Description

Method, device and system for providing location information using map information {METHOD, DEVICE AND SYSTEM FOR PROVIDING LOCATION INFORMATION USING MAP INFORMATION}

The present invention relates to a method, a recording medium, and a system capable of providing location information using map information provided from a homepage. More specifically, the present invention provides a map, a map, The present invention relates to a method, a recording medium, and a system which can provide location information indicating a location of a user to map information such as an indoor view and a guide map to a location information terminal possessed by a user.

1 is a diagram illustrating a schematic configuration of a general GPS system.

Referring to FIG. 1, GPS is generally transmitted from four satellites 100 to a GPS receiver 105 owned by a user with a specially coded satellite signal. The satellite 100 rotates in a circular orbit around the earth with a period of about 12 hours at an altitude of about 20,000 km. At this time, four satellites 100 are present in six circular orbits having an orbital inclination angle of 55 degrees, and are composed of a total of 24 satellites. Each satellite 100 is equipped with an atomic clock, and at any point on earth, since at least four satellites 100 are always located in the visibility, the GPS receiver 105 is a satellite 100 within the clock. Select four suitable satellites from among them and receive satellite signals from them to measure their position and speed.

That is, since positions for four satellites captured by the user's watch are specified, three-dimensional positions (X, Y, and Z) of the user's latitude, longitude, and altitude from the position of the satellite and the speed corresponding to the visual deviation ( T) can be calculated. The frequency of the satellite signal transmitted from a satellite that is a Space Vehicle (SV) corresponds to 1,575.42 MHz (L1) and 1,227.6 MHz (L2), and compensates the delay of the ionospheric layer by the L1 and L2 signals.

In this way, GPS can measure the position and moving speed of moving objects such as aircraft, ships, and cars by using satellites located on Earth's orbit wherever they are in the world. It is widely used in geographic information systems (GIS) such as production. In particular, recently, GPS receivers have been manufactured as personal portable devices, so that individuals can use such GPS.

As described above, as the development of a location tracking device such as a navigation system is accelerated, a map is required for not only aircraft, vehicles, ships, but also various electronic devices and service industries.

Currently used maps are classified into paper maps and numerical maps. Paper maps are produced by reviewing and editing additional information for various purposes based on the national basic maps generated by the National Geographical Institute. Such a paper map is first made of a film, and then completed by printing and publishing the produced film. The completed paper map is sold through various media or used as basic data for digital mapping.

A digital map is a map in which the information of a paper map is digitized into a set of geometric figure elements or pixels in the form of points, lines, and planes. The digital map is manufactured by scanning a paper map and converting the scanning data into geometric figure data such as points, lines, and surfaces.

These existing maps are produced on the basis of the national base maps issued at 1: 5000, 1: 25000 and 1: 50000 accumulatively, but since the update period of the national base map is more than one year, the latest maps and figures are available. Difficult to include in maps and three-dimensional maps.

In addition, maps produced through national basic maps and actual survey activities are lost because much information is produced by generalizing or abstracting the surface.

In addition, even when a map is created, there is an inconvenience of updating the latest map information from time to time.

In addition, when a user with the existing GPS receiver 105 is located in a forested mountain or a valley, or is located between high-rise buildings, satellites transmitted from the satellite 100 by these forests or buildings. You will not be able to receive the signal.

In particular, in recent years, as the city develops, and as the population increases, the height of tall buildings becomes higher, and since the movement of preserving forests for the purpose of nature conservation is active, the GPS receiver 105 normally performs satellite signals in such places. There is a problem that is not easy to receive.

The existing location tracking system can be used as a CNS (Personal Navigation System), which can be used as a guide to the road while climbing, traveling and cycling as well as CNS (Car Navigation System). In addition, route search through the map screen PNS and CNS are provided as a general location information system.

However, the existing location information system is inconvenient to refer to the map data contained in the CD ROM 120 or to store the map data in a rewritable flash memory 120 and update the map data at any time.

However, such a location information system only inputs and stores information on a large-scale national map in advance and maps it to the current location on the map.

In addition, the existing location information system only provides location information based on the topographic map.

