摘要： In a magnetic position detection system designed to detect a target object in a detection space using an array of magnetic sensors, the position of the target object can be determined by fitting a model of the target object's magnetic field to the sensor measurements. A robust determination of whether a target object is present can be obtained by fitting the model to the sensor measurements and determining the remaining differences between the fitted model and the sensor measurements. If the differences are high then the model is not fitting well, suggesting that the target object is not present. If the differences are low, the model is fitting well and the target object can be determined as being present. Measurements made when the target object is determined as not being present can be regarded as background field measurements including any stray fields. These stray fields can then be deducted from subsequent sensor measurements to eliminate the effect of stray fields and allow more accurate determination of the position of the target object. A user indicator may be included to indicate whether stray fields are not present, or present and accurately detected, or whether stray fields are varying.

摘要： A method of obtaining information about the position and/or orientation of a magnetic component relatively to a magnetometric detector, the magnetic component and the magnetometric detector being moveable independently from each other relatively to a static secondary magnetic field, the method comprising the steps of: measuring in the presence of the combination of both the magnetic field of the magnetic component and the static secondary magnetic field essentially simultaneously the strength and/or orientation of a magnetic field at at least a first position and a second position spatially associated with the magnetometric detector, the second position being distanced from the first position; and combining the results of the measurements to computationally eliminate the effect of the secondary magnetic field and derive the information about the position and/or orientation of the magnetic component.
