Description

Method for generating digital map using electronic digital drawing}

The present invention relates to a method for generating a digital map, and more particularly, to a method for generating a digital map using electronic drawing for more convenient and accurate drawing correction, attribute data input and editing of each area by automating the manual work performed in the digital map production. It is about.

The digital map means that digital maps are produced by digitally analyzing various topographical data obtained by surveying maps, aerial photographs, satellite images, etc. from existing analog paper maps. In general, the process of constructing a digital map is as follows.

First, a paper map is digitized or scanned to generate a drawing in the form of a digital map, and the drawing is converted into an actual coordinate system to suit the user's purpose through coordinate transformation. Then, attribute data is input to the numerical map that establishes the topological structure to grasp the inter-location and correlation between spatial objects. In this case, the attribute data includes various identifier information. For example, a unique feature identifier (UFID) is used as an identifier for a feature of a digital map of the National Geographic Information Institute. It is a single identifier that indicates location information, management authority, other attribute information, etc., and is a unique identifier of a feature, and consists of an organization code, a leaf number, a feature identification code, and a serial number field. It can be used as an identifier for linking with other geographic information or for cross-reference between features.

However, since the generated drawing is input through aerial photographs and satellite image reading, it is difficult to guarantee the accuracy of the drawing feature, and thus, it is difficult to ensure the accuracy of attribute data assigned to each feature.

For this reason, digital map makers produce more accurate digital maps through the process of digital map generation method described in FIG. 1 to ensure the accuracy of digital maps.

Referring to FIG. 1, a digital map maker prints a drawing generated through digitizing or scanning such as surveying maps, aerial photographs, and satellite images on paper (S10), and the corresponding area of the printed drawing. Perform a site survey to (S20).

In addition, attribute data such as the name of the artificial and natural topography, name, and basic information (such as the number of floors of a building, the width of a road or a river) shall be manually marked at the corresponding position of the drawing.

When the marking of the artificial features and natural topography that are incorrectly depicted in the drawing through the field survey and the property data of each artificial feature and the natural topography is completed, the changed information is applied to the first generated drawing through computerization using the marked drawing. And by modifying and supplementing the drawing and map input performance by displaying the attribute data, and performs the exact position editing to determine the geographical correlation of the terrain, features (S30).

Then, the terrain, features edited through the in-situ editing are composed in geometric form, and the points, lines, and plane shapes defined by the National Geographic Information Institute as geometric models of points, lines, faces, and network area segmentation, or a combination of them. On the basis of the painting, a structured edit is performed to manually display and edit the corresponding artificial features and natural terrain by computerization (S40). At this time, in the structured editing, the attribute data displayed in the drawing is edited in a hidden state (not stored on the screen).

When the structured editing is completed as described above, the digital map is produced and printed using a software program provided by the National Geographic Information Institute and provided to the National Geographic Information Institute requesting the digital map production (S50).

The real artifacts and natural topography currently photographed by the photographing unit 120 are matched with the artificial features and natural topography generated in the electronic drawing stored in the storage unit 180 in real time. In this case, the matching unit 150 preferably matches attribute information of the artificial feature and the natural feature of the electronic drawing stored in the storage unit 180 together with the artificial feature and the natural feature using coordinate values.

The display unit 160 displays the photographed artificial feature and the natural feature and the electronic feature of the artificial feature and the natural feature which are provided by matching the matcher 150 on the screen. At this time, any one or both of the photographed artificial features and natural topography and the artificial features and natural topography of the electronic drawing are partially transparent (between 20% and 80% when defining transparency as 100% and opacity as 0%). Display the artificial artifacts and natural features on one screen, and display the artificial features and natural features of the electronic drawing on one screen, respectively, on one screen, or on two separate screens. You may. Alternatively, the screen can be displayed by using the above two methods through three separate screens.

Like reference numerals in FIG. 2 refer to like elements performing the same function.

3 is a flowchart illustrating a method for generating a digital map using electronic drawing according to an embodiment of the present invention.

Referring to FIG. 3, first, the system server 200 for producing a digital map produces a drawing through digitizing or scanning surveying maps, aerial photographs, satellite images, etc. provided by the National Geographic Information Institute. Then, the attribute information and the position coordinate value information are inserted into the artificial feature and the natural terrain displayed in the produced drawing to generate a filed electronic drawing (S100).

Then, the generated electronic drawing is stored in the digital map generating terminal 100 and moved to the corresponding area of the electronic drawing stored in the digital map generating terminal 100 for the field survey (S200). In this case, the digital map generating terminal 100 may be a terminal having a size and weight that can be carried by the digital map maker, but is not limited thereto. If the volume and weight are not suitable for carrying, it is impossible to carry the electric apparatus ( It may be attached or carried by a car, motorcycle, etc.).

