Description

Technical Field [1] The present invention relates to a digital map management system for a polygon unit,

The present invention relates to a polygon-based numerical map management for a general-purpose editing process of a digital map in which polygon general property information is automatically generated in a numerical map managed by a polygon unit, ≪ / RTI >

Generally, when a geometric element is expressed in a digital map, spatial data is represented using points, lines, and plan elements. Specifically, in the case of expressing a surface in a digital map, various features such as a road boundary, a building, a vernacular river, and a terrain boundary are represented as a surface and displayed in a color and a pattern. In other words, most of the surface objects are represented by one surface object, but two or more surface objects are required to represent a single feature object.

In most systems that currently edit or manage a digital map, a polygon object is represented by a polygonal object. If another surface exists in the interior of the surface, the inner surface object is called a hole. Also, forming multiple polygons to form one object is called multi polygon. In this case, when a polygon is expressed in color, a hole does not display a color. That is, it represents a perforated surface.

When performing input and editing operations for producing a digital map (DWG file) using the above-described method, polygons and polygons can be represented only by closed-polylines connected to both ends.

At this time, the polygon object and the polygon object do not exist. For example, when a polygon with one hole is represented, another closed polyline may be displayed in the closed polyline area, and a polygon having two planes may be separated into individual closed polylines.

However, since a single feature can be represented by several objects, it is necessary to input and edit the digital map, or to consider other objects related to the search for a feature in the digital map, And the efficiency of the work is lowered.

Also, in the case of a hole polygon, the color is not completely filled when the color is displayed, but the hole inside the hole is not displayed and the hole should be expressed.

However, in the conventional hole display method, two closed polylines, that is, an outer polyline and an inner polyline are overlapped to cover an inner polyline (hole), or two polylines are selected, It can not be expressed as an object.

Additional work is required to retain the object type when importing or exporting data formats for other systems that support polygons or polygons. In other words, when importing, it is necessary to separately manage the information of the separated objects and to edit the objects separated from the system of the stored file at the time of exporting.

On the other hand, a numerical map can be confirmed using an AutoCAD system. However, when using a CAD system of a higher version, polygons and polygon objects exist. However, when using the AutoCAD system, It is impossible to check and compatibility problems occur.

However, if an object created through another application program is stored as a file, it is impossible to edit or modify the object without having an application program corresponding thereto.

In order to achieve this, conventionally, a polygon generation system using the attribute information of a digital map object and a method thereof (Registration No. 10-0759269) ", which is used to input unique attribute information for each polygon, Was invented.

However, since the conventional technique requires the operator to directly input corresponding attribute information for each polygon in accordance with a set rule, it is troublesome and difficult to work. More specifically, in the conventional invention, in a numerical map in which regions or objects are divided in units of polygons, a polygon in which a plurality of polygons constitute one object and a polygon in which one polygon constitutes one object And inputs attribute information to each of the polygons thus divided.

However, since this attribute information input method requires a manual input of attribute information for a large number of polygons, the work burden is large. Further, since the polygon needs to input attribute information for each polygon, time burden is also large. There has been a problem that false attribute information may be input to an arbitrary polygon due to a mistake or a mistake.

As a result, the conventional invention has a problem in that the object structure of the polygon can only be limitedly utilized in a simple numerical map.

The present invention uses the above-mentioned prior-art patent No. 0759269 as it is. Therefore, the features of the device configuration described below are all those described in Patent No. 0759269.

However, the present invention is applicable to a polygon in which one polygon constitutes one object in the numerical map, or a generation module unit which automatically identifies a polygon in which a plurality of polygons constitute a single object, among the configurations disclosed in the above-mentioned Japanese Patent No. 0759269 20, an attribute information setting module 30 for automatically inputting attribute information corresponding to the polygon, and an attribute information attaching module 40 for attaching the attribute information to the polygon, Thereby constituting a constitutional characteristic.

