加速度传感器中有一种是三轴加速度传感器,同样的它是基于加速度的基本原理去实现工作的,加速度是个空间矢量,一方面,要准确了解物体的运动状态,必须测得其三个坐标轴上的分量;另一方面,在预先不知道物体运动方向的场合下,只有应用三轴加速度传感器来检测加速度信号。由于三轴加速度传感器也是基于重力原理的,因此用三轴加速度传感器可以实现双轴正负90度或双轴0-360度的倾角,通过校正后期精度要高于双轴加速度传感器大于测量角度为60度的情况。三轴加速度传感器的好处就是在预先不知道物体运动方向的场合下,只有应用三维加速度传感器来检测加速度信号。三维加速度传感器具有体积小和重量轻特点,可以测量空间加速度,能够全面准确反映物体的运动性质。
