概括

超宽带 (UWB) 追踪系统在稳定的网球运动中显示出良好的可靠性,但在高速,敏捷的练习中存在重大错误. 由于快速加速和方向变化,准确性降低了.

科学领域:

运动科学运动科学运动科学
生物力学生物力学
绩效分析绩效分析

背景情况:

运动员跟踪系统对于运动员表现分析至关重要.
与GNSS和光学系统相比,超宽带 (UWB) 系统在球拍运动中的准确性和成本方面具有潜在的优势.

研究的目的:

为了评估特定UWB跟踪系统 (GenGee Insait KS) 对于网球特定运动的准确性.
为了比较UWB系统的性能与黄金标准的光学运动捕捉系统 (VICON).

主要方法:

十名业余网球运动员进行了七种不同的练习 (热身,敏捷性,战术) 带有或没有球拍.
经过的距离是从UWB和VICON系统收集的原始数据计算出来的.
统计分析包括根平均平方误差 (RMSE),标准化平均差异和类内相关系数 (ICC).

主要成果:

在距离测量方面,UWB系统表现出良好的可靠性 (ICC = 0.91).
平均RMSE为0.65米 (X轴) 和0.76米 (Y轴).
在高速,敏捷的运动 (例如,蜘蛛跑) 中发现了显著的差异,较大的错误和过高估计归因于手臂/部运动.

结论:

在网球中,UWB系统对稳定状态运动具有可接受的准确性.
在使用高强度,网球特有的动作时,由于明显的不准确性,建议谨慎使用手臂安装的UWB设备.
可能需要进一步的研究来完善UWB技术用于动态球拍运动分析.

Vector Functions and Motion: Problem Solving

Accurate position tracking is fundamental to the safe and effective operation of unmanned aerial vehicles (UAVs), particularly during precision maneuvers near complex structures. In this scenario, a drone is programmed to perform a high-precision inspection of a vertical structure, starting at position ((x, y, z) = (3, 0, 0)), with an initial velocity oriented in the positive z-direction. The trajectory of the drone is governed by a time-dependent acceleration function a(t), which is predefined...
