CONTINUOUS MEASUREMENT METHOD FOR ENTIRE VISIBLE REGION OF CELESTIAL SPHERE
To provide a continuous measurement method for the entire visible region of a celestial sphere that enables accurate rail temperature prediction according to the current situation based on the visible area that shows a boundary of a building at each point along a railroad track that were collected uniquely, instead of geographic data obtained from a geographic information system.SOLUTION: A continuous measurement method includes: a coordinate setting step of setting coordinates of at least two on-vehicle cameras C1, C2 mounted on a vehicle 10 traveling on a railroad track; a peripheral information collection step of obtaining azimuth angle data and elevation angle data of peripheral objects from image data taken by the at least two on-vehicle cameras C1, C2 mounted on the vehicle 10; and a visible region calculation step of calculating a visible region indicating the boundary of peripheral objects based on camera coordinates set in the coordinate setting step, the azimuth angle data (azimuth angle indicated by a symbol φ in a formula) of the peripheral objects at respective points along the railroad track, and the elevation angle data (elevation angle indicated by a symbol h in the formula) collected in the peripheral information collection step.SELECTED DRAWING: Figure 2
【課題】地理情報システムから得る地理データに代えて、独自に収集した線路沿いの各地点の建物の境界を示す可視領域に基づき、現状に即した正確なレールの温度予測を可能とする全天可視領域の連続測定方法を提供する。【解決手段】線路を走行する車両１０に搭載した少なくとも２台の車載カメラＣ１，Ｃ２の各座標を設定する座標設定工程と、車両１０上の少なくとも２台の車載カメラＣ１，Ｃ２により撮影した画像データから周辺物の方位角データ及び仰角データを得る周辺情報収集工程と、前記座標設定工程で設定されたカメラ座標と、前記周辺情報収集工程で収集された線路沿いの各地点の周辺物の方位角データ（数式に符号φで示す方位角）及び仰角データ（数式に符号ｈで示す仰角）とに基づき、当該周辺物の境界を示す可視領域を演算する可視領域演算工程と、を有することを特徴とする。【選択図】図２
