摘    要:为解决内窥镜在人体内部的定位,以及永磁体建模解析式过于复杂不利于快速计算的问题,提出了一种基于三点定位原理的定位方法,并利用数据拟合法对永磁场数据进行拟合,得到简化的永磁场解析表达式反求位置坐标的方法。并对简化的结果和直接建模仿真结果进行比较,发现该定位方法及简化确实可行。

关 键 词:无线内窥镜  永磁场  三点定位  数据拟合

Abstract:In order to solve the orientation endoscope in the body and the problem which is too complex and not easy to calculate quickly in permanent magnets modeling, a locating method was advanced based on the principle of three points location theory. Then the data of permanent magnetic was fitted to using the data fitting algorithms method, and a method of reverse spatial position was got by simplified permanent magnetic formula. By comparing the results of simplified calculation with direct modeling methods, this method is really useful and feasible.
Keywords:wireless endoscopes  permanent magnets  three points location theory  data fitting
