TRACK MATERIAL DETERIORATION DIAGNOSTIC SYSTEM
To provide a track material deterioration diagnostic system that diagnoses a deterioration state of ballast without taking the trouble to visit the actual place by analyzing a track photographic image acquired by a monitoring device.SOLUTION: In a track material deterioration diagnostic system which analyzes a deterioration state of track material based upon a track photographic image, an analyzer device comprises: area division means which utilizes known position information on a rail fastening device on a track and a value of railroad tie width to divide the track photographic image into a railroad tie area and a ballast area; binarization means which performs binarization processing to use a first threshold to discriminate pixels of the railroad tie area between white and black and then performs binarization processing to use a second threshold to binarize pixels of the ballast area; and determination means which determines an image in which the mean luminance of the pixels of the ballast area is equal to or larger than a preset predetermined value as an image including defective ballast.SELECTED DRAWING: Figure 1
【課題】モニタリング装置により取得した軌道撮影画像を解析することで、わざわざ現地に赴くことなく、バラストの劣化状態を診断する軌道材料劣化診断システムを提供する。【解決手段】軌道撮影画像に基づいて軌道材料の劣化状態を解析する軌道材料劣化診断システムにおいて、解析装置は、既知である軌道上のレール締結装置の位置情報および枕木幅の値を利用して前記軌道撮影画像から枕木領域と道床領域を分割する領域分割手段と、枕木領域の画素を第１の閾値を用いて白色または黒色に弁別する二値化処理を行い、道床領域の画素を第２の閾値を用いて二値化処理を行う二値化処理手段と、道床領域の画素の平均輝度が予め設定された所定値以上である画像を道床に不良があると判定する判定手段とを備えるようにした。【選択図】図１
