[0011]

Embodiments of the present invention will be described below with reference to the drawings.

<1. First Embodiment> FIG. 1 is a diagram showing a geographic information system 1 according to an embodiment of the present invention. As shown in FIG. 1, this geographic information system 1
As an example, the two computers 100 and 200 are connected to a communication network 3 such as the Internet so that they can communicate with each other. Each of the computers 100 and 200 is realized by a general computer including a memory, a CPU, a magnetic disk, a display, and the like.

The computer 200 stores map information inside, and is configured to be able to display the map information on a display.

On the other hand, the computer 100 is a means for providing the computer 200 with content information associated with the map information. The computer 100 reads various contents 40 such as music, images, sentences, etc. from predetermined media 41, 42 and digitally reads them. The digital data is converted into data, and the digital data is supplied to the computer 200 via the communication network 3 as content information.

[0015] Here, the content refers to a content that can be associated with a specific position in the map information, and is an image, music, characters, text, and other information.

When the computer 100 converts predetermined content into digital data or transmits digitalized content information via a communication network, the computer 100 transmits position information to the content information. Add. The position information allows the computer 200 to easily associate the map information with the content information.

FIG. 2 is a block diagram schematically showing the functional means of the geographic information system 1. As shown in FIG. 2, a computer 100 serving as a content supply unit includes:
A position information adding unit 10 and a position information database (hereinafter, referred to as a position information database)
It is called a position information DB. ) 110 and a memory 120. The memory 120 stores current position (current position) information on the computer 100. On the other hand, a computer 20 for reproducing and displaying map information
0 denotes a reproduction unit 20, a map information database (hereinafter, referred to as a map information DB) 210, an operation input unit 202,
And a display 201.
1 is configured to display map information and reproduce and output various contents.

In the computer 100, the contents 40
Is input, the content 40 is converted into digital data, and the position information adding unit 10 functions to add the position information to the content information. The position information added by the computer 100 includes two types of position information, ie, original position information and current position information, and the content information 3 generated by the position information adding unit 10.
0 is as shown in FIG. That is, in the content information 30, as shown in FIG. 3, original position information 31a and current position information 31b are added as position information 31 to the head area of the entity data 32 relating to the content.

The original position information 31a is position information related to the contents of the contents,
0, the position is specified by the function of the recognition processing unit 11 and the position specifying unit 12, and the latitude, longitude,
Position information such as altitude is added. For example, by performing a click operation or the like at a specific position on the map displayed on the display 201 in the computer 200, it is convenient if a landscape image corresponding to the position is displayed or music suitable for the landscape is played. . Therefore, by adding the original position information 31a to the content information 30, it is possible to associate a position related to the content of the content with the map information. For example, when the content is a landscape image of Oze, the image is associated with the position of Oze in the map information.

Here, when associating the map information with the map information, it is often unclear on the computer 100 what kind of map data is stored in the computer 200. Considering that the position information can be performed, it is preferable that the position information set as the original position information is represented by longitude, latitude, and altitude.

More specifically, a method for setting the original position information 31a will be described.

Recognition processing unit 1 in position information adding unit 10
A processing unit 1 extracts and recognizes various materials included in the content by performing various recognition processes such as voice recognition, image recognition, and character recognition.
It extracts and recognizes materials including geographic elements from images and text).

If the content is music, the recognition processing unit 11 performs a voice recognition process to specify a musical instrument having a locality from the timbre of the music and the like, and recognizes a lyric portion by voice to obtain a geographical location. Extract words. The geographical word is registered in a database or the like in advance, and when a target word exists in the database, the word is specified as a geographical word. For example,
If the music of the content is a bagpipe,
The recognition processing unit 11 can determine that the instrument being used is a bagpipe by performing frequency analysis or the like and referring to data in which the frequency and the instrument name are associated with each other. Extract words.
Since the bagpipe is geographically associated with Scotland, the recognition processing unit 11 can specify “bagpipe” as a geographic word by referring to the database.

When the content is a landscape image,
The recognition processing unit 11 performs image recognition processing to extract each material included in the image by contour extraction or the like, evaluates a shape, a hue, and the like, and searches a predetermined database based on the shape, the hue, and the like. I do. If the database includes a material whose shape or hue matches (or approximates), it is determined that the material is included in the image. As a result, a geographic word relating to the material can be extracted from the database.
In this way, a geographic word can be specified from each material obtained by image recognition. For example, when the content is a landscape image of New York, the recognition processing unit 11 extracts a material such as the Statue of Liberty and uses it as a target of a database search, so that a geographical position can be specified. "Statue of Liberty" can be extracted.

