Abstract
Stereo imagery of the sea surface is one of the most effective tools for remote sensing wind waves with lengths of half a meter or more. In this paper, we propose a new method for using a series of stereo images to reconstruct the wind ripple velocity field on a long surface wave profile. The presented method is based on detecting characteristic structures on the sea surface (short wind waves, breaking waves, foam, etc.), determining their displacement between two adjacent frames (similarly to the Particle Imaging Velocimetry - PIV method), and recalculating estimated displacement from frame coordinates into three-dimensional world coordinates through projection onto a long wave profile obtained using stereo pairs. The test results on the data of stereo imagery of the sea surface carried out from a stationary oceanographic platform in the Black Sea in 2021 are presented in this paper too.
