3D Localization Field Correction via Electrode Calibration

The patent transforms the localization field characteristic measurements into corrected position information by changing the parameter representation through calibration. The system measures field characteristics (voltage) and transforms them into accurate position data using calibration data that accounts for field inhomogeneities, thereby resolving the contradiction between enabling position measurement and maintaining measurement accuracy.

The patent implements a feedback mechanism where the localization system continuously measures position using the localization field characteristics and compares these measurements against calibration data. The system uses the difference between measured and expected values to correct for inhomogeneities, creating a closed-loop feedback system that maintains measurement accuracy despite field variations.

The patent applies preliminary action by performing calibration measurements at multiple predetermined locations before actual position measurements are taken. The calibration data collected in advance creates a reference map that accounts for field inhomogeneities, allowing the system to compensate for variations without adding complexity during operational measurements. This preliminary calibration step resolves the contradiction by preparing correction data beforehand.

The patent introduces an additional dimension of calibration space by collecting data at multiple three-dimensional locations throughout the localization field. This creates a volumetric calibration dataset that maps field characteristics across the entire measurement space, allowing the system to account for inhomogeneities in all spatial dimensions and thereby improve accuracy without proportionally increasing operational complexity.

The patent creates a virtual copy or model of the actual localization field through calibration data. Instead of directly using the complex, inhomogeneous field measurements, the system creates a calibrated reference model that represents the true field characteristics. This copied model can then be used for simplified calculations while maintaining accuracy, resolving the contradiction between computational simplicity and measurement precision.

The patent transforms the raw localization field characteristic measurements into corrected position parameters using calibration data. By changing the parameter representation from direct field measurements to calibration-corrected coordinates, the system simplifies subsequent calculations while accounting for field inhomogeneities, thereby resolving the contradiction between computational ease and measurement accuracy.
