Driving robot generating driving map and controlling method thereof

A method of controlling a driving robot, the method comprising:

• acquiring depth data in one or more areas where the driving robot moves;
• identifying, from the acquired depth data, a plurality of scan data sets corresponding to a plurality of predetermined height levels;
• identifying, based on the plurality of scan data sets, a plurality of feature scores corresponding to the plurality of scan data sets;
• generating at least one area map corresponding to at least one scan data set among the plurality of scan data sets based on the plurality of feature scores;
• comparing the plurality of scan data sets with the at least one area map;
• and
• identifying a current position of the driving robot based on an area map, among the at least one area map, matching the plurality of scan data sets or having a highest similarity to the plurality of scan data sets.

A non-transitory computer-readable storage medium having instructions stored therein, which when executed by at least one processor cause the at least one processor to execute a method of controlling a driving robot, the method comprising:

• acquiring depth data in one or more areas where the driving robot moves;
• identifying, from the acquired depth data, a plurality of scan data sets corresponding to a plurality of predetermined height levels;
• identifying, based on the plurality of scan data sets, a plurality of feature scores corresponding to the plurality of scan data sets;
• generating at least one area map corresponding to at least one scan data set among the plurality of scan data sets based on the plurality of feature scores;
• comparing the plurality of scan data sets with the at least one area map;
• and
• identifying a current position of the driving robot based on an area map, among the at least one area map, matching the plurality of scan data sets or having a highest similarity to the plurality of scan data sets.
