Description

A network-based guide system for locative information and a method

The present invention relates to a location information guidance system and a location information guidance method based on a network.

More specifically, building maps are created by accumulating and arranging the building data generated by photographs so that they exist in the same location as the current location with respect to a predetermined location, and the created map is viewed on a user's own browser connected to the network. The present invention relates to a location information guide system and a location information guidance method for providing a user with additional information corresponding to a building existing on the map.

When a person needs to go to a place, most people use an atlas to review the distance from the current location to the point they want to go to, the transportation to get to that place, or the road conditions when using a vehicle. do.

At this time, the above-described atlas is displayed with the name of the area divided by the road, and the names and buildings existing for each of the above-mentioned areas are displayed. It is indicated by means.

In other words, by displaying the unique name 'Haengju Sanseong' on the map, which is calculated and accumulated geographically along with the display means such as '∴', the viewer can see that Haengju Sanseong is a scenic spot and at the same time Make sure you know the location of the acid.

The above-described map concept on the ground has been expanded to the map concept provided on a web page due to the development of computer systems and data communication networks.

That is, users using a computer system connect to a server that provides map information before going to any place or building, and enter a place name or building information to search through a page provided from the connected server as a search word. Map information for informing the location of the area or building the user is looking for is output on the screen.

However, the above-described map concept could not provide any other information to the user other than a map concept that simply informs the user of the location of the area or the building to be searched for.

Therefore, it was difficult for the user to find a building that he or she wanted to find, it was difficult for the user to find a specific building, and it was difficult to check whether the building was correct, and it was not easy to read the map. It was hard to know.

In addition, information providers, building owners, and shop owners can express the details of buildings, stores, etc. that are expressed through the network, so that they want to approach users more easily and be strongly recognized. there was.

An object of the present invention is to build a map by accumulating and arranging the building data generated by the photo to exist in the same position with respect to the current position to solve the above-mentioned problems, and to produce the map The present invention provides a location information guide system and a location information guide method for providing a user with a view on a browser connected to a network and providing additional information corresponding to the user's selection of a building existing on the map.

1 is a view for explaining a location information guide system based on a network according to the present invention.

As shown, the main server computer receives the location search information input by the user through the data communication network 300 connecting the unspecified client computers 100 and the main server computer 200 and the data communication network 300 described above. Client computer 100 outputting to 200 and the main server computer 200 for providing the map information to the client computer 100 in response to the location search information input through the above-described data communication network (300).

In particular, when the user selects a predetermined location on the map output on the screen of the client computer 100, the main server computer 200 may provide information about the map centered on the location of the client computer 100. And additional information stored using the location information provided by the client computer 100 and the screen output information included in the client computer 100 to be output on the screen of the client computer 100 described above. Let's do it.

Of course, the main server computer 200 may provide a menu to the client computer 100 to partially enlarge or reduce the location selected by the user so that the user can use it.

The above-mentioned additional information includes the name of the building, the name of the office or the mall existing in the building categorized by each floor, and the telephone number corresponding to the selection of the office or the mall from the information provided primarily. Secondary provisions are provided, including industry and size. In addition to the above-described information, the system administrator may implement various items. The additional information provides various information that can be displayed about a building, a mall, an office, etc. according to a user's request, and may provide advertisements for the corresponding building, the mall, an office, etc. according to a user's selection.

Referring to the configuration of the main server computer 200 having the above-described function as a block diagram having a schematic concept with reference to Figure 2, the database unit 210 having at least one additional information and the system administrator An operating program for upgrading the above-described database unit 210 with data inputted by the user, and outputting the data stored in the above-described database unit 210 according to the location search information input from the user of the client computer 100. A communication controller 230 which receives the data input unit 220 and the location search information transmitted from the client computer 100 as described above, and outputs map information input from the controller 240 and additional information thereof; The map information is provided in response to the location search information input through the communication controller 230 described above, and is input through the communication controller 230. The control unit 240 reads the additional information corresponding to the location information and the screen output information in the database from the above-described database unit 210 and transmits the additional information to the client computer 100 through the above-described communication controller 230. It is composed of

In this case, the location information and the screen output information analyzed by the control unit 240 of the main server computer 200 will be briefly described. For the location information, the user selects a predetermined position on the screen using an input means such as a mouse (click). In this case, X and Y coordinate values thereof mean the screen output information. When the control unit 240 reads the map data from the database unit 210, it means the above-mentioned index information of the map data.

