鷹眼即時回放系統在羽球比賽現況之探討

Abstract

鷹眼系統引入羽球比賽現場，對於判決是一項具有重大意義與革新，不僅對選手有益，有助於比賽的公正性，提升裁判水平，確保比賽的公平與準確性，對球迷的觀賞球賽服務品質也有提升。2014年羽球超級系列比賽正式啟用鷹眼系統，使用至今還是有很多問題與重播回放死角，鷹眼雖然極度敏銳，還只是電腦模擬計算的結果。羽球幾乎無法使用鷹眼的模擬計算系統來確定最後的結果，因為光是要模擬計算羽球的飛行，就要比網球、板球及足球的模擬運算複雜幾十倍。羽球不像上述幾種球類都是個完整渾圓的球體，羽球不但是圓錐狀，而且會以不斷旋轉的方式進行快速飛行，再加上每根羽毛的根部間又有些微差異的空隙，以及羽毛在比賽中也會逐漸破損，這些因素都導致了「電腦模擬」來判斷羽球落點位置的困難性極高。因此，建議世界羽球聯合會必須積極地改進目前的電腦模擬程式，進行整體運算羽球在這個空間的移動位置。並建立起一個模擬立體空間系統，使鷹眼現場即時回放系統更符合羽球這項運動。

The introduction of the hawk eyes system into badminton games represents a revolutionary meaning for the judgement of the referees. It would not only benefit to the players, the referees, ensure the fairness and the accuracy of the games, but also promoted the quality of serviceability in watching the games. The hawk eye in-time replay system has been officially adopted by the badminton super series since 2014. Up to date there indeed exist some problems such as dead angles while replaying. This system may be extremely sharp, but depends mainly upon the results from computer simulation. The badminton birds are not spherical but cone shape. The rotation during flying as well as the damage and the gaps in the feather would cause difficulties in simulating calculation. It is much more complicated than the simulation of a tennis, cricket, or soccer ball. The present study thus suggested that it may be necessary for BWF to pay more attention in improving the computer simulation program to make a complete calculation and establish a spatial simulation system for the movement of the badminton birds. So that the hawk eye in-time replay system may be more suitable for using in the badminton games.
