摘　　要：提出了一种获得磁跟踪系统参数的简单方法,给出了利用磁传感器和三轴正交线圈作为磁场检测器件时的算法公式。该方法通过测量磁场中与发射线圈轴垂直的平面上三个点得磁场信号获得对应该发射线圈的各系统参数。试验结果表明利用该方法获得的参数相对利用传统方法获得的参数提高了系统定位精度。A simple method to get the system parameters of the magnetic tracking device was proposed. The formulas under the condition which coils or magnetic sensors are used to detect the magnetic field were also provided. The method obtains the system parameters corresponding to the sending coil by measuring the magnetic field on three different points. The plane of the points is perpendicular to the axis of the sending coil. The experimental results indicate the parameters provided by this method improve the system accuracy compared with the parameter provided by traditional method.
