Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a computer aided design (Computer Aided).
The present invention relates to an electronic file device to which a Design (CAD) device is connected, and more particularly, to a method of registering image data capable of automatically extracting a search keyword when converting an image generated by the CAD device into an electronic file. .

[0002]

2. Description of the Related Art In recent years, the fourth OA (office) has been developed in which electronic file devices follow word processors, personal computers and facsimile machines.
(Automation) equipment, and it has become possible to store a large amount of documents and drawings on an optical disk as image information. That is, the electronic filing device inputs an original drawing from a scanner and stores a large amount of digitized image data on an optical disk one by one. Also, if necessary,
The image data is taken out from the optical disk and displayed and printed.

On the other hand, a simple method for retrieving image data is to display and confirm the image data from the first page of the optical disc. However, this method has a fatal defect that the search efficiency is significantly deteriorated because it is unknown when the image data is displayed as desired. Therefore, in order to realize an effective search, a keyword indicating the content of the image data is added when registering the image data.

[0004] In searching, a method of searching for desired image data using a keyword is widely used. As a method of attaching the keyword, in an image including a document or the like, a method of assigning an important word or phrase from the document is usually used. Further, in a drawing or the like, words such as a drawing name expressing the contents of the drawing are assigned. Here, the above keyword is defined as a character keyword to distinguish it from the concept described below.

[0005] However, it is difficult to say that the above-mentioned character keywords sufficiently express graphic features such as outlines of the drawings. For this reason, another method has been devised to make it easier to search for a drawing by considering a keyword that represents the characteristic of a figure in a form.

The method invented for the above purpose is disclosed in
This is a conventional technique described in JP-A-83179.

That is, an original figure to be registered is read by an input device, and the read data is displayed by a display device. The user manually traces the outline of the image using a pointing device (mouse, tablet, etc.). Then, the figure formed by tracing is reduced, and is used as a keyword. Since only the characteristic portion of the image is extracted from the reduced figure created in this way, a desired image and another image can be easily identified. Also, by shrinking,
Many created keywords can be displayed collectively on the keyword display screen of the display device. Finally, if the displayed reduced figure is specified using a pointing device, etc.,
Desired image data is read from an optical disk.

As described above, in the above-described conventional technology, a graphic itself can be defined as a keyword. Therefore, an external pattern that matches the intuition of the operator can be used as a keyword, and a target image can be easily searched from a large-capacity optical disk. Other related conventional examples are disclosed in, for example, Japanese Patent Application Laid-Open No. 62-720.
67, 62-93757.

[0009]

In the prior art described above, the search efficiency has been greatly improved, but there still remains a problem in the keyword registration operation in both the outer shape and the character.

[0010] In other words, the creation of the outline keywords described above requires the operator to use the pointing device to trace the outline of each input image using a pointing device. Therefore, since the image data is registered one by one, the above-described operation occurs, and there is a disadvantage that the registration operation requires a long time.

[0011] Further, in creating a character keyword,
It is necessary to manually derive and input the correct words and phrases from the images to be registered. In addition, a single keyword is difficult to understand because it is difficult to understand. In many cases, a plurality of keywords are required.

An object of the present invention is to provide a method of registering image data which can automatically create a character and an outline keyword in an electronic file device connected to a CAD device for generating vector data and automate the registration of image data. Is to do.

[0013]

In order to achieve the above object, according to the present invention, when a vector data file is input and converted into raster (image) data, the contents of the file satisfying a preset attribute condition are used. Is used as a keyword, raster data is registered, and a search is performed using this keyword.

According to the present invention, a vector-raster (image) converter is provided in an electronic file device to which a CAD device for generating vector data of a drawing is connected. The keyword is automatically extracted from the generated vector data. The extracting means uses the fact that vector data is composed of attributes such as line types and coordinate values, and sets in advance attribute conditions that well represent the characteristics of the generated drawing, and sets the attribute conditions as the attribute conditions. It has a function of extracting vector data having a matching attribute, and (1) includes not only those that are raster-converted by registration but also those that are not converted.

According to the configuration of the present invention described above, the vector-raster converter placed inside the electronic file device to which the CAD device is connected, between the two devices, or inside the CAD device, The data is converted into raster data of an electronic file device. In the conversion process, the above-described means is realized by using the code information of the vector data.

First, as a means for cutting out a file name to be registered by the first means, a registration file name sent from the vector device to the electronic file device when registering an image is used as a keyword.

Means for cutting out a title field based on the second format information extracts character attribute data of the code information of the vector data, extracts a character code of the code information within a predetermined coordinate value range, and outputs a keyword. And

The means for extracting the longest size code of the figure in the third drawing extracts the numerical attribute of the code information, compares it in the vertical and horizontal directions, and extracts the maximum size. Let the extracted code be a keyword.

