1. A system for positioning, comprising:
at least one non-transitory storage medium storing a set of instructions; and
at least one processor in communication with the at least one storage medium, when executing the stored set of instructions, the at least one processor causes the system to:
obtain estimated pose data of a subject;
generate a local map associated with the estimated pose data;
obtain, based on the estimated pose data, a reference map;
determine a cross power spectrum between the local map and the reference map in a frequency domain;
convert the cross power spectrum between the local map and the reference map in the frequency domain to a spatial domain;
determine, based on the cross power spectrum between the local map and the reference map in the spatial domain, an offset between the local map and the reference map; and
determine, based on the estimated pose data and the offset, target pose data of the subject to navigate the subject.
