[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a method and a system for recording information added by handwriting or the like on a sheet on which various information recorded in a database is printed, in the database.

[0002]

Generally, various types of information such as maps and drawings recorded in a database of a computer are printed as needed and used for various purposes.

For example, in the case of a field survey in a specific area,
A map of the area to be surveyed is read from a computer database and printed, and a surveyor carries the printed map to the site and writes the survey results and the like.

[0004] In a case where information added later to such printed information is recorded in a computer to newly create a database, conventionally, an operator writes the information on a paper such as a printed map. Information to be read, and information to correspond to the printed information, for example, if the printed information is a map, along with location information such as the address of the location where the writing is performed and the latitude and longitude, The method of inputting it to a computer is used.

However, in such a conventional method, when inputting to a computer, the operator needs to read additional information and related information for associating the additional information with print information. In addition, there is a problem that the input operation to the computer is very troublesome.

[0006] The present invention has been made to solve the conventional problems in data processing of information added to printed information as described above. That is, a first object of the present invention is to provide a recording method of additional information which can easily perform data processing of information added later to printed information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an example in which the present invention is applied to a case where various kinds of information such as regional information added by handwriting or the like to a printed map are recorded in a database of a computer. In FIG. 1, the microcomputer 1 is set up with an electronic map application application or the like so that desired map data can be searched and displayed from a database constructed in advance. The data is output to the printer 2 and printed.

The search for the map data is performed not only on a database recorded on a recording medium such as a hard disk connected to the microcomputer 1 but also via the Internet.

For example, when an investigator conducts an investigation while carrying a map of the investigation area on site in order to collect regional information, the microcomputer 1 uses a database recorded on a hard disk or the like to execute the investigation. Is read out and printed by the printer 2.

The paper P on which the map M is printed by the map data read from the database is further provided.
The code C indicating the print range of the map M is printed. The code C collects information indicating the print range and contents of the map M such as coordinate values based on latitude and longitude, place names, facility names (eg, department stores, movie theaters, stations, supermarkets, etc.), map classifications, and scales. It is created by encoding. And this encoding is XML, HTM
It is performed based on L, vCard or a coding system similar thereto, and a technique such as compression coding is used as needed. The code C is printed on the paper P by a method capable of mechanically reading, for example, a numeric string, a bar code, a two-dimensional bar code, a magnetic recording, or the like.

The surveyor H holds the map M and the paper P on which the code C is printed and goes to the area indicated on the map M, and conducts a predetermined survey (for example, a survey of the position of a manhole).
I do.

Then, as shown in an enlarged manner in FIG. 2, the investigator H writes the survey result (for example, the position of the manhole m) on the survey point on the map M or a means similar thereto, such as a bar code or the like. Fill in by means such as pasting a sticker showing a predetermined symbol.

In the blank portion N of the sheet P, additional items related to the investigation, such as the name of the investigator, the date and time when the investigation was performed, and findings on the investigation, are entered. As above,
The paper P 'on which the survey result is written is taken out and then mechanically read by the optical reader 3 and input to the microcomputer 1.

The microcomputer 1 obtains, from the image information indicating the read image of the sheet P ′ on which the survey result has been written,
By subtracting the information of the printed map M by the following method, additional information for additional writing indicating the investigation result is extracted, and the extracted additional information is converted into an electronic document and recorded on a predetermined recording medium.

FIG. 3 is a flowchart showing a procedure for recording additional information of the sheet P 'in the microcomputer 1. FIG.
Is shown in FIG.

In FIG. 3, the microcomputer 1 reads a sheet P ′ read by the optical reading device 3.
From the image of the code C included in the image B, information such as coordinates indicating the print range of the map M and a scale is obtained by an OCR method (step s1).

Then, based on the obtained information indicating the print range of the map M, the map data corresponding to the map M is retrieved from the database connected to the microcomputer 1, and the map data is read out ( Steps
2).

Next, as shown in FIG. 4, the image B of the map data in the database is subtracted from the image A of the sheet P 'which has been read previously, and the additional information F written on the sheet P' is subtracted. Only the data is extracted (step s3).

Further, from the additional information F extracted in this manner, a map of a survey result is obtained based on information such as coordinates and a scale indicating a print range of the map M read by the code C read earlier. The coordinates of the entry position on M are calculated (step s4).

The calculation of the coordinates of the entry position on the map M based on the survey result is performed, for example, by calculating the coordinates indicated by the latitude and longitude of an arbitrary position on the map M included in the code C.
This is performed by calculating the distance to the entry position in consideration of the scale of the map M included in the code C. The coordinates of the entry position of this survey result on the map M are represented by the code C
Is also specified by the area name or facility name in the map M included in the map.

As described above, incidental matters such as the survey result and the survey date and time entered in the extracted paper P ′ are as follows.
The survey results are electronically documented together with point information indicating the survey location (coordinate values based on the latitude and longitude of the survey point, specific places composed of regional names, classifications, etc., facility names, etc.) and recorded on a hard disk It is recorded on the medium (step s5).

The survey information and the like accumulated in the recording medium in this way are, for example, when examining the statistics for each area or the distribution of a specific item, the spot information is recorded together with the survey information on the recording medium. This makes it possible to widely use it for creating a database for various survey-related operations, for example, by reading out and summarizing survey information of a specific area based on this point information.

In the above description, an example has been described in which additional information such as a survey result written on a printed map is extracted separately from map information and recorded on a recording medium. The method for recording additional information according to the present invention may include, besides the above, for example, reading out a design drawing of a factory facility, a plant, and piping from a database and printing the design drawing, and modifying the printed design drawing and piping drawing at the site. When handwritten information is entered, and additional information such as design changes are recorded in a database later, the information added later by handwriting or the like to the required printed information is extracted from the original information. The present invention can be applied to any case where recording is performed on a recording medium.
