurement of sea waves using Euler's method is a general. However it is difficult to determine spatial distribution of waves. We had measured wave profile using experimental water tank without tracers or targets. We generated a few kinds of regular waves and took the pictures by two digital cameras and analyzed the azimuth difference in digital images by stereo matching method.
