To provide a track identification apparatus which can detect a railroad line from a picked-up image with better accuracy.SOLUTION: A track identification apparatus comprises an image acquisition part, a feature amount selection part, a feature data derivation part, and a railroad line detection part. The image acquisition part acquires a picked-up image which is obtained by imaging a region in a direction of travel of a railway vehicle. The feature amount selection part selects one feature amount used for detection of a railroad line from plural feature amounts, which may become a measure which represents likeness of a railroad line, for each group of plural pixels in the picked-up image on the basis of prescribed criteria. The feature data derivation part derives feature data based on one feature amount, which is selected by the feature amount selection part, from each group of plural pixels. The railroad line detection part detects a railroad line from the picked-up image on the basis of the derivation result of the feature data derivation part.SELECTED DRAWING: Figure 2

    【課題】撮像画像から線路をより精度良く検出することが可能な軌道識別装置を提供すること。【解決手段】実施形態にかかる軌道識別装置は、画像取得部と、特徴量選択部と、特徴データ導出部と、線路検出部と、を備える。画像取得部は、鉄道車両の進行方向の領域を撮像することで得られる撮像画像を取得する。特徴量選択部は、撮像画像における複数の画素群ごとに、所定の基準に基づいて、線路らしさを表す尺度となりうる複数の特徴量から、線路の検出に用いる1つの特徴量を選択する。特徴データ導出部は、複数の画素群の各々から、特徴量選択部により選択された1つの特徴量に基づく特徴データを導出する。線路検出部は、特徴データ導出部の導出結果に基づいて、撮像画像から線路を検出する。【選択図】図2
