Abstract

In this paper, we consider magnetic positioning and tracking of objects and provide a comparison of the characteristics of two major measurement models: the magnetic dipole model and the mutual inductance model. The numerical results obtained by applying these models to a short-range position measurement application, with a maximum operating distance of approximately 50 cm, are compared. Based on the results of this comparison, a prototype 9-sensor array is developed, experimental tests are performed, and extensive measurement results are presented. Outcomes show the feasibility of tracking the position and orientation of a mobile coil in real time with a median positioning error below 1 cm and a worst-case error of about 2 cm and 11 degrees inside a spatial region of 30 × 30 × 30 cm³ operational volume.

摘要

在本文中，我们考虑物体的磁定位与跟踪，并对两种主要测量模型的特性进行比较：磁偶极子模型和互感模型。将这些模型应用于最大工作距离约为50厘米的短程位置测量应用中所获得的数值结果进行了比较。基于该比较结果，开发了一个9传感器阵列原型，进行了实验测试，并给出了大量测量结果。结果表明，在30×30×30立方厘米的操作空间区域内，实时跟踪移动线圈的位置和方向是可行的，其中位定位误差低于1厘米，最坏情况下的误差约为2厘米和11度。
