To accurately measure the level of water flooding on a road.SOLUTION: The water level measurement system includes: a distance sensor above a road, the distance sensor outputting a sensor signal showing the distance to the surface of the road or to an object on the road surface; a specification unit for specifying the disturbance part of the sensor signal which was acquired while a mobile body is moving under the distance sensor; a removal part for removing the disturbance part from the sensor signal; and a calculation unit for calculating the level of water flooding on the road on the basis of the sensor signal of which disturbance part has been removed.SELECTED DRAWING: Figure 4

    【課題】道路上に冠水した水の水位を精度良く測定する。【解決手段】水位測定システムは、道路の上方に設けられ、道路の路面または路面上に存在する物体までの距離を表すセンサ信号を出力する距離センサと、センサ信号における、距離センサの下を移動体が通過している期間に取得された外乱部分を特定する特定部と、センサ信号から外乱部分を除去する除去部と、外乱部分が除去されたセンサ信号に基づき、道路に冠水した水の水位を算出する算出部と、を備える。【選択図】図4
