Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a system for acquiring a specific position on paper with an electronic pen and converting it into electronic information, and in particular, acquiring a position coordinate on a map and converting it into electronic information, and converting the converted coordinate information into another information. The present invention relates to a map information processing system used in an apparatus.
[0002]
[Prior art]
Conventionally, a number of methods have been considered in order to detect and convert two-dimensional position information of a specific point on a map printed on paper and output it as map coordinates. A sheet with coordinates is fixed on the map to read the paper coordinates of an arbitrary point, or the map is divided into several sections, and the position in the entire map is determined from the section number and the position in the section. There is a method to identify. To input map information, a transparent panel or tablet is used, and information is acquired from the map by button operation or pen input.
[0003]
For example, in the apparatus disclosed in Japanese Patent Laid-Open No. 9-138131, map coordinates are acquired by fixing a transparent tablet on a map in which coordinates are set, and specifying and inputting coordinates on a sheet with a cursor.
Another example of the map information acquisition method is the use of GIS (Geographic Information System). In GIS, it is possible to directly input data on a map in the form of electronic information, reproduce the electronic map on a computer, and perform operations such as database construction and analysis using the map information.

[Problems to be solved by the invention]
In order to use the paper coordinates read from the map by inputting it to another device, it is necessary to convert the paper coordinates on the map into geographical coordinates. In the past, in order to use a figure or position on a paper map in GIS, the geographical coordinates had to be entered directly on the GIS. However, in this case, complicated button operations are often required for input, and geographic information must also be input directly in the form of electronic information. Alternatively, it is necessary to input the handwritten figure and position information on the paper map as they are and then convert the coordinates to geographic coordinates. In that case, it is often unsuitable for carrying because of the size and weight of the input device itself, and the characteristics of paper are superior in terms of ease of input, storage stability, softness to bending, etc. I can say that. In addition, since coordinate information is not held in the map itself, it is often necessary to align the input device with the map, or to change the screen, display an enlarged image, and input coordinates. Furthermore, in the case of using a map of a plurality of sections, the operation is often very complicated in the conventional technology, for example, data must be connected. In order to find an arbitrary point while comparing multiple maps or maps with different scales, it is faster to enter geographical coordinates using a paper map that does not require a response from the map. is there. When specifying a region, it is often necessary to indicate the location by a location on the map rather than specifying the location from the address.
[0006]
The present invention provides a method for converting paper coordinates on a paper map into geographical coordinates and transmitting them to another device by taking advantage of the paper map in order to compensate for the drawbacks of the conventional device as described above. It is aimed.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has the following configuration.
In a map information processing system comprising paper on which position information is recorded in a dot pattern, and an electronic pen that acquires the position information by reading the dot pattern and converts it into electronically readable position information, the geographical coordinates on the paper A map printed with a dot pattern associated with the map, and paper identification information for identifying the map on the map, and converting the position information of the paper acquired by the electronic pen into coordinates on the electronic map A map information processing system comprising means for performing
[0008]
More specifically, in the present invention, the electronic map 1 is cut out and printed on the electronic paper 2 according to the scale. As shown in FIG. 1, the electronic paper number 3 and the electronic map number 4, the electronic paper Are matched with the geographical coordinates 6 of the map 7 printed on the electronic paper and the geographical coordinates 6 of the map 7 printed on the electronic paper.
One feature of the present invention is that information that associates the electronic paper number with the map on the electronic paper is stored and held in a database.
In the above description, the paper coordinates are read from the map on the electronic paper printed by associating the dot pattern with the map coordinates using the electronic pen. One feature is that paper coordinates can be obtained as geographic coordinates by using a database that associates the paper coordinates on the electronic paper with the geographic coordinates of the electronic map.
In the above, the acquired paper coordinates and paper ID can be individually transmitted to the processing device. Another feature is that the data transmitted at the same time can be acquired as original data without being confused at the transmission destination.
A method of converting coordinates on a map acquired with an electronic pen into actual latitude and longitude can be realized as conversion between XY coordinates and plane rectangular coordinates. In this case, the acquired paper ID and map number are associated with each other, and absolute coordinates X and Y serving as reference points on the page are obtained from the map number. Next, the absolute coordinates of the position designated by the pen are obtained in consideration of the reference point on the map book and the offset. The conversion from absolute coordinates to latitude / longitude can be realized using a normal method.
Thereby, the coordinate on the map acquired with the electronic pen can be converted into actual latitude and longitude.
It is also possible to obtain the latitude / longitude directly from the paper ID and the XY coordinates of the map.
