Zusammenfassung:To provide an object tracking method capable of reducing a calculation load of object tracking.SOLUTION: An object tracking method has a step of classifying an object whose elapsed time from a time when the object is detected in a moving image where a plurality of frames is lined up along a time sequence continue for a prescribed time as a dynamic body, a step of classifying an object whose elapsed time is below the prescribed time as a candidate of a dynamic body, a step of checking a correspondence of an unrecognized object detected in a current frame to the dynamic body (S1 to S6), a step of mapping the unrecognized object as the dynamic body when it is judged that the unrecognized object corresponds to the dynamic body (S7:YES, S30), a step of checking a correspondence of the unrecognized object to the candidate of a dynamic body when it is judged that the unrecognized object does not correspond to the dynamic body (S7:NO, S8 to S10), and a step of mapping the unrecognized object with the candidate of a dynamic body when it is judged that the unrecognized object corresponds to the candidate of a dynamic body (S10:YES, S31).SELECTED DRAWING: Figure 4 【課題】物体追跡の計算負荷を軽減できる物体追跡方法を提供する。【解決手段】時系列に沿って複数のフレームが並んでいる動画の中で検出された物体の検出されてからの経過時間が、所定時間以上継続している物体を動体と分類し、所定時間未満の物体を動体候補と分類しておき、現在フレームで検出した未認識物体と動体との対応を調べる段階(S1〜S6)と、未認識物体と動体とが対応していると判断された場合は未認識物体と動体とを対応付けする段階(S7:YES、S30)と、未認識物体と動体が対応していないと判断された場合は、未認識物体と動体候補との対応を調べる段階(S7:NO、S8〜S10)と、未認識物体と動体候補とが対応していると判断された場合は未認識物体と動体候補とを対応付けする段階(S10:YES、S31)と、を有する物体追跡方法。【選択図】図4
