Description

Digital map production system capable of updating digital maps through comparison of new topographical information and existing topographical information

The present invention relates to a digital map production system, and more particularly, to a digital map production system capable of updating a digital map through comparison of new topographical information and existing topographical information.

A digital map means a digital map produced by analyzing and numerically editing various topographical data obtained from survey 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 drawing in the form of a digital map is created by digitizing or scanning a paper map, and the created drawing is converted into an actual coordinate system to suit the user's purpose through coordinate conversion.

Then, attribute data is input into the numerical map in which the topological structure is established to determine the mutual location and correlation between spatial objects. At this time, the attribute data includes various identifier information, and as an example, a unique feature identifier (UFID) is used as an identifier for a feature of a digital map of the National Geographic Information Institute, which is assigned to the feature It is a single identifier representing location information, management agency, and other attribute information, which is uniquely assigned to a feature. It is composed of agency code, map number, feature identification code, serial number field, etc. For utilization, it is used as an identifier for linkage with other geographical information or cross-reference between geographical features.

However, since the generated drawings are input through the reading of aerial photographs and satellite images, it is difficult to guarantee the accuracy of the features of the drawings, and accordingly, it is difficult to guarantee the accuracy of attribute data given to each feature.

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

Referring to FIG. 1, a digital map maker prints a drawing generated through digitizing or scanning, such as a survey map, aerial photograph, or satellite image, on paper (S10), and prints the corresponding region of the printed drawing. Conduct a site survey (S20).

At this time, in the field survey, whether various artificial features and natural terrains such as buildings, roads (paved, unpaved), railways, parks, rivers, mountains, rice fields, fields, etc. actually exist, or actual places Check directly whether the size, direction, and shape of artificial features and natural features located in the map are accurately displayed on the drawing, and if there are any other parts, manually correct them on the drawing.

In addition, attribute data such as trade name, name, and basic information (number of floors of a building, width of a road or river, etc.) of the artificial landmark and natural terrain are manually marked at the corresponding location on the drawing.

In this way, when the artificial features and natural features incorrectly depicted on the drawings and the property data of each artificial features and natural features are completed through the field survey, the change information is displayed on the drawings initially generated through computerization using the indicated drawings. And by displaying the attribute data, correcting and supplementing the results of drawing and map input, in-place editing is performed to grasp the geographical correlation of topography and features (S30).

Then, the topography and features edited through the in-place editing are constructed in a geometric form, and the necessary object is a model of point, line, plane, and network area division, or a geometric model that combines them, which is the point, line, and plane shape defined by the National Geographic Information Institute. Structural editing is performed to manually display and edit corresponding artificial features and natural features individually through computerization based on the image (S40). At this time, in the structured editing, the attribute data displayed on the drawing is edited in a state of being hidden (stored without being displayed on the screen).

When the structural editing is completed in this way, 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, which has requested digital map production (S50). At this time, the software program is a program that changes the structured and edited diagram into a defined form, and a known program generally provided by the National Geographic Information Institute is used as it is.

However, in the conventional digital map production method, the provision of aerial images must be provided, and aerial images are collected only through aerial photography. It had to be done in cycles.

In contrast, changes in topography and artificial structures occur from time to time regardless of the above cycle, so the error rate for digital maps of the drawing image type inevitably increases as the distance from the date of production of the digital map increases. There is a problem that causes great inconvenience in using the digital map.

Another purpose is to provide a system.

2 is a block diagram showing the overall configuration of a digital map production system capable of updating a digital map through comparison of new topographical information and existing topographical information according to an embodiment of the present invention.

As shown, the digital map production system according to the present invention generates a drawing image based on an aerial photographed image, and a digital map production apparatus 100 for producing and updating a digital map based thereon, the aerial photographic image and the digital map. It includes a storage device 200 for storing each and a ground measuring device 300 installed at a point where a new insertion image is inserted to obtain topographical information.

