【摘要】 本研究介绍了一种应用于消化道微磁囊磁定位中的补偿地磁场干扰的方法。该方法通过设置补偿值来标记地磁场的干扰水平,并且用测量值减去补偿值来达到补偿干扰的目的。通过实验表明,该方法可以准确地确定定位背心所处的地磁场干扰水平;三维跟踪轨迹表明,该方法很大程度提高了微磁囊在消化道中定位的准确度。更多还原

【Abstract】 A method for the suppression of geomagnetic field interference is here-in introduced.It is designed for use in the magnet locating system of the engineering-based microcapsule inside the alimentary tract.This method marks the geomagnetic field interference levels by getting the static value.Then subtracting the static value from the dynamic value.The results of the experiment show that the method can assess the geomagnetic field interference levels around the locating waistcoat accurately.And the three-dimensional tracking trajectory shows that the method has greatly improved the accuracy of the capsule location inside the alimentary tract.更多还原
