Description

Realizing and retrieving methods of local and geographic informationon on the Internet}

The present invention relates to a method for implementing Internet stereoscopic geographic and regional information, and more particularly, to implement a pseudo-virtual space system, which is a connection system of maps that develop three-dimensional stereoscopic information in two-dimensional on an axisymmetric projection method. The present invention relates to a method of realizing three-dimensional geographical and regional information on the Internet, which searches a wide range of information based on geographical and regional information.

With the development of the Internet, information retrieval through the Internet is becoming a living. The user needs to go beyond the mere knowledge of the conventional information and take information that is one level higher, that is, information that seems to be experienced. However, the information searched through the Internet can improve the efficiency of the classification itself through a vocabulary-oriented abstract classification method, but it is different from the human perception of everyday experiences, so the connection with the real world is abstract, especially the real world. In the case of location information based on search, it is not only difficult to search, but also does not satisfy experiential needs. To compensate for this, three-dimensional simulations may be used. However, three-dimensional simulations have similar advantages to real spatial perception, whereas in perceptual space perception, the size changes according to the object's perspective distance, and the human's perspective must be shifted to perceive the back or side at a given line of sight. It is difficult to overcome the limitation that vision has to perceive three-dimensional space in two dimensions.

In addition, the three-dimensional geographic and local information provided on the Internet cannot be viewed from the opposite side, and only the whole can be viewed, which is different from the perception of the real world space. Because it is limited to one participant, the user only gets limited information.

Therefore, in the related art, as described above, the three-dimensional three-dimensional geographic and regional information implementation on the Internet is composed of a lexical center system that is far from the real world, or is in the form of a simulation. Due to this searchability, there was a problem that the user had to obtain limited information.

An object of the present invention is to solve the above problems, to construct a pseudo-virtual space system that expands the three-dimensional stereoscopic geographic region information of the real world in two-dimensional by the axisymmetric projection method, and all objects in the living space It is to provide a three-dimensional geographic and regional information realization method in the user-centered real-world internet where information resources can be used to search a wide range of information through a pseudo-virtual spatial system.

It can be implemented as.

In the individual map, real-world geographic and regional information is realized three-dimensionally by an axisymmetric projection method, and a road located at the center of the actual map or, in particular, an arbitrary axis that can develop three-dimensional information of the region, is set up. It may be implemented based on a road that is connected to the individual map of the area connected in accordance with the progress direction.

The detailed information is composed of basic information and additional information, and the basic information is objective information on the three-dimensional topography and features shown on the individual map, and the additional information is subjective information by a predetermined affiliate relationship according to the needs of the basic information subject. As a result, it can be embodied by dividing into commercial additional information related to economic activities and non-commercial additional information for providing convenience to users and activating a user-centered local community.

According to the present invention for achieving the above object, the three-dimensional geographic region information search method in the Internet, the user connected to the Internet by inputting in the search box to search, or by selecting the location of the map to select the corresponding individual map and Exploring three-dimensional information as if the terrain and features of the real world were walking on a street in a three-dimensional representation of axis-symmetric projection, and checking detailed information and internal modes of any three-dimensional features and features on the individual map Characterized in that the step is to search.

In the present invention, a parallel projection technique is used as a method for implementing three-dimensional geographic and regional information on the Internet. Projection degree technique is a method of unfolding the three-dimensional information on the two-dimensional plane can clearly express the relationship between the information arranged through the arbitrary deformation of the object within a predetermined range without moving the viewpoint. In the present invention, the axisymmetric projection method is used among the projection degree techniques. Since the axisymmetric projection method does not assume the vanishing point, the three-dimensional object is unfolded on the plane in a uniform state without any length variation between distances. It is possible to spread information evenly. Therefore, the axisymmetric projection method facilitates the construction of the empirical context in the space by minimizing the visual experience load according to the distance in the actual three-dimensional space.

Generally, the map is composed of national map, city map, county map and hibernation map based on administrative district. In the present invention, a lower attempt map is connected to a specific location of the national map, a lower county map is connected to a specific location of the trial map, and a lower hibernation map is connected to the county map. However, the axisymmetric projection method is used to implement the hibernating map representing the actual three-dimensional world, and additionally, there are internal modes and underground maps. Thus, the connection system of three-dimensional geographic and regional information transfer maps by axisymmetric projection method is defined as Pseudo Virtual Space System.