Subsequently, various artificial features and natural topography such as buildings, roads (paved, unpaved), railroads, parks, rivers, mountains, rice fields, fields, etc., were taken from the field survey through the photographing unit 120 in the digital map generation terminal 100. Take a picture (S300).

In addition, the position coordinate value of the location currently being photographed by the photographing unit 120 using a position measuring network capable of measuring a position such as a GPS or a base station through the measurement unit 130 in the digital map generating terminal 100 is real-time. The location coordinate values of the artificial feature and the natural topography photographed by measuring are calculated in real time (S400).

Then, the measurement unit 130 is scanned by the search scan unit 140 in the digital map generating terminal 100 by using the pattern matching algorithm on the scanned image of the artificial feature and the natural terrain photographed by the photographing unit 120. The measured coordinates are applied to search the area and the location of the photographed artificial feature and natural feature (S500). In this case, the pattern matching algorithm is a pattern matching method for detecting and displaying building and street information on a screen through a search scan using a GPS currently used in a smartphone.

Then, an electronic drawing having coordinates stored in the storage unit 180 and coordinate values of artificial and natural features searched by the search scan unit 140 through the matching unit 150 in the digital map generating terminal 100. By comparing the coordinate values of the artificial features and natural features currently photographed in the photographing unit 120 and the artificial features and natural features generated in the electronic drawing stored in the storage unit 180 is matched with each other in real time (S600).

At this time, the error compensator 182 in the controller 180 detects the difference between two coordinate values measured at the time of real-time matching through coordinate values in real time and compensates for the detected difference to control more accurate matching. .

In the compensation method, first, the coordinate values of the photographed artificial feature and the natural feature according to a point are called (x, y), and the coordinate values of the artificial feature and the natural feature generated in the electronic drawing are (x ', y'). ), The x coordinate value A which is the value of the difference between the x coordinates (| x-x '|) and the y coordinate value B of the difference between the y coordinates (| y-y' |) are calculated, As shown in Equation 1, the difference between the x coordinate value and the y coordinate value is corrected to have the x coordinate and the y coordinate having the smallest value (C).

Subsequently, when the drawing correction of the artificial feature and the natural terrain is requested through the input unit 170 (S700), the matching unit 150 is provided to match through the display unit 160 in the digital map generating terminal 100. The artificial feature and the natural feature and the artificial feature and the natural feature of the electronic drawing are displayed on the screen (S800). In this case, any one or both of the photographed artificial features and natural features and the artificial features and natural features of the electronic drawing are partially transparent (between 20% and 80% when defining transparency as 100% and opacity as 0%). Display the artificial artifacts and natural features on one screen, and display the artificial features and natural features of the electronic drawing on one screen, respectively, on one screen, or on two separate screens. You may. Alternatively, the screen can be displayed by using the above two methods through three separate screens.

Subsequently, the digital map maker searches the artificial features and natural features of the electronic drawing displayed on the display unit 160 by matching the artificial features and natural features photographed in real time through the photographing unit 120, and preferably uses the touch screen formed on the screen. By applying a touch method (of course, input using a mouse or an external input means), the error between the photographed artificial feature and natural feature and the artificial feature and natural feature of the electronic drawing (size of building / road, etc.) And the case of different widths, etc.) and differences (such as buildings / roads or the like), which are inputted through the editing unit 184 in the controller 180 when the touch fan is changed through addition / delete / modification. Based on the addition / deletion / modification of the artificial features and natural topography, the digital map contents stored in the storage unit 190 are edited as changes, and the digital map DB 192 in the storage unit 190 is edited. And stores, as well as storing the information thus changed, the change information DB (198) in the storage unit (190) (S900).

In addition, when the modification of the attribute information of the artificial feature and the natural topography is requested through the input unit 170 in the digital map generating terminal 100 (S700), the wireless communication network through the communication interface 110 in the digital map generating terminal 100 is requested. The photographed artificial feature provided by matching with the matching unit 150 by connecting to an external server such as the National Geographic Information Institute, Korea Expressway Corporation, and facility information integrated management system (http://fms.kistec.or.kr). And attribute information (the trade name, name, and basic information of the artificial land and the natural topography, the number of floors of the building, the width of the road or the river, etc.) according to the artificial and natural topography of the natural topography and the electronic drawing (S1000).