Therefore, the device configuration, characteristics and operation relationship described below are partially cited in the above-mentioned Japanese Patent No. 0759269, and the configuration related to the main features of the present invention will be described in detail at the rear end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The system of the present invention performs the function of assigning certain attribute information to a polyline belonging to a polygon as illustrated in FIG. 1, and receives a numerical map produced by an operator using the digital map production software (A) A generation module unit 20 for generating an MPolygon object by analyzing a geometric relationship of a polyline constituted by the polygon selected by the operator on the numerical map, An attribution information attaching module 40 for linking the set attribute information to the polyline, and a retrieval extracting module 40 for retrieving the MPolygon existing in the digital map. A change module 60 for removing or linking attribute information linked to the polyline in the digital map, A display module unit 80 for displaying an MPolygon extracted through the search and retrieval module unit 50 using a screen or an output device provided separately for an operator to confirm the MPolygon, A polygon object, and a polyline object, and an object comparison module 100 for comparing the digital map and the target terrain image with each other, 20, 30, 40, 50, 60, 70, 80, and 80 in accordance with the procedure of the operation program so that the polygon can be searched, And a control module 90 for controlling the control modules 90, 100, and 110.

In the present embodiment, the processing of the digital map is performed by the digital mapping software (A), and the description thereof will be omitted below. However, It is desirable to understand that the function is included. That is, the digital map stored in the DWG file is received and can be confirmed by using an AutoCAD.

Here, the digital map production software (A) is set to auto CAD, but the present invention is not limited thereto.

When the polling module 22 selects a polyline on the digital map using the object selection module 21, the verification module 22 determines whether the polylines are closed or not, , The intersection of the polylines or the existence of independent polylines in the polyline, and then, through the object creation module 23, one polygon or multiple polygons (MultiPolygon) as an MPolygon object. Here, if it is confirmed that two or more polygons share one polyline, the two or more polygons are considered to be polygons, and the two or more polygons are managed as one MPolygon object.

On the other hand, if the polyline is not closed or crossing occurs, the confirmation analysis module 22 ignores the polyline because it can not form a polygon, and if there is an independent polyline in the polyline, it is judged as a corresponding HOLE do. For reference, a polygon is one in which a plurality of polygons constitute one object. In other words, if the number of polygons in the MPolygon object is one, it becomes a polygon object, and if more than one polygon is a polyolgon object. As a result, the MPolygon object is a single polygon or polygon processed as a single object, allowing more efficient management of the polygon.

The generation module unit 20 according to the present invention will be described in more detail.

The object selection module 21 of the generation module 20 checks the polyline shown in the numerical map, and the confirmation analysis module 22 determines whether the polylines are closed, whether two or more polygons share one polygon 4 (a block diagram showing a configuration of the attribute information module unit according to the present invention) and FIG. 5 (a block diagram showing the configuration of the attribute information module unit according to the present invention) by confirming whether or not the other polyline intersects with another polyline, In which the control module unit according to the present invention scans the digital map, sets the attribute information in the attribute information setting module, and links the attribute information to the polygon in the attribute information attaching module). Then, the MPolygon object And stores it in the database module unit 70 as object data.

The scan module 31 of the attribute information setting module 30 scans the digital map recognized by the generation module 20 and the polygon position confirmation module 32 reads the MPolygon objects 101, 102, 103, 104, 105 ). The attribute information setting module 33 of the attribute information setting module 30 configures an attribute information table including MID, PID, and HOLE to set attribute information linked to each polyline. Herein, MID represents an intrinsic value for distinguishing MPolygon in a digital map, PID represents a serial number of polygons belonging to a polygon, HOLE represents a value indicating whether the polygon belongs to a hole If the value of the hole is 1, it means that it is a Hole object. If the value of the hole is 0, it means that the object is a boundary (boundary line as a strict meaning specified in a map or a drawing).

The process of automatically setting the attribute information in the digital map by the attribute information setting module 30 according to the present invention will be described in more detail. The scan module 31 of the attribute information setting module 30, Proceeding at least one of the longitudinal scanning 111 and the lateral scanning 112. In the embodiment of the present invention, the automatic setting of attribute information by the longitudinal scanning 111 will be described by way of example.

