Abstract
In one embodiment, a method includes generating navigation or localization information based on a combination of first data that are based on first measurements of a magnetic field by one or more magnetic sensors and second data that are based on second measurements by one or more other sensors. The method includes determining an anomalousness of a magnetic field and, based on the determined anomalousness of the magnetic field, at least temporarily adjusting a weight of the first measurements relative to the second measurements in the generation of the navigation or localization information.
Claims43
A method comprising:
- by an electronic device, generating navigation or localization information based on a combination of:
- first data that are based on first measurements of a magnetic field by one or more magnetic sensors;
- and
- second data that are based on second measurements by one or more other sensors;
- by the electronic device, determining an anomalousness of a magnetic field;
- and
- by the electronic device, based on the determined anomalousness of the magnetic field, at least temporarily adjusting a weight of the first measurements relative to the second measurements in the generation of the navigation or localization information.
One or more computer-readable non-transitory storage media embodying software that is operable when executed to:
- generate navigation or localization information based on a combination of:
- first data that are based on first measurements of a magnetic field by one or more magnetic sensors;
- and
- second data that are based on second measurements by one or more other sensors;
- determine an anomalousness of a magnetic field;
- and
- based on the determined anomalousness of the magnetic field, at least temporarily adjust a weight of the first measurements relative to the second measurements in the generation of the navigation or localization information.
A system comprising:
- one or more processors;
- and
- one or more computer-readable non-transitory storage media coupled to one or more of the processors and comprising instructions operable when executed by one or more of the processors to cause the system to:
- generate navigation or localization information based on a combination of:
- first data that are based on first measurements of a magnetic field by one or more magnetic sensors;
- and
- second data that are based on second measurements by one or more other sensors;
- determine an anomalousness of a magnetic field;
- and
- based on the determined anomalousness of the magnetic field, at least temporarily adjust a weight of the first measurements relative to the second measurements in the generation of the navigation or localization information.
A system comprising:
- means for generating navigation or localization information based on a combination of:
- first data that are based on first measurements of a magnetic field by one or more magnetic sensors;
- and
- second data that are based on second measurements by one or more other sensors;
- means for determining an anomalousness of a magnetic field;
- and
- means for, based on the determined anomalousness of the magnetic field, at least temporarily adjusting a weight of the first measurements relative to the second measurements in the generation of the navigation or localization information.
