The present invention provides a method for extracting features of the nearshore wave breaking process based on
time series video images; wherein, the method comprises: setting at least one pixel sampling area in a plane
geographic coordinate system, collecting
time series video images of ocean nearshore
waves, quickly converting them into plane geographic coordinate images through a coordinate model, and then stacking cross-
shore pixel values of several pixel sampling areas within a set time to generate a cross-
shore pixel value and time relationship
sequence diagram, mining the time-varying
signal of the wave propagating toward the
shore, combining the geometric relationship between the
camera angle of view and the plane projection of the wave breaking, and calculating key wave breaking features such as the wave
breaking point position, wave breaking
water depth, and wave breaking height; the method can continuously monitor the nearshore wave breaking features efficiently, automatically, and stably, effectively making up for the shortcomings of traditional monitoring and analysis methods, and providing strong
technical support for the refined research and management of nearshore beach dynamic landforms.