When the content is a text, the recognition processing unit 11 performs a character recognition process to extract a geographic word from the text. For example, a geographical word such as "Tokyo" or "Osaka" is extracted and specified from the text. Also in this case, by extracting a character string that matches a geographic word registered in a predetermined database, a geographic word can be extracted and specified.

Then, the geographical word extracted by the recognition processing section 11 is given to the position specifying section 12, and the position specifying section 1
2 identifies the position (latitude, longitude, altitude, etc.) corresponding to the geographic word by referring to the position information DB 110. That is, the position information DB 110 stores table data and the like in which position information is associated with each of a plurality of geographical words.
By searching a geographical word as search data for 110, it is possible to specify a position associated with the geographical word.

A plurality of pieces of position information may be set in the original position information 31a. For example, if one content is an image representing the eight views of Omi, there are eight corresponding position information. In such a case, eight position information is added as the original position information 31a. You may.

Next, the current position information 31b is position information indicating the position where the content of the content actually exists, and is added to the content information by the position information adding unit 10. Since the current position information 31b is also for indicating the position on the map, the original position information 31a
Similarly to the above, position information represented by at least latitude, longitude, altitude and the like is included so as to be able to correspond to arbitrary map data.

When it is necessary to acquire the contents of the contents via a communication network 3 such as the Internet, in addition to the above-mentioned position information, a URL (Universal Resource Locator) is added.
ater) and IP (Internet Proto)
col) Position information or the like represented by an address may be added. For example, when it is desired to check the current crowded situation inside a department store with an image, it is necessary to acquire an image of a camera installed inside the department store in real time. In this case, since the entity data 32 included in the content information 30 acquired in the past cannot be said to be the current image, the computer accesses the computer at the location where the content of the content actually exists to easily obtain the current latest image. It is preferable to be able to do so. Therefore, by additionally adding position information (position information for acquiring content) expressed by a URL or an IP address to the current position information 31a, it is possible to easily acquire the content of the content.

The current position information corresponding to the position of the computer 100 is stored in the memory 120, and the position information adding section 10 reads out the current position information from the memory 120 and adds it to the content information 30. Note that the current position information stored in the memory 120 may be set in advance according to the installation position of the computer 100, or may be set by position detection means such as a GPS as described later.

The current position information 31b is used as a relay point (relay computer) when the content information 30 is transmitted.
, The relay computer having the same configuration as the computer 100 changes or adds the current position information 31b. When the content is supplied, when the current position information 31b is finally supplied to the computer 200, the information becomes history information indicating the route through which the content was supplied.

The position information adding section 10 outputs the current position information 3
When setting positional information such as latitude, longitude, altitude, etc. as 1b, select a mode to be enabled from among three modes, an absolute position mode, a relative position mode, and an apparent position mode, as necessary. Adds information.

The absolute position mode is a mode in which a position is represented by absolute coordinate values such as latitude, longitude, altitude, and the like. Also,
The relative position mode is a mode in which a position is indicated by a direction and a distance from a certain reference point, or a position is indicated by a difference in latitude, longitude, altitude, and the like from a certain reference point. In the absolute position mode, when indicating the location of the content on the map in the computer 200, a correspondence relationship with the map information can be performed. Further, in the relative position mode, the displacement from the position of the reference point can be expressed in a vector format, so that the position information is in a form more suitable for computer processing. Processing such as displaying a transportation route on a map is made more efficient.

The apparent position mode is a mode for setting the current position at another position for convenience rather than at the position where the actual content exists. For example,
In some cases, the homepage of company B is set up on a computer owned by company A, and the homepage may include contents owned by company B. In this case, strictly speaking, the current position information is the server installation position of company A, but considering that the owner of the content is company B,
It is preferable to set the current position to a position where company B exists. Because, on the map, the location of the content is displayed as the location of Company A, which is not related to the owner,
This is because it is preferable to display the content at the position of Company B, which is the owner of the content. Therefore, in such a case, in the apparent position mode, not the actual position of the content but the position more preferable in handling can be set as the current position.

Since the apparent position mode is a mode for position information for associating with map information, for example, whether or not the position information such as latitude, longitude and altitude is apparent, It does not apply to location information represented by an IP address. This is because if the apparent position mode is applied to these, the latest content information cannot be obtained.

Table 1 shows a simple example of such current position information 31b.