The storage device 200 includes a captured image DB 210 for storing aerial images, and a digital map and drawing image of a captured image type completed by applying geographic information and numerical information after editing or drawing the aerial photographed images. It includes a numerical map DB 220 for storing each type of numerical map.

The numerical map production device 100 includes an input/output means 121, an auxiliary output means 122, and a calculation means 110, and the calculation means 110 includes a processing module 111, an interlocking module 112, and numerical values. It includes a module 113, an editing module 114 and a correction module 115.

The input/output unit 121 can be operated in a touch screen manner, and the auxiliary output unit 122 can output a reference image for a region to be corrected. The input/output unit 121 may be applied with touch screen technology to a slim type display such as LCD or PDP, and the auxiliary output unit 122 may be applied with a slim type display such as LCD or PDP.

The processing module 111 may communicate with the storage device 200 and execute a task menu related to image processing. When an input signal is generated by manipulating the input/output unit 121, the processing module 111 processes the input signal to generate an output signal for outputting an image corresponding to the input/output unit 121 and the auxiliary output unit 122. deliver each

The interlocking module 112 performs a function of matching position coordinate values and magnification so that the output positions of the digital map images output to the input/output means 121 and the auxiliary output means 122 can match.

The numerical module 113 performs a function of completing and producing a digital map by inputting geographic information and numerical information to be linked to the corresponding location of the drawing image output to the input/output means 121, respectively.

The editing module 114 searches for images stored in the storage device 200, outputs them to the input/output means 121 or auxiliary output means 122, and edits the image according to the input signal input from the input/output means 121. perform the function of

The correction module 115 may perform a function of automatically correcting interference by checking whether an inserted image inserted into a drawing image type digital map image output to the input/output unit 121 is interfered with.

The operator manipulates the digital map production device 100 according to the present invention to complete a drawing image based on the aerial photographed image output to the input/output means 121 and the auxiliary output means 122, and numerical values based on these drawing images. In order to produce a map, a digital map is completed by inputting topographic information and numerical information to the drawing image drawn in the input/output means 121, and the completed digital map is finally stored in the storage device 200.

3 is an exemplary view sequentially illustrating the production of a digital map using a digital map production system according to an embodiment of the present invention.

The digital map production device 100 can produce both a digital map of a photographed image type and a digital map of a drawing image type. exemplify

A worker searches for captured images in the captured image DB 210 and proceeds to produce a digital map of the type of captured image while editing them.

To explain this in more detail, the operator selects a 'digital map production menu' from among the work menus presented by the processing module 111 . The processing module 111 presents 'photographed image type digital map production' and 'drawing image type digital map production' menus as submenus of the digital map production menu, and the operator selects 'photographed image type digital map production' menus. ' Select the menu.

The editing module 114 proceeds with a normal search procedure for aerial photographed images to be edited, and equally adjusts the magnification of a plurality of aerial photographic images of the same region that are searched in this way and output to the input/output means 121. After that, editing is performed to connect them into one to complete the unified aerial photographic image data that becomes the background of the digital map of the photographed image type.

Since the digital map production apparatus 100 adjusts a plurality of aerial images having various magnifications to the same magnification and then connects and edits them, a detailed description thereof is omitted here.

The numerical module 113 inserts the corresponding topographic information and numerical information into the aerial photographed image for the digital map background thus completed. Here, topographical information relates to place names, building names, etc. of each part of an aerial photographic image, and numerical information relates to GPS coordinate information.

In general, the numerical module 113 first synthesizes GPS coordinate information based on a reference point in an aerial photographed image for a digital map background, and inserts topographical information according to the GPS coordinate information to complete a digital map.

The digital map of the photographed image type thus completed is stored in the digital map DB 220.

Meanwhile, the operator may attempt to create or update a digital map of a drawing image type based on a previously produced digital map of a photographed image type. To this end, among the corresponding menus presented by the processing module 111, 'create a digital map of a drawing image type' or 'renew a digital map of a drawing image type' is selected.

