display, on the display, the map,

change a first image of the map associated with the first node among the at least one node or first additional information on the first image, in response to an input or an event for changing information of the first node,

display, on the map through the display, the changed first image or the changed first additional information associated with the first node, and

display the first path associated with the changed first image or the changed first additional information,

wherein adjacent nodes within a predetermined distance of the at least one node are combined into one node.

2. The device of claim 1 , wherein the processor is further configured to:

display, on the display, the first image including a pre-configured area;

detect a selection of the pre-configured area; and

output, in response to the selection, attribute information of an object displayed on the first image through the display.

3. The device of claim 1 , wherein the processor is further configured to display, in response to the input or a direction change of the electronic device, a graphic element associated with the first node.

4. The device of claim 1 , wherein the processor is further configured to:

detect an occurrence of the event;

acquire, in response to the occurrence of the event, a graphic element associated with the first node from an external device; and

display the graphic element on the display.

5. The device of claim 1 , wherein the processor is further configured to:

detect the occurrence of the event; and

replace, in response to the occurrence of the event, the first path with a second path that connects another node among the at least one node.

6. The device of claim 1 , wherein the processor is further configured to:

acquire, from an external device or an object, information on the object displayed on the first image; and

display information on the object on the display.

7. The device of claim 1 , wherein the processor is further configured to:

acquire control information on an object displayed on the first image;

display the control information on the object; and

control the object, in response to an input or an event associated with the displayed control information.

8. The device of claim 1 , wherein the processor is further configured to:

store a message on an object displayed on the first image; and

display the message or an indicator of the message on the display.

9. The device of claim 1 , wherein the processor is further configured to:

transmit, to an external device, a message or a tag on an object displayed on the first image; and

display information associated with the transmission or reception of the message or the tag on the display.

10. An electronic device for providing map information associated with a space of interest, the electronic device comprising:

a camera configured to acquire at least one image; and

a controller, functionally connected to the camera, configured to:

determine at least one position where the at least one image is photographed as at least one node,

determine the at least one path connecting between the at least one node based on a photographing direction and depth information of the at least one image photographed at the at least one node, and

generate a map including the at least one node and the at least one path, by combining the at least one image,

wherein the at least one node comprises a first node which is a first position where a first image is photographed and a second node which is a second position where a second image is photographed, the at least one path comprising a first path connecting the first node and the second node, and the first path is determined based on a first photographing direction and depth information of the first image and a second photographing direction and depth of the second image, and

wherein the contoller combines adjacent nodes within a predetermined distance of at least one node into one node.

11. The device of claim 10 , wherein the at least one node comprises 3D information determined by comparing image data of at least a part of an area of the first image and image data of at least a part of an area of the second image.

12. The device of claim 10 , wherein the controller is further configured to:

identify a photographing position of the camera or a photographing direction of the camera for the at least one image; and

display, based on at least one of the photographing position or the photographing direction, a photographing guide on a screen functionally connected to the electronic device.

13. The device of claim 10 , wherein the controller is further configured to:

acquire another image through the camera;

generate, when there is no node corresponding to the another image among the plurality of nodes, a node corresponding to the another image; and

dispose the another image in a space of the generated node.

14. The device of claim 10 , wherein the controller is further configured to:

switch, in response to a user input with respect to the electronic device, at least a part of the at least one image corresponding to the first node into at least a part of the at least one image corresponding to the second node, and

display the switched image on a screen functionally connected to the electronic device.

15. The device of claim 10 , wherein the controller is further configured to display, in response to a user input with respect to the electronic device, visual information corresponding to at least one of the first node or the second node on a screen functionally connected to the electronic device.

16. The device of claim 10 , wherein the controller is further configured to:

determine the ground or an obstacle of the first node and the second node, based on the 3D information; and

generate a planar map that connects the first node and the second node, based on the ground or the obstacle.
