PROBLEM TO BE SOLVED: To improve determination accuracy of a false image.SOLUTION: A tracking device comprises: a first target tracking unit which corrects first information containing at least one of relative speed and distance of one or more targets present in a predetermined space detected by an image sensor according to a predetermined motion model and determines a first distribution relating to the first information; a second target tracking unit which corrects second information containing at least one of relative speed and distance of one or more targets present in the predetermined space detected by an active type sensor using reflection waves for measurement according to the predetermined motion model and determines a second distribution relating to the second information; a matching unit which performs matching of combination of distribution parameters obtained from the first distribution and the second distribution on the basis of correlation between the first distribution and the second distribution; and a false image determination unit which determines whether the second information is a false image on the basis of the combination of the distribution parameters.SELECTED DRAWING: Figure 1

    【課題】偽像の判定精度を向上させる。【解決手段】画像センサによって検出された所定の空間に存在する1以上の物標の少なくとも相対速度および距離のいずれか一方を含む第1の情報を所定の運動モデルに従って補正し、前記第1の情報に関する第1の分布を決定する第1の物標追尾部と、反射波で測定するアクティブ型センサによって検出された前記所定の空間に存在する1以上の物標の少なくとも相対速度および距離のいずれか一方を含む第2の情報を所定の運動モデルに従って補正し、前記第2の情報に関する第2の分布を決定する第2の物標追尾部と、前記第1の分布と前記第2の分布との相関に基づいて、前記第1の分布と前記第2の分布とから得られる分布パラメータの組み合わせをマッチングするマッチング部と、前記分布パラメータの組み合わせに基づいて、前記第2の情報が偽像であるか否かを判定する偽像判定部と、を備える、追尾装置が提供される。【選択図】図1
