技術說明

本發明之影像追蹤方法包含以下步驟：(A)以影像擷取裝置持續取得多個原始影像，其包含第一視格及第二視格。(B)傳送原始影像至運算裝置，運算裝置根據預設影像集辨識原始影像，以產生位置框。(C)自位置框中取得包含目標物的初始前景影像，初始前景影像和位置框具有像素比值，根據像素比值與第一閾值決定已辨識前景影像。(D)自已辨識前景影像取得一特徵，根據第一視格的已辨識前景影像的特徵與第二視格的已辨識前景影像的特徵取得第一特徵分數。(E)根據第一特徵分數與第二閾值產生目標物匹配結果，且根據目標物匹配結果記錄目標物的移動軌跡。 An image tracking method includes the following steps: (A) obtaining a plurality of original images including a first frame and a second frame by an image capturing device; (B) transmitting the plurality of original images to a computing device; the computing device identifying the plurality of original images to generate a position box according to a preset image set; (C) obtaining an initial-foreground image from the position box including the object; a pixel ratio being defined based on the initial-foreground image and the position box; an identified-foreground image being determined according to the pixel ratio and a first threshold value; (D) obtaining a feature from the identified-foreground image; obtaining a first-feature score according to the feature of the identified-foreground image of the first frame and that of the second frame; (E) generating an object-matching result according to the first-feature score and a second threshold value; recording a trajectory of the object according to the object-matching result.