Next, the operation of the location information guide system based on the network according to the present invention configured as described above will be described in detail.

First, when a system administrator uses a main server computer 200 to easily designate a predetermined location and provide map information centered on the location, the system manager transmits the above-described map information to the user. You need to build a base.

In the above-described data construction method, as shown in FIG. 3, a location such as a subway entrance is selected by using a camera, and a distance of a building is photographed based on the location. At this time, the photographing is performed so that each building is well represented.

The captured image data is output to the main server computer 200, and only building data is extracted by a predetermined application program (S310). In the extracted building data, buildings, shops, offices, etc. are finally made with the user in mind.

The extracted building data is reset based on a predetermined location, and the building data is disposed at the set location to generate one map information (S320), and the generated map information is displayed on the screen output information and building data. By storing the location information and the additional information on the building (S330), all the database construction process is performed.

As described above, when the database is built on the main server computer 200, the user connects to the main server computer 200 and inputs predetermined location search information such as a subway station to receive desired map information on the screen. The map can be displayed.

That is, as shown in FIG. 4, a user of the client computer 100 executes a web browser, inputs a domain name of the main server computer 200 described above, and executes the main server computer 200 described above. Proceed with the communication connection (S410).

The control unit 240 of the main server computer 200 has a communication connection outputs the initial menu screen to the client computer 100 via the communication control unit 230 to display on the screen (S420).

In this case, the initial menu screen may have various menus and advertisements including a menu for selecting or inputting a predetermined position by the user.

If the user selects a search button after inputting location search information for designating a predetermined location through the initial menu screen as described above (S430), the controller 240 stores the map information generated based on the selected location. Read from the base unit 210 and transmits to the above-described client computer 100 through the communication control unit 230, the client computer 100 displays it on the screen (S440).

That is, when the user inputs the alternate band as the location search information, as shown in FIG. 5, the controller 240 reads the map information having the alternate band exit from the database unit 210 as a reference position, and controls the communication controller ( 230 to output to the client computer 100 so that the map is displayed on the screen.

At this time, all image data displayed on the map is output in the same state as the actual building.

On the other hand, when the user selects a certain point through the input means such as a mouse on the screen to display the map as shown in Figure 5 on the screen, the location information of the point selected by the input means through the communication control unit 230 It is transmitted to the control unit 240 (S450).

In addition, the controller 240 searches for the database unit 210 by using the input position information and the screen output information of the controller 240 (S460).

As a result of the search, the stored additional information corresponding to the position information and the screen output information is read and transmitted to the client computer 100 through the communication control unit 230 and output on the screen (S470).

That is, when a user selects a predetermined building on the map shown in FIGS. 5A and 5B, the user is occupied if the office building is not only detailed information on whether the building is an office-oriented building or a commercial building. From the business name to the office, you can provide information that tells you what the office is doing.

In addition, in the case of a mall building (especially a department store), the user can provide information on the types of stores in the mall, as well as product information such as the type and price of the goods provided by each store. You can easily learn about the area without having to walk around and observe it.

On the other hand, the present invention includes the URL in the above-described additional information, the client computer 100 when one of the buildings included on the map is selected, and a predetermined office or store operating the homepage is selected from the buildings. This can be implemented so that the user can inquire more information by directly connecting to the corresponding homepage.

Referring again to the map shown in Figures 5a and 5b as follows.

First, a user selects a desired area or selects a specific building in a map by using an input means such as a mouse or a keyboard or directly touching a touch screen.

Once the area is displayed at the request of the user, the map image for the specific area is provided and the magnification is adjustable. The user can move the map in that state and select a specific building, mall, or office. This is because the above-described buildings, stores or offices are represented on the map. In this case, the provider should make a request from the user who wishes to disclose his / her building, store, etc. through a map such as a landlord, a mall owner, or an office owner, and the name of each building and a signboard for the user's convenience. do.

When the user selects a specific building, detailed additional information about the building is provided, and an advertisement for the building or the store may be provided to the user at the request of the landlord or the store owner who resides in the building. At this time, the advertisement is provided within a range that does not make the user feel uncomfortable using the map information.

The same applies to the case where the user selects a specific mall, office, or the like, and the provided map basically allows the user to conveniently obtain information, and in addition, various additional information is provided.

