Abstract

PURPOSE:To permit efficient management of a figure recognition system by using a picture image memory belonging to the side of the main recognition processing device as memory map and outputting its contents as dot image on the screen. CONSTITUTION:The image surface input 1a by an image scanner 1 is sequentially supplied to a recognition processing device 2. The initial input image 4a belonging to the bit map 4 holds the scanner input level image input. The class is resolved in accordance with data attributes included in the image 4a and registered in separate dot map class as recognition result patterns 4b-4e. The monitor display 3 has a screen buffer 12 corresponding to the image 4a and patterns 4b-4e. With this constitution, partial images extracted by sequential incision 5 of the recognition portion are canceled from the bit map class of the image 4a with the timing the recognition results are registered on the map 4.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a display method for an automatic drawing reading device.

[Conventional technology]

In general, an automatic drawing reading device does not attach any meaning to the drawing at the input stage, and treats the drawing as a dot image that is quickly developed by a scanner. Furthermore, after the recognition processing necessary for automatic reading is performed and the content is made meaningful, all written content on the drawing is coded and treated as an accumulation of vectors, symbols, characters, etc.

Therefore, if you want to monitor the process in which the graphic image input to the recognition processing device is correctly converted into meaning, the monitor display function must have an image display function and a graphic display function. Various methods have been devised. In order to display an input image on a monitor, a method is generally used in which all line segments (including strokes of characters) included in a graphic image are vectorized and displayed graphically.

[Problems to be solved]

However, in addition to the original recognition processing, processing to generate a large amount of vector data is required, which poses a problem in that it creates a large burden on system operation.

[Means for solving problems]

The present invention solves the above-mentioned problems, and is mainly applicable to monitor display systems for devices that automatically read drawings containing line segments, symbols, characters, etc. ! The image memory belonging to the recognition processing device is used as a bitmap, and its contents are output as dot images on the screen of the monitor display function.

〔Example〕

Next, the embodiment will be described with reference to FIGS. 1 to 3.

Fig. 1 is a diagram showing a schematic configuration of an automatic reading device to which an embodiment of the display method according to the present invention is applied, Fig. 2 is a block diagram showing the functions of the above device, and Figs. It is a figure which shows each signal waveform of the said function.

In the figure, the data flow is as follows: The image screen 1a from the image scanner 1 is sequentially processed by the recognition processing device 1#2 and the string I-display 3. This is essential for system configuration including recognition. In addition to bitmap 4, etc., the recognition processing unit f12
Main storage device 9, recognition processing addition unit 10. Bitmarks 1
- has a copy of 11.

The monitor display 3 displays the bitmap 40 dot array belonging to the recognition processing device 2 on the image display 15 without processing it.

That is, the screen buffer 12 of the monitor display 3 always holds the same contents as the bitmap 4 of the recognition processing device 2.

Next, its functions will be explained. bit map
The initial input image 4a belonging to No. 4 retains image input at the scanner human level before being made significant by recognition processing.

Next, target recognition unit images are sequentially extracted one by one by the cutout function 5 from the initial χ image, as shown in Figure 3, and then recognized by the recognition processing function 6 as shown in Figure 3.
is input and made significant.

The sequential extraction function 5 and the recognition processing function 6 are not particularly described because they do not fall within the scope of the present invention.

Here, the image file 7 is a food pace drawing file that is reconstructed as shown in FIG. 30 using the results made significant above. In this example, the key for reconstruction is initial image 4a.
It uses a vector value that indicates the cutting position from. l
i! ! The identification result patterns 4b to 4e are patterns obtained by patterning the contents of the image file 7 by the patterning function 8 as shown in FIG. [F]
The recognition result patterns 4b to 4e are registered in different dot map classes as shown in FIG.

The monitor display 3 has a screen buffer 12 corresponding to the bitmap class (initial input image 4a, gm result patterns 4b to 4e) K of the bitmap 4 belonging to the recognition processing device 2. ! 8! A channel connection is made between the identification processing device 2 and the monitor display 3 using a communication interface or a peripheral device connection method, but in this embodiment, since interactive operation between both devices 2 and 3 is assumed, the speed is sufficiently high. It must be possible to perform image transfer (see Figure 3, 0).

The intended effect of this embodiment is to observe the process in which the initial input image 4a is successively correctly recognized on the monitor display 3 as shown in FIGS. 3(I) and 3(J), and the screen is replaced with the results. It is something to do. Therefore, for the partial images extracted from the initial human image 4a by the sequential extraction 5 for 111W, the MR results are shown in the bitmap 4.
It is deleted from the bitmap class of the initial human-powered image 4a at the same time that it is registered above. Transfer of the image pattern on the bitmap 4 (see FIG. 3) is carried out only when the changed class is busy every time the content of the bitmap 4 is changed.

〔Effect of the invention〕

As explained above, the present invention allows the recognition processing function to monitor the automatic reading status of drawings, which changes from the image level to the graphic level, on a single image display. Ii! ! knowledge system system configuration,
