Abstract
Systems and methods are provided for generating a high density (HD) map for identifying a location and/or an orientation of an electromagnetic (EM) sensor within an EM volume in which an EM field is generated by way of an antenna assembly. A measured EM field strength at each gridpoint of a set of gridpoints of the EM volume are received from a measurement device. An EM field strength at each gridpoint of a second set of gridpoints of the EM volume is calculated based on a geometric configuration of an antenna of the antenna assembly. The HD map is generated based on the measured EM field strength at each gridpoint of the first set of gridpoints and the calculated EM field strength at each gridpoint of the second set of gridpoints.
