Description

Numerical map production system of road infrastructure through GIS and reference point location information verification {DIGITAL MAP PRODUCTION SYSTEM OF ROAD INFRASTRUCTURE BY CONFIRMING GIS AND REFERENCE POINT LOCATION INFORMATION}

The present invention relates to a numerical map production system, and more particularly, to a numerical map production system for road infrastructure through GIS and reference point location information confirmation.

In general, a numerical map refers to a map that expresses the geographical and topographical contents to be expressed numerically. have. In other words, the numerical map is applied to the illustrated image while expressing the geographical/topographical characteristics of a specific point as numerical information.

The numerical map construction process is completed through several processes as follows. First, a paper map is digitized or scanned to form a numerical map, and then various input errors are corrected.

Then, after transforming into an actual coordinate system to meet the user's purpose through coordinate transformation, a topological structure is established for understanding mutual location and correlation between spatial objects. Thereafter, the attribute data related to each figure data is input to the numerical map that has undergone the establishment of the topological structure.

At this time, the above-described attribute data includes various identifier information. As an example, a Unique Feature Identifier (UFID) is used as an identifier for a feature on the numerical map of the National Geographic Information Service. It refers to an identifier uniquely assigned to a feature as a single identifier indicating the location information, management agency, and other attribute information to be assigned. It is used as an identifier for linking with other geographic information or cross-referencing between features for retrieval and utilization.

Numerical maps produced in this way enable faster and more accurate map search than paper maps, and are superior in information management and usability to support various planning and decision-making more effectively.

Numerical map should be accurately applied to the illustrated image of the digitized geographical information of the point so that the user can easily obtain geographical and geographical information while looking at the map, and the illustrated image should also be accurately shown in accordance with the geographic information.

Such geographic information may be a GPS coordinate value or a coordinate value according to the administrative district unit of the cadastral map. do. Hereinafter, numerical information such as GPS coordinates, coordinate values of cadastral maps, and various data measured/collected at actual points will be collectively referred to as geographic information.

However, since the drawings generated by the conventional digital mapping system are input by reading aerial photos, satellite images, and images acquired through vehicles, it is difficult to ensure the accuracy of the features of the drawings, and, accordingly, There is also a problem that it is difficult to guarantee the accuracy of the attribute data.

For this reason, in order to ensure the accuracy of the numerical map, the numerical map makers are producing a more accurate numerical map through the process of the numerical map generating method described in FIG. 1 .

1 is a flow chart for explaining a conventional general numerical map production process.

As shown, the numerical map maker prints on paper a drawing created through digitizing or scanning such as a survey map, aerial photograph, satellite image, and roadside image obtained through an MMS vehicle (S10), and the corresponding area of the printed drawing to perform a field survey (S20).

Here, in the above-mentioned field survey, whether various artificial features and natural topography such as buildings, roads (paved, unpaved), railways, parks, rivers, mountains, rice fields, fields, etc. Check directly whether the size, direction, and shape of the artificial features and natural terrain located in the actual location are accurately indicated on the drawing, and if there are other parts, manually correct the drawing.

In addition, attribute data such as the name, name, and basic information (number of floors of a building, width of a road or river, etc.) of the corresponding artificial and natural features are manually written in the corresponding positions of the drawings.

In this way, when the representation of the artificial features and natural topography incorrectly described in the drawing and the attribute data of each artificial feature and natural topography is completed through the field survey, the change information and the change information and By displaying attribute data and correcting and supplementing the drawing and map input performance, in-place editing is performed to determine the geographical correlation between topography and features (S30).

Then, the topography and features edited through the in-place editing are configured in a geometric form, and the necessary objects are points, lines, planes, and network domain division models or a geometric model that combines them as defined by the National Geographic Information Service. Structural editing is performed by manually displaying and editing corresponding artificial features and natural topography based on morphology (S40). At this time, in the above-described structured editing, the attribute data displayed in the drawing is edited in a hidden (stored without being displayed on the screen) state.