Means for extracting the primitives and topology constituting the fourth graphic, extracting the line type attribute of the code information of the fifth vector data, and extracting the icon code having similarity from the reduced graphic The receiving unit receives the vector data sorted by the coordinate position from the CAD device, and extracts all the line type attributes of the code information of the vector data. Then, the extracted vector data is classified into graphic units. An outer shape can be obtained by extracting the largest figure from the classified figures. Regarding the fourth means,
The main primitives can be extracted by obtaining the outline.
Further, as described above, since the code information is sorted by the coordinate position, the order of the primitives sequentially taken out is determined by their positional relationship, so that the topology can be extracted. Then, fifthly, the above-mentioned topology is used to determine whether there is an icon code having a similarity of the extracted figure. This is because the topology of the icon code is stored in the accessory information of the icon code. If there is an icon code with a matching topology, the similarity is close, so the icon code is used as a keyword. If not, the taken figure is reduced to a predetermined size and newly registered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a block diagram for realizing the present invention, and FIG. 4 is an operation flowchart of the present invention.

FIG. 1 shows a CAD system (hereinafter referred to as CAD) 11 of a vector device, a vector-raster converter (hereinafter referred to as a data converter) 12 for extracting keywords of the present invention, and image registration management. An electronic file device (hereinafter, referred to as an electronic file) 13 to be executed is connected.
The data converter 12 includes a vector interface 21 that receives data sent from the CAD 11, a data conversion RAM that converts the vector data received by the vector interface 21 into raster data and stores the raster data.
(Hereinafter referred to as DR) 22, a raster interface 23 for sending image data and keywords to the electronic file 13 after data conversion, and a keyword R for storing extracted keywords.
It comprises an AM (hereinafter referred to as KR) 24 and a control unit 25 which controls the data converter 12 and converts vector data into raster data.

FIG. 2 shows a drawing created by CAD 11, and FIG. 3 shows a data structure managed by CAD 11 in FIG. FIG. 3 shows data to be processed by the CAD 11 and the vector interface 21. The data in FIG. 3 is sorted in the CAD 11 in ascending order according to the item of coordinate 1 in FIG. It is sorted by y of one coordinate item after sorting on x of one coordinate item in FIG.

Next, FIG. 4 will be described in detail.

The process 401 is a process for extracting a file name and using it as a keyword. The drawing of FIG. 2 created in the electronic file 13 from the CAD 11 is registered. The command for registration requires a source file name and a destination file name as in file transfer. The transfer source file name is a file name managed by the CAD 11, and the transfer destination file name is a keyword required for the electronic file 13. Therefore, the transfer destination file name is the data that is received first by the vector interface 21 at the time of registration, and the processing unit 25 converts the transfer destination file name into KR2
4 can be used as a keyword.

In the process 402, the vector interface 21 receives the data shown in FIG.

Step 403 determines whether the transfer data has been completed. If not, the process proceeds to step 404;

Processing 404, processing 405, and processing 406
Determine the attributes of the data. The attribute of the data to be determined is the item of the attribute in FIG.
If the attribute is a numerical attribute, the process proceeds to step 409; if the attribute is a solid line, the process proceeds to step 411. Otherwise, the process proceeds to step 412.

In steps 407 and 408, keywords are extracted based on the format information. The format information is positional information of characters written in the frame 31 of FIG. 2, and the words to be keywords are the character strings 32 to 36 of FIG.
Character. Then, in the range determination in the process 407, since the frame 31 in FIG. 2 is at the lower right of the drawing, it is determined whether the coordinates of the character attribute primitive are within the range. If it is determined that the coordinates are within the range, the character string of the value item of the data shown in FIG. 3 is extracted in step 408 and stored in KR24. If it is out of the range, the process proceeds to processing 412. Also, after the process 408 is completed, the process proceeds to the process 412.

In processing 409 and processing 410, the maximum size of the graphic 37 in FIG. 2 is found in the x direction and the y direction, and is used as a keyword. In processing 409, it is determined whether the value item in FIG. 3 is the maximum value. For the maximum value, a work area is set in the KR 24, the initial value is set to 0, and the value is compared with the value of the value item of the numerical attribute data. If the value of the data is larger than the value of the work area of the KR24, the process 410 swaps the value of the work area of the KR24 with the value of the data. The processing is
This is also performed in the x and y directions. Therefore, when the data is completed, the value indicated in the work area of KR24 is the maximum value, which is the keyword. Therefore, if the maximum value is not the maximum value in the process 409 and if the process 410 is completed, the process proceeds to the process 412.

