Abstract
A method of detecting a magnetic field interference includes obtaining magnetic field information measured by each one of n magnetometers carried by a movable object, determining magnetic differences between the magnetic field information measured by m magnetometers of the n magnetometers, and determining whether the movable object is subject to a magnetic field interference based on the magnetic differences. n is an integer greater than or equal to 2, and m is an integer greater than or equal to 2 but smaller than or equal to n.