When structured editing is completed in this way, a numerical map is produced and printed using a software program provided by the National Geographic Information Service, and the numerical map is produced/requested (S50). At this time, the software program is a program for changing the structured and edited drawing into a defined form, and it is usually used as it is with a known program provided by the National Geographic Information Service.

On the other hand, for road infrastructure, it is necessary to check the exact location and standard, and to include the location information collected in this way in the numerical topographic map. In order to effectively manage road infrastructure, facility management systems such as road management systems and pavement management systems are being developed and operated.

However, in order to use it as data for life cycle cost analysis, it is necessary to establish a DB for detailed items. In addition, based on the DB constructed in this way, the above-mentioned numerical topographic map is also required to be easily searched and analyzed visually.

Furthermore, since the corresponding facilities of the facility information data stored in the DB are discarded and reconstructed and installed after a certain period of time has elapsed, the facility information data must be periodically updated. Therefore, such data update technology is urgently required.

It includes a GIS server 200 that can update the existing numerical map.

The GIS server 200 includes a facility DB 210 for storing information data on road infrastructure, a numerical topographic DB 220 for storing data on a numerical topographic map, and a data collection module for receiving facility data ( 230) and the facility data received from the data collection module 230 and the information data of the facility DB 210 to confirm the update target information data, and to search the corresponding map data in the numerical topography DB 220 A confirmation module 240, an update processing module 250 for updating the information data and map data to be updated, and a reporting module 260 for automatically generating and outputting a list of road infrastructure related to the updated information data ) and a map module 270 for editing and outputting a map image corresponding to the update process of the update processing module 250 . Here, the map image is drawn based on a digital topographic image.

It is a topographic image and a diagram showing the same, and FIG. 5 is a numerical topographic image showing an enlarged portion 'A' of FIG.

S10; Data collection steps

The data collection module 230 of this embodiment collects road infrastructure related facility data.

As described above, the data collection module 230 collects facility data from the correction computer 100, a government office system that manages road infrastructure, and a digital topographic map management institution system that produces or manages a digital topographic map, and in addition to the road The system of an institution that manages information on infrastructure may vary.

The data collection module 230 of the present embodiment periodically accesses the DB, and collects the data version when the DB facility data is updated and the data version is changed.

For reference, since the facility data on road infrastructure is relatively large, the relevant institution creates and manages road infrastructure related information by region. Therefore, the data collection module 230 checks the version of each divided data, and extracts and collects only the data of the region where the version is changed.

In this embodiment, the data collection module 230 is formed along the edge of the 'Buheunggyo' and the new record of 'Buheunggyo' in 'Bukancheon' located in 'Bukan-myeon, Yeongcheon-si, Gyeongsangbuk-do' from the government office system that manages road infrastructure. The records of the maintenance work on the shoulders 1, 2, 3, and 4 (refer to Fig. 5) connected to the 'Buheung Bridge' are collected as the facility data with the updated data version, and the road pavement construction for vehicle passage to the 'Buheung Bridge' is collected. Records are also collected as facility data. The new road here is part of 'Banjeong 2-gil'.

In addition, the data collection module 230 provides information about the 'Buheunggyo' area and 'Banjeong 2-gil' in 'Bukancheon' located in 'Bukan-myeon, Yeongcheon-si, Gyeongsangbuk-do' from the digital topographic map management institution system that produces or manages the numerical topographic map. The first digital topographic image is collected as facility data as shown in the drawing (a) of FIG. 4 and FIG. 5 . Here, FIG. 5 is an enlarged view of 'A' shown in FIG. 4(a). In this implementation, the road infrastructure to be updated is a 'Banjeong Bridge' bridge, and the paved road for smooth vehicle passage to the 'Banjeong Bridge' is a part of the 'Banjeong 2-gil' road. The newly paved road section has been expanded.

For reference, the data collection module 230, as shown in the figure (b) of FIG. 4, only the rectangular range within a certain distance (d) from the 'Banjeong 2-gil' road image, which is the facility data to be checked, the first numerical value Extracted as a topographic image.