Of course, it is possible to install a banner advertisement on the map according to the setting of the information provider, it can provide an advertisement to the user. However, as described above, this is possible within the scope of not impairing the user's convenience.

In addition, as shown on the outside of the map shown in Figures 5a and 5b, the user can easily find a specific building, and the information is divided horizontally and vertically for various reasons such that the computer can easily recognize the point requested by the user. Indicates. In FIG. 5A and FIG. 5B, numbers are displayed on the horizontal side, that is, east-west direction, and are displayed in English on the vertical side, that is, north-south direction.

The present invention basically provides a user with a map image including a picture of a building or the like. Therefore, in the map image provided to the user, a sign indicating each building may also be displayed. In addition, upon request, an advertisement representing a building, etc., which is not actual, may be inserted to be displayed in the same manner as a signboard.

6A to 6C are detailed flowcharts illustrating an embodiment of a map information generating process according to the present invention.

In the location information guidance system and location information guidance method based on the network according to the present invention, a process of generating building data to be represented by a map and displaying it as map information is included. This will be described in detail with reference to FIGS. 6A to 6C.

6A is a diagram illustrating a flow of a building data generation process.

Building data generation is based on the photographing made on the building, and selects the photographs to be included in the map from the photographed photographs (s601), scans the selected photographs (s602), and corrects the scanned and photographed data. Newly created based on the photo (s603). The building data thus obtained is stored in the database (s604).

This will be described in detail below.

The biggest problem with building photography is the size and distance of the building. To solve this problem, it is common to use a 4 * 5 disc camera.

The 4 * 5 disc camera allows you to modify the structure of the building and get high resolution photos. However, the 4 * 5 disc camera has a disadvantage in that it is difficult to move and store and fix the equipment, and consumes a lot of time. In addition, the film is a sheet film (sheet film) has a lot of problems when shooting a lot of cost and a large amount.

To overcome this problem, the camera uses 135m and 120m cameras because the economic loss is greater than the economic benefits of using a 4 * 5 disc camera that can swing or tilt to correct the building's curvature.

In order to solve the problem of moving, storing and fixing the 4 * 5 disc camera, the extended working area can be secured through 135m and 120m cameras that are easy to move, carry and store. In addition, it is possible to use a roll film rather than a sheet film in terms of use of the film, and thus a lot of cost savings can be obtained.

Films can use Kodak 100sw, Kodak 100vs and Push Films. These are all films with high resolution as slide films. The Kodak 100sw, for example, has the warm tones of the film, so shooting in the winter or in the morning is good. This situation sometimes results in a color different from what you see with your eyes. This is due to the color temperature in which the wavelength of light is expressed in Kelvin scale. The color temperature of the daylight film is set to 5500 ° k. If the daylight film is used, the color temperature is high because of the high color temperature in the shade or perforated light. This will appear a lot because the color temperature is not correct.

In general, red has a warm color and blue has a cold color, but unlike the general feeling, the color temperature is high in blue and low in red. In the picture of the building it is necessary to reproduce the warm tone to be aware of this.

In general, the color temperature changes at around 12 o'clock in the day and the color temperature of daylight film is set to 5500 ° k.

However, 5000 ° k is the ideal color temperature, which may vary depending on the season, climatic conditions, and places. Also, the color that appears in the picture can change depending on what time of day it was taken. Early dawn, before sunrise, appears blue because of its high color temperature, but as soon as the sun rises, the light becomes more reddish or orange because the blue tone is filtered by the air. Gradually, the correct color appears gradually so that the sun rises higher in the sky, and by noon, the color is almost accurate.

Kodak 100vs is used under normal conditions and push slide films are used in bad weather. Since the lens uses a 135m camera, it is recommended to use a zoom lens to increase the work efficiency.

The zoom lens used is the most effective zoom lens of 28-105mm. Shooting is done in the back light of most building photographs. In general, shooting under backlighting uses a method of over 1 1/2 stops or 2 stops. However, in this case, since the highlight part is often completely overwritten, 1/2 stop is added or decreased when adjusting the ISO sensitivity. You can use 2stop exposure compensation and spot metering to maximize the highlights.

In addition, by using the CPL filter to block the reflected light of the building it is possible to more accurately capture the outline of the building.