When the operator selects the menu 'Create digital map of drawing image type', the editing module 114 guides the operator to input the numerical information of the area to be output in order to search the digital map image, and the operator follows the guidance to the numerical value of the digital map. Enter your information.

The editing module 114 retrieves a digital map of a photographed image type from the digital map DB 220 based on the numerical information and outputs the digital map to the input/output unit 121 and the auxiliary output unit 122, respectively.

FIG. 3(a) shows a numerical map of captured image types output to the input/output unit 121 and the auxiliary output unit 122, respectively. For reference, the input/output means 121 and the auxiliary output through the interlocking module 112, which is a device that matches the position coordinate values so that the output positions of the digital map images output to the input/output means 121 and the auxiliary output means 122 coincide. The output state of the digital map image output to the means 122 is always synchronized.

To explain this in more detail, when the operator adjusts the output magnification or position by manipulating the captured image type digital map image being output through the input/output means 121, the interlocking module 112 converts the input/output means 121 and input/output means 121 when the operator adjusts the position of the digital map image output to the input/output means 121 by checking the output magnification and numerical information on the position coordinate values of the digital map image output to the auxiliary output means 122, respectively. Adjust to be synchronized so that both the position and output appearance of the digital map image output to the auxiliary output means 122 can be matched.

Eventually, when the operator moves or adjusts the magnification of the digital map image output to the input/output means 121, the digital map image output to the auxiliary output means 122 is also moved to the same length by the operation of the linkage module 112. or the scale is adjusted.

Subsequently, the operator completes the drawing image as shown in FIG. 3(b) by performing drawing work based on the photographed image of the digital map output to the input/output means 121. For drawing, the input/output unit 121 can open or close the currently outputted captured image while maintaining the drawing image, and while opening or closing the captured image, the auxiliary output unit 122 can open or close the currently outputting captured image. It maintains the photographed image so that the worker can refer to it in drawing work.

When the drawing image is completed, according to the operation of the operator, the numerical module 113 stores topographic information and numerical information so that they are linked to the corresponding location of the drawing image, respectively, and as shown in FIG. 3(c), the numerical map of the drawing image type finalize with

4 is an exemplary view showing partial correction of a digital map using a digital map production system according to an embodiment of the present invention.

The operator may attempt to update the digital map of the drawing image type, and for this, selects the 'update digital map of the drawing image type' menu from the corresponding menus presented by the processing module 111.

When an operator selects a corresponding menu, the editing module 114 guides inputting numerical information of a region to be output to search for a digital map image, and the operator inputs numerical information of the digital map according to the corresponding guidance.

The editing module 114 retrieves a numerical map of a drawing image type from the numerical map DB 220 based on the input numerical information and outputs it to the input/output unit 121. For reference, in this embodiment, the digital map of the drawing image type shown in FIG. 3(c) can be output through the input/output means 121.

Meanwhile, a reference image for a region to be corrected may be output to the auxiliary output unit 122 . As shown in FIG. 4(a), the reference image may be a newly photographed aerial image, a photographed image of a region to be corrected directly from the ground, or a bird's eye view or blueprint of a structure to be corrected.

In other words, if a new structure is built or destroyed in an arbitrary ground area after the digital map is produced, the existing digital map image can be corrected by referring to the reference image in order to update it.

It is preferable that such a reference image is a digital map of a relatively new version of an aerial image or a photographed image type compared to a digital map of a drawing image type to be corrected, and a digital map of a drawing image type to be corrected output to the input/output means 121. It is preferable that the output states of the reference image output to the auxiliary output means 122 are synchronized by the linkage module 112 .

In this case, there is an effect of maximizing the digital map update efficiency because only the part to be updated needs to be partially corrected without the need to entirely rewrite the production of the digital map of the drawing image type.

The operator compares the drawing image type digital map image output to the input/output means 121 and the reference image output to the auxiliary output means 122 and checks differences such as new construction of a new structure.

