Method for estimation of bathymetry using hyperspectral image

摘要

The present invention relates to a method for estimating water depth using a hyperspectral image, specifically, by using a hyperspectral image to obtain a hyperspectral image using an unmanned aerial vehicle, and then setting a regression equation using a band ratio, thereby providing high accuracy only with a hyperspectral image. The topography that can estimate the water depth using the estimated water depth and obtain the elevation of the river bed to survey the topography, as well as provide each method according to the range and level of measuring the topography of the river. It is about measurement methods.