4, the scan module 31 of the attribute information setting module 30 performs a longitudinal scan 111 on the digital map output to the display module 70, Check them in order. Next, the polygon position determination module 32 identifies the positions of the MPolygon object and the constituent polygons of the detected polyline, and the attribute information setting module 33 sets attribute information of the polygon in the order . More specifically, the scan module 31 of the attribute information setting module 30 sequentially detects the polylines while proceeding to the longitudinal scanning 111, and the polygon positioning module 32 detects the poly Line, and the attribute information setting module 33 sets the MID of the MPolygon object to which the polyline belongs to '1'. Since the polyline is detected first in the MPolygon object, the polyline is set to '1', which is a target polygon identification code of the polyline, and whether the polygon is a hole is checked. If the polygon is a hole, the HOLE is set to '1' And set it to '0' if it is not HOLE. As a result, the attribute information setting module 33 automatically sets the attribute information of the polygon to (1,1,0).

Subsequently, the polygon position confirmation module 32 regards the polyline newly sensed by the scan module 31 as the next polygon, and the attribute information setting module 33 sets the attribute information of the polygon in accordance with the above- (1,2,0), and the next polygon is automatically set to (1,3,0). In this process, attribute information is automatically set continuously until all the polylines are detected. In the first MPolygon object 101, six polylines are detected and attribute information is automatically set to the corresponding polygons.

Next, when all polygon property information of the first MPolygon object 101 is set, the second MPolygon object 102 is checked and MID is set to '2'. For reference, since the second MPolygon object 102 is composed of one polygon, the property information of the second MPolygon object 102 is automatically set to (2,1,0).

Next, the third (103), fourth (104), and fifth MPolygon objects (105) are located on similar height lines. However, even if a plurality of MPolygon objects 103, 104, and 105 are overlapped on a similar height line, the attribute information setting module unit 30 regards the connected polylines as one MPolygon object, And sets the PID by considering the polygon formed by the connected polylines as one MPolygon object. Therefore, even if a polyline configured in the fourth MPolygon object 104 is detected first in the longitudinal scanning 111 process than a polyline configured in the third MPolygon object 103, Is combined with one MPolygon object to set property information, and the constituent polyline of the fourth MPolygon object 104 sets new property information independently and in parallel. As a result, the property information of the third MPolygon object 103 is automatically set to (3, n, n) irrespective of the position of the fourth MPolygon object 104, and the fourth MPolygon object 104 is set to (4, n, n), the attribute information is automatically set.

On the other hand, the fourth MPolygon object 104 has a hole-type polygon, and therefore the attribute information to be automatically set is (4,1,0) and (4,1,1). Of course, the fifth MPolygon object 105 is located between the polygons whose property information is (4,1,0) and (4,1,1) in the fourth MPolygon object 104, Attribute information is automatically set to (5, 1, 0) irrespective of the MPolygon object 104.

As described above, the attribute information setting module unit 30 scans the digital map to check the position order of the MPolygon object, and combines the thus-confirmed position sequence with the MPolygon object information confirmed by the generation module unit 20, The attribute information is automatically set and stored in the database module unit 70.

If two or more MPolygon objects on the same position are detected in the longitudinal scanning 111 as in the above embodiment, the MPolygon objects are scanned in the horizontal direction (112) Setting.

The attribution information attaching module 40 links the set attribute information to the polyline as shown in Fig. 2B. Specifically, the attribute information (MID, PID, HOLE) is constructed to link the attribute information to a polyline constituting each polygon. This is because, if the user selects a polygon in the digital map and forms a polygon, the polygon composes the attribute information and links the attribute information to each polygon.

On the other hand, when the user selects the polygon in the digital map, the attribute information (MID, PID, HOLE) is constructed as described above and the attribute information is linked to each polyline. At this time, the polyline may include a hole.

In addition, the search and extraction module 50 searches for a polyline on a numerical map, generates a polygon corresponding thereto, extracts a polyline in the polygon, registers the processed object as a boundary object when the HOLE is 0 , And registers the processing object as a Hole object when the HOLE is 1, thereby storing and managing the attribute information of the MPolygon object.

Here, the MPolygon object stored in the database module unit 70 may be edited or otherwise stored and managed.

The change module 60 converts the polygon into a closed polyline by adding, removing, or removing all attribute information of the MPolygon to the MPolygon. Specifically, the modification module unit 60 regards the polylines belonging to the previously registered MPolygon and the polylines selected by the user for addition, together with the geometric relation using the confirmation analysis module 22, A partial adding module 51 for adding a polygon to the MPolygon as shown in FIG. 2C by restructuring the attribute information by attaching the attribute information to the polygon, and a polygon selected by the operator in the MPolygon as shown in FIG. A partial deletion module 52 for deleting a part, and a release module 53 for removing attribute information attached to all polylines belonging to the pre-registered MPolygon as shown in FIG. 2E. At this time, the release module 53 preferably removes the pre-registered MPolygon object from the database module unit 70.