In this implementation, the road of 'Banjeong 2-gil' is road infrastructure, and the 3 endpoints (P1, P2, P3) of the 'Banjeong 2-gil' image determine the range of a certain distance (d) for extracting the first digital topographic image. However, if the road infrastructure is a tunnel, bridge, or other type of facility, the criterion for determining the range of a certain distance (d) may not be the endpoint of the road infrastructure image.

Therefore, the criterion for determining the range of a certain distance d is the outermost point of the road infrastructure image regardless of the type of road infrastructure. Subsequently, the data collection module 230 checks the GPS information of the first digital topographic image extracted from the corresponding information system. To this end, the data collection module 230 checks the actual location of the point corresponding to each vertex of the extracted first digital topographic image, and checks the GPS information of the actual location.

For reference, in the road infrastructure of this implementation, 'Banjeong 2-gil', the endpoints of 'P1, P2' are connected to the main road, and the endpoint of 'P3' passes through the Buheung Bridge of Bukancheon and passes through the Gyeongbu Expressway. It is an administrative road leading to the 'reconstruction site (not city)'.

It is an image showing how the confirmation module converts the numerical topographic image of the information data to understand the road condition, and FIG. 8 is a view showing the state in which the light and dark image of FIG.

S20; Information data search step

The update target confirmation module 240 of this embodiment checks the facility data received from the data collection module 230 , and searches the corresponding information data in the facility DB 210 and the numerical topography DB 220 .

As described above, since the facility data is divided by region, the update target confirmation module 240 searches the facility DB 210 and the numerical topography DB 220 with reference to the corresponding area of the facility data.

In this embodiment, the update target confirmation module 240 checks the state information of the road infrastructure included in the update target information data in the facility DB 210 . The road infrastructure to be updated in this implementation is 'Buheung Bridge' and 'Banjeong 2-gil' roads, and additionally 'Shoulders 1, 2, 3, 4' formed along 'Bukancheon'.

In addition, in this embodiment, the update target confirmation module 240 searches for and confirms the second digital topographic image (refer to FIG. 6 ) in which the original image of the road infrastructure included in the update target map data is the map data from the digital topographic DB 220 . do. Here, the update target confirmation module 240 checks the GPS information of the first digital topographic image received from the data collection module 230, and searches the corresponding second digital topographic image in the digital topographic DB 220 based on this. .

On the other hand, the cadastral edit map image (refer to FIG. 9) drawn on the basis of the second digital topographic image is searched for in the digital topographic DB 220 and confirmed. For reference, the second digital topographic image is an aerial photographed image of the new construction of 'Buheung Bridge'. A pair of temporary bridges (G) were installed for the passage of 'Bukancheon'. On the other hand, 'Shoulders 1, 2, 3, 4' constitute unpaved roads, and 'Banjeong 2-gil' roads are 'Banjeong 2-gil (1st road)' and 'Banjeong 2-gil (2nd road)' connected to 'Daegyeong-ro'. )' is partially packaged.

As described above, in order to check the road condition, the update target confirmation module 240 of this embodiment processes the second digital topographic image, which is the map data retrieved from the digital topographic DB 220 for raw image analysis, so that the road and the road It divides the non-paved road and further divides the paved road and the unpaved road.

To explain this in more detail, the update target confirmation module 240 processes the second numerical topographic image shown in FIG. 6 so that the brightness can be checked for each color, and converts it into the light and dark image shown in FIG. 7 . Subsequently, the update target confirmation module 240 checks the lightness and darkness in various parts of the contrast image, and considers the brightness within the reference value range the same brightness, and determines the same brightness range as the same section as shown in FIG. 8 to generate a section image. .

Here, the update target confirmation module 240 divides the level of brightness into a paved road and an unpaved road. In this embodiment, the update target confirmation module 240 considers a section having a brightness of '35' or less as a pavement, based on the relative value divided into '0 ~ 100' according to the brightness, and sets the brightness exceeding '35'. The section is considered as unpaved road and classified.