In the pseudo-virtual space system, a national map representing a country, a trial map divided into administrative districts, and a district map divided into sub-administration systems of the trial map are called area maps, and hibernated maps showing actual three-dimensional geographic and regional information. Is called an individual map. National maps, produced at the national level, show the general geography and topography of a country. The map of the province divided into sub-administrative areas on the national map is linked to the national map and shows the general geographic and topographical status of each province. Regional maps, linked to municipal maps and divided into sub-administrative districts, show the overall geographic and topographical status of each district.

The individual maps, which are linked to the area map and three-dimensional geographic and regional information such as various complex facilities and places on the road, buildings, and roads of each individual area by the axisymmetric projection method, are located at the center of the actual map. In this case, it sets an arbitrary axis to develop the three-dimensional information of the road or the special case, and is connected to the individual map of the connected area according to the direction of the road. In other words, individual maps are organized around roads. In the individual map, the actual buildings, sites, and various complex facilities and activities on the roads are represented in three dimensions by the axisymmetric projection method, and the left and right sides can be observed as if observed from the actual street. Detailed information on the three-dimensional topography and features shown on the individual map can be obtained through detailed information linked to the individual map, and internal and underground information of the three-dimensional topography and features not represented on the individual map can be obtained by selecting the internal mode. . If a specific location of an individual map is selected with a mouse, detailed information linked to the location information of the individual map is displayed. The detailed information is divided into basic information and additional information.

Basic information is objective information on three-dimensional topography and features shown on individual maps. In case of a building, it belongs to building name, business name, type of business, and contact information, and additional information is classified into commercial and non-profit additional information. do. Commercial additional information is subjective information by the subject of basic information, which is related to economic activities such as events, advertisements, announcements, homepage production or linkage. On the other hand, non-profit additional information is provided to provide convenience to the user and to activate a user-centered local community, which is composed of various hobbies, personal home pages, and local related information.

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

1 is a block diagram of a pseudo virtual space system applied to the present invention.

In the present invention, the pseudo-virtual space system includes a national map (100) showing a general geographic and topography of a country, a trial map (200) connected to a national map (100) and showing a general geographic and topographical status of each trial. , A regional map 300 connected to the city map 200 and showing the general geographic and topographical status of each district, and various and complex facilities on the buildings, sites, and roads of each individual region connected to the regional map 300. The three-dimensional geographic and regional information, such as the location and activity location, in three-dimensional maps of three-dimensional geographical projections, and the detailed information (500) for displaying information on the terrain and features shown on the individual maps (400). It is composed.

The national map 100, the city map 200, and the area map 300 are composed of image maps with location information. Each individual map 400 connected to the area map 300 sets a road located at the center of the actual map or an arbitrary axis to develop stereoscopic information of the area in a special case, and is connected according to the direction of the road. It is connected with the individual map 400 of the area. That is, the individual map 400 is composed of roads, and actual buildings, sites, and various complex facilities and activities on the roads are three-dimensionally represented by an axisymmetric projection method. Information on the stereoscopic terrain and features shown on the individual map 400 may be obtained through the detailed information 500 connected to the individual map 400. Although various input devices are possible, the present invention will be described with a mouse and a keyboard. When the mouse selects a specific area on the individual map 400, the detailed information 500 connected to the location information of the individual map 400 appears. The detailed information 500 is divided into basic information and additional information.

Basic information is objective information on the three-dimensional topography and features shown on the individual map 400, and in the case of a building, the building name, the name of the business place in the building, the type of business, and the contact information belong to it. It is divided into additional information. Commercial additional information is subjective information by the subject of basic information, which is related to economic activities such as events, advertisements, announcements, homepage production or linkage.

On the contrary, non-profit additional information is a variety of information for providing convenience to the user and activating a user-centered local community. Additional information is freely expressed in the pseudo-virtual space or implemented to make reservations and e-commerce through the affiliate site.

2A is a perspective view. In the case of expressing three-dimensional stereoscopic information in a perspective view, it is necessary to change an object and approach a manipulation due to a resolution degradation caused by perspective. 2B is a general projection view. When the three-dimensional stereoscopic information is represented in a general projection view, a direction change operation is required to solve the problem of the back information of the object being hidden. Figure 2c is an axisymmetric projection method used to expand the three-dimensional stereoscopic information of the real world on a two-dimensional plane in the present invention.