In addition, the display unit 160 in the digital map generating terminal 100 displays the photographed artificial features and natural features and the artificial features and natural features of the electronic drawing provided on the screen in operation S1100. . At this time, any one or both of the photographed artificial features and natural topography and the artificial features and natural topography of the electronic drawing are partially transparent (between 20% and 80% when defining transparency as 100% and opacity as 0%). Display the artificial artifacts and natural features on one screen, and display the artificial features and natural features of the electronic drawing on one screen, respectively, on one screen, or on two separate screens. You may. Alternatively, the screen can be displayed by using the above two methods through three separate screens. At this time, the error or difference between the artificial feature and the natural topography is displayed in a different color or shade, such as red, so that the user can search for the artifact and natural topography showing the error or difference to the user more quickly and conveniently. Make sure

Next, the matching unit 150 in the digital map generating terminal 100 is previously stored in the attribute information and the storage unit 180 received from an external server through the communication interface 110 using coordinates of artificial features and natural terrain. The attribute information of the corresponding artificial feature and the natural topography is matched, and the attribute information is displayed on the display unit 160 at the position of the artificial feature and the natural topography together with the artificial feature and the natural topography (S1200).

At this time, the attribute information displayed on the display unit 160, when the display unit 160 is composed of two separate screens, the attribute information received from an external server is displayed on the corresponding artificial feature and natural terrain on one screen. On the other screen, the attribute information pre-stored in the storage unit 180 is displayed on the artificial feature and the natural top, and the attribute information of the artificial feature and the natural topography is displayed on each of the two screens. In the case where the screen 190 is composed of three separate screens, the respective property information is displayed on two screens as described above, and the other screen indicates an error or difference between the property information displayed on the two screens. The attribute information is detected through the error compensator 182 in the controller 180 to display only the attribute information representing the detected error or difference. In addition, when the display unit 160 is configured as one screen, the attribute information received from the external server through the error compensator 182 in the controller 180 is compared with the attribute information previously stored in the storage unit. In the case of attribute information, only one attribute information of the two attribute information is displayed on the display unit 160. When an error or difference is detected, the attribute information indicating the detected error or difference is displayed both up and down of the screen. In addition, the attribute information in which the error or difference is detected is displayed in a different color or shade such as red color, so that the attribute value representing the error or difference can be searched more quickly and conveniently to the user.

 As such, those of ordinary skill in the technical field of the present invention may have various embodiments in the method of displaying the attribute information through the display unit 160 within the scope of the technical idea of the present invention. It includes various embodiments that fall within the technical scope.

Subsequently, the numerical map maker searches for attribute information of the artificial feature and the natural terrain received from the external server displayed on the display unit 160 and attribute information of the artificial feature and the natural terrain previously stored in the storage unit, and is preferably formed on the screen. By applying a touch method (of course, input using a mouse or an external input means) through the touch screen, the error (when the size and width of the building / road, etc. are different) and differences (building / road) If there is a back light or not, etc.), change it by using Add / Delete / Modify using touch fan. Then, the artificial features stored in the attribute information DB 194 of the storage unit 190 based on the addition / deletion / modification contents of the attribute information of the artificial feature and the natural feature input through the editing unit 184 in the controller 180 and The content of the attribute information for each natural terrain is edited and stored as changes, and the changed information is stored in the change information DB 198 in the storage 190 (S1300).

As described above, when the correction of the artificial features and natural topography, which are incorrectly depicted in the electronic drawing, and the speed information of each artificial feature and the natural topography is completed (S1400), the correction is completed and stored in the digital map generation terminal 100. The electronic drawing stored in the unit 190 is transmitted to the system server 200 through the communication interface 110 to the wired / wireless communication network (S1500).

Accordingly, the system server 200 changes the attribute information marked by hand in the drawing during the field survey, which is the in-situ editing process (S30 of FIG. 1) in the conventional digital map generating method, to the drawing created first through the computerization work. The process of modifying and supplementing the results of drawing and map input by displaying information and attribution data can be omitted.

 Therefore, the system server 200 constructs the terrain and features in geometrical form based on the completed electronic drawing received from the digital map generating terminal 100, and sets the required object as a model of point, line, plane and network area division or the same. Based on the point, line, and surface morphology defined by the National Geographic Information Institute as a combined geometric model, structured editing is performed directly to display and edit the artificial and natural topography manually by computerization (S1600). At this time, in the structured editing, the attribute data displayed in the drawing is edited in a hidden state (not stored on the screen).

When the structured editing is completed as described above, a digital map is produced and printed using a software program provided by the National Geographic Information Institute and provided to the National Geographic Information Institute requesting the digital map production (S1700).