In the existing location information system, only information corresponding to the map is provided, and there is a limit in providing detailed information in a specific range.

In addition, there is a problem in that the GPS location information terminal cannot be used in an area that does not have a GPS receiving system or cannot receive a GPS signal.

In addition, it is inconvenient to have a memory 120 in which map information pre-fabricated on a large scale is stored.

Therefore, the present invention is to solve the above problems, without creating map information of the area to provide the location information service, location information using the map information provided by the homepage of the company, public office, etc. located in the area It is to provide a method, a recording medium and a system that can provide.

It is also an object of the present invention to provide various location information services using map information provided on an existing homepage without creating or using nationwide map information data. That is, the present invention is not limited to providing location information based on the existing topographic map, but providing location information by using map information such as a map, a location map, a floor map, and an indoor map provided from a homepage.

Existing homepages include subpages that provide various map information according to the nature of the subject providing the homepage. Since the subpage provides the map information by various methods such as a graphic and a flash, the map page may use the map information provided from the homepage to provide various location information corresponding to the intention of the map information provider.

It is also an object of the present invention to provide location information without costly map information.

In addition, an object of the present invention is a method that can be accurately mapped on the map using the location information received from the electronic reference point processing the radio signal to calculate the location of the user at the request of the user in a fixed position at a specified location In addition, the present invention provides a recording medium and a system.

The present invention also provides a method, a recording medium, and a system capable of receiving coordinate calculation information from an electronic reference point including coordinate information as well as a GPS satellite.

It is also an object of the present invention to provide a method, a recording medium and a system capable of receiving and processing the map information in real time from a server without having a memory including separate map information data.

The GPS satellite 100 performs a function of transmitting coordinate calculation information to the location information terminal 120. Detailed description of the GPS satellites 100 is omitted in FIG. 1.

When the number of the GPS satellites 100 is three, the coordinate information of the location information terminal 120 may be calculated. When the number of the GPS satellites 100 is four, not only the coordinate information but also the speed may be calculated.

The electronic reference point 110 may transmit coordinate calculation information stored in the memory to the location information terminal 120. The electronic reference point 110 receives coordinate calculation information from the GPS satellite 100, calculates coordinates of the electronic reference point 110, and stores the calculated coordinate information in a memory.

Here, the map information preferably includes coordinate values of three or more points for transformation of the coordinate system.

3A and 3B are flowcharts illustrating the prerequisite procedure of the system for providing location information according to an exemplary embodiment of the present invention.

The map information provided by the present invention includes coordinate values such as directions, indoor views, and the like provided by the existing homepage. In order to provide location information using the map information, a coordinate system of the map information should be calculated, and the current location of the accurate location information terminal should be displayed on the map information using the generated coordinate system.

In the present invention, the process of calculating the location information using the map information may be performed by the location information terminal, or may be performed by the location information providing server or the map information providing server that provides the map information.

However, for the convenience of the following description, the location information providing server is assumed to be a server for providing location information, the map information providing server simply provides map information, and the process of calculating the map information as location information is performed in the location information terminal. It will be described on the premise that it is performed.

Hereinafter, a procedure of providing location information according to the present invention will be described with reference to FIGS. 3A and 3B.

In step 300, the electronic reference point receives coordinate calculation information from the GPS satellites, and calculates coordinate information of the electronic reference point using the coordinate calculation information received in step 303.

The coordinate calculation method may calculate a distance using a propagation speed from a user receiver to a satellite, and calculate coordinates of the electronic reference point by triangulation using a known satellite position.

In step 306, the electronic reference point stores the calculated coordinate information in a memory provided in the electronic reference point. The coordinate information may then be transmitted to the location information terminal and used when calculating the coordinate information of the location information terminal.

In step 309, the location information terminal determines where to receive the coordinate calculation information.

According to the present invention, the position information terminal may not only receive coordinate calculation information from a GPS satellite, but also receive coordinate information from an electronic reference point.

In a typical area, the location information terminal may receive coordinate calculation information from the GPS satellites as in step 313.

In addition, coordinate calculation information may be received from an electronic reference point in a preset area such as an area in which GPS signals cannot be received. That is, the location information terminal may receive the coordinate calculation information request signal at the electronic reference point in step 316, and receive the coordinate calculation information from the electronic reference point in step 319.