[0009]
In addition, by eliminating the margin of the map book and setting the offset to 0, a map database in which the XY coordinates of the map and the XY coordinates of the paper are matched can be created in advance.
In the above description, the conversion to latitude and longitude is performed using a world geodetic system (WGS). However, geographical coordinates converted into UTM (universal transverse mercator's projection) coordinates, plane rectangular coordinates, or the like may be used.
When processing paper coordinates acquired from a map via a network, a function box 25 printed on a map or other electronic paper on which a dot pattern is printed is used. By distributing the data transfer destination and checking the transmission box 26 for transmission, one data can be used by a plurality of applications. In addition, the function box for sorting the transmission destinations can be used without being polluted even if it is used repeatedly by adopting a method in which used ones are peeled off or a method in which the destinations are sequentially turned from the top.
[0010]
In order to read not only the paper coordinates from the map 21 printed on the electronic paper but also the information accompanying the geographic information or the information to be added for convenience, the same page as the map or other Characters / graphics written in the memo field 27 printed on a page or a separate sheet can be transmitted as additional information. In addition, the memo column has a feature that it can be used without being polluted even if it is used repeatedly by taking a method of peeling off used ones or a method of turning from the top.
Map data in one-to-one correspondence with each electronic pen and divide it into multiple layers, or use the function box to identify each input person and divide the map data layer for each input person. It is possible to easily manage the input data and update data of the map. Another feature is that a user's update history can be managed by setting a time stamp of map input / update data in units of layers.
When the reuse of the map is considered, the map itself is made disposable by creating a plurality of electronic papers having exactly the same dot pattern, map information, and corresponding relationship. Alternatively, if a transparent or highly transparent sheet is placed on the map and an arbitrary position on the map is designated with a pen from the top, the sheet can be reused by exchanging the sheet without soiling the map. In addition, when inputting data using a pen from a map, not only normal black ink, but also the use of fluorescent paint ink or ink that disappears after a certain period of time, and ink that can be erased by correction means such as an eraser. Use or input means to trace the position on the map without using ink.
One feature is that new data and updated data can be shared among a plurality of terminals from a plurality of terminal devices by placing a shared server that holds the processed map information on the network.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
First, the simplest and basic system configuration of the present invention will be described.
As shown in FIG. 3, the system itself includes a map, an electronic pen, and a PC written on electronic paper on which a dot pattern is printed. A map coordinate conversion database that converts received paper coordinates into geographic coordinates, a map database that stores the converted geographic coordinates and various map information, and an application that uses the map information are incorporated in the PC. . A flowchart showing the flow of the processing with the electronic pen and the processing program with the PC 33 is as shown in FIG.
First, when the user designates a specific position on the map 32 with the electronic pen 31, information for specifying the paper coordinates and the map is read from the dot pattern. (S11)
When the transmission box is checked and a transmission signal is sent, the read paper coordinates are transmitted to the PC 33 (S12).
The paper coordinates are converted into geographic coordinates by the map coordinate conversion database and then used by the application (S13).
One of the methods for obtaining the position information of the part pointed with a pen on paper is a technique described in International Application No. PCT / SE00 / 01897 (WO01 / 26033A1). In this technology, the encoding pattern of the position is given to the dot on the electronic paper, and the character or figure written on the electronic paper using the electronic pen is read from the encoding pattern of the dot. Is stored and transmitted as dot pattern vector information. In this embodiment, the electronic pen or the electronic paper will be described as an example. It is not necessarily limited to that example.
Next, an example of a method for converting paper coordinates (XY coordinates) read from a map printed on electronic paper into geographical coordinates will be described.
[0012]
FIG. 2 shows one page on the map book on which a map is printed. The map is actually printed in the portion excluding the margin and the function box area 23 in the lower stage. However, dot patterns are also printed for margins and function box areas.
The map corresponding to which map can be identified by the paper ID 22, and the latitude / longitude can be obtained from the paper ID and the X coordinate 28a and the Y coordinate 28b with the origin at the upper left of the page. Using a function F
[X _g , Y _g ] = F (PP _ID , X _m , Y _m )
Can be calculated.
However,
PP _ID : Paper ID
X _m : X coordinate on the map book
Y _m : Y coordinate on the map book
X _g :latitude
Y _g :longitude
And Here, the function F performs the following calculation.
