如何通过加速度计处理距离? [英] How can i handle distance through accelerometer?

问题描述

我的对象从零开始.时间到了..它涵盖了一定距离，那么我该如何测量呢?

My object starts from zero. When the time goes..It covers some distance, so how can I measure this?

推荐答案

哦，很简单.您所需要做的就是实现惯性测量单元，然后实现卡尔曼滤波器，通常是使用环形激光陀螺仪或光纤陀螺仪完成的，它们是固态"设备，可以通过测量相对论效应来工作，并且其售价要比iPhone中的硅微机械传感器高得多，但您可能会使其正常工作.

Oh, it's simple. All you have to do is implement an Inertial Measurement Unit and then an Inertial Navigation System. It's going to be hard to do without rotation sensors, it would probably require a Kalman Filter for accuracy, and typically it is done with ring laser gyros or fiber optic gyros, which are "solid state" devices that work by measuring relativistic effects and sell for rather higher prices than the silicon micromachined sensors in the iPhone, but you might get it to work.

或者，您可以只使用GPS.

Or, you could just use the GPS.
