【摘要】：本文利用三维球体轨迹重建系统分析的高效性、易操作性、方便性的特点,在单个摄像机的固定标记下,为现场分析乒乓球球体飞行速度与落点及技战术运用提供新的支持。选取2014年国际乒联世界巡回赛成都公开赛中的26场比赛(12场男子单打比赛、14场女子单打比赛)作为实验对象,运用比赛中运动员回合终拍的球体飞行速度与落点作为研究对象,为了更好、更快的完善赛场上技战术分配与实施而进行球体飞行速度与落点统计分析研究。本文采用文献资料法、录像分析法、数理统计法等方法对男、女运动员的球体飞行速度特征、相同球体落点与终拍技术的球体飞行速度特征、男女运动员近网区、中区、底线区的终拍球体飞行速度比较以及球体飞行速度对相同球体落点与男、女失分运动员站位的受迫性失误差异性比较进行分析研究。通过分析探究,本文得出的研究结论如下:1.通过利用单个摄像机在比赛场内标记下,运用三维球体轨迹重建系统能够较为准确的测试出场上运动员在回合中每一板球的球体飞行的水平速度,可以很好为临场的教练员与运动员在赛场上迅速地反馈提供必要的技战术应对措施。2.男、女运动员在乒乓球比赛中的球体飞行速度特点均以低速球(小于7米/秒)与中速球(小于15米/秒)为主,而大于15米/秒的高速球占极少数,呈现出运动员在激烈的比赛中不会让对手拥有太多的扣杀以及挑打的机会来提高球速而获得回合胜利。3.不同的球体落点区域以及终拍技术,其球体飞行速度与落点会发挥出不一样的得分效果。4.近网区多为发球、摆短技术实行的有效区域,运动员必须控制球体速度、落点以及身体动作才能使该回合进攻更具威胁性。而中区多以拉攻、挑打、扣杀等强进攻性的技术为主,得分的第一要素是球体飞行速度较快,使运动员处于被动回接球状态。另外,底线区的特点是落点刁钻、球体飞行弧线长和低,运动员可以最大幅度的提高击球力量,球速过快造成对手措手不及。5.在1-反手位因为男子运动员在比赛中多以凶狠搏杀、力求主动占据上风,在寻求不同的落点压制对方并且加上较快的球体飞行速度而迫使对方造成不必要的失误。2-中路由于男子运动员力量素质方面都优于女运动员和在比赛中球路以及速度等变化较多与女子运动员平缓的保持于相持状态的差别有关。6.由于球体落点的调动以及球体飞行速度较快,失分运动员站位为1-反手位时,女子运动员的球体平均速度较快的原因是双方相持板数较多,且以近台左右调动转换为主要,球体飞行距离短、弧线低及速度快。
[Abstract]:Based on the characteristics of high efficiency, easy operation and convenient analysis of 3D ball trajectory reconstruction system, this paper provides a new support for analyzing the flying speed and landing point of table tennis ball and the application of technique and tactics under the fixed mark of a single camera. In this paper, 26 events (12 men's singles and 14 women's singles) in the 2014 Chengdu Open World Table Tennis Tour are selected as the experimental objects, and the flying speed and landing point of the players' final shot in the round are used as the research objects. In order to improve the distribution and implementation of techniques and tactics on the field, the statistical analysis of ball flying speed and landing point was carried out. In this paper, the characteristics of ball flying speed of male and female athletes, the characteristics of ball flying speed of the same ball landing point and final shooting technique, the near net area and the middle area of male and female athletes are analyzed by the methods of literature, video analysis, mathematical statistics and so on. The comparison of final shot ball flying velocity and ball flying velocity in the bottom line area and the comparison of forced error difference between male and female athletes with the same ball landing point were carried out. By analyzing and exploring, the conclusion of this paper is as follows: 1. By using a single camera marked in the field and using a three-dimensional ball track reconstruction system, the horizontal speed of the players' ball flying in each turn of the game can be measured more accurately. It can provide necessary technical and tactical measures for coaches and athletes on the field to feedback quickly. 2. The characteristics of ball flying speed of male and female players in table tennis are mainly low speed ball (less than 7 m / s) and medium speed ball (less than 15 m / s), while high speed ball more than 15 m / s is rare. It shows that players don't give their opponents too many knockoffs and pick-up opportunities to improve the speed of the game and win the round. 3. With different sphere impact areas and final shot techniques, the ball flying speed and landing point will play a different scoring effect. 4. In order to make the round attack more threatening, the player must control the ball speed, the landing point and the body action in order to make the round attack more threatening. In the central area, the most important technique is to attack, pick, smash and so on. The first factor of scoring is the fast flying speed of the ball, which makes the player in the state of passive return and catch the ball. In addition, the bottom line is characterized by the point of difficulty, ball flying arc long and low, the player can maximize the strength of the ball, too fast ball caused the opponent caught off guard. 5. In the 1- backhand position because male athletes fight more ferociously in the competition and try to gain the upper hand on their own initiative, In seeking different landing points to suppress each other and add faster ball flying speed to force the other side to make unnecessary mistakes. 2- because the strength quality of male athletes is superior to that of female athletes and in the course of the game; and The change of speed and so on is related to the difference of the female athletes to maintain the holding state. 6. 6. Because of the movement of the ball falling point and the fast flying speed of the ball, the average speed of the female athlete's sphere is faster when the position is 1- backhand position, the reason is that the number of the two sides holding plates is more, and the movement from the near platform to the left and right is converted to the main one. The sphere has short flying distance, low arc and high speed.
