To provide a track detection system capable of estimating the shape of a track in an area in which the image quality of a video camera deteriorates or an image cannot be acquired.SOLUTION: In a track detection system including imaging means provided in a vehicle traveling on a railroad track to acquire a video in front of the vehicle in a traveling direction, vehicle position detection means for detecting a position of the traveling vehicle, a database storing information on various railroad lineside facilities provided along the railroad track, and an arithmetic unit for performing image processing of the video acquired by the imaging means to enable detection of at least a portion of the track, in the database, the information on the lineside facilities are associated with position information to be stored, and the arithmetic unit acquires the information on the lineside facilities within a prescribed range in front of the vehicle from the database by using the position information detected by the vehicle position detection means, and estimates a track shape in front of the vehicle in a vehicle traveling direction on the basis of the acquired information on the lineside facilities and detected information on the track.SELECTED DRAWING: Figure 4

    【課題】映像カメラの画質が低下もしくは画像を取得することができない領域の線路の形状を推定することができる線路検出システムを提供する。【解決手段】鉄道軌道上を走行する車両に設けられ進行方向前方の映像を取得する撮像手段と、走行する車両の位置を検出する車両位置検出手段と、鉄道軌道に沿って設けられている各種沿線設備の情報を記憶したデータベースと、前記撮像手段により取得された映像を画像処理して線路の少なくとも一部を検出可能な演算装置とを備えた線路検出システムにおいて、前記データベースには、沿線設備の情報が位置情報と紐付けられて記憶され、前記演算装置は、前記車両位置検出手段により検出された位置情報を用いてデータベースより車両前方の所定範囲の前記沿線設備の情報を取得し、取得した沿線設備の情報と画像処理による線路の検知情報とに基づいて車両進行方向前方の線路形状を推定するようにした。【選択図】図4
