| Research Abstract |
Over the past decade, a considerable number of studies have been conducted on the wave plane distributions by using two video camera images. These studies analyzed azimuth difference of digital images taken by video cameras. The problem of these studies is to find the same element between two images. Generally, they put the targets or tracers in images to solve azimuth difference. This way which comes from Particle Image Velocimetry (PIV) method, is sufficiency to measure waves. However, this method involves difficulties to put the appropriate number of targets or tracers on water surface evenly, which is not reasonable to measure sea 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.
