METHOD AND SYSTEM FOR PROVIDING USER INTERFACE FOR MAP TARGET CREATION

1 . A method of providing a user interface for map target creation through a map target application executed by at least one processor of a terminal, the method comprising:

acquiring an image captured by photographing a 3D space;

extracting a key frame of the captured image;

detecting feature points in the extracted key frame;

generating a 3D map based on the detected feature points;

generating object information including class information and object area information for at least one key object in the key frame;

mapping the generated object information to the 3D map;

displaying the object information mapped on the 3D map; and

providing an object function setting interface based on the 3D map.

2 . The method of claim 1 , wherein the object function setting interface is a user interface for selecting a specific object or an object of a specific class from map objects in the 3D map and setting a function operation based on the selected map object.

3 . The method of claim 1 , wherein the extracting of the key frame comprises:

extracting a multi-view key frame according to a positional change of a sensor that senses the 3D space.

4 . The method of claim 1 , wherein the generating of the object information comprises:

generating object information for each key object by performing semantic segmentation based on the key frame.

5 . The method of claim 2 , wherein the mapping of the object information to the 3D map comprises:

detecting a first map object corresponding to a first key object; and

mapping the detected first map object and object information of the first key object.

6 . The method of claim 5 , wherein the mapping of the object information to the 3D map further comprises:

extracting a first feature point group constituting the first map object from among a plurality of feature points in the 3D map; and

mapping the extracted first feature point group and the object information of the first key object.

7 . The method of claim 2 , wherein the displaying of the object information mapped on the 3D map comprises:

classifying the object information according to object information mapped to each map object in the 3D map; and

displaying classified object information.

8 . The method of claim 2 , further comprising:

executing a map object-based functional operation set through the object function setting interface.

9 . A system for providing a user interface for map target creation, the system comprising:

at least one display for outputting a 3D map;

at least one memory;

at least one processor; and

at least one application stored in the memory and executed by the processor to provide the user interface for map target creation,

wherein the at least one application is operated to:

acquire an image captured by photographing a 3D space;

extract a key frame of the captured image;

detect feature points in the extracted key frame;

generate a 3D map based on the detected feature points;

generate object information including class information and object area information for each key object in the key frame;

map the generated object information to the 3D map;

display the object information mapped on the 3D map; and

provide an object function setting interface based on the 3D map.

10 . The system of claim 9 , wherein the application is operated to extract a multi-view key frame according to a positional change of a sensor that senses the 3D space.
