| 发明名称 | Calibration of a triaxial magnetic field sensor | ||
| 摘要 | A method for calibrating a triaxial magnetic field sensor includes steps for determining an offset of recorded measured values of the magnetic field sensor using a superposed signal and for determining the sensitivity of the magnetic field sensor along the first measuring axes. The determination of the sensitivity includes steps for determining the sensitivity of the magnetic field sensor along a first measuring axis and for determining the sensitivity of the magnetic field sensor along the other measuring axes based on the sensitivity of the first measuring axis and the determined offset. | ||

| 主权项 | 1. A method for calibrating a triaxial magnetic field sensor, comprising: determining, with a processor, an offset of recorded measured values of the magnetic field sensor using a superposed signal; and determining, with the processor, a sensitivity of the magnetic field sensor along measuring axes; wherein the determination of the sensitivity includes determining the sensitivity of the magnetic field sensor along a first measuring axis, and determining the sensitivity of the magnetic field sensor along the other measuring axes based on the sensitivity along the first measuring axis and the determined offset, and wherein the sensitivity along the other measuring axes is determined using a Newton iteration method. | ||
