To provide information about rockfall.SOLUTION: A rockfall detection system is configured by: an imaging device 4 capable of imaging an area in front of a vehicle 3 and recording an imaging time; a GPS tracker 6 equipped with an atomic clock 5; transferring means 8 capable of transferring the image captured by the imaging device 4, the imaging time of the image, and positional information acquired by the GPS tracker 6 to an external terminal 7; the external terminal 7 capable of acquiring the image and the positional information transferred by the transferring means 8; rockfall extraction means 9 for extracting a rockfall by comparing a rockfall image cut out from a natural photograph as training data with the image captured by the imaging device 4, the rockfall extraction means being provided or connected to the external terminal 7; positional information acquisition means 10 for acquiring positional information of the rockfall by comparing the imaging time of the image at which the rockfall is extracted by the rockfall extraction means 9 with a time of the atomic clock 5 of the GPS tracker 6; a storage device 11 that stores the positional information of the rockfall acquired by the positional information acquisition means 10; and information providing means for displaying the positional information of the rockfall stored in the storage device 11.SELECTED DRAWING: Figure 1

    【課題】落石に関する情報提供を行う。【解決手段】車両3の前方を撮影することができ、撮影時刻を記録できる撮影装置4と、原子時計5を備えるGPSトラッカー6と、撮影装置4で撮影した画像、画像の撮影時刻及びGPSトラッカー6が取得した位置情報を外部端末7へ伝達可能な伝達手段8と、伝達手段8で伝達された画像及び位置情報を取得可能な外部端末7と、外部端末7に設けられ又は接続され、自然写真から切り抜いた落石画像を教師データとして、教師データと撮影装置4で撮影した画像とを比較して落石を抽出する落石抽出手段9と、落石抽出手段9により落石が抽出された画像の撮影時刻とGPSトラッカー6の原子時計5の時刻を照合し、落石の位置情報を取得する位置情報取得手段10と、位置情報取得手段10が取得した落石の位置情報を蓄積する記憶装置11と、記憶装置11に蓄積されている落石の位置情報を表示する情報提供手段とからなる。【選択図】図1
