【摘要】 目的提出一种不依赖磁场分布模型且采用简单几何方法求解的双磁棒旋转搜索定位/跟踪方法。方法设计基于数字信号处理器(digital signal processor,DSP)的双磁棒旋转搜索定位/跟踪系统,对双磁棒旋转搜索定位/跟踪方法的可行性进行初步验证。结果平均位置误差为0.954,平均姿态误差4.86°。结论双磁棒旋转搜索定位/跟踪系统有很好的稳定性,搜索速度和定位精度还需进一步提高。更多还原

【Abstract】 Objective To propose a new electromagnetic tracking method based on two rotating coils,which does not depend on the magnetic model and uses geometry algorithm. Methods An electromagnetic tracking system was developed based on digital signal processor( DSP) and the feasibility of which was verified with experimental results. Results Average error of position was 0. 954° and average error of orientation was 4. 86°.Conclusion The new magnetic tracking system is stable and works well while the speed and accuracy of the system need to be further improved.更多还原