The process 411 converts the data of the solid line attribute into KR2
4 are stored in the order in which they are found. Thereafter, the process proceeds to the process 412. The method for extracting the remaining two keywords will be described from the process 440 in FIG.

The process 412 converts the sent vector data of FIG. 3 into raster data. Since the DR 22 is a bitmap memory, the vector data is stored in the processing unit 25.
Analyze and write to DR22. Processing 4 after writing
Return to 02.

When the input data ends in process 403, D
All the registered data has been converted from vector data to raster data and written in R22, and the process proceeds to step 420.

The process 420 is a process for extracting the outline keyword from the data of the solid line attribute described above.
Go to 0.

The process 440 classifies the vector data of the solid line attribute stored in the KR 24 into graphic units. As a method of classification, since the data stored in the KR 24 is stored in the order found in the process 411, it is checked whether the first data and the next data have a contact point. Then, all the vector data of the solid line attribute stored in the KR 24 are checked and classified.

In the process 441, as a result of checking the contact points in the process 440, since the vector data is classified in units of several figures, the area of each figure is calculated from the classification to find the largest figure. . Then, since FIG. 2 is a single figure, in the process 441, the figure 37 in FIG. 2 is searched.

Then, in step 442, primitives constituting the figure and the topology between the primitives are extracted. From the vector data constituting the graphic 37 of FIG. 2 found in the processing 441, the graphic attribute of the vector data is processed 411.
By taking out in the order found in, the primitives that make up the figure can be extracted immediately. In the topology, a relation code of position information is added to the extracted primitive. Therefore, in the graphic 37 of FIG. 2, primitives can be extracted in the order of a circle, a rectangle, and a circle. The extracted keyword is stored in KR24. Then, the process proceeds to step 443 to extract the last keyword.

In the process 443, the electronic file 13 is sent to the KR 24 via the raster interface 23 as shown in FIG.
Is read. The read data of FIG. 6A has the data structure of the icon code of the electronic file 13. FIG. 6B shows an icon code corresponding to FIG. 6A.

In the process 444, the topology information read in the process 443 and the topology detected in the process 442 are compared with each other. Process 44
Proceed to 6.

In the process 445, the electronic file 13 in which the topology of the icon code information read in the process 443 matches the image is stored at any address, a code for adding the address is added, and the image is stored in the temporary KR24.

In step 446, a magnification for reducing the figure to a certain size is obtained in order to create a new icon code. At the determined magnification, the vector data of the solid line attribute stored in the KR 24 is converted into raster data and stored in the KR 24. Then, the information of the icon code is added. Then, when the processes 445 and 446 are completed, the process returns to the process 421.

With the above processing, five types of keywords are stored in the KR 24.

In the process 421, the converted raster data is sent from the DR 22 to the electronic file 13 via the raster interface 23. Then, when the transfer is completed, the process 44
Proceed to 2.

In the process 422, the keyword stored in the KR 24 is sent to the electronic file 13 via the raster interface 23. Therefore, in order to make it possible to select the type of keyword in the process 422, a keyword selection code is added to a command for registering an image from the CAD 11 to the electronic file 13. Therefore, the registration command is a transfer source file name, a transfer destination file name, and a keyword selection code. Then, the process 422 analyzes the keyword selection code, selects a keyword and sends it to the electronic file 13.

In the embodiment described above, five types of keywords are generated by one process, but the present invention is not limited to the generation of five types of keywords. If necessary, one type or two or more types of plural types of keywords can be generated for one drawing. Needless to say, this control can be appropriately selected by the control program of the control unit 22.

An embodiment of the retrieval according to the present invention will be described with reference to FIG.

Next, the operator inputs a keyword from the input device 53, sends the keyword to the search device 54, and sends the search information obtained by the search device 54 to the control unit 55. The control unit 55 sends the search information to the storage device 51 and causes the output device 52 to send raster data corresponding to the search information. Through the above processing, an image corresponding to the keyword input by the operator can be displayed on the output device 52.

A description will now be given of a process in which the operator inputs a keyword by not displaying the registered keyword but displaying the stored keyword and selecting the displayed keyword.

At the time of retrieval, a keyword group of the storage device 51 is sent to the output device 52 and the retrieval device 54 by a signal from the input device 53 to the control unit 55. The output device 52 displays the received keyword group and notifies the operator of the keyword. On the other hand, the operator selects a keyword, inputs the selected content from the input device 53, and sends it to the search device 54. The search device 54 creates search information from the received keyword group and the selected content, and sends the created search information to the control unit 55. Control unit 55