The parts identified as roads in the section image of this implementation are Daegyeong-ro, Banjeong 2-gil (No. 1 road), shoulder road 1, 2, 3, 4, Buheung Bridge (foundation), temporary bridge (G), Banjeong 2-gil (2nd road). Road) 1, 2, Gyeongbu Expressway, among which the paved roads (solid line) are Daegyeong-ro, Banjeong 2-gil (1st road), Banjeong 2-gil (2nd road) 1, Gyeongbu Expressway, and unpaved roads (virtual lines) are Line) is shoulder road 1, 2, 3, 4, temporary bridge (G), and Banjeong 2-gil (2nd road) 2.

Meanwhile, among paved roads, sections with a brightness of '20' or less are regarded as newly paved roads and classified. In this implementation, Banjeong 2-gil (1st road) and Banjeong 2-gil (2nd road) 1 are newly paved roads compared to other paved roads.

As described above, the update target confirmation module 240 of this embodiment searches the information data corresponding to the facility data collected by the data collection module 230 in the facility DB 210 and the numerical topography DB 220, respectively, The update target confirmation module 240 analyzes the second numerical topographic image of the map data based on the update target road infrastructure.

In this implementation, the road infrastructure to be updated is the 'Buheung Bridge' bridge, and the road newly built for smooth vehicle passage to the 'Banjeong 2-gil' is a part of the 'Banjeong 2-gil', so the second numerical topographic image analysis It is performed based on the standard, and the second numerical topographic image analysis is performed based on the brightness.

It is a drawing showing the updated state of the map image and the photographed image of the actual point.

S30; Data update processing steps

The update processing module 250 of the present embodiment updates information data corresponding to the facility data to the facility data. In this implementation, a unique code is set for each road infrastructure in the facility data, and a unique code belonging to the specific information belonging to the road infrastructure is also set. If it is not retrieved from the information data, the relevant road infrastructure is a new construction that did not exist before, and if the unique code is retrieved from the information data, the information data is updated with the facility data.

For example, the unique code of 'Buheung Bridge' included in the facility data is 'KN-04031-B004', and the name, location, and specifications that are specific information of 'Buheung Bridge' are 'KN-04031-B004-NA', respectively. , 'KN-04031-B004-PO', and 'KN-04031-B004-SI'.

And, 'revival bridge' and its name, location, and specifications included in the information data are the same as the unique code of the facility data, respectively. Accordingly, the update processing module 250 updates the information data according to the unique code. For reference, the update processing module 250 collectively updates the information data according to the facility data regardless of the difference between the facility data and the information data.

In addition, the unique code of the 'Banjeong 2-gil' road is 'KN-04031-R093', and the name, location, and specifications of the 'Banjeong 2-gil' road are 'KN-04031-R093-NA', 'KN', respectively. -04031-R093-PO', 'KN-04031-R093-SI'.

In addition, the unique code of the 'Shoulder' road is 'KN-04031-R8101', and the name, location, and specifications of the 'Shoulder' road are 'KN-04031-R8101-NA' and 'KN-04031-R8101', respectively. -PO', 'KN-04031-R8101-SI'.

For reference, 'Shoulder 1', 'Shoulder 3', and 'Shoulder 4' among 'Shoulders' are new roads, so the corresponding unique codes exist only in the facility data and are not included in the information data. Accordingly, the update processing module 250 adds the corresponding facility data to the information data.

Subsequently, the update processing module 250 updates the map image of the numerical topographic DB 220 based on the information data and the corresponding cadastral edit image.

To explain this in more detail, in the information data of the facility DB 210, a unique code is set for each road infrastructure, and in particular, when the road infrastructure is a road, a plurality of roads are connected to each other. The specific information of the road also includes a unique code for another road connected to the road.

Accordingly, the update processing module 250 updates the map image based on the corresponding unique code of the information data and the cadastral edit image. For reference, since the cadastral compilation map shows the divided zones, the update processing module 250 can track the location of the new road by keeping an eye on it.