The object comparison module 100 compares the terrain image of the object type, such as the completed MPolygon object, the polygon object, the polyline object, etc., with the terrain image that is the object of the polygon object, according to the above-described procedure Reference). For this, the object comparison module unit 100 searches the database module unit 70 for the target terrain image of the digital map completed by the polygon technology, and searches the terrain image of the digital terrain image and the digital map by numerical coordinates In conclusion, Fig. 7 allows an object modification module according to the present invention to be identified in the same manner as shown in the image of the preparation of the position of the ground-based image on the basis of the terrain image.

As a result of the comparison in the present embodiment, it is confirmed that the position of the first ground-water image is displaced from the first position on the basis of the first terrain image.

The object modification module 110 confirms this and, as shown in FIGS. 7 and 8 (an image showing how the object modification module according to the present invention modifies a ground image in accordance with the terrain image), the first ground object Moving the image to the first terrain image updates the terrain image of the object type, such as MPolygon object, polygon object, polyline object, and so on.

FIG. 9 is a view showing a state in which the object comparison module according to the present invention performs a plane and side confirmation of the terrain image, FIG. 10 is a view showing the center of the plane and the center of the side of the terrain image tracked by the object comparison module And FIG. 11 is a diagram sequentially showing a process of the object modification module moving the ground image according to the center of the image of the corresponding geographical image.

The object comparison module module 100 according to the present embodiment includes a color analysis module 101 for analyzing the color of each pixel of the terrain image to distinguish the plane and the side of the terrain image, Further comprising a position tracking module (102) for identifying the plane boundary lines (L1, L3) and the side boundary lines (L2, L4) Moves the position of the plane boundary lines L1 and L3 based on the image center position information tracked by the position tracking module 102 and outputs the position of the ground water image, which is a polyline of the corresponding topographic image, And is corrected in accordance with the plane boundary lines L1 ', L3'.

More specifically, the color analysis module 101 determines the planar range of the terrain images St1 and St2 by checking the colors of the terrain images St1 and St2 in pixel units, Thereby generating plane boundary lines (L1, L3) of the closed section.

Next, the color analysis module 101 checks the hues around the above-mentioned plane area in units of pixels, and creates a side border line (for example, L2 and L4 are confirmed, the space between the side boundary lines L2 and L4 and the planar boundary lines L1 and L3 is determined as the side range of the corresponding topographic images St1 and St2.

When the plane and sides of the terrain images St1 and St2 are identified according to the process of the color analysis module 101, the location tracking module 102 detects the image of the planar boundary lines L1 and L3, Calculate the center and confirm it. Wherein the image center is the center of gravity of the planar boundary lines (L1, L3). 11 (a), the position tracking module 102 calculates and determines the image center of the ground water image, which is a polyline of the terrain images St1 and St2, , St2).

When the plane boundary lines L1 and L3 and the image center of the ground image are determined, the position tracking module 102 determines the straight line distance between the plane boundary lines L1 and L3 and the side boundary lines L2 and L4, And the topographic images St1 and St2 in which the planar boundary lines L1 and L3 and the side boundary lines L2 and L4 are arranged in the same straight line direction are classified into one set. It is to be noted that the straight line distance and linear direction confirmation between the plane boundary lines L1 and L3 and the side boundary lines L2 and L4 are not limited to the shape of the plane boundary lines L1 and L3 (See L1 'and L2'). After the center of the image of the completed figure is determined, the straight line distance to the center of the image of the plane boundary lines L1 and L3 and the straight line distance .

