Abstract

PURPOSE: To shorten the time for work by dividing a character string into blocks in the case of inputting the character string, setting the numbers of respective blocks, plotting addresses at the positions of addresses designated by a coordinate designating means and afterwards, inputting block numbers required for the plotted addresses sequentially until the last set number. CONSTITUTION: The master number and slave number of the address to be inputted are set by an input means (step S12) and afterwards, when the position of an address is designated (step S14), that address is plotted at the position designated by the coordinate designating means (step S15). Besides, when the position of the address is not designated (step S14) and the slave number is reset by the input means (step S16), the new value is defined as the value of the slave number (step S17) and afterwards, the designation of the address position is waited for. Further, when all the processing results for designating the addresses of the master and slave numbers are 'N', processing is stopped by a stopping means (step S20).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character string inputting method in a device which has a drawing process, reads image data from a scanner, and recognizes a drawing.

[0002]

2. Description of the Related Art There are two types of devices for recognizing drawings input from a scanner, a fully automatic type and a partially automatic type (hereinafter referred to as a semi-automatic type). A fully automatic recognition device is one in which the device automatically recognizes an input drawing and no operator intervenes until the recognition is completed. Drawings drawn so that the drawing recognition device can recognize correctly,
There is no problem even if it is recognized by a fully automatic recognition device,
When the drawings other than the above are recognized by the fully automatic recognition device, there is a problem that erroneous recognition occurs and it takes time for the operator to correct the recognition after recognition. On the other hand, the semi-automatic drawing recognition apparatus has an advantage that an operator recognizes an input drawing in an interactive manner, so that erroneous recognition, that is, a correction amount is reduced, resulting in a shorter input time.

In the case of inputting a character string using the semi-automatic drawing recognition apparatus having the above-mentioned advantages, efficient recognition of the character string becomes possible by selectively using the recognition process and the drawing process depending on the quality of the drawing. . Therefore, in a neat and clean drawing, the operator specifies the elements forming the character string (character) and performs the recognition process. However, in a complicated drawing, first, a character string on the drawing is drawn. For example, in a general-purpose drawing recognition device,
The image data input by the scanner is converted into vector data representing a figure. The operator properly uses recognition and drawing as shown in FIG. 4 depending on the quality of the drawing.

In FIG. 4, when a character string is input in step S1, it is first determined in step S1 whether the quality of the drawing is good.
Judge with 2. If the result of determination in step S2 is good “Y”, processing in step S3 is performed. In step S3, the operator selects a vector forming the character string from the drawing. After the processing of step S3, the operator selects the function of recognizing the character string in step S4. Then, in the process of step S5, the device recognizes it as a character string and ends the process.

On the other hand, when the quality is "N" which is not good in the processing of the step S2, the operator inputs the characters constituting the character string in step S6. After that, the operator specifies the position of the character string in step S7, and the apparatus draws the character string input in step S8, and then the process ends.

[0006]

When the drawings are recognized semi-automatically by the above-mentioned method, the drawings are complicated like the land use drawing shown in FIG. 5, and a large number of character strings representing the addresses exist. , When drawing and inputting that character string, it becomes necessary to input each character, and in addition to the above character string in the actual address, "a", "b",
Since there are non-numeric characters such as “C”, “A”, and “B”, there is a problem that the burden on the operator increases more and more.

The present invention has been made in view of the above circumstances, and provides a character string input method in a drawing recognition device which can save the labor of inputting each address and can shorten the working time. With the goal.

[0008]

Means and Actions for Solving the Problems
In order to achieve the above object, the first aspect of the present invention specifies the position of an address by the coordinate specifying means on the land use drawing read by the scanner, and inputs the character string representing the address at the position by the input means. Then, in the drawing recognition device for managing and editing the drawing by the managing means, when the character string is inputted by the input means, the character string is divided into two or more blocks and the number of each block is set. It is characterized in that an address is drawn at a position of an address designated by the coordinate designating means, and then a block number required for the drawn address is set by the input means until it is no longer set.

The second aspect of the invention is characterized in that the block number is divided into a high-order digit and a low-order digit and input respectively.

According to a third aspect of the invention, a conversion table in which characters corresponding to a special character string are converted and displayed is stored in advance in the management means, and the position of the address designated when the special character string is input. It is characterized in that the characters converted in the conversion table are displayed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram of a drawing recognition apparatus. In FIG. 1, 11 is a scanner for reading a drawing,
The drawing read by the scanner 11 is managed and edited by the management means 12 for managing and editing the drawing. Reference numeral 13 is an input means for inputting a character string of an address, and the character string of the address inputted by the input means 13 is supplied to the management means 12. The character string of the address inputted by the input means 13 is written at the position of the address designated by the coordinate designating means 14. 15
Is a stopping means for issuing a command to stop the processing of each of the above means.

