To predict a track of a moving object based on information of a plurality of tracks in the past.SOLUTION: A track prediction device 1 comprises: a center-of-gravity track calculation unit 2 that calculates a center-of-gravity coordinate points of measurement points for constituting a past track of interest and measurement points for constituting other past tracks being present within a predetermined range from the measurement point with respect to each of the measurement points constituting the past track of interest, and calculates a center-of-gravity track, which is the track represented by the plurality of calculated center-of-gravity coordinate points; a reliability calculation unit 3 that calculates a reliability of each of the center-of-gravity tracks calculated by setting each of the plurality of past tracks as a past track of interest; a center-of-gravity track selection unit 4 that selects one of the center-of-gravity tracks based on the reliability of the center-of-gravity tracks; and a track prediction unit 5 that calculates a track which gradually converges to a selected center-of-gravity track from the observed coordinates of the moving body as a predicted track of the moving body.SELECTED DRAWING: Figure 8
【課題】過去の複数の航跡の情報に基づいて、移動体の航跡を予測する。【解決手段】航跡予測装置1は、注目する過去航跡を構成する測定点と、当該測定点から所定の範囲以内に存在する他の過去航跡を構成する測定点との重心座標点を、前記注目する過去航跡を構成する測定点のそれぞれに対して算出し、算出した複数の前記重心座標点により表される航跡である重心航跡を算出する重心航跡算出部2と、複数の過去航跡のそれぞれを前記注目する過去航跡とすることにより算出された前記重心航跡のそれぞれについて、信頼度を算出する信頼度算出部3と、前記重心航跡のうち前記信頼度に基づいて一つの前記重心航跡を選択する重心航跡選択部4と、移動体の予測される航跡として、前記移動体の観測された座標から、選択された前記重心航跡に徐々に収束する航跡を算出する航跡予測部5とを有する。【選択図】図8