Since there is no ID for identifying the page in the map book, it is necessary to associate the paper ID with the map number on the map. This is determined by the data table 101. Furthermore, the absolute coordinates X and Y at the upper left of the page can be obtained from the map number based on the information in the map database 102. In addition, the coordinates (X _m , Y _m ) And offset (X _off , Y _off ) Considering 28c and 28d, the absolute coordinates of the position specified with the pen (X + X _m -X _off , Y + Y _m -Y _off ) Is obtained.
Conversion from absolute coordinates to latitude / longitude is generally performed widely, and the function H _g, Y _g ] = H (X + X _m -X _off , Y + Y _m -Y _off )
Can be converted into latitude and longitude on the map.
There is also a method for obtaining the latitude and longitude directly from the paper ID and the XY coordinates of the map. _g, Y _g ] = I (index, X _m -X _off , Y _m -Y _off )
You may obtain | require by calculation of.
In the above, conversion to latitude and longitude is performed using WGS, but geographical coordinates converted to UTM coordinates, plane rectangular coordinates, etc. may be used.
[0013]
As a specific example using the above system, an example in which a paper map is used as an input device for navigation in combination with an existing car navigation system will be described in detail with reference to the embodiments shown in FIGS.
Here, among navigation systems equipped with a map book and a computer device, the car navigation system is used by the operator to input destinations, zoom in / out of maps, road congestion, etc. using a map book printed on electronic paper. An example of a method for displaying tourist information on a specific map will be described as an embodiment.
In FIG. 4, the car navigation system 41 includes a car navigation terminal 42, a map book 32, and an electronic pen 31. The car navigation terminal 42 is a computer device that includes a conversion unit that converts a paper ID and XY coordinates into latitude / longitude corresponding to a reduced scale in a car navigation terminal that is generally sold. The map book 32 accurately aligns the paper ID and XY coordinates of the electronic paper and the latitude and longitude of the map on the electronic paper on which the dot pattern for specifying the writing position described in the prior art is printed. This is a multi-page map book. The electronic pen 31 is an electronic pen having the same components as the electronic pen described in the related art.
[0014]
In the map book of FIG. 5, different dot patterns are printed on each page. By pointing to a specific position with a pen, it is possible to determine which XY coordinate of which page.
Further, it is conceivable that a special box area 53 for designating a navigation function is formed on each page and used for operating the car navigation system. All or part of these special box functions can be arranged on a specific page such as a cover without printing on each page if necessary. The destination setting box 53a is a box for designating that a specific portion of the corresponding page is selected as the destination. The map display box 53b is a box for designating display of the map of the corresponding page. The transmission box 54 is a box for transmitting the designated function by the car navigation system.

The control unit 68 controls input / output and processing of the entire car navigation terminal. The navigation processing function of the control unit receives the paper ID and XY coordinates received from the pen 31 via the pen interface 65a, and is specified by the function determination unit 67 together with the latitude / longitude information specified by the coordinate conversion processing unit 66. The function is discriminated, display of map information, specific information, and the like is displayed on the display 64b, and a destination is set.
The function determining unit 67 determines the function designated by the user from the paper ID and the XY coordinates. The coordinate conversion unit 66 performs conversion processing from the paper ID and XY coordinates to latitude / longitude using the map database 63a.
The pen interface 65a is a communication device that receives data transmitted from the pen.
The display device 64b is a display for displaying information processed by the car navigation terminal 42 and information such as a map.
The voice processing unit 69 a is a speaker that outputs information processed by the car navigation terminal 42, an operation explanation to the user, or a microphone for inputting voice to the car navigation terminal 42.
[0015]
The above-described car navigation terminal 42 can also be realized by installing devices and programs such as a pen communication device, a coordinate conversion processing unit 66 of a map book, and a function determination unit 67 on a commercially available car navigation terminal. is there.
A specific method of using the car navigation system 41 in this embodiment will be described.
A case where the user inputs a destination using the car navigation system 41 will be described as an example.
