Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 6:
7. An electronic device comprising:
at least one sensor configured to obtain 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;
a memory storing one or more instructions; and
a processor configured to execute the one or more instructions stored in the memory to:
obtain location information with respect to each of the generated nodes based on the image data of the second resolution;
generate map data by matching the obtained location information with the image data of the first resolution for each node;
store the generated map data in the memory; and
estimate a current location of the electronic device based on the generated map data and the image data of the first resolution

wherein the processor is further configured to:
obtain 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
obtain the location information of the second node from the location information of the first node, based on the obtained at least one of the difference value and the covariance of the pose information.
