Abstract
A method of determining a position of a first object includes receiving a first component and a second component of a vector field jointly generated by the first object and by a second object. The method further includes using the second component of the vector field to provide a compensation quantity indicating a contribution of the second object to the first component of the vector field. Further, the method includes determining the position of the first object using the first component of the vector field and the compensation quantity.
Claims17
A method of determining a position of a first object in a positioning system, the method comprising:
- receiving, by at least one sensor, a first component and a second component of a vector field jointly generated by the first object and by a second object;
- determining, by at least one processor, a compensation quantity indicating a contribution of the second object to the first component of the vector field, wherein the compensation quantity is determined using the second component of the vector field;
- and
- determining, by the at least one processor, the position of the first object using the first component of the vector field and the compensation quantity.
A positioning system, comprising:
- a first magnet and a second magnet jointly generating a magnetic field;
- a first optical element connected to the first magnet and a second optical element connected to the second magnet;
- and
- at least one sensor configured to detect a first component and a second component of the magnetic field.
A non-transitory computer-readable medium comprising a computer program having a program code for causing a programmable hardware device to execute a method of determining a position of a first object in a positioning system, the method comprising:
- receiving sensor signals generated by at least one sensor, the senor signals corresponding to measurements a first component and a second component of a vector field jointly generated by the first object and by a second object;
- determining a compensation quantity indicating a contribution of the second object to the first component of the vector field, wherein the compensation quantity is determined using the second component of the vector field;
- and
- determining the position of the first object using the first component of the vector field and the compensation quantity.
