摘要: This disclosure relates to localization and tracking of an object. As one example, measurement data can be stored in memory to represent measured electrical signals at each of a plurality of known measurement locations in a given coordinate system in response to an applied signal at an unknown location in the given coordinate system. A dipole model cost function has parameters representing a dipole location and moment corresponding to the applied signal. A boundary condition can be imposed on the dipole model cost function. The unknown location in the given coordinate system, corresponding to the dipole location, can then be determined based on the stored measurement data and the dipole model cost function with the boundary condition imposed thereon.

摘要翻译: 本公开涉及对象的定位和跟踪。 作为一个示例,响应于给定坐标系中未知位置处的施加信号,测量数据可以存储在存储器中以在给定坐标系中的多个已知测量位置的每一个处表示测量的电信号。 偶极子模型成本函数具有表示与施加的信号相对应的偶极位置和力矩的参数。 可以对偶极子模型成本函数施加边界条件。 然后,可以基于存储的测量数据和施加有边界条件的偶极子模型成本函数来确定给定坐标系中对应于偶极位置的未知位置。