In this embodiment, the A1 and B1 areas, which are the corresponding regions of the reference image that are different from the digital map image, were identified. A1 and B1 are areas where a new building has been constructed, and a building image is drawn and inserted at the location corresponding to A1 and B1 based on the digital map image of the drawing image type in the input/output means 121 of the touch screen type. .

As shown in FIG. 4(b), the editing module 114 outputs the inserted images A2 and B2 inserted by the operator in the digital map of the drawing image type, and the numerical module 113 outputs the inserted images A2 and B2. By applying and inserting the topographic information and numerical information corresponding to B2), information such as 'Seocho 1-dong Community Service Center' and 'Volvo' can be output.

In this way, the digital map production apparatus 100 according to the present invention, when correction is requested due to a partial change in the digital map of the drawing image type that has been produced, easily corrects the corresponding part without correcting the entire digital map. There is an effect that can be searched and corrected.

5 is an exemplary view showing how to correct an inserted image of a digital map using a digital map production system according to an embodiment of the present invention;

Since the operator additionally inserts an image based on the digital map of the type of drawing image output to the input/output means 121, there is a limit to precise drawing, and interference with the existing drawing image cannot be ruled out.

That is, as shown in FIG. 5(a), some of the inserted images A2 and B2 may interfere with the lines L1 and L2 of the existing drawing image, thereby degrading the completeness of the digital map.

Of course, it is possible to use the digital map in which the existing drawing image and the inserted images (A2, B2) interfere with each other, but in this case, the problematic inserted image (A2) is different from the actual target structure in its shape. Actual users of the corresponding digital map inevitably experience difficulties in using the digital map.

In order to solve this problem, the digital map production apparatus 100 configured in the digital map updating system according to the present invention further includes a correction module 115 for correcting the inserted images A2 and B2.

The correction module 115 searches for the inserted images (A2, B2) inserted by the operator within the digital map of the drawing image type, and selects the existing lines (L1, L2) in the existing digital map among the inserted images (A2, B2). It is checked whether there are inserted images (A2, B2) intersecting with .

The correction module 115 searches for the inserted image A2 intersecting the existing lines L1 and L2, and generates new sides T1 and T2 of the inserted image A2 intersecting the existing lines L1 and L2. Check.

Subsequently, the correction module 115 checks the region where the inserted image A2 is located. As mentioned above, if the inserted image A2 is properly inserted without interference with the existing drawing image, it will be located within this area, but if interference with the existing drawing image occurs, the inserted image A2 invades the neighboring area. .

However, since the operator will mainly insert the insertion image A2 in the viewing area even if interference with the existing drawing image occurs, the correction module 115 checks the area occupied by the insertion image A2 and determines the area occupied by the relatively wide viewing area. regarded as

The correction module 115 checks the viewing area of the inserted image A2 and checks whether the vertexes of the new sides T1 and T2 are located within the viewing area. In this embodiment, the correction module 115 confirmed that the vertex P of the first new side T1 among the new sides T1 and T2 is located within the present area.

The correction module 115 starts with the vertex P so that the new side T1 at which the vertex P is located in this area is aligned with the existing line L1 intersected, and draws the corrected side T1' in the view area. ) to be modified.

On the other hand, the new side (T2) whose vertex is located in the neighboring area is drawn to match the extension line (AX) of the line parallel to the existing line (L2) in the neighboring structure image (C), and is finally modified as the corrected side (T2'). do.

Eventually, the inserted image (A2) is updated to a more precise and reliable digital map while being corrected with the corrected image (A3) having the corrected edges (T1', T2'), and through this, the user using the digital map has higher reliability. It is possible to use the numerical map.

6 is a diagram showing an overall appearance of a ground measuring device according to an embodiment of the present invention.

As described above, the present invention can quickly correct an inserted image inserted by an operator into a correction image in a drawing image type digital map using the correction module 115.

However, when a newly built structure is a very important structure as a landmark of the region, takes a different shape than the usual rectangular shape, or requires additional confirmation, correction using the correction module 115 alone may not be enough. can
