To provide an alarm system capable of sharing highly accurate hazard information among a plurality of operating vehicles.SOLUTION: An alarm system 1 is comprised of: a first on-vehicle device 2 having a camera 4 as an imaging unit that images an outside of a first vehicle V1, a detection unit 20A that detects a predetermined image which is an image imaged by a road marking or a road sign from the image data imaged by the imaging unit, a first transmission unit 20C that transmits a predetermined image and an imaging position to the outside when it is determined that a portion of the predetermined image is a high-risk portion based on traveling data of the first vehicle, a determination unit 70A, 70B that performs image recognition for the predetermined image and saves it as a risk portion when it is determined that the detection by the detection unit is correct, and a second transmission unit 70C that transmits the risk portion; and a second on-vehicle device 8 mounted on a second vehicle V2, which issues an alarm when the vehicle is operated based on the risk portion and the position of the second vehicle.SELECTED DRAWING: Figure 1
【課題】精度の高いハザード情報を複数の運行車両で共有することが可能な警報システムを提供する。【解決手段】警報システム1は、第一の車両V1の外部を撮像する撮像部としてのカメラ4と、撮像部によって撮像された画像データから、道路標示または道路標識が撮像された画像である所定画像を検出する検出部20Aと、第一の車両の走行データに基づいて所定画像の箇所が危険性の高い箇所であると判定した場合に、所定画像および撮像位置を外部に送信する第一送信部20Cと、所定画像に対する画像認識を行い、検出部による検出が正しいと判定した場合に危険箇所として保存する判定部70A、70Bと、危険箇所を送信する第二送信部70Cと、を有する第一車載器2及び第二の車両V2に搭載され、危険箇所と、第二の車両の位置と、に基づいて車両運行の際に警報を発する第二車載器8と、を備える。【選択図】図1