The user searches the map book 32 for a page where the destination exists. At this time, the user may freely select which scale page of the map is selected. (Step 61)
The user uses the electronic pen 31 to specify a specific position of the destination among the pages with the destination. As a method of designating, the destination is circled or touched. (Step 62)
The user checks the destination setting box 53. (Step 63)
The user checks the transmission box 54. (Step 64)
When the transmission box 54 is checked, the paper ID and XY coordinate data are transmitted from the electronic pen 31 to the pen interface 65a. (Step 65)
When the control unit 68 receives data from the pen interface 65a, the control unit 68 uses the function determination unit 67 to determine the selected function. In this example, it is determined that the destination setting function. (Step 66)
The control unit 68 converts the received paper ID and XY coordinate data into latitude and longitude using the map conversion database 63b. (Step 67)
The position corresponding to the converted latitude / longitude is set as the destination. (Step 68)
At the same time, a map centered on the destination is acquired from the map database 63a and displayed on the display 64b. (Step 69)
End (step 70)
An example in which a system constructed only by the electronic pen, electronic paper, and PC is applied via a network is also conceivable. A system (Fig. 7) that sends input information from the pen to the specified application for processing on an open network, such as the Internet, and is closed so that it can be applied to governments and companies in consideration of security. It is a system (FIGS. 8, 9, and 10) implemented in a domain. The structure of each system is as follows. In addition, in the case of such a system on the network, it is also possible to communicate with other information terminals on the network, transmit / receive information, and share information. Moreover, since the data can be updated immediately, the latest information can always be obtained.
(1) When using an application distribution type server in an open network.
As shown in FIG. 7, in addition to the system shown in FIG. 3, an application distribution type server 73 for identifying a service application server to be used from a paper ID and paper coordinates (the server includes all the paper IDs and the locations of the corresponding applications) The application server 75 that communicates with the pen and provides various services from the paper ID and paper coordinates, and converts the paper ID and paper coordinates to geographic coordinates on the map. The map coordinate conversion database 76 is configured.
[0016]
FIG. 16 is a flowchart showing the flow of program processing in an open network including the hardware shown in FIG.
The user designates a specific position on the paper map 32 with the electronic pen 31, checks the transmission box, and sends a transmission signal. (S21)
In response to the transmission signal, coordinates input from a paper map are transmitted to a relay device 33 such as a mobile phone or a personal computer through wireless communication. (S22)
The paper coordinates are further transmitted to the application distribution type server 73 through the Internet 72. (S23)
The server stores all the paper IDs and the locations (URLs) of the applications corresponding to them, and detects the URL information of the application that matches the transmitted paper ID. (S24)
The URL information is sent back to the electronic pen 31 again. (S25)
The pen transmits the input paper coordinates themselves to the application server 75 via the relay device 71, and acquires geographical coordinates.
Upon receiving the returned URL information, the converted latitude / longitude information is transmitted to the corresponding application 77, and the designated type of processing is performed. (S26, S27)
The following specific examples can be considered using such an open network.
[0017]
Fill in the map book of the schedule book with map information and attribute data such as shops and buildings, and check the function box for e-mail and fax to send data to the specified address and phone number in the form of e-mail or fax Can be sent.
[0018]
In creating a travel journal, when a travel locus or information on each point is written on a map on electronic paper, it is transmitted to the network through a relay device, and the record on the Web is immediately updated.
Of these, the use in the schedule book will be taken up and explained in detail next.
[0019]
As shown in FIG. 8, the electronic pen 31, the map book 32, the mobile phone as the relay device 71, the communication network 72, and the application distribution type server 73 are configured, and e-mail and FAX are set as data transmission destinations. The Examples of usage are shown below. Here, an example in which information about a newly found store is transmitted using electronic mail will be given.
First, as shown in the map book of FIG. 9, the function box 93 a for designating the location information of the map is checked, and the location of the store is marked on the map 92. (Step 81)
The function box 93c for designating the memo column 95 is checked, and information such as impressions, product prices, and other stores is entered in the memo column 95. (Step 82)
Enter the destination e-mail address in the designated field 96c and check the e-mail function box 96a. If you want to send a fax, enter the fax number in the designated field and check the fax function box 96b. (Step 83)
When the entry of necessary items is completed, the transmission box 94 is checked. (Step 84)
When the transmission box is checked, the pen ID and the paper ID are transmitted from the electronic pen 31 to the application distribution type server 73 via the relay device 71. (Step 85)
The application distribution server 73 determines the corresponding application from the pen ID and paper ID, and returns the URL information to the electronic pen again. Then, the input data itself is sent to the returned URL application. (Step 86)
Among the transmitted data, the paper coordinates are converted into geographic coordinates, and the entry in the memo field is converted into character data by encoding a handwritten character image. The converted data is transmitted as e-mail or FAX, respectively. (Step 87)
In some cases, a keyword search field is provided as a function box. It is also possible to adopt a system in which a keyword to be searched for is input to a keyword search field and transmitted to a search engine, and a matter related to the input keyword is returned by e-mail.
(2) When using an application distribution type server in a closed network.
