| 摘 要： | 为了实现在强磁干扰环境下准确且智能地测定航向角,从影响磁传感器测定航向角精度的诸多因素分析,采用经典的基于椭圆拟合的校正算法,设计了一种由6只磁传感器围成一个圆的多磁传感器的自动磁校正设备。提出了一种有效的误差补偿技术和准确、智能的测定航向角的方法,避免了手动旋转单只磁传感器来采集不同方向的磁场的操作。多次实验结果表明:在室内强干扰环境中,这种校正技术补偿后的航向误差从150°降低到2.5°。

| Abstract: | In order to measure heading angle accurately and intelligently in strong magnetic perturbed environment,analyze numerous factors which influence heading angle measurement precision of magnetic sensor,and present use classic calibration algorithm based on ellipse fitting,and design a multiple magnetic sensor auto calibration device,which composed of six magnetic sensors form a circle.Present an effective error compensation technology and accurate and intelligent method for heading anglemeasurement,which avoids manual operation rotating of a single magnetic sensor to collect magnetic field in different directions.The intelligent heading measuring system is tested repeatedly and verified in strong magnetic perturbed environment,this calibration technology reduces the original heading error from 150° to 2.5°. |
