To provide a submergence detection device capable of detecting a submergence degree on a road to which an underpass structure is applied without depending on a traveling state of a vehicle.SOLUTION: There are provided an image acquisition unit for acquiring a picked-up image obtained by imaging an underpass with an imaging device fixedly arranged at a position capable of imaging at least a slope part of the underpass; a water surface detection unit for detecting a water surface line connecting the underpass and a contact point with a water surface in a submergence area in the underpass on the picked-up image, based on the picked-up image acquired by the image acquisition unit; and a water depth determination unit for determining a water depth on the submergence area, based on the water surface line detected by the water surface detection unit.SELECTED DRAWING: Figure 1

    【課題】アンダーパス構造が適用された道路において、車両の走行状態によらず、冠水の程度を検知することが可能な冠水検知装置を提供する。【解決手段】アンダーパスの少なくとも斜面部を撮像可能な位置に固定的に設置された撮像装置が当該アンダーパスを撮像した撮像画像、を取得する画像取得部と、画像取得部が取得した撮像画像に基づき、当該撮像画像上にて、アンダーパスと当該アンダーパスにおける冠水領域の水面との接点、を結ぶ水面線、を検出する水面検出部と、水面検出部が検出した水面線に基づき、冠水領域の水深を判定する水深判定部とを備えた。【選択図】図1
