Abstract

PURPOSE:To easily re-edit a dictionary by changing the content of the dictionary which is used at the time of recognizing a character and a graphic from an observed pattern by means of a command from an editing terminal equipment through a control part and a dictionary editing part. CONSTITUTION:When a power source is turned on, the content of the recognition dictionary, a system program or the like are loaded from a data input output equipment 17 on a recognition device 14 and a storage device in the control part 11. The control part 11 executes the system program, whereby an observation part 12 transmits the character and the pattern which are read from a page space to the control part 11. The control part 11 displays in the editing terminal equipment 16 the result of having collated to the recognition dictionary 14 in a recognition part 13, and stores it in a data input output device 17. The dictionary editing part 15 and the editing terminal equipment 16 are connected always and if needed. When the content of the recognition dictionary 14 is changed, the command is inputted from the terminal equipment 16 and the dictionary editing part 15 is started, whereby the content of the editing part 15 is added and changed. Thus, the dictionary is securely and speedily corrected by the editing device itself.

Description

[Detailed Description of the Invention] [Summary] An editing terminal for editing a character or graphic pattern, which is permanently installed in a recognition device, or which is normally unconnected but connected during use, and the character or graphic pattern. It comprises a recognition dictionary used for pattern recognition and a dictionary editing section that edits the recognition dictionary, and by activating the dictionary editing section by inputting a command from the editing terminal or by an interrupt means,
The recognition device itself changes the contents of the recognition dictionary.

[Industrial application field]

The present invention relates to a recognition device, and particularly to a recognition device equipped with a mechanism for freely changing a recognition dictionary included in the recognition device.

With the recent spread of recognition devices and the diversification of recognition contents,
As each user has come to require a unique recognition dictionary, it is no longer possible to change the recognition dictionary offline using a general-purpose computer as in the past.
It has become necessary to be able to quickly change recognition dictionaries in response to user requests.

[Prior art and problems to be solved by the invention] FIG. 4 is a diagram illustrating a conventional recognition dictionary changing method.

Conventional recognition devices such as the character recognition device 9 and the drawing recognition device do not have a means for changing the recognition dictionary in the recognition device itself due to an economical orientation.

Therefore, when it becomes necessary to change the recognition dictionary in the recognition device l for reasons such as improving recognition performance or changing the shape of the recognition target, the contents of the recognition dictionary can be saved on a floppy disk. As shown in the figure, the recognition dictionary is re-created on the general-purpose computer 2 according to instructions from the editing terminal 21 of the external general-purpose computer 2.

In addition, the validity of the recognition dictionary created in this way was confirmed by simulation on the general-purpose computer 2.
When the method of ffl recognition or 8-simulation takes time, the recognition device 1 actually executes recognition processing to confirm the validity of the recognition dictionary.

For this reason, there is a problem in that when a large number of users make different change requests, it is not possible to respond quickly.

In view of the above-mentioned conventional drawbacks, the present invention provides a character recognition device.

It is an object of the present invention to provide a recognition device such as a drawing recognition device that can quickly respond to a user-specific change request for a recognition dictionary used for recognition.

[Means for solving problems]

Hereinafter, the configuration and editing operation of a recognition device equipped with a recognition dictionary editing mechanism of the present invention will be explained with reference to FIGS. 1 to 3.

First, an outline of the normal recognition operation in the recognition device of the present invention will be explained. When the recognition device is powered on, the contents of the recognition dictionary, system program, etc. are transmitted from the data input/output device 17 as shown in the figure. The recognition dictionary 14. The data is loaded into a storage device (not shown) in the control unit 11.

The control unit 11 executes the system program to control the observation unit (for example, a scanner).

tablet, etc.) 12, generates a video signal of a character or graphic pattern from the paper surface to be recognized and controls the control plate unit 1.
It will be sent to 1.

In the control unit 11, by sending the video signal to the recognition unit 13, the recognition unit 13 refers to the recognition dictionary 14, and
The video signal read by the observation section 12 is recognized, and the recognition result is sent back to the control section 11.

In the present invention, the recognition dictionary 14 necessary for the above recognition operation is
and a dictionary editing section 15 which is in charge of changing the contents of the dictionary.

An editing terminal 16 for performing dictionary editing operations on the recognition dictionary 14 is permanently installed or can be connected as needed.

Then, when you want to change the contents of the recognition dictionary 14,
The control unit 1 receives commands input from the editing terminal 16.
1 decrypts the information, or an interrupt means from the editing terminal 16 (specifically, by pressing a specific key on the keyboard 16a of the terminal A 16, the control unit 11 can be interrupted. ) etc., the control unit 11
The dictionary editing section 15 provided for carrying out the present invention is activated.

After the dictionary editing section 15 is activated, editing operations are performed using the editing terminal 16, for example, through interactive operations.
