问题描述

我在涉及陀螺仪的一个项目工作...

I'm working in a project that involves gyroscopes...

我使用的Arduino和ITG 3200读取来自陀螺仪的数据。我得到了度/秒3值为每个轴(X,Y,Z)。

I'm using Arduino and an ITG 3200 to read the data from the gyroscope. I get 3 values in deg/s for each axis (x,y,z).

我的问题是:我怎么能知道设备的实际(物理)位置或方向(比方说,飞机)。必须有一个数学公式或类似的东西。

My question is: How can I know the actual (physical) position or direction of the device (let's say an airplane). There has to be a math formula or something like that.

推荐答案

仅使用陀螺仪信号(你必须数值积分),最终你还是会遇到麻烦,由于漂移。什么通常所做的是组合的加速度计(用于低频信号,即漂移)配有一个陀螺仪(高频信号)。这里显示更多或更少的链接几个环节正是你想要的:

Using only the gyroscope signal (which you have to integrate numerically), you'll eventually run into trouble, due to drift. What's normally done is combining an accelerometer (for low frequency signals, i.e. drift) with a gyroscope (for high frequency signals). Here's a link few links showing more or less exactly what you want:
