The signpost extractor 70 matches the signpost position coordinates according to the location where the signpost is installed and one direction vector among a plurality of preset direction vectors corresponding to a plurality of directions, respectively, to generate a plurality of pre-stored in the signpost storage units 60. One of the milestone images may be extracted and output based on the second location coordinates (S109).

The milestone extraction unit 70 calculates the distance between each milestone location coordinate matched to a plurality of pre-stored milestone images and the second location coordinate, and ranks the distances in order of shortness to a preset rank (for example, 4th place). The milestone image may be extracted and output (S109).

In addition, the milestone extractor 70 outputs one of the milestone images up to a preset rank according to the vector similarity of the direction vector and direction judgment vector matched to each of the milestone images up to the preset rank. (S109).

The milestone extraction unit 70 calculates the cosine similarity of the direction vector and the direction judgment vector matched to each of the milestone images up to the preset rank, thereby generating the vector of the direction vector and direction judgment vector matched to each of the milestone images up to the preset rank. Similarity may be calculated (S109).

The cosine similarity of the direction vector and the direction judgment vector can be calculated using the equation below.

Here, A may be a direction vector matched to each milestone image and B may be a direction judgment vector.

The cosine similarity of two different vectors is closer to 1 when the directions of the two different vectors are similar, and can be calculated as 0 when the two vectors are orthogonal, and -1 when the directions are opposite to each other.

The milestone extraction unit 70 calculates the cosine similarity of the direction vector and direction judgment vector matched to each of the milestone images up to a preset rank, subtracts the cosine similarity from the calculated preset reference value (for example, 1), and calculates the cosine similarity to the preset reference value (for example, 1). The vector similarity for the direction vector matched to each milestone image up to the ranking may be calculated (S109).

In addition, the milestone extractor 70 may select and output the milestone image with the smallest vector similarity calculated for the matched direction vector among the milestone images up to a preset rank (S109).

According to the above-described configuration, the milestone extractor 70 can extract a milestone that the user can encounter when moving in the drag-and-drop direction among the milestones close to the point released by the user's drag-and-drop input.

For example, when the user's drag and drop input is released at a point where the road is divided into several branches, such as an intersection, the signpost extractor 70 generates a signpost image around the point where the drag and drop input was released based on the distance. It may be possible to first extract a plurality of , and then finally output a milestone image that has high similarity to the direction of the drag and drop operation.

In other words, by extracting milestones considering both the location where the drag and drop input is released and the drag direction, it is possible to extract milestones that the user may encounter when moving in reality in the drag direction.

Therefore, it is possible to further enhance the realism of the virtual space and provide a guidepost that allows users to improve their understanding of the space by considering real geography when determining the location.

The interface control unit 10 may display the milestone image output from the milestone extractor 70 in response to the drag and drop input on the screen of the terminal to which the user has been granted (S111) after receiving the drag and drop input. ).

After receiving the drag-and-drop input, the interface control unit 10 receives the milestone image output from the milestone extractor 70 in response to the drag-and-drop input, and creates a virtual milestone display area 1100 for displaying the milestone image. The space may be displayed by overlapping it at a preset position on the screen 1000 (S111).

According to the present invention, a virtual space where actual roads and facilities corresponding to latitude and longitude are displayed is displayed on the screen of the user's terminal, and a milestone image is provided according to the user's drag and drop operation on the screen and displayed on the screen. It allows users to easily figure out which location in reality the virtual space corresponds to.

In addition, according to the present invention, by providing a signpost image based on the similarity with the direction of the drag and drop input as well as the location where the drag and drop input is released, the user can check when moving on the road in the same direction as the user's operation direction. It is possible to provide location guidance with a high level of realism by providing signpost images.