[0037]

[Table 1]

In the current position information 31b shown in Table 1, the content existence position is indicated by both the absolute position and the relative position, the absolute position mode is “ON”, and the relative position mode is “ "Sleep".
Therefore, in the state of Table 1, the absolute position mode is valid, and the relative position mode is in the sleep state. In the absolute position mode, latitude, longitude, altitude, and the like are indicated by absolute coordinate values, and in the relative position mode, displacement in the latitude, longitude, and altitude directions from the reference point is indicated. Although not shown in Table 1, the coordinate value of the reference point may be added to the relative position mode. In other columns, ON / OFF information of the apparent position mode, history information, and the like are stored. Therefore, in the current position information 31b of Table 1, the current position in the absolute position mode is an apparent position, which means that it is different from the exact position where the content exists.

Further, the current position information is added to the relative positions in Table 1 at each relay point of the communication network 3, and three pieces of position information are added as histories. Therefore, it is possible to clarify the route through which the content information 30 was supplied to the computer 200 from the history, and it is also possible for the computer 200 to display the route on a map.

In Table 1, although the position information represented by the URL, the IP address, etc. is not shown,
Of course, these may be added. Table 1
When generating the history information of the current position as described above, the time via each relay point may be added as attached data. By adding the time data, the passing time of each relay point in the content transmission path can be known, and the time required for transmitting the content can be easily calculated.

As described above, the position information 31 is added to the content information 30 by the computer 100, and the computer 200 having the map information via the communication network 3.
Supplied to When another computer intervenes as a relay computer in the communication network 3 between the computers 100 and 200, the relay computer also has the same configuration and operation as the computer 100 described above, and the current position of the position information is used. Add information.

When the computer 200 acquires the content information, the association processing unit 21 of the reproducing unit 20 functions to associate the specific position of the map information stored in the map information DB 210 with the content. The association is performed for both the original position information 31a and the current position information 31b. And
The reproducing unit 20 reads out the map information associated with the content from the map information DB 210, and displays the map on the display 201.

Therefore, in the computer 200,
When displaying map information on the display 201, it is possible to associate a content such as an image, music, and text related to a specific position on the map with a specific position on the map,
The position where the content actually exists can also be displayed.

For example, when an operator (operator)
By operating the operation input unit 202 including a keyboard, pen input, and the like, for example, when a specific point on a map is specified, the content associated with the specific position is reproduced.

That is, since the correspondence between the map information and the contents is performed by the original position information 31a, the operator designates a specific position on the map and extracts an image or the like related to the position (or area). You can do it. Specifically, when the content is an image, an image related to the position (or area) specified by the operator is displayed on the display 201, and
If it is a sentence, the sentence is displayed on the display 201, and if the content is music,
Music related to the position designated by the operator is played from a speaker (not shown).

When the operator gives an instruction to display the location of the content from the operation input unit 202,
The playback unit 20 displays the location of the content on a map using a circular symbol or the like based on the current location information. further,
When history information of the current position is formed by adding the current position information at each relay point,
Based on the history information, it is also possible to display the position through the current position on a map. By displaying the current position of the content on the map based on the current position information in this manner, the operator can confirm the location of the content, and determine the route through which the content has been transmitted. It is also possible to confirm.

FIG. 4 is a diagram showing an example in which a map is displayed based on the history information of the current position. In the history display shown in FIG. 4, it is easily found that the content obtained via the communication network 3 is obtained sequentially through the positions P1, P2, and P3 on the map, and the source of the content is determined. It is also possible to specify.

The communication network 3 is not a communication network such as the Internet, for example, but two computers at positions P1 and P2 are directly connected to each other by a telephone line or the like. It is assumed that the content is transferred to the computer at P2, and thereafter, the content is transferred from the computer at position P2 to the computer at position P3 directly connected by a telephone line or the like. In such a case, it is particularly useful for the operator to display the route of the content on the map based on the history information, and the source of the content and the like can be easily clarified.

The computer 100 is, for example, a computer mounted on an automobile or the like, and the computer is provided with position detecting means such as a GPS, and the content to be transmitted is identification information unique to the automobile or the like. In some cases, if the display based on the current position information is performed by the computer 200, the current position of the vehicle is displayed on a map, and the display based on the history information is performed. The history can be displayed on a map. In this case, the current position information stored in the memory 120 is the position information detected by position detecting means such as a GPS, and every time the position information is sequentially updated, the position information adding unit 10 outputs the current position information. 31b is configured to be updated or added. Therefore, if such a system is configured, the geographic information system 1 according to the present embodiment can be used also as an operation management system for an automobile or the like.

Further, if such a computer 100 is miniaturized and realized as a portable device, the specific position of the specific person can be carried by the computer 200 by causing the specific person to carry the computer 100. Can be displayed on a map.

