Description

[0001] The present invention relates to a digital map error checking system,

The present invention relates to a digital map error checking system according to a change in terrain shape of a ground, and more particularly, to a digital map error checking system in which a ground water image represented by a polygon object type is precisely compared with a real terrain image located at a corresponding point, The present invention relates to a digital map error checking system in accordance with an improved terrestrial terrain change so as to adjust the numerical coordinates of the corresponding points or adjust the terrestrial water image to the numerical coordinate positions.

Generally, to represent a surface water image expressed in a digital map as a geometric element, points, lines, and facets of the surface are utilized.

Specifically, in the case of expressing a surface in a digital map, various features such as a road boundary, a building, a broad 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, when displaying a color, the hole is not displayed but the hole is not displayed.

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.

In addition, additional operations are required to retain the object type when importing or exporting data formats of other systems that support polygons or polygons.

In other words, when importing, it is necessary to separately manage the information of the separated object, and the object separated from the system of the stored file at the time of exporting must be edited into a single object again.

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 and modify the object without having an application program therefor.

A polygon generation system using attribute information of a digital map object and a patent technique for the polygon generation system have been disclosed, in which unique attribute information such as numerical coordinates is input for each polygon, and polygons are automatically identified based on the attribute information have.

However, since this technique requires the operator to directly input corresponding attribute information for each polygon in accordance with a set rule, the work is troublesome and difficult.

To describe this in more detail, conventionally, in a numerical map in which regions or objects are classified 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 Directly inputting the numerical coordinates of the corresponding point to each of the polygons thus classified, or inputting the inherent code linked with the numerical coordinates as attribute information.

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.

Moreover, this manual method has a problem in that it causes positional discrepancy between the actual terrain image (aerial shot image) of the aerial photographing point and the corresponding ground image in the digital map, making it difficult to produce a precise digital map.

In addition, there has been a problem that the object structure of the polygon can not be utilized in a simple numerical map.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 1, the system of the present invention performs a function of assigning certain attribute information to a polyline belonging to a polygon. In this system, a numerical map produced by an operator using a digital map production software (A) (20) for generating an MPolygon object by analyzing a geometrical relationship of a polyline constituted by the polygon selected by a worker on a numeric map, a polygon object generating unit An attribute information setting module 30 for setting the value of the attribute information linked to the line, an attribute information attaching module 40 for linking the set attribute information to the polyline, and an MPolygon A change module unit 60 for removing attribute information linked to the polyline or maintaining the link state in the numerical map, and an MPolygon object A display module 70 for displaying an MPolygon extracted through the search and extracting module 50 by using a screen or an output device provided separately so that an operator can confirm the extracted MPolygon, An object comparison module 100 for comparing the digital map with the object map data of object types such as an MPolygon object, a polygon object, and a polyline object, and a target terrain image, An object modifying module 110 for modifying an object having a difference in position according to the terrain image, and an object modifying module 110 for modifying the object 10, 20, and 20 in accordance with a procedure of the operation program so that a polygon can be searched, 30, 40, 50, 60, 70, 80, 100, 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 regarded as a polygon, 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 an MPolygon object is one, it becomes a polygon object, and if more than one polygon is a polygon object, a polygon object becomes a polygon object.

As a result, the MPolygon object is a single polygon or a multi-polygon processed as a single object, thereby enabling 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, The control module module according to the present invention scans the digital map, the attribute information setting module attaches the attribute information, and the attribute information attachment module links the attribute information to the corresponding polygon) And the MPolygon object in the database module unit 70 as object data of the MPolygon object.

The scan module 31 of the attribute information setting module 30 scans the numerical map recognized by the generation module 20 and the polygon position confirmation module 32 reads the MPolygon objects 101, , 104, and 105 are confirmed.

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 eigenvalue for distinguishing MPolygon in a digital map, PID represents a serial number of polygons belonging to a polygon, HOLE represents a hole (hole) for an individual polyline belonging to a polygon 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 confirms the position of the polygon object and the constituent polygons of the detected polygon, and the attribute information setting module 33 determines the position of the polygon Set attribute information in 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 in the object data, 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 the object polygon identification code of the polyline, and it is checked whether the polygon is a hole, 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, and the first polygon (MPolygon) object 101 detects 6 polylines 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 to set the MID to '2'.

Since the second MPolygon object 102 is composed of one polygon, the attribute 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 First, it detects the polygon belonging to the same MID, and sets the PID by considering the polygon formed by the connected polylines as one MPolygon object.

Therefore, even if the polyline configured in the fourth MPolygon object 104 is detected first in the longitudinal scanning 111 process than the polyline configured in the third MPolygon object 103, The constituent polylines of the MPolygon object 103 are combined with one MPolygon object to set property information and the constituent polylines of the fourth MPolygon object 104 are set in parallel Set new attribute information independently.

As a result, the property information of the third MPolygon object 103 is automatically set to (3, n, n) regardless of the position of the fourth MPolygon object 104, and the fourth emolgon MPolygon) object 104 is automatically set to (4, n, n).

