如何使用加速度计来测量距离为Android应用开发 [英] How to use Accelerometer to measure distance for Android Application Development

问题描述

我在应用程序开发行业只是一个初学者。我知道加速度计可用于沿三个轴返回当前加速度在每平方秒（米/秒2）米。但我已经知道，一个加速度计，也可以用速度计。

I am just a beginner in the application development industry. I know the accelerometer can be used to return the current acceleration along three axis in meters per second squared (m/s2). But I have come to know that an accelerometer can also be use as speedometer.

我想知道我可以利用加速度传感器来确定距离的兴趣点之间通过Android设备行进。如果可能的话，那我怎么才能实现呢？我已经看到了类似的问题：我怎么衡量一个iPhone使用加速度行进的距离<一href="http://stackoverflow.com/questions/3707726/how-do-i-measure-the-distance-traveled-by-an-iphone-using-the-accelerometer">How做我衡量使用加速度计，一个iPhone移动的距离？。但我并没有到了一个地步。

I want to know how I can use accelerometer to determine distance traveled by Android device between points of interest. If it is possible, then how can I implement it? I have seen a similar question "how do I measure the distance traveled by an Iphone using accelerometer" How do I measure the distance traveled by an iPhone using the accelerometer?. But I didn't come to a point.

推荐答案

您获得位置通过集成的线性加速两次，但错误是可怕的。这是在实践中无用的。

You get position by integrating the linear acceleration twice but the error is horrible. It is useless in practice.