The update processing module 250 of the present embodiment checks the update points 1 to 4, which are new roads, in the information data, and the update processing module 250 divides the new roads of the update points 1 to 4 in the cadastral compilation map. It is independent of the designated zone and is determined by the location connected to the connecting road.

Therefore, the road at the update point 1 is determined as the shortest course that does not violate '1147 street', '1139 street', '1145 2nd street' and 1146 division 1', and the road at the update point 2 is connected to the connecting road confirmed in the information data. As it continues, it is decided as the shortest course that does not infringe on '1145 1 Jeon' and '1144 Street'.

For reference, since the road at the update point 2 is connected to other roads in addition to the connection road, it is extended via the connection road. In this way, the road at the update point 3 and the update point 4 is determined based on the information data and the cadastral edit map image, respectively.

The update processing module 250 additionally updates the new road identified in this way by showing it in the existing map image as shown in FIG. For reference, the added roads 'extended road', 'Shoulder 1', 'Shoulder 2', and 'Shoulder 4' were marked in black for identification, but the color (white) of the road displayed on the existing map image is the same. so you can update it.

The update processing module 250 stores and updates the updated map image as map data in the numerical topography DB 220 .

S40; Steps to create a list of updates

The reporting module 260 of this embodiment provides the facility data to be updated collected by the data collection module 230 and the information data retrieved by the update target confirmation module 240 from the facility DB 210 and the numerical topography DB 220 . It is output to each designated terminal so that the operator can check it.

In addition, the reporting module 260 executes an approval request so that the operator checks the facility data and information data output to the terminal and selects whether to proceed with the subsequent process, and the operator clicks the output button to input an approval or re-search input signal. , according to this, the facility DB 210 and the numerical topography DB 220 may be searched again, or the update processing of the update processing module 250 may be continued.

The control spring 724 is coupled between the stop 723 and the inner surface of the rotating case 711 . The control spring 724 provides an elastic force to push the control rod 722 and the stopper 723 to the left.

The prevention part 725 may be inserted into the prevention groove 721a formed on the side of the control case 721 . When the control rod 722 is moved to the left, the prevention part 725 is inserted into the prevention groove 721a, and when the control rod 722 is moved to the right, the prevention part 725 is separated from the prevention groove 721a. do.

The outer surface of the prevention part 725 and the inner surface of the prevention groove 721a are formed in a sawtooth shape. When the prevention part 725 is inserted into the prevention groove 721a, the control rod 722 and the stop part 723 cannot rotate the shaft and move up and down, and thus the fixed state of the rotation rod 712 is fixed. You can keep it more robust.

The control moving part 726 is coupled to the left end of the prevention part 725 and has a triangular cross section. The control moving case 727 is coupled to the side of the control case 721 and the control moving part 726 is inserted so as to be movable left and right.

When the user holds the control handle 728 and applies a downward force, the lower end of the control handle 728 comes into contact with the upper surface of the control moving unit 726 and pushes the control moving unit 726. Accordingly, the control moving unit 726 is shifted to the right.

As the control moving part 726 is moved to the right, the prevention part 725 is separated from the prevention groove 721a, and the control rod 722 overcomes the elastic force of the control spring 724 and is moved to the right.

As the control rod 722 is moved to the right, the stopping part 723 is also separated from the stopping groove 712a, and the rotating rod 712 and the camera 110 coupled thereto are of the stopping part 723. It can be rotated horizontally freely without restrictions.

When the horizontal rotation of the camera 110 in a direction desired by the user is finished, the user releases the control handle 728 , and the control rod 722 moves to the left according to the elastic force of the control spring 724 .

When the control rod 722 moves to the left, the stop 723 is inserted into the stop groove 712a to limit horizontal rotation of the rotary rod 712 . At this time, the prevention part 725 is inserted into the prevention groove 721a, and the control moving part 726 moves to the left to lift the control handle 728 upward.
