摘要
Provided is a technology for sensing anomalous tide level fluctuations to be used to monitor a tsunami, in which an estimated value of a sea surface fluctuation is obtained by conducting statistical processing or testing processing for a physical phenomenon of the tsunami displayed in image information. An anomalous tide level fluctuation sensing device according to this invention is configured to: detect a position of an object or a horizon, which fluctuates in association with a tide level, from within a video; and detect that the position fluctuates in a time cycle different from a time cycle of a tide or an ocean wave.
