摘要
为了准确判断羽毛球运动员的运动动作,解决因角度问题产生的动作判断偏差,结合三维特征提取技术,提出羽毛球运动员动作判断方法。以传统的动作数据库为基础设定羽毛球运动员的动作判断标准,利用高清摄像机分别从不同的角度采集三维运动图像,在搭建的三维人体运动模型下,通过运动员的动作划分和三维特征参数设置两个步骤,实现对图像的特征提取。将提取的特征信息与设定的判断标准做匹配处理,从而得出羽毛球运动员实时动作的判断结果。为验证设计的羽毛球运动员动作判断方法的相关性能,设计对比实验,实验结果表明设计的羽毛球运动员动作判断方法,在保证判断执行时间的同时精度提高了4%。
In order to accurately judge the movements of badminton players and solve the deviation of the movement judgment caused by the Angle problem,a method for judging the movements of badminton players is proposed based on the three-dimensional feature extraction technology.On the basis of the traditional motion database set up badminton players action criterion,respectively using high-definition cameras acquisition three-dimensional motion images from different angles,under the three-dimensional human body motion model of scaffolding,divided by the movements of the athletes and three-dimensional characteristic parameters set two steps,implementation of image feature extraction.By matching the extracted feature information with the set judgment criteria,the real-time action judgment results of badminton players can be obtained.In order to verify the relevant performance of the designed badminton player action judgment method,a comparison experiment was designed.The experimental results showed that the designed badminton player action judgment method improved the accuracy by 4%while guaranteeing the execution time of the judgment.