On the other hand, the fourth MPolygon object 104 is equipped with 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 may be inserted between the polygons whose property information is (4,1,0) and (4,1,1) in the fourth MPolygon object 104 Position, the property information is automatically set to (5, 1, 0) irrespective of the fourth MPolygon object 104 as described above.

As described above, the attribute information setting module unit 30 scans the digital map to check the positional order of the MPolygon object, and checks the position sequence thus confirmed and the MPolygon ) Object information to automatically set attribute information for each polygon, and stores the attribute information in the database module unit 70. [

Meanwhile, when two or more MPolygon objects on the same position line of the longitudinal scanning 111 are detected as in the above-described embodiment, the MPolygon objects are scanned in the horizontal direction (112) The attribute information is automatically set in the detection order.

The attribute information attaching module 40 links the set attribute information to the polyline as shown in FIG. 2B. Specifically, the attribute information attaching module 40 composes the attribute information (MID, PID, HOLE) Link attribute information to the line.

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 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 in a different format.

The change module 60 converts the polygon into a closed polyline by adding, removing, or removing all attribute information of the polygon to the polygon (MPolygon).

Specifically, the change module unit 60 considers the geometric relationships between the polylines belonging to the already-registered MPolygon and the polylines selected by the user for addition, together with the analysis module 22, A partial adding module 51 for adding a polygon to the MPolygon as shown in FIG. 2C by reconstructing the attribution information by the module unit 30 and attaching it to the polyline, A partial removal module 52 for partially removing the polygon selected by the operator from the pre-registered MPolygon, and attribute information attached to all polylines belonging to the already registered polygon MPolygon as shown in FIG. (Not shown).

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, and the polyline object, and the terrain image, which is the object of the polygon object, according to the above- do.

To this end, the object comparison module 100 searches the database module 70 for the target terrain image of the digital map completed by the polygon technology, and displays the terrain image and the terrain image of the digital map on the basis of the numerical coordinates, (The object comparison module according to the present invention compares the terrain image of the object type, such as an MPolygon object, a polygon object, and a polyline object, with the terrain image).

As a result of the comparison, it is confirmed that the position of the second ground image is displaced from the second position with reference to the second terrain image.

The object modification module 110 confirms this and displays the image of FIG. 7 (an image showing a state in which the object modification module according to the present invention prepares to modify the position of the ground image on the basis of the terrain image) and FIG. 8 The modification module modifies the ground image in accordance with the terrain image), the second ground image is moved in accordance with the second terrain image so that the MPolygon object, the polygon object , A polyline object, and the like.

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) 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 90 links the attribute information to the boundary polyline in the MPolygon object (S4c). Specifically, the control module 90 adds the polygon in the MPolygon object After searching (S4c1), attribute information (MID, PID, HOLE) according to the polygon is generated (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 sets the attribute information to the boundary poly Link to the line.

The control module 90 searches the HOLE polyline 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 on 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 an MPolygon among the objects stored in the database module 70 is searched using 'MID' in the attribute information (S10).

In step S10, when the MPolygon is searched, the control module 90 determines whether a polygon is searched for in the 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 unit 90 registers the polygon in the MPolygon (S18). That is, if the new polygon is newly generated, the polygon is registered in the MPolygon. At this time, the control module 90 sets the unique key of the MPolygon to 'MID' (S20).

Next, the control module unit 90 registers the MPolygon in the database module unit 70 (S22). This is registered in the database module unit 70 in the case of the newly generated MPolygon.

Finally, the control module unit 90 registers and manages a new polygon (MPolygon) including a new polygon and a 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 the MPolygon is not found, the control module 90 generates a new MPolygon (S28).

In addition, the data input module 10, the generation module 20, the attribute information setting module 30, the attribute information attachment module 40, and the search extraction module 50, which constitute the system according to the present invention, ), The modification module unit 60, the database module unit 70, the display module unit 80, the control module unit 90, the object comparison module unit 100, and the object modification module unit 110, And is mounted in the form of a server rack inside the housing 200 as shown in FIG.

At this time, the housing 200 is a housing having a human key size, such as a data center.

An entrance door 210 is provided on the front surface of the housing 200 so that the operator can access the entrance door 210 for maintenance, and ventilation units 300 are installed on both sides.

In addition, a temperature sensor 220 is installed on the inner ceiling of the housing 200 and a control board 230 is installed on one side of the housing 200 to detect the temperature of the temperature sensor 220 The control board 230 controls the driving of the ventilation unit 300 so that the ventilation unit 300 can be opened and closed.

Here, the reason why the ventilation unit 300 is required is that since a large number of modules mounted in the housing 200 in the form of a server rack have a high processing speed, a large amount of heat is generated, and therefore, Therefore, in the present invention, natural cooling through natural ventilation is performed to prevent deterioration in advance, thereby contributing to achieve longevity.

9 to 11, the ventilation unit 300 includes a pair of left and right side frames 310, an upper frame 320 connecting upper ends of the side frames 310, And a lower frame 350 connecting the lower ends of the lower frame 310, and has a rectangular frame shape.
