Electronic apparatus and control method thereof

An electronic apparatus comprising:

• memory storing one or more computer programs;
• and
• one or more processors communicatively coupled to the memory,
• wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic apparatus to:
• obtain a LiDAR map prestored in the memory for estimating a location of the electronic apparatus, based on an event for obtaining the location of the electronic apparatus occurring,
• obtain geomagnetic information around the electronic apparatus using a geomagnetic sensor,
• identify a direction of the electronic apparatus based on the obtained geomagnetic information, and
• search the location of the electronic apparatus on the LiDAR map using a LiDAR sensor based on the electronic apparatus being within a predetermined range radius from the identified direction,
• wherein the one or more computer programs further include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic apparatus to:
• obtain a geomagnetic map around the electronic apparatus using the geomagnetic sensor,
• identify the direction of the electronic apparatus on the LiDAR map and at least one second estimated location by matching geomagnetic size information and direction information included in the obtained geomagnetic map with the geomagnetic information, and
• search the location of the electronic apparatus on the LiDAR map through the LiDAR sensor based on the direction of the electronic apparatus on the LiDAR map and the at least one second estimated location, and
• wherein the electronic apparatus is configured to travel to an area where the electronic apparatus intends to generate a geomagnetic map.
