如何从加速计计算正确的速度值

我需要计算空间的iPhone速度，例如打孔速度。 我的第一个问题是：是否加速度值accelerometer:didAccelerate与此筛选操作： gravity_x = acceleration.x * kFilteringFactor + gravity_x * (1.0 – kFilteringFactor); gravity_y = acceleration.y * kFilteringFactor + gravity_y * (1.0 – kFilteringFactor); gravity_z = acceleration.z * kFilteringFactor + gravity_z * (1.0 – kFilteringFactor); float gravityNorm = sqrt(gravity_x * gravity_x + gravity_y * gravity_y + gravity_z * gravity_z); accelX = acceleration.x – gravity_x / […]
