Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 3:
4. An electronic device comprising:
a first sensor configured to obtain an image of a structure of a surface or a structure of a subsurface of the surface;
at least one second sensor configured to obtain surrounding environment information of the electronic device;
a memory storing a program including at least one instruction; and
at least one processor configured to execute the at least one instruction stored in the memory to cause the at least one processor to:
control the first sensor to emit a first signal in a direction of the surface,
receive a second signal reflected from the structure of the surface or the structure of the subsurface,
based on the second signal, obtain the image of the structure of the surface or the structure of the subsurface,
determine whether there is a correlation between the obtained image and an image among at least one of images pre-stored in the memory, wherein each of the at least one of images pre-stored in the memory includes corresponding location information,
in response to determining that there is a correlation between the obtained image and the image pre-stored in the memory, determine a location of the electronic device based on the corresponding location information included in the image pre-stored in the memory, and
in response to determining that there is no correlation between the obtained image and the at least one of images pre-stored in the memory, determine the location of the electronic device by using the surrounding environment information obtained through the at least one second sensor, and store the obtained image including the determined location as the corresponding location information,

wherein the first sensor comprises at least one of a ground-penetrating radar (GPR) sensor or a surface-penetrating radar (SPR) sensor.
