基于三维图像的羽毛球运动合理性判断方法研究与仿真

针对当前彩色视频中羽毛球动作合理性判断成本高,且二维信息不充分,造成羽毛球运动合理性判断效果不佳的问题,提出一种新的基于三维图像的羽毛球运动合理性判断方法。在时间维度上建立深度运动模型;通过该模型描述羽毛球运动的每个动作,获取每个动作的三维图像。在三维空间中,选用空间金字塔方向梯度直方图对羽毛球运动特征进行提取。在此基础上对正确羽毛球运动和待判断羽毛球运动特征的相似度进行计算,将得到的相似度结果和既定阈值进行比较,从而实现羽毛球运动合理性判断。实验结果表明,所提方法具有很高的判断精度,且适应能力较强。

Badminton rationality judgment method based on 3 d image research and simulation

Rationality judgment for the current color video in the badminton movement cost is high, and the two-dimensional information not fully, the badminton rationality judgment of problem, put forward a new badminton rationality judgment method based on 3 d images.Depth motion model is established on the time dimension, through the model describe the badminton every movement, access to 3 d image of each skill.In three-dimensional space, use space pyramid gradient direction histogram to extract characteristics of badminton sport.On the basis of the characteristics of badminton sport badminton movement and to judge right of similarity calculation, will get the similarity of results and comparison for given threshold, so as to realize badminton rationality judgment.The experimental results show that the proposed method has high accuracy, and strong ability to adapt.
