摘要
研究了一种采用加速度计、磁阻传感器和单片机的三自由度定位装置及其算法 ,给出了A/D转换器的位数与系统分辨率的关系 ,研究了环境磁场对测量结果的影响 ,提出了环境磁场补偿算法并讨论了补偿算法的误差。该装置可用于运动物体航向、俯仰和倾斜三个方向的姿态角的测量。
A 3 DOF (Degree of Freedom) tracking system which is composed of accelerometers, magnetoresistive sensors and MCU and its algorithm are described. The relationship between the number of bits of A/D converter and the resolution of the system is discussed. The calibration algorithm to compensate the influence of the environmental magnetic field is presented. The error of the calibration algorithm is also analyzed. The proposed system can be used to measure the accurate values of heading, pitch and roll.