Unlike the perspective view of FIG. 2A or the general projection of FIG. 2B, the axisymmetric projection method, which is one of the projection view techniques, sets the center axis of the observer position and projects the information horizontally on the left and right sides by symmetrically projecting the left and right directions. To make it possible. Therefore, three-dimensional stereoscopic information can be easily implemented without special manipulation such as perspective control of perspective view or reorientation for backside information in general projection view.

3 is an individual map 400 implemented by the axisymmetric projection method. Each individual map 400 constituting the pseudo-virtual space system sets a road located at the center of the actual map or an arbitrary axis that can develop three-dimensional information of the region in a special case, and is connected according to the direction of the road. It is connected with the individual map 400 of the area. In order to move to another area connected to the direction of the road, one of the direction indications such as 400a, 400b, 400c, and 400d of FIG. 3 is selected to move to the adjacent individual map 400. The individual map 400 expresses various and complex facilities and activity places on each building, site, and road in each individual region, and video location information for making use of the scene with various symbols.

More detailed information about the stereoscopic information shown in the individual map 400 is implemented by the detailed information 500 connected to the corresponding location. In the case of a building among the three-dimensional topography and features shown in the individual map 400, information such as the floor type, business name, business type, contact information, business content, events, advertisements, and site linking of the building includes location information of the individual map when the building is selected. This can be checked through the detailed information linked to. However, an internal mode is provided to provide information that was not represented in the individual map 400 such as the internal layout from the basement floor to the top floor of each building.

In the individual map 400 of FIG. 3, the building 500a indicates that the internal mode is supported. 4 is a screen provided when the internal mode of the building 500a of FIG. 3 is selected. When the internal mode is selected, detailed information can be checked based on the internal layout information of the building.

The database of the present invention is composed of a map database 600 and a detailed information database 700.

5A relates to a map database 700. Map database 700 is a database for map information on each map, area map, individual map, and internal maps that form an internal mode such as an internal layout and an underground road of a building, and a map unique for distinguishing each map. It consists of a map item having a real map corresponding to a code item and a map unique code, a location item having a location value in each map, and a connection information item and a central distance dimension item for connection information according to the location value.

FIG. 5B is a detailed information database 700 for showing information on three-dimensional geography and regions displayed on individual maps. The detailed information database 700 is composed of detailed unique code items, classification code items, basic information items representing three-dimensional geographic region information at the location of the map, and additional information items.

In the present invention, the internal mode or the underground maps of the building which could not be obtained from the whole map 100, the city map 200, the area map 300, the individual map 400 and the individual map 400 may be assigned to each map unique code. Have. The map unique code of the map database 600 is selected by the search, and the connection information according to the position of the selected map is driven. The connection information item of the map database 600 comes with information such as other map unique codes and detailed unique codes. When the content of the connection information item is determined, the map information code is connected to the corresponding map in the map database 600. In the case of a detailed unique code, corresponding basic information and additional information are connected in the detailed information database 700.

The search method in the pseudo virtual space system will be described in detail with reference to the search process flowchart of FIG. 6.

A user who accesses the Internet may search by using a search box in the pseudo virtual space system and selecting a map location directly.

Searching by typing in the search box, or by selecting the location of the map to select the corresponding individual map 400 (S1), and the individual map 400 in which the terrain and features of the real world is expressed in three-dimensional symmetric projection method In step S2 of searching stereoscopic information as if walking on a street, and checking the detailed information 500 and the internal mode of any three-dimensional terrain and features on the individual map 400 are searched in step S3. .

Step (S1) of accessing the individual map 400 by starting a search on the initial screen on which the national map 100 is displayed may be performed by inputting the search contents into the search box or selecting the search table according to the classification table of the search box (S10). In this case, the method of searching and searching directly on the individual map (S11) is selectable. Although the national map 100 is shown as an initial screen in the present invention, the initial screen may be designated as an arbitrary map according to the user's convenience among national maps, city maps, and local maps.

When approaching the individual map 400 to record the route or select the route record (S20) in the step (S2) to search the connected individual map 400, the initial selected individual map 400 in the route recording window (S21) is initialized. It is left as a map and the center distance dimension values of the map information database 600 are summed. The route search (S22) can be performed with the individual map 400 connected as if the actual world's three-dimensional geographic and topographical information were walked on the individual map 400 three-dimensionally produced by the axisymmetric projection method.

