To provide an information processing device, etc., capable of improving the estimating accuracy of a self-position in a vessel.SOLUTION: The information processing device has predicted position acquisition means, estimated position calculation means, state information acquisition means, and speed calculation means. The predicted position acquisition means acquires a predicted position of a vessel. The estimated position calculation means calculates an estimated position of the vessel in which the predicted position is updated on the basis of collation between data based on an output of an external sensor provided in the vessel and map data. The state information acquisition means acquires state information of the vessel. The speed calculation means calculates a speed of the vessel at a first processing time on the basis of the estimated position at the first processing time, the estimated position at a second processing time immediately before the first processing time, and a time constant set on the basis of the state information.SELECTED DRAWING: Figure 22

    【課題】船舶における自己位置推定の精度を向上させることが可能な情報処理装置等を提供する。【解決手段】情報処理装置は、予測位置取得手段と、推定位置算出手段と、状態情報取得手段と、速度算出手段と、を有する。予測位置取得手段は、船舶の予測位置を取得する。推定位置算出手段は、船舶に設けられた外界センサの出力に基づくデータと地図データとの照合に基づき、予測位置を更新した船舶の推定位置を算出する。状態情報取得手段は、船舶の状態情報を取得する。速度算出手段は、第1処理時刻での前記推定位置と、第1処理時刻の直前の第2処理時刻での前記推定位置と、状態情報に基づき設定した時定数とに基づき、第1処理時刻での船舶の速度を算出する。【選択図】図22
