The present invention provides a tidal current information display device for a moving body that displays tidal current information on a display screen, and an AR navigation system using the tidal current information display device. A power flow display data generation device for a moving body that displays power flow information on a display screen, the power flow display data generation device comprising: a power flow information reception unit that receives power flow information from the moving body; receiving tidal current information of a plurality of predicted tidal current directions including a position of a tidal current on a nautical chart of an area including a moving body (ship or the like) and the tidal current at the position at a plurality of corresponding times; and a power flow display data generation unit that generates an indicator including a time scale determined on the basis of a plurality of times, determines the position of each predicted power flow direction on the time scale at each time, generates a plurality of symbols indicating each predicted power flow direction at each time at each position on the time scale, and displays the generated symbols on the basis of the time scale. An indicator including a plurality of symbols is output to a display screen.
本发明提供将潮流信息显示在显示画面上的移动体的潮流信息显示装置、以及使用了该潮流信息显示装置的AR导航系统。一种将潮流信息显示在显示画面上的移动体的潮流显示数据生成装置,其中,该潮流显示数据生成装置具有:潮流信息接收部,接收包括包含移动体(船舶等)的区域的海图上的潮流的位置和在对应的多个时刻的该位置的潮流的多个预测潮流方向的潮流信息;以及潮流显示数据生成部,生成包含基于多个时刻而确定的时间标度的指示符,确定各个时刻的时间标度上的各个预测潮流方向的位置,在时间标度上的每个位置处、生成多个表示各个时刻的各个预测潮流方向的符号,将包含多个符号的指示符输出至显示画面。