Next, an example of inputting an address in the drawing recognition apparatus will be described with reference to the first embodiment. 2 is a processing flowchart showing the first embodiment of the present invention. In FIG. 2, mm of a character string (mm-nn) representing a lot number is called a parent number and nn is called a child number. In step S11, address input processing is first started. By this processing, step S12
The parent number mm and the child number nn of the address to be input at are set by the input means 13 shown in FIG. For example, setting the parent number and child number mm-nn [Ret] is 100-
It becomes 20 [Ret].

After the above processing, it is determined in step S13 whether a number has been set. If nothing is set, "N", the processing ends. In the case of the set "Y", the process of step S14 is performed by the coordinate designating means 14 shown in FIG. In the step S14, when the position of the address is designated by the coordinate designating means "Y", the address is plotted at the designated position in the step S15. At this time, in step S15, the value of the child number nn is incremented by 1 (nn = nn + 1), and then the process returns to step S14. If "N" where the position of the address is not designated in the process of step S14, and "Y" when the child number nn is reset by the input means 13 in the process of step S16, a new value is set in step S17. After setting the value of the child number, the process returns to step S14. For example, the child number setting nn [Ret] is 30 by inputting a numerical value.
[Ret].

After that, step S14 and step S16
If the result is "N", the process of step S18 is performed. In step S18, the parent number m is input by the input means 13.
It is judged whether m is reset, and if it is reset "Y",
In the process of step S19, the parent number mm and the child number nn are reset, the new value is set as the address value, and the process returns to step S14. For example, setting of parent number and child number mm-nn
[Ret] becomes 200-10 [Ret] by inputting a numerical value.

After that, the steps S14 and S are performed again.
16 and step S18 are carried out, and if all are "N", the processing is stopped by the stopping means 15 shown in FIG.
This processing is step S20, and this step S20
If the processing is not terminated at step "N", step S14 is executed again.
If it is "Y", the processing is performed from step S
It is performed from 12 processes.

The above-mentioned first embodiment relates to a function of semi-automatically inputting an address, and by using this function, it becomes possible for an operator to save the labor of inputting each address one by one.

Next, a second embodiment will be described with reference to FIG. Second
In the embodiment, steps S14 and S1 of the first embodiment are used.
As shown in FIG. 3, the function of converting an input character into a keyword is added to the processes of step 7 and step S19, and shown as step S21, step S22, and step S23, respectively. For this reason, in this second embodiment, the management means 12 is provided with a memory for storing a conversion pattern when a character string is input in advance. For example, when the characters "a", "b", ... "To", "to" are present in the address, the correspondence between the input character and the conversion result is stored as shown in the following table.

[0018]

[Table 1]

In the case of step S21 in which the child number is incremented by one, the result of this conversion is that the characters are changed in the order of a → b → c → d → e → h → t → a ... Multiple conversion patterns for this input character can be specified. For example, the following table may be added to the patterns in the above table.

[0020]

[Table 2]

In the second embodiment having the conversion table set as described above, the steps which perform the same processing as in the first embodiment are designated by the same reference numerals. First, when a character is input to the child number in step S12, for example, m is input according to the conversion rule.
m-ss [Ret] → (example) 100-i [Ret] is converted to “100-a”. The parent number mm does not have to be a numerical value.

Next, when a number is set in step S13,
The processing is step S14, and when the coordinates are designated by the coordinate designating means 14, the processing of step S21 is performed. In step S21, when the position of the address is specified, the address is drawn at the specified position and the value of the child number is set to 1
If the child number is a character, the child number is set as the next character in the conversion table and the process returns to step S14.

In the case of "N" in step S14, the process of step S16 is performed, and when the child number nn is reset by the input means 13, the same process as in the first embodiment is carried out, but the character ss is added to the child number. If set, the character obtained from the conversion table is used as the child number, and the process returns to step S14. As an example, ss [Ret] → (example) ni [Ret] becomes “d”.

As in the first embodiment, step S14,
If "N" in step S16, the process of step S18 is performed. When the parent number mm and the child number nn are reset in step S18, the same process as in the first embodiment is performed, but when the child number is set to the character ss, the character obtained by the conversion table is used as the child number in the step S18. It returns to the process of S14. For example, mm-ss [Ret] → (example) 200-to [R
et] becomes “200-to”. Then, step S2
The process of 0 is performed.

[0025]

As described above, according to the present invention,
With the function to automatically input a part of the address and the function to convert the input characters into keywords, the operator can save the trouble of inputting each address including the characters. The working time can be shortened.