The pictures taken by the above-described picture taking method are sorted into data on a computer through a scanner (s601 and s602). A scanner can be used as a general flat scanner, but the resolution should be 300 dpi or higher using a drum scanner in consideration of color and image size.

The building data thus created is imported into a program that can be modified. There are many programs (Photoshop, Paintshop, Painter, etc.), but Photoshop is the most used program. This is because it is easy to work with various filters and layers.

Next, the imported building data is modified to best reflect the appearance of the required building, and non-modifiable buildings must create new buildings (s603).

(1) modification of a modifiable building

Select a building from the initial data received. Mainly modify the parts that cover the exterior of the building, such as trees, telephone poles and surrounding buildings. It also removes signs and banners from the building. These modified buildings are modified once again to be placed on the map. Modify the building by choosing the angle that best reflects the appearance of the building.

(2) creation of non-modifiable buildings

First, familiarize yourself with the shape of the building, and then form the exterior of the building by using similar or identical images such as blocks, marble, and wood. Then make the windows and doors of the building. When the exterior of the building is complete, the front and side are distinguished. As soon as possible, the front side is expressed as bright as the light and the side is slightly darkened.

On the other hand, after picking the exterior line of the modified building using the path and save it with a different name (S604). There are two ways to save files: pds and eps.

The reason for saving by pds method is to save the layer and path so that it can be modified later. The reason for saving by eps method is to combine layers and save only path. This is because the capacity can be reduced. By storing the saved building data in another folder, the data before revision is distinguished from the data after revision.

6B is a diagram illustrating a flow of a map making process.

After the map base plate is made (s611), the modified building is called up (s612), and the building is re-edited for the size and the outwards (s613), and the place name and accessories are inserted (s614). Insert a sign (s615).

The map is made through the above process, which will be described in detail below.

For the first time, a map base plate, that is, a background is created, which is a process of creating roads, zones, etc. to make a map (s611). Determine the range and direction to create the map to create the background part of the actual precision map. When you create a precision map as a background, you first scan the map, load it into Photoshop, and save the area as a path.

The size of the map is determined in advance to create a new document. In production, the higher the resolution, the better the output, but set to 150dpi for work. Import the path you saved in the newly created document and resize it to fit the size of the map.

This adjusted path marks where the building will go and fills the area with bright colors. The path will be a road outside the area designated by the path, so fill it with a color similar to asphalt. When marking roads, the center line, lane markings, pedestrian crossings, overpasses, bus stops, underpasses and the current location of subway entrances are indicated.

Next, the building is inserted in the background, which is a process of relocating the modified building on the map (s612 and s613). The size of the building is determined by the location of the building, the actual building size, and the surrounding environment. The important thing when arranging a building is to make it look too dense when the map is visible to the naked eye and to make sure it is not too empty.

The size of the building depends on the size of the surrounding buildings, their actual size, and how many buildings are in the area.

If the surrounding buildings are large, make them in a similar proportion to their size, and the size of the building changes according to the actual size. Also, the larger the number of buildings in a district, the smaller the size of the buildings.

When resizing and placing a building, place it from the top of the map. If there is an overlap in the layout, place it from the top to prevent the lower building from being hidden by the upper building.

In addition, if there is a part overlapping side by side, the order is determined according to the direction. For example, if the building faces left, place it from the right. If it's facing right, place it from the left. Of course, since we are working with layers, it doesn't matter which way to place them from, but the work is repeated, which reduces work efficiency.

Try to avoid overlapping parts as much as possible. If there are overlapping parts, try to make the exterior of the building visible. When representing a residential area or apartment complex, the layout should be taken into account in the actual form, but since a large number of buildings need to be placed in a small area, only a part of it is used.

In other words, adjust the quantity to eliminate the feeling of being too dense. In particular, housing complexes can be selected by copying two or three houses or villa-type buildings.

In order to prevent the buildings from floating in the air, use the eraser to erase the bottom of the building. At this time, the brush shape is used to give the hardness (Hardness) as much as possible to look soft rather than hard feeling. In doing so, the bottom of the building is attached to the ground and the other parts appear to be separated.

Alternatively, the bottom of the building can be filled with a sidewalk block. When the layout of the building is complete, make the map more realistic with street trees and sculptures.

When using these props should be arranged so that they do not feel too complicated or cluttered. If it is necessary, it should be adjusted to that quantity. After this process, fill in each local network and road name.

