Using binocular vision to measure wave characteristic

The paper presented a new wave acquisition stereo system to estimate significant wave height based on stereo (binocular) vision. Using binocular vision, wave transformation in near shore water can be measured in wave altitude. The total measurement numbers are 1024 times. Wave vertical altitudes can be extracted from the datum according to binocular vision. With the help of 3D Fourier transform, the wave surface data can be turned into wave spectrum. By analyzing the wave spectrum, significant wave height can be estimated. Experimental results have shown that the method is effective.
