摘要
通过描述地球重力场、地磁场和实际测量传感器3轴之间的关系,阐述了空间三维角的测量原理,再结合加速度传感器和磁阻传感器的原理及其误差分析,给出了测量空间三维角的软硬件设计。
It describes the relation the three axes in the sensors and the gravity field and earth magnetic field to elaborate the principle of measuring 3D in space, introduces the principle of the accelerometer ADXL202 and that of the magnetic sensor HMC1022, analyzes the error of sensors, designs the hardware and software implement.
