Title:
誤差算出装置および誤差算出システム
Document Type and Number:
Japanese Patent JP7042596
Kind Code:
B2
Abstract:
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
