Abstract

Disclosed herein is a method of generating a digital interior map. The method includes applying a coordinate system for a drawing of an interior of a structure using an electronic device, extracting center coordinate information of each sectional space of the interior of the structure and entrance coordinate information of entrances between floors and from an outside, generating, in the drawing, a circulation path in the interior of the structure, extracting interest points at preset intervals along the circulation path in the interior of the structure, and setting coordinate information and attribute information of each of the interest points.

Claims

1. A method of generating a digital interior map, comprising:

applying a coordinate system for a drawing of an interior of a structure;

extracting center coordinate information of each sectional space of the interior of the structure and entrance coordinate information of entrances between floors and from an outside;

generating, in the drawing, a circulation path in the interior of the structure;

extracting interest points at preset intervals along the circulation path in the interior of the structure; and

setting coordinate information and attribute information of each of the interest points.

2. The method as set forth in claim 1, wherein the drawing of the interior of the structure is a plan view of each of the floors of the structure.

3. The method as set forth in claim 1, wherein the circulation path in the interior of the structure comprises a plurality of closed loops and a single-line circulation path connected to the closed loops.

4. The method as set forth in claim 1, wherein the generating the circulation path in the interior of the structure comprises generating circulation paths for walking, spaced apart from the boundaries of each sectional space by a preset interval, within one or more sectional spaces or areas including a corridor and a passage through which a walker may pass.

5. The method as set forth in claim 4, wherein the generating a circulation path in the interior of the structure comprises:

generating a circulation path for entrances along centers of entrances between the floors and from the outside; and

connecting the circulations path for walking and the circulation path for entrances.

6. The method as set forth in claim 1, wherein the extracting coordinate information comprises:

setting one point of the drawing as a reference point; and

forming an orthogonal coordinate system based on the reference point.

7. The method as set forth in claim 6, wherein the center coordinate information, the entrance coordinate information, and the coordinate information of the interest points each comprise coordinate information, floor information, and azimuth information based on the orthogonal coordinate system.

8. The method as set forth in claim 1, wherein the extracting coordinate information comprises:

extracting coordinate information of a center point of a rectangle, including each of the sectional spaces, as the center coordinate information of the sectional space; and

extracting coordinate information of a center point of the entrance as the entrance coordinate information of the entrance.

9. The method as set forth in claim 1, wherein the attribute information of the interest point is information about a sectional space or an entrance adjacent to the interest point.

10. The method as set forth in claim 9, wherein the attribute information of the interest point comprises one or more of a plurality of pieces of information about a name, type of business, contact information, representative, homepage link and details of a service of the sectional space adjacent to the interest point.

11. The method as set forth in claim 9, wherein the attribute information of the interest point comprises information about another floor and information about one or more external structures that are connected to the entrance adjacent to the interest point.

12. The method as set forth in claim 1, further comprising updating the drawing or the attribute information periodically or whenever input is performed by a server.
