Title:
FLOODING PREDICTION DEVICE, FLOODING PREDICTION SYSTEM, AND FLOODING PREDICTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/172405
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a flooding prediction device, etc. that make it possible to accurately predict the occurrence of flooding of a river. A flooding prediction device (2) is provided with: a measurement data acquisition means (11) for acquiring measurement data indicating the result of measurement based on irradiation laser light emitted by a coherent light sensing device (1) and radiated onto a measurement target region including the water surface part of a river, and reflection laser light reflected by the measurement target region and received by the coherent light sensing device (1); a three-dimensional point group model generation means (12) for generating a three-dimensional point group model of the measurement target region by using the measurement data; a water surface state information generation means (13) for generating, by using the measurement data and the three-dimensional point group model, water surface state information indicating the state of the water surface part in the measurement target region; and a flooding prediction means (14) for predicting the occurrence of flooding of the river by using the water surface state information.
