排球抛球及挥臂击球动作数据的采集与传输研究

排球抛球及挥臂击球动作具有动态性,当前数据采集与传输方法适应能力较低,导致数据采集与传输精度、实时性和可靠性受到很大的影响,为此,提出一种新的排球抛球及挥臂击球动作数据的采集与传输方法,依据每个惯性传感器得到排球运动员进行抛球及挥臂击球动作时的关节姿态数据,经实时坐标转换处理完成人体模型中的所有关节对排球抛球及挥臂击球动作的对应跟踪,获取相应数据。采集到排球抛球及挥臂击球动作数据后,通过传感器网络,依据节点传输概率对排球抛球及挥臂击球动作数据进行传输。为了使节点间协作完成数据传输,通过构建预测连接时间的数据转发模型实现数据转发。实验结果表明,所提方法具有很高的采集精度、传输实时性和可靠性。

Volleyball ball and stroke movement of data acquisition and transmission

volleyball ball and stroke action dynamic, low ability to adapt the current data acquisition and transmission method, lead to data acquisition and transmission precision, real-time and reliability has great influence, therefore, put forward a new volleyball ball and stroke movement of data acquisition and transmission method, on the basis of each inertial sensor for volleyball players in volleyball and stroke gesture of joint profile data, the real-time coordinate conversion processing is completed all the joints in the human body model for volleyball the corresponding track ball and stroke, obtain corresponding data.Volleyball ball and stroke movement data collected, through the sensor network, based on the node transmission probability and throw the ball to the volleyball and stroke movement data transmission.In order to complete the data transmission between envoys point, by building connection time data forwarding forecast models for data forwarding.The experimental results show that the proposed method not only has the very high acquisition precision, real-time and reliability in transmission.
