Claim 19:
20. A non-transitory computer readable medium storing instructions, the instructions, when executed by at least one processor, causing the at least one processor to implement a method comprising:
obtaining estimated pose data of a subject;
generating a local map associated with the estimated pose data;
obtaining, based on the estimated pose data, a reference map;
determining a cross power spectrum between the local map and the reference map in a frequency domain;
converting the cross power spectrum between the local map and the reference map in the frequency domain to a spatial domain;
determining, 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
determining, based on the estimated pose data and the offset, target pose data of the subject to navigate the subject.
