Claim 0:
1. An operating method of an electronic device, the method comprising:
obtaining image data of a first resolution and image data of a second resolution for each of a plurality of nodes generated while the electronic device moves;
obtaining location information with respect to each of the generated nodes based on the image data of the second resolution;
generating and storing map data by matching the obtained location information with the image data of the first resolution for each node; and
estimating a current location of the electronic device based on the generated map data and the image data of the first resolution,
wherein the obtaining the location information with respect to each of the generated nodes comprises:
obtaining at least one of a difference value and a covariance of pose information of the electronic device between a first node and a second node, based on the image data of the second resolution; and
obtaining the location information with respect to the second node from the location information with respect to the first node, based on the obtained at least one of the difference value and the covariance of the pose information.
