1. A method, performed by an electronic device, of performing object recognition, the method comprising:
obtaining a spatial map of a space;
using a first recognition model, recognizing a plurality of objects in the space, to obtain first object information of the plurality of objects;
dividing the space into a plurality of unit spaces, based on the obtained spatial map, wherein each unit space has a same shape and a same size;
grouping, into a plurality of groups, the plurality of unit spaces into which the space is divided, based on the obtained first object information;
setting a plurality of subset spaces so that each of the plurality of subset spaces comprises one or more of the plurality of unit spaces that are grouped into a same group among the plurality of groups;
determining at least one second recognition model to be allocated to each of the plurality of subset spaces into which the space is divided, based on characteristic information of each of the plurality of subset spaces; and
using the determined at least one second recognition model allocated to each of the plurality of subset spaces, performing object recognition on each of the plurality of subset spaces, to obtain second object information.
