System and Method for Improving of wave prediction through combination of stereo imagery based depth retrieval and wave numerical model

摘要

The present invention monitors and calculates the depth topography of the coast through a stereo image and uses it as input data for a wave prediction numerical model to improve wave prediction accuracy. An apparatus and method for improving blue prediction accuracy, comprising: a stereo image acquisition unit that acquires a stereo image by synchronizing a shooting time of a stereo camera; A stereo image analysis unit that calculates time series data of three-dimensional sea level from the acquired stereo image ;Incident wave characteristic quantity calculation unit that calculates wave characteristic quantity at each grid position in the horizontal domain from time series data of 3D sea level; Characteristic quantity that three-dimensionally quantifies the incident wave characteristic quantity calculated by the incident wave characteristic quantity calculation unit 3D quantification unit; Inverse water depth topography prediction unit that inversely calculates coastal water depth by applying non-linear wave theory to quantified wave characteristic information calculated from stereo images; Inputs coastal water depth topography obtained from stereo image into wave numerical model It includes; a wave prediction unit that predicts a wave by using it as data.
