本論文では，移動軌跡の解釈を目的として，移動ベクトルの変換結果を投影することで，対象の移動を単純なパターンに表現できる追跡空間を提案した．それによると，対象の移動の部分軌跡が，単調で特徴的な挙動に置き換えられることによって，直進や進路変更を一義的に判定することができる．また，その挙動から得られる軌跡識別データにより，進行方向だけでなく，進路変更の鋭さや滑らかさの程度，更に，進路変更の向き（時計回り，反時計回り）を容易に検出できる・そして，その結果から，簡単な幾何学的移動軌跡（四角形やS字カープなど）も容易に検出できる．%Moving object tracking and analysis of locus are useful for measurement of human (analysis of flow of shopper, rehabilitation aid), fluid analysis, weather forecast and so on. The authors propose a tracking data which shows a locus of moving object by a characteristic and simple pattern. The tracking data is made by a transformation of a moving vector of the object. The data show a monotonous behavior at a local coordinate in the tracking space, when the object moves geometrically in real space. Using this model, it is possible to estimate a type of a partial locus of movement deterministically in real space. According to this method, it is easy to interpret the locus continuously and it is possible to reappear the movement of the object using the interpretation result. In this paper, the method is explained and a result of an experiment using the images of human movement is shown.
