摘要
健身跑是体育运动中最常用的锻炼方式,不恰当的跑步方式,不仅达不到理想的健身效果,而且很容易对身体特别是膝盖造成伤害。针对目前跑步系统缺乏科学指导和全程监测,本文提出了一个基于Kinect的虚拟健身跑锻炼系统。在动作识别方面,通过角度特征和关节点相对位置对Kinect采集的跑步动作信息进行降维,并分割出跑步动作元,利用动作元的曲线特征和分类模型匹配,进行跑步动作识别,同时对跑步姿态进行科学指导。在运动建模方面,分析用户心率和跑步强度的关系,构建用户的健身跑运动模型,并建立个性化科学跑步运动方案,使心率始终处在安全有效的心率区间内。实验结果表明,该系统具有较强的实用性和可行性,能够为用户进行安全、有效地健身跑锻炼提供科学的技术支持。
Fitness running is a common exercise in sports.Due to the improper running form,it is not only hard to reach the ideal fitness result,but also easy to harm the body seriously,especially the knee.To address the problems of lacking scientific guidance and monitoring in current running systems,this paper proposed a virtual running exercise system based on Kinect.In the action recognition,the dimension of running data collected from Kinect is reduced according to the angle characteristics and the relative position of human joints,and running action units are divided from motion features set.Then all kinds of running actions are recognized by matching with curve characteristics of action units and classification models.In addition,scientific guidance about their running poses is given to users while exercise.In the motion modeling,we analyze the relationship between the heart rate and running intensity,and build the fitness running model and the individualized scientific running exercise scheme,making the heart rate always in the safe and effective range.The experiment results show that our system is practical and feasible to provide a scientific method for safe and effective fitness running to users.
