ABSTRACT

The present disclosure relates to the technical field of robots, and in
particular, discloses a map alignment method. The method includes the
following steps: acquiring boundary information of a map, wherein the boundary
information includes state information of boundary lines and a total boundary
length, and the total boundary length is a sum of lengths of all the boundary
lines; classifying all boundary lines that meet a preset condition into one
orthogonal line group; determining a relationship between a reference ratio
and a determination threshold, if a first relationship is met, establishing a
plane Cartesian coordinate system according to a first reference, and if a
second relationship is met, establishing a plane Cartesian coordinate system
according to a second reference, wherein the reference ratio is a ratio of a
maximum boundary line length to the total boundary length, with the boundary
line length being defined as a sum of lengths of all boundary lines within one
orthogonal line group; and aligning the map according to the plane Cartesian
coordinate system, and outputting the boundary information of the aligned map
to a user terminal. The method decides the plane Cartesian coordinate system
by determining the reference ratio, thus achieving the alignment of the map.
