摘要
艺术体操评分规则要求动作具有多样性,但目前缺乏量化指标来评估动作的空间利用多样性。文章提出了基于空间分布熵的艺术体操个人棒器械难度空间利用评估方法,通过构造运动员器械难度动作空间分布的时间序列,计算器械难度动作三维空间分布熵,并根据空间分布熵的大小来评估器械难度动作空间利用的多样性。文章用第35届世界艺术体操锦标赛个人棒单项决赛的相关数据作为测试用例,来验证文章所提出方法的有效性。计算结果显示,器械难度得分高的运动员空间分布熵更大,说明其器械难度动作完成的数量种类多,动作容量大,空间运用更具多样化。测试结果表明,文章所提出的基于空间分布熵的器械难度空间利用评估方法可以有效地表征运动员完成器械难度动作的空间多样性。
The rhythmic gymnastics scoring rules require the space utilization diversity,but it lacks a quantitative indicator to space diversity of apparatus difficulty.In this paper,we propose a rhythmic gymnastics space utilization evaluation approach based on spatial distribution entropy.The time series of space distribution of apparatus difficulty action is formulated,and we use the time series to calculate the 3D spatial distribution entropy of apparatus difficulty action.The spatial distribution entropy is used to reflect the space diversity of apparatus difficulty of clubs events.The data of the 35th Rhythmic Gymnastics World Championships individual finals is used as the testing set.According to the results,we find that the top athletes have the larger entropy,which means the spatial states of their actions are more complicated,variable and uniform.The test results also show that the spatial distribution entropy is an effective quantitative indicator for space diversity evaluation of apparatus difficulty.
