Sea level measurement system, sea level measurement method and sea level measurement program

摘要

To provide a sea level measurement system, sea level measurement method and sea level measurement program for measuring sea level abnormality such as tsunami, applying an image measurement technology.SOLUTION: A sea level measurement system includes: photographing means 10 for photographing an image including the sea level area at the same time by a plurality of cameras installed at different points; wave extraction means 11 for extracting waves from respective images photographed at the same time by the plurality of cameras; wave association means 12 for finding the same wave from the respective images photographed at the same time by the plurality of cameras to associate the same wave with each wave extracted by the wave extraction means 11; three-dimensional information calculation means 13 for calculating the height of a sea level and the height of each wave by three-dimensionally analyzing the wave of the image associated by the wave association means 12; and sea level abnormality existenceonexistence determination means 14 for determining the existenceonexistence of sea level abnormality on the basis of the height of the sea level and the height of the wave calculated by the three-dimensional information calculation means 13.SELECTED DRAWING: Figure 4
