摘　　要：传统特征提取方法在运动赛事中,对运动员技战术运用特征提取不准确,导致对运动员综合评估不全面,为此设计一种羽毛球多球练习技战术运用特征提取方法。通过描述聚类对象的数据种类,计算行为算子距离,识别羽毛球多球技战术中发生的多种行为,并划分算子识别的正确阈值,提供特征提取类别支撑。计算行为统计发生频次,降低帧数模糊过渡界限对技战术运用区域行为特征量化结果的影响,实现对技战术运用特征的提取。设计对比实验的方式,验证了提出方法可提高对运动员技战术运用的特征提取准确率,更加适用于对运动员行为的综合评估。The traditional feature extraction method is not accurate for the technical and tactical use of athletes in sports events,which leads to the incomplete comprehensive evaluation of athletes.Therefore,a feature extraction method for the technical and tactical use of badminton multi-ball practice is designed.By describing the data types of cluster objects,calculating the operator distance,identifying the various behaviors in badminton multi-ball tactics,and dividing the correct threshold of operator recognition,the classification support of feature extraction is provided.The frequency of behavior is calculated to reduce the influence of fuzzy transition boundary of frame number on the quantization result of the behavior characteristics of technical and tactical application area,and the characteristics of technical and tactical application are extracted.By designing the method of comparative experiment,it is verified that the proposed method can improve the accuracy of feature extraction in the use of athletes’skills and tactics,and is more suitable for the comprehensive evaluation of athletes’behavior.
