舰艇磁性检测中矢量磁传感器的姿态校正
|
摘要
舰艇磁性检测中矢量磁传感器的姿态倾斜将导致测量不准确,为此提出了一种矢量磁传感器的姿态校正方法;通过在倾斜磁传感器位置紧密放置一标准磁传感器,以标准测量值为依据采用APO算法反推得出倾斜传感器的姿态角矩阵,根据此矩阵对倾斜传感器测量值进行修正可得到较准确的舰艇磁场测量值;通过仿真和船模实验对该方法进行了验证,实验表明测量精度有了较大改善;该方法可用于工程实际,为提高舰艇磁性检测的精度提供了有益思路。
Incorrect measurement would occur when vector magnetometer is slanting in ship's magnetic measuring,thus a method is proposed to correct attitude of magnetometer.A standard magnetometer is placed closed with the declining magnetometer,and APO arithmetic is used to calculate matrix of attitude angle taking standard measured value as criterion,then accurate value of ship's magnetic field can be got by revising measured value of slanting magnetometer based on the matrix.The method is verified by simulation and ship model's experiment,and the result indicated that the measured precision is improved greatly.The method can be applied to engineering and supports a path for improving the precision of ship's magnetic measurement.