In step 323, the location information terminal calculates current coordinate information of the location information terminal by using the received coordinate calculation information. The coordinate calculation method is the same as the coordinate calculation method at the electronic reference point described in step 303.

The location information terminal generates a location information request signal or a map information request signal in step 326. In this case, the location information request signal should include the coordinate information generated in step 323.

In step 329, the location information terminal transmits a location information request signal to the location information providing server or a map information request signal to the map information providing server.

In operation 333, the location information providing server or the map information providing server extracts map information.

According to the present invention, the map information providing server may simply provide map information including three or more coordinate values. When the map information is provided, the process of converting the map information into location information may be performed by the location information terminal.

When source map information is provided as map information, location information capable of displaying the location of the location information terminal is generated through conversion, mapping, and user location designation of the source map information.

On the other hand, when mapping map information is generated as map information, location information is generated by performing only a user location designation step on the mapping map information.

When the location information providing server generates location information indicating the location of the location information terminal on the map information and transmits the location information to the location information terminal, the location information terminal displays the received location information without a separate calculation process. Therefore, the location information request signal should include the coordinate information of the location information terminal.

Hereinafter, a description will be given based on a case where source map information is provided as map information.

That is, the location information providing server or the map information providing server extracts the map information in step 333. In operation 339, the map information providing server transmits the map information to the location information terminal. After receiving the map information, the location information terminal generates the location information by performing the conversion process of step 343, the mapping process of step 346, and the user location designation process of step 349.

In contrast, the location information providing server calculates the conversion process of step 343, the mapping process of step 346, and the user location designation process of step 349, and generates location information.

In step 363, the location information providing server transmits the generated location information to the location information terminal.

In step 366, the location information terminal displays the location information generated in the location information terminal or the location information received from the location information providing server to an output device coupled to the location information terminal.

In FIG. 3B, the source map information is extracted as the map information and the location information is generated.

However, the location information server may receive the source map information and generate the mapping map information in advance, extract the mapping map information, and perform only the user location designation step to transmit the location information to the location information terminal.

That is, when the terminal receives the location information request signal, it is natural that the mapping map information corresponding to the location information request signal can be extracted and provided.

3C to 3E are diagrams illustrating a difference between map information and location information according to an exemplary embodiment of the present invention.

The information according to the present invention is divided into map information and location information, and the map information is divided into source map information and mapping map information.

Referring to FIG. 3C, source map information including three or more coordinate values is shown. 3D, mapping map information in which a coordinate system is generated and map information is mapped using the coordinate values is illustrated.

3E illustrates location information in which the location of the terminal possessed by the user is shown in the mapping map information. (The illustration of the coordinate system is omitted in FIG. 3E.)

That is, mapping map information is generated through a transformation and mapping step using source map information, and location information is generated through a user location designation step using the mapping map information.

The conversion, mapping, and user location designation step may be performed by a server or a terminal, and the step performed by the type of information is determined.

Hereinafter, with reference to Table 1 will be described.

If location information is to be provided from a location providing server or a map providing server, if the extracted information is source map information, the location information should be generated and transmitted by performing the steps of conversion, mapping, and user location designation. In this case, if the extracted information is mapping map information, the location providing server or the map providing server may generate the location information and transmit the location information to the location information terminal only through the steps of user location designation.

In addition, when the location providing server or the map providing server should provide the mapping map information, if the extracted information is the source map information, the mapping map information should be generated and transmitted by performing the transformation and mapping steps. If the extracted information is mapping map information, the extracted information may be transmitted to the location information terminal without any step. Of course, in this case, generating the location information using the mapping map information is performed in the location information terminal.

In addition, when source map information is to be provided from a location providing server or a map providing server, when the source map information is extracted and transmitted to a location information terminal, a user location information terminal converts, maps, and uses the source map information. Follow the steps in Positioning to generate location information.

Hereinafter, although the location information providing server provides location information and the map information providing server provides the source map information, the present invention is not limited to the above embodiments. Of course, it can be changed according to the type of, that is, the source map information, the mapping map information.
