Description

Technical Field [0001] The present invention relates to a method and system for generating an intelligent location-

The present invention relates to a method and system for generating location-based intelligent photographs indoors.

Generally, in the case of construction work, on-the-spot photographed on-site is used as a means of managing construction such as safety management, defect management, and established management. In other words, site photos are used as proof and proof for construction management. However, in order to use the site photographs as construction management means, the safety personnel, quality inspection and surveillance personnel visit the construction sites directly, take pictures of the places where there are problems or facilities, The place where the on-site photographs were taken and the degree of the ready-made photographs should be prepared separately and written as a report.

In order to grasp the design information of the site on the site, such construction management should be provided separately for the drawings, and since the location information of the site photographs must be grasped and the location information must be directly created, the productivity may be deteriorated. Automation of the report may be difficult due to lack of information on design information and location information.

In case of registering the location and design information as meta data, it is possible to improve efficiency. However, it is not possible to generate location based photographs in the room where GPS (Global Positioning System) information can not be used. In the case of indoor construction, a QR code (Quick Response code) including location information is provided for each location and can be used for photographing. However, when a wall or a door is not installed at the beginning of construction, It is also difficult to utilize, and the QR code needs to be attached and managed separately, which may also reduce efficiency.

Referring to FIG. 1, there is shown a configuration diagram of a location-based intelligent photo generation system in an indoor environment according to an exemplary embodiment of the present invention. Referring to FIG. 2, a flowchart illustrating a method of generating a location-based intelligent photograph in a room using the location-based intelligent photo generating system in the room of FIG. 1 is shown. Hereinafter, a system and method for generating a location-based intelligent photograph in a room will be described with reference to FIGS. 1 and 2. FIG.

1, the location-based intelligent photo generation system 100 includes a location map generator 111, a design terminal 110 including a memory 112, a location map generator 111, And a user terminal 120 for receiving the generated location map and generating a location based photo.

The design terminal 110 may be a workstation used as a personal computer terminal or a server provided in the design office. In addition, the memory 112 may be a memory included in the design terminal 110, and the memory 112 may include a plurality of design drawings for a construction site, a location map generated by the location map generation unit 111, A scene photograph transmitted from the terminal 120, and the like can be stored.

The position map generating unit 111 includes a plan view extracting unit 111a for extracting a plan view from the CAD drawing, a model information extracting unit 111b for extracting model information from the CAD drawing, And a position map compression unit 111c.

The location map generating unit 111 receives a design drawing such as a structural drawing, a building drawing, and an equipment drawing for a building or civil engineering work from the memory 112, extracts the floor plan and model information, and generates a location map . Here, the design drawing may be a drawing constructed through a CAD program. The location map generating unit 111 may generate the location map through the design diagram stored in the memory 112 of the design terminal 110. [

In addition, the location map generator 111 may execute a dedicated program for generating the location map in the design terminal 110, and then extract the floor plan and the model information from the design drawing. For example, when the design drawing is a drawing for a building construction, the location map generating unit 111 generates a plurality of models for a plurality of layers of the building and a plurality of models Respectively. Hereinafter, the case where the design drawing is a building drawing will be described in detail.

The plan view extraction unit 111a of the position map generation unit 111 extracts a plan view of the tile view format from the design drawing. At this time, the plan view extraction unit 111a may extract a plan view of the tile view format for each layer of the building.

Here, for example, a tile having a coordinate (0, 0) is located at the upper left corner of the drawing, and the x value increases from left to right, and the y value decreases from the top to the bottom . In general, each time the magnification level of the tile increases, the magnification of the x and y values increases by a multiple of 2, and the size of the tiles may be the same. For example, if the floor plan is rendered in one tile at the magnification level of 0, the tiles of the grid of 2 * 2 are rendered when the magnification level is 1. If the magnification level is 2, the tiles of the grid of 4 * 4 grid are rendered , And when the magnification level is 3, a tile of 8 * 8 grid can be rendered.

The model information extracting unit 111b of the location map generating unit 111 extracts a plurality of model information of the GeoJSON format for each layer of the building from the design drawing.

For example, the model information may be a column, a staircase, a room, an equipment (facility), a door, a window, a plumbing element and a configuration that can be included in the corresponding building. The GeoJeason format also refers to a Geospatial Data Interchange Format based on JavaScript Object Notation (JSON) and is a format for encoding location data structures. Such model information means building information modeling (BIM) data including location and design information.

The position map compressing section 111c of the position map generating section 111 compresses the model information extracted by the model information extracting section 111b to be displayed on the plan view on the plan view extracted by the plan view extracting section 111a, do. That is, the location map compression unit 111c merges and compresses the hotspots containing the model information so as to be displayed in the plan view, and generates the location map. Here, the hot spot including the model information is displayed at the position corresponding to the position of the model information in the plan view. In this manner, the location map generation unit 111 can generate a location map for each layer of the building from the design drawing (S1).

In this way, the location map generator 111 can transmit the generated location map information to the user terminal 120.

The location map provided to the user terminal 120 may be provided as a deep zoom image that can be enlarged and reduced by the user's control. For example, the user can magnify and reduce the displayed position map through motion using the position map display unit 121. [ In addition, the location map displayed on the location map display unit 121 may be provided with hotspots H containing model information for different levels. The hotspot H displayed in the location map and the model information included in the hotspot H may be as shown in Table 1.

Magnification level Displayed hotspots Model information included in the hotspot 0 none none One Main column, staircase Layer, location, column number, stair blindness 2 Room, equipment (facility) Floor, location, real name, use, facility name, equipment number 3 Doors, windows, plumbing elements Floor, location, door number, window number, piping element tag

As shown in Table 1, when the magnification level of the position map displayed on the position map display unit 121 is 0, there may be no hot spot H to be displayed. In addition, when the magnification level of the position map displayed on the position map display unit 121 is 1, the main column (column) and the hot spot H for the staircase can be displayed. Also, the model information included in the hot spot H may include a layer, a location, and a column number if the hot spot H for the main column, and a layer, a location, and a stair real name if the hot spot H for the stair room.