It is basically the same as a system in an open network, but it can be said that it is a system that is performed in a closed domain, and that it is for organizations where confidentiality is important such as ministries, local governments, and companies. However, in this system, when the geographic coordinate conversion database 76 is included in the application distribution type server 73 as shown in FIG. 10, or when it is included in the application server 75 as shown in FIG. 11, the electronic pen 31 itself is shown in FIG. When performing geographic coordinate conversion, the following three types are conceivable.
[0020]
The following specific examples can be considered as examples of use in the closed domain.
If you want to record the location of an accident site or a newly built house, mark the location confirmed on the map book with an electronic pen. Attributes other than the location, for example, the situation of the accident site, the characteristics of the house, information on the surrounding area, etc. are written in a memo field set separately from the map. Which item is input is determined by checking a function box provided on the map book. Moreover, if the function box which designates that it is each input of a house location and an accident scene is used, the information regarding both can be input from one map. The memo field and function box can be used repeatedly by sticking a large number of papers with dot patterns printed on them and turning the used ones from the top in order or removing them. In the case of a system that processes data via a network, information read by the electronic pen is added to the database via the network. If a plurality of people can write information in one map book with different electronic pens, the information can be shared among the parties concerned by accessing this database.
Use the electronic pen to fill in a map on the electronic paper and fill in the location where you want to apply for complaints and reports regarding illegal dumping, bad odors, noise, etc. The residents themselves can easily apply.
Even when inputting basic forest plans and city plans, when local residents and staff enter any area, they can easily input plans using pen and paper. Conventionally, a complicated procedure of reading a drawing with a scanner device and converting it into a vector with a digitizer has been taken, but according to this method, it can be easily converted into geographic coordinates.
It can also be applied as a system that supports investigation activities at disaster sites. For example, if a fire breaks out, enter the data describing the survey status and site location in the memo field, specify the location on the map, and transmit it to the relevant fire department or police station. The latest damage situation can be shared among the parties concerned.
[0021]
The same method can be used when investigators of public institutions such as electric power, water, and gas investigate the location, usage status, and problems that have occurred, or facilities and buildings at multiple locations such as public telephones and public buildings. It can also be used for checking the failure status, repair status, and cleaning of toilets.
When used in field surveys, information on the survey target is written on the map when the survey target (animal, plant, mineral, etc.) is discovered and confirmed. It is possible to analyze the distribution area and habitat of the survey target, and at the same time to share information by adding information to the same area.
[0022]
Of the above application examples, the investigation support system at the disaster site will be taken up and described in detail with reference to FIGS.
As shown in FIG. 13, the system is composed of an electronic pen 31, a map book 32, a mobile phone as a relay device 71, a communication network, and an application distribution type server as in the use in a schedule book. The map book of FIG. 14 includes a map printed on electronic paper printed with a unique dot pattern described as an example in the prior art and several function boxes. Examples of usage are shown below.
First, when a disaster occurs, the function box 143a for recognizing that the fire department staff confirms the location of the site on the map book 141 is checked, and the location of the site is marked on the map 142. (Step 131)
Next, the function box 143b for designating a function to the memo column 144 is checked, and the field situation such as the degree of damage and the state of the injured is entered in the memo column. (Step 132)
After completing the necessary information, check the transmission box 145. (Step 133)
When the transmission box 145 is checked, the pen ID and the paper ID are transmitted from the electronic pen 31 through the relay device 71 to the application distribution type server. There are application distribution type servers of various organizations such as a fire department, a police station, and a city office, and the pen ID and paper ID are set to be transmitted to all servers. Since each server is connected to each other via a network, information can be shared immediately. (Step 134)
The corresponding business application 77 is discriminated from the pen ID and paper ID, and the URL information is returned to the electronic pen again. Then, the data itself is transmitted to the returned URL destination application 77. (Step 135)
Among the transmitted data, the paper coordinates are converted into geographic coordinates, and the entry in the memo field is converted into character data by encoding a handwritten character image. The converted data is variously processed by the application. (Step 136)
The three system configuration patterns and the respective application examples have been described above, but any of the application forms can be applied to any form of local, open network, and closed network. In any application, data can be transmitted over the network in real time to update the information, but the data is stored in the electronic pen itself and updated at the end. Is also possible.
[0023]
【The invention's effect】
As described above, according to the present invention, it is possible to easily acquire the position coordinates of a designated portion by simply pointing a specific point on the map on the electronic paper with the electronic pen, and to the electronic coordinate information of the map. Can be converted quickly. The converted coordinate information is immediately transmitted to the processing device, and can be applied to various systems and services while sharing information among the parties concerned.