In the step (S3) of confirming detailed stereoscopic geographic region information, confirming the detailed information 500 and internal mode of the stereoscopic geographical region information displayed on the individual map 400 in a specific location or route search as a result of the search ( S30).

7 illustrates an initial search step of activating and searching a search box in the initial screen of the present invention. When the search area is selected, the search contents are input, and the search is performed, the result area map 300 is shown in FIG. 8. When the search area is further defined, the individual map 400 may be immediately displayed as shown in FIG. 9. When the search is performed, the detailed information database 700 is searched to find an individual map 400 that includes the contents corresponding to the search contents, and displayed as a search symbol on the corresponding local map 300. The basis of the detailed information database 700 is shown. Information is shown on one end of the search screen as shown in FIG. In the case of a large number of search results, several search symbols appear on the area map 300. When the mouse is moved to the search symbol, the search symbol is highlighted on the local map 300. Select the search symbol on the area map, or select the basic information provided at one end of the search screen to access the individual map 400.

When the route record is selected in the individual map 400, when moving from the initially set individual map 400 to another individual map 400, the numerical value of the central distance dimension item of the map information database 600 is maintained until the end of the route recording. In addition, the sum of distances for each section of the individual map 400 may be obtained. 9 shows that the search results are represented by search symbols on the individual map 400. The detailed information 500 may be confirmed by selecting a search symbol displayed on the individual map 400. In the selected individual map 400, the user can search the route as if walking the actual distance and select a specific location desired to check detailed information on the three-dimensional terrain and features.

When each map is loaded, the location information and the connection information corresponding to the location are loaded when the location of the map is selected, without loading all the location information and the detailed information corresponding to the connection information together. Quick search is possible. In the case of large-scale buildings among the three-dimensional topography and features of the individual map 400, it is composed of several businesses and more information on the internal layout is required. In addition, video information may be required for a sense of realism.

As such, when the individual map 400 itself lacks the expression of three-dimensional topography and features, an internal mode is provided so that separate maps for the internal layout and the underground road of the building are connected. At this time, the internal map connected to the three-dimensional terrain and features of the individual map also has a map unique code, and the internal mode display 500a is displayed on the individual map 400. When the internal mode display 500a on the individual map 400 is selected, since the connection information connected to the location item of the individual map 400 has the map unique code of the internal map, the corresponding internal map is loaded. Moving from the individual map 400 to the connected adjacent individual map 400 selects one of the direction indications displayed on the road of the individual map 400 and finds the map unique code, which is the connection information at the corresponding location, in the map database. 400).

FIG. 10 is a navigation view for searching for a specific area on a two-dimensional plane map, and FIGS. 11A to 11F are diagrams of moving the same area of FIG. 10 along a center road of an individual map 400 in a pseudo virtual space constructed according to the present invention. It is showing the process of searching.

The method of searching from FIG. 11A to FIG. 11F includes selecting a in the south direction of the intersection in FIG. 11A to reach FIG. 11B, and selecting a in the right direction at the intersection of FIG. 11B to reach FIG. 11C, and then right in FIG. 11C. Fig. 11F shows a case in which the direction a is selected to reach FIG. 11F and a case in which the right direction b of the cross section is selected in FIG. 11A to reach FIG. 11E and a right direction b in FIG. 11E is reached in FIG. 11F. .

As the three-dimensional geographic region information search for the front, rear, left and right surroundings moving along the central road as described above, it provides a search method that can increase the realism, such as walking the dense real city street.

Therefore, according to the present invention, by implementing the three-dimensional stereoscopic geographic region information using the axisymmetric projection method, it is possible to obtain an effect such as directly expanding the three-dimensional space on two dimensions without any special manipulation, and the user can view the sides of the road directly. Simultaneously see and move, so there is an effect that can increase the reality of walking the actual city streets.

In addition, it creates a map system called pseudo-virtual space system and registers objective information about all three-dimensional topography and features as basic information to enable user-centered information retrieval. The subjective information is related to economic activities to commercial additional information, whereas the information for providing convenience to the user and activating the user-centered local community is divided into non-profit additional information. It is effective to create local portal sites that link local information through local information resources.