Finally, signage layout. This is a process of putting a signboard in each building on the map created in the process (s615). The size of the signboard shall be the size originally specified, but some errors are allowed.

The main program used to create signboards uses Adobe's Illustrator. Illustrator uses vector method, so even small images are not broken, so it is suitable for making signboards.

When placing a sign on the map, place it inside the building and out if it cannot be placed. When placed outside, avoid covering other buildings.

All of these maps are saved in EPS. The entire map is intended to create an independent image, taking into account the color and capacity of the EPS method.

Figure 6c is a diagram showing the flow of the billboard making process.

Creating a billboard, once created a frame (s621), and then seats the map, advertising and title bar (s622).

This will be described in detail below.

A document is created by designating a size and a resolution to be initially worked on (s621).

Set the size with about 3cm margin than the actual output size. This 3cm is intended to give a frame, not what it actually looks like.

The higher the resolution, the better the output, but set to 150dpi for work.

Guides are used to mark the place to place boxed ads, maps, and title bars on newly created documents.

Create a border around the area where you want to place the ad so that it appears as an independent ad.

Each advertisement, map, and title bar are called and placed in the document (s622).

When the deployment is complete, save it with a PDS extension. It's large, but it's meant to leave a layer for some modification on output.

6A through 6C describe specific cameras, films, image editing programs, and the like as examples, which are the cornerstones of providing better information to the user according to the present invention. Accordingly, the present invention is not limited to the above specific name, and other cameras, films, and image editing programs capable of providing information to the user may be used.

7 is a configuration diagram of another embodiment of a location information guide system based on a network according to the present invention.

FIG. 7 is a view for explaining a location information guide system based on a network according to the present invention, and shows a slight difference from FIG. This difference is because the main server of the location information guide system presented in detail through FIGS. 1 and 2 is represented by being divided into a web server, a file server, and a database (DB) server connected to the Internet.

In addition, the user is connected to a web server via the Internet using a client to receive the location information.

The web server receives a client's connection, processes a request from the client through data exchange with a file server and a database server, provides a map, and provides additional information such as advertisement and guidance.

8A to 8B are detailed diagrams illustrating an embodiment of a process for providing information by the location information guide system according to the present invention.

8A illustrates a local search according to a user's request.

The user checks the local search menu provided by the web server of the location information guide system through his client, and inputs the name of the region to search.

The entered local name is sent to the web server with the inquiry request.

The web server searches the local information table of the database server and outputs the local image name to the client.

After checking the local image name searched through the client, the user selects a specific region and requests it. The web server searches for the region image in the file server and delivers the image to the client according to the region image search request input from the user.

The client outputs it through a monitor and the like, and the user checks the searched area.

In FIG. 8B, the user's telephone search will be described.

The user checks the telephone search menu provided by the web server of the location information guide system through his client and inputs the telephone number to search.

The phone number entered is sent to the web server with the inquiry request.

The web server searches the telephone information table of the database server and outputs the local image name to the client.

After checking the local image name searched through the client, the user selects a specific region and requests it. The web server searches for the region image in the file server and delivers the image to the client according to the region image search request input from the user.

The client outputs it through a monitor and the like, and the user checks the searched area.

In FIG. 8C, mutual search of a user will be described.

The user checks the mutual search menu provided by the web server of the location information guide system through his client, and inputs a business name to search.

The entered business name is sent to the web server with the inquiry request.

The web server searches the mutual information table of the database server and outputs the searched local image name to the client.

After checking the local image name searched through the client, the user selects a specific region and requests it. The web server searches for the region image in the file server and delivers the image to the client according to the region image search request input from the user.

The client outputs it through a monitor and the like, and the user checks the searched area.

In FIG. 8D, the user's building search will be described.

The user checks the building search menu provided by the web server of the location information guide system through his client and inputs the building name to search.

The entered building name is sent to the web server along with the inquiry request.

The web server searches the building information table of the database server and outputs the searched building information to the user through the client.

When the user who checks the building information through the client requests building related image inquiry, the web server finds the relevant building related image from the file server and delivers it to the client according to the building related image inquiry request input from the user.

The client outputs it through a monitor and the like, and the user checks the found building.

In FIG. 8E, a user's advertisement text inquiry is described.

The user checks the advertisement menu provided by the web server of the location information guidance system or selects the advertisement of the map image through the client used by the user.
