1. A platform for providing information for updating a map, the platform is configured to:
transmit location information to a server;
capture an image by using a camera in a dash cam or a camera in each of the user terminals;
activate an area in which a preset update cycle has been exceeded to an area in which information is updatable;
transmit the image captured by the user terminal to the server when the location information from the user terminal received by the server is detected as that of the area in which information is updatable;
extract map information comprising store information and terrain information from the image and to compare the map information with map information included in an existing map stored in the server to extract changed map information; and
update the existing map with the changed map information,
wherein the platform is further configured to:
divide the existing map into specific areas based on roads and set an update cycle for each of the specific areas to update the map information;
request a consent for transmitting the image to a first user who first entered an activated area of the specific areas, and deactivate the activated area when the user consents;
train a first artificial neural network by using a plurality of images or videos with differences in map information as input values, and the differences in the map information as output values,
train a second artificial neural network with images or videos labeled with the map information including store names, store contact information, terrain, and building exterior as input values, and the map information as output values,
deactivate the activated area when the map information of the activated area is updated,
not request the consent for transmitting the image to a second user when the first user has already consented to image transmission, and
reset the update cycle when the activated area is deactivated.