As described above, in the geographic information system 1 of this embodiment, the computer 100 on the content supply side
Is provided with a position information adding unit 10 for adding position information 31 to the content information 30. A computer 200 that displays the map information sends the content information 30 to the specific position A reproducing unit 20 that reproduces the images in association with each other is provided. Therefore, the content can be easily and efficiently associated with a specific position in the map information, and the content can be displayed in association with the map.

Further, the position information adding section 10 includes a recognition processing section 11 for recognizing a material included in the content information 30, and is configured to generate and add position information based on the content of the recognized material. Therefore, it is possible to specify a position related to the content of the content and add position information about the specified position.

Further, when associating with the map information by hand as in the past, it was impossible to add the current position information to the content information as in this embodiment. In the embodiment, since the position information is added by the computer 100 on the content supply side, the current position information of the content that cannot be grasped by the computer 200 that reproduces and displays the content in association with the map information is stored. Can also be added. By adding the current position information as well, it is possible to specify the transmission source and the acquisition route of the content, and when the computer 100 moves, real-time position information is added to the content information. It can be added.

<2. Second Embodiment> Next, a second embodiment will be described. Here, the computer 10 in the geographic information system 1 of the first embodiment is described.
0, another embodiment of a mechanism for adding position information will be described.

FIG. 5 shows a computer 10 according to this embodiment.
It is a figure showing the data flow in 0. The computer 100 is provided with a digitization processing unit 51 for converting a content into digital data, a keyword setting unit 52 for setting a keyword related to the content, and the above-described position information adding unit 10.

For example, when registering multimedia contents such as images and music in a database or the like, a keyword is set for each content in order to efficiently search and extract the content information. That is a very effective technique. In this case, for example, the title of the image or music, the author, the date of creation, the performer, all or a part of the lyrics, those used for the composition of the content (the name of the instrument used for the performance, Keywords, such as the type of lens being used), words representing the characteristics of the content (scenery, flowers, Mt. Fuji, Osaka Castle, etc.), and fuzzy parameters (warmth, loneliness, etc.) may be set as keywords. is there. Normally, these keywords are used for database search, content search on the Internet, and the like, and the setting is manually set and input by an operator from an operation input unit such as a keyboard, or automatically set and input by a robot agent. Or automatically set by image / voice / character recognition processing.

In this embodiment, an example of processing for adding position information (particularly, original position information) when a keyword is added to content information in this way will be described.

First, as shown in FIG. 5, upon input of the content 40, the digitization processing unit 51 converts the substantial content into digital data, and generates the substantial data 41 relating to the content 40. Then, in the keyword setting unit 52, the keyword 43 for search is added to the entity data 41, and the entity data with keyword 42 is generated.
The keyword setting unit 52 sets the keyword manually or automatically by the above-described method. A plurality of keywords may be set here.

Then, the position information adding section 10 obtains position information based on the keyword and adds it to the content information. Specifically, in the position information adding unit 10, the keyword 4
By extracting only 3 and performing character recognition or the like, a geographic keyword is extracted from a plurality of keywords. Then, by referring to the location information DB 110 based on the extracted geographic keywords, the location information (latitude, longitude, altitude, etc.) corresponding to the content 40 is obtained and added as original location information. When a plurality of geographical keywords are extracted, position information is obtained for each of them, and thus the plurality of pieces of position information are added.

As a result, as shown in FIG.
1, the content information 30 including the keyword 33 and the entity data 32 can be generated.

In general, a keyword is set as a word related to the content of the content. By performing the processing as described above, the position information related to the content of the content is changed to the original position information.
It will be added to 0. Therefore, for example, when a search keyword is attached to each content and a plurality of contents are managed in a database or the like, the position information can be specified from the keyword, so that each content can be identified. , Position information can be added more efficiently.

Note that the current position information is the first
As in the first embodiment, the current position information stored in the memory 120 in advance may be read out and added to the content information 30. The information may be added based on the current position information detected by the means.

Each process (the digitizing section 51, the keyword setting section 52, and the position information adding section 10) shown in this embodiment is configured to be separated in stages and processed by different computers. Of course, it may be possible.

<3. Third Embodiment> Next, a third embodiment will be described. Here, too, the computer 10 in the geographic information system 1 of the first embodiment is described.
0, another embodiment of a mechanism for adding position information will be described.

FIG. 6 is a diagram showing the configuration of the computer 100. Similar to the first embodiment, the computer 100 includes a position information adding unit 10, a position information DB 110, and a memory 120.
Are configured to function as the recognition processing unit 11 and the position specifying unit 12.

