如何从 Android 3 轴加速度计的加速度计读数中删除重力因子 [英] How to remove Gravity factor from Accelerometer readings in Android 3-axis accelerometer

问题描述

谁能帮忙从加速度计读数中去除 g 因子?

Can anyone help on removing the g factor from accelerometer readings?

我使用 SensorEventListener 和 onSensorChanged() 方法来获取 Sensor.TYPE_ACCELEROMETER 数据.我只需要所有方向上的纯加速度值.所以在任何状态下，如果设备稳定(或匀速)，它应该大致给出 (0.0,0.0,0.0).

I am using SensorEventListener with onSensorChanged() method for getting Sensor.TYPE_ACCELEROMETER data. I need only pure acceleration values in all directions. So at any state if the device is stable (or in constant speed), it should give (0.0,0.0,0.0) roughly.

目前，根据它的俯仰和滚转，它根据作用在每个轴上的 g 力为我提供可变的输出.

Currently, depending on its pitch and roll, it gives me variable output depending on the g forces acting on each axis.

我希望有一些公式可以消除这一点，因为我还从 Sensor.TYPE_ORIENTATION 侦听器中获得了方向值(俯仰和滚转).我用过一些，但没有用.

I hope there is some formula to remove this, as I also get orientation values (pitch and roll) from Sensor.TYPE_ORIENTATION listener. I have used some but it didn't work.

推荐答案

使用 Sensor.TYPE_LINEAR_ACCELERATION 而不是 Sensor.TYPE_ACCELEROMETER

Use Sensor.TYPE_LINEAR_ACCELERATION instead of Sensor.TYPE_ACCELEROMETER