The object modification module 110 calculates an average of linear distances between the plane boundary lines L1 and L3 and the side boundary lines L2 and L4 of the terrain images St1 and St2 classified into one set, The plane boundary lines L1 and L3 of all of the terrain images St1 and St2 are shifted by the average value in the straight line direction as shown in Fig. 11 (c). The positions of the shifted planar boundary lines L1 'and L3' are finally determined to be the actual positions of the corresponding topographic images St1 and St2, and the object modification module 110 updates the center of the image of the ground- And corrects the position in accordance with the image center of the plane boundary lines (L1 ', L3'). The object modification module 110 may move all the plane boundary lines L1 and L3 of all the topographic images St1 and St2 one by one. The planar boundary lines L1 and L3 of the terrain images St1 and St2 constituting one set as described above are moved together by the average value to increase the processing speed and reduce the burden.

After the operator completes the numerical map draft of the object type, it is not necessary to individually check whether or not the position of the ground image is correct, and the image combination of the object comparison module unit 100 and the modification of the object modification module unit 110 So that it is possible to efficiently and precisely check and correct errors.

2F, the control module 90 includes a data input module 10, a generating module 20, an attribute information setting module 30, an attribute information attaching module 40, By controlling the module unit 50, the modification module unit 60, the database module unit 70, the display module unit 80, the object comparison module unit 100, and the object modification module unit 110, And generates a polygon using attribute information.

Hereinafter, a method of generating attribute information of a digital map object through the system having the above-described configuration will be described with reference to FIGS. 3A and 3B.

First, the control module 90 receives a numerical map produced in the form of another file format (SHP, NGI, etc.) from the operator as shown in FIG. 3A (S2). In the present embodiment, the resin drawing is set to receive from the outside, but the present invention is not limited to this, and work can be performed even when only the execution screen (DWG surface) is executed.

Next, the control module unit 90 assigns attribute information to the polyline (S4). That is, referring to FIG. 3B, the control module 90 newly generates a unique id value (S4a). Where id is a unique value for identifying a polygon or a polygon.

Next, in order to process the polygon object or the polygon object constituting the digital map, the control module 90 initializes the PID to 'count = 0' (S4b). Here, count can be understood as representing the number of polygon objects or polygon objects constituting the numerical map.

First, the control module unit 90 links attribute information to a boundary polyline in the MPolygon object (S4c). Specifically, the control module 90 searches polygons in the MPolygon object on the digital map (S4c1), and generates attribute information (MID, PID, HOLE) according to the polygon (S4c2). In this case, the count is preferably automatically set to 'count + 1', and the counting order of the polygons is sequentially set according to the scanning order of the property information setting module 30 as described above.

The control module 90 sets the attribute information value of the extracted polygon to 'MID = id, PID = count, HOLE = 0' (S4c3), and links the set property information to the boundary polyline in MPolygon .

The control module 90 searches the polygon in the MPolygon on the digital map (S4d1), and generates attribute information (MID, PID, HOLE) according to the polyline (S4d2).

The control module 90 sets the attribute information value of the extracted Hole polyline to 'MID = id, PID = count, HOLE = 1' (S4d3) Link.

Next, the control module 90 searches the MPolygon object linked with the attribute information in the digital map, and then selects the processed object (S6). At this time, the control module 90 checks the attribute information (MID, PID, HOLE) linked to the processed object (S8). The control module 90 determines whether MPolygon among the objects stored in the database module 70 is searched using 'MID' among the attribute information (S10).

In step S10, when the MPolygon is searched, the control module 90 determines whether a polygon is searched in MPolygon using 'PID' (S12).

In step S12, when the polygon is searched, the control module 90 determines whether 'HOLE = 1' (S14). That is, if it is determined in step S14 that 'HOLE = 1', the control module 90 registers the processing object as a Hole object in the searched polygon (S16).

Next, the control module 90 registers polygons in the MPolygon (S18). That is, in case of a newly created new polygon, a polygon is registered in MPolygon. At this time, the control module 90 sets the MPolygon unique key to 'MID' (S20). Next, the control module unit 90 registers MPolygon in the database module unit 70 (S22). This is registered in the database module unit 70 in the case of newly created MPolygon. Finally, the control module unit 90 registers and manages a new MPolygon including the new polygon and the new polygon in the database module unit 70.

On the other hand, if it is determined in step S14 that 'HOLE = 0', the control module 90 registers the processing object as a boundary object in the searched polygon (S24). If the polygon is not found in step S12, the control module 90 generates a new polygon (S26).

In step S10, if MPolygon is not searched, the control module 90 generates a new MPolygon (S28).