In this embodiment, the recognition processing section 11 further includes an address recognition section 11a and a postal code recognition section 1.
1b, is configured to function as a telephone number recognition unit 11c. When the entity data 41 of the content is input, information that can specify a position such as an address, a postal code, and a telephone number from the content of the content is obtained. Extract.

When the content is an image, the address recognizing unit 11a performs image recognition processing on the image to extract character information relating to the address from the image. For example, an electric pole or the like may have an address or the like at that position. If such an electric pole is photographed in an image, characters or the like relating to the address portion may be extracted by performing image recognition or the like. The address at which the image was captured is specified by referring to an address database or the like.
When the content is a sentence, information on the address can be extracted and specified by performing character recognition or the like. If the content is music, voice, etc., information about the address is extracted by performing voice recognition, etc.
Can be identified.

The zip code recognition unit 11b extracts and specifies information on zip codes by performing image recognition and the like according to the contents of the contents, similarly to the address recognition unit 11a. For example, if a seven-digit number is obtained as a result of image recognition, a postal code database or the like is referred to based on the seven-digit number, and if a corresponding postal code exists, the seven-digit number is changed. It can be specified as a postal code.

The telephone number recognition unit 11c also performs
By performing image recognition or the like in accordance with the contents of the content, information on the telephone number is extracted, and the area code, the local code, and the like are specified. For example, if a 10-digit number is obtained as a result of image recognition, a database of area code and local area code is referred to based on the 10-digit number. Can be specified as a telephone number.

Then, the position specifying unit 12 functions,
The location information corresponding to the specified address, postal code, and telephone number is extracted from the location information DB 110 and added to the entity data 32 as the original location information of the content,
The content information 30 is generated. That is, in this case, position information on an arbitrary address, postal code, and telephone number is registered in the position information DB 110.

The current position information added to the content information 30 may be the current position information stored in the memory 120, as in the above-described embodiments.
It is current position information detected by position detecting means such as GPS.

As described above, the address, the address,
By extracting information that can specify the location, such as postal code and telephone number, and adding location information,
It is possible to add position information suitable for the content.

By applying the above technique, the position related to the contents of the content is specified, and it is clear that the original position information of the position information can be added. It is possible to add current position information by a similar technique. For example, a vehicle is equipped with a camera, and an external scene is photographed at any time while the vehicle is running. The image obtained by the camera is used for address recognition unit 11a, postal code recognition unit 11b, telephone number recognition. If the unit 11c functions, it is possible to specify the current position where the car is running.

It is desirable that the position information added to the content information is originally information that can specify one point (0-dimensional) on the map. There is also a case where information serving as a basis for specifying position information cannot be obtained, or a case where information for specifying one point cannot be obtained.

Therefore, in such a case, the position information is set to 2
A position may be specified in an area having a three-dimensional or three-dimensional spatial spread, and the position specifying unit 12 may add such position information.

For example, the computer 100 having the configuration shown in FIG.
Even if the address recognizing unit 11a specifies a town name, a country name, and the like, one point to be displayed on the map cannot be specified. Therefore, the shape data of the entire town or country is added to the position information, and the longitude, latitude, and altitude are added. And the like, coordinates of representative positions (such as locations of government offices and capitals) included in the town or country may be added.

When the accuracy of the position information detected by the position detecting means such as GPS is degraded in the current position information or the like, one point (reference point) such as latitude and longitude having the highest probability is used. In addition to adding position information, a radius from a reference point and the like may be added as accuracy information so that concentric displays such as ± 100 m, ± 1 km, and ± 10 km centered on the position can be performed. It may be. If the reproducing unit 20 of the computer 200 on the receiving side is configured to be able to display the display colors differently according to such accuracy information, concentric accuracy displays with different display colors can be performed. , It is possible to estimate the approximate position of the current position of the content.

However, the present invention is not limited to this, and the content is stored in an arbitrary medium. It can also be applied when transported by. In other words, when the medium storing the content is transported, the location information is additionally stored in the medium at the relay point in the transport route, and when the transport is completed, the location information is read from the medium and the map is read. By displaying the information in association with the above, it is possible to easily grasp the route through which the medium (that is, the content) has been conveyed.

In the above description, the case where both the original position information and the current position information are set as the position information has been exemplified. However, depending on the field of use of the geographic information system 1 according to the present invention, any one of them is used. Since the purpose can be achieved simply by adding the position information, in such a case, one of the original position information and the current position information is added to the content information according to the purpose. May be configured.
