足球运动员的加速度测量
您好，
我正在寻找具有加速度计工作原理和数据解释知识的专家，用于以下简要项目描述：
足球运动员在特制马甲中放置了加速度计，以确保他无法移动。
在足球比赛中，运动员以不同方向以及变化的速度奔跑，其中执行了许多加速。如何根据加速度计数据来测量所有通过的3米段的加速度数值？
问题：
- 如何平滑数据并赋予加速度实际值？
- 如何根据加速度计数据确定已完成的距离？
- 如何确定3米段加速度的起始和最终速度？
- 为什么个别数据大于20m/s²？
- 如何理解负值？
首要目标是比较不同训练和比赛之间的最高加速度。
有兴趣的人请联系，以确定合作原则。

Is the device-sensor-accelerometer already selected? The issue is interesting, although the "overarching goal" seems to be a means rather than an end. We compare for a purpose and not just for the sake of comparison... It would also be appropriate to measure - that is, determine the direction of acceleration - then there will be no negative values (unless deceleration is treated as negative acceleration).

We tested the Shimmer accelerometer, but its drawback was that the person with the phone had to stand next to it. Besides that, I was taking measurements with phone applications. It turns out that there are no easily available small devices that can be inserted into a vest, collect data, and read it after training. I am very open to proposals in this matter, including establishing cooperation with a person who will assemble such an accelerometer for research purposes, and if successful, for further commercial activities.
