| description | To provide an error calculation device capable of highly accurately grasping an error between an actual stop position when a train stops at a station and a predefined target stop position.SOLUTION: An error calculation device 10 is provided with an acquisition unit 102, an identification unit 103 and a calculation unit 104. The acquisition unit acquires a captured image from an imaging device installed in a train. The identification unit identifies a marker set at a station where the train stops from the captured image. The calculation unit acquires a difference between the position of a prescribed part in the identified marker in the captured image and a reference position which is the position of a prescribed part in the captured image captured in advance when the train stops at a predefined target stop position, and calculates an error between the stop position and the target stop position of the train on the basis of the difference.SELECTED DRAWING: Figure 2
【課題】列車が駅に停車した際の実際の停止位置と、予め定められた目標停止位置との誤差を高精度に把握する誤差算出装置を提供する。【解決手段】誤差算出装置１０は、取得部１０２と、特定部１０３と、算出部１０４とを備える。取得部は、列車に設置された撮像装置から撮像画像を取得する。特定部は、列車が停止する駅に設置されたマーカーを、撮像画像から特定する。算出部は、特定されたマーカー内の所定部位の撮像画像における位置と、列車が予め定められた目標停止位置に停止した際に予め撮像された撮像画像における所定部位の位置である基準位置と、の差分を求め、差分に基づいて、列車の停止位置と目標停止位置との誤差を算出する。【選択図】図２ |
