| Abstract(in English) | In recent years, sports video analysis has been more and more important. Especially, player tracking on broadcasted soccer videos is actively researched. It consists of two phases: a player detection, and a field detection for a perspective transformation. The conventional method uses computationally expensive AIs or algorithms for every phases. To reduce the processing time, this paper proposes a method which perform the above two phases with a single AI. This method detects players and field keypoints with YOLOv4 simultaneously. Then the perspective transformation matrix is soon calculated. Experimental results have shown that the processing time per frame for the proposed method was 0.119 [s] while that of the conventional method was 0.205 [s]. |
