Abstract

PURPOSE:To produce drawings with high efficiency by displaying the image of an inputted draft on a picture of CRT graphic display in the form of contour data. CONSTITUTION:The image of a draft inputted via an original image input means 1 is stored in an original image memory means 2. At the same time, the contour data on the draft image is stored in an original image contour memory means 4 via a contour tracing means 3. Furthermore, the line pattern data on the draft is stored in a line pattern memory means 6 via a line tracing means 5. These contour and line pattern data are put on each other and displayed on a CRT graphic display 7. Then a correcting instruction is given to a line pattern correcting means 9 from a line pattern correction instructing means 8. Thus the line pattern data is corrected.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drawing production device, and particularly to a drawing production device that handles drawings consisting of line figures based on draft manuscripts.

[Conventional technology]

A conventional drawing creation device is a so-called CAD system, and includes a line figure storage means for storing line figure data, a line figure display means for displaying the line figure data to an operator, and a line figure storage means for storing line figure data, and a line figure display means for displaying the line figure data to an operator. Line figure modification instructing means for accepting instructions for modifying figure data; and Line figure modifying means for updating the line figure data stored in the line figure storage means in accordance with the modification instructions given through the line figure modifying instructing means. It consists of:

FIG. 2 is a block diagram showing an example of a conventional drawing creation device.

The drawing producing apparatus shown in FIG. 2 includes a line figure storage means 6, a line figure display means 10, a line figure modification instruction means 8, and a line figure correction means 9.

Here, the line figure storage means 6 stores line figure data. The line figure display means 10 reads the line figure data C' from the line figure storage means 6 and displays it on a CRT graphic display or the like. The line figure correction instruction means 8 includes a CRT graphic display light pen, a tablet, a mouse,
It receives an operator's correction instruction for line figure data given by a trackball, key switch, keyboard, etc., and gives a correction instruction d to the line figure correction means 9.

The line figure modification means 9 reads the line figure data Co1d from the line figure storage means 6, updates it based on the modification instruction d, and writes it back as line figure data Cnew.

Generally, in the initial state, the contents of the line figure storage means 6 are empty, and the operator instructs corrections while comparing the line figure displayed on the line figure display means 10 based on the nine draft manuscripts kept at hand. The means 8 is operated to create a fair drawing in the line figure storage means 6.

[Problems to be Solved by the Invention] In the above-mentioned conventional drawing creation device, since nothing is displayed on the line figure display means IO in the initial state, it is difficult to layout the figures in one drawing. The operator must always compare the draft document in hand with the display on the line figure display means 10, which has drawbacks such as great fatigue on the part of the operator and difficulty in detecting input errors in figures.

[Means for solving problems]

The drawing creation device of the present invention includes an original image input means for inputting a draft document, an original image storage means for storing the original image data obtained by the original image input means, and an outline by tracing the original image data. contour tracing means for extracting data; original image contour storage means for storing the contour data; line tracing means for tracing the original image data to extract line figure data; and storing and displaying the line figure data. a contour/line figure display means for displaying line figure data; a line figure correction instruction means for receiving an operator's instruction to modify the line figure data; and a line figure storage according to the correction instruction given through the line figure correction instruction means.

and a line figure modification means for updating the line figure data stored in the means.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. The drawing creation device shown in FIG.
, contour/line figure display means 7 , and line figure correction instruction means 8
and a line figure correction means 9.

ζThe original image input means 1 inputs an image of a draft document using a facsimile machine, a scanner device, a TV right camera, etc., and stores it in the original image storage means 2 as original image data a. The contour tracing means 3 reads the original image data a' from the original image storage means 2, traces the boundary between the white area and the black area in the image of the draft document, and uses the tracing locus as outline data b to obtain the original image. It is stored in the contour storage means 4. The line tracing means 5 reads the original image data a' from the original image storage means 2, extracts line segments from the image of the draft document, and stores them as line figure data C in the line figure storage means 6. The contour/line figure display means 7 reads out the contour data b' from the original image contour storage means 4, and also reads out the line figure data C' from the line figure storage means 6, superimposes the two, and displays the CRT graphic data at the same time. Display on spray etc. The line figure modification instruction means 8 is a CRT graphic display light display.

Tablets, mice, trackballs, key switches,
It receives an operator's instruction to modify the line figure data given by a keyboard or the like, and gives a correction instruction d to the line figure modifying means 9. The line figure modification means 9 reads the line figure data from the line figure storage means 6 and writes it back as line figure data Cnew.

〔Effect of the invention〕

The drawing creation device of the present invention is capable of displaying an image of a draft manuscript in the form of contour data on the screen of a CRT graphic display, so that the operator can keep it at hand. There is no need to compare the draft document with the screen, and operator fatigue is reduced.Furthermore, the initial layout of the shapes on the screen is based on the outline data of the image of the draft document displayed on the screen. If you do it over and over again, it will become easier and more reliable. Furthermore, since it is possible to work while constantly comparing the image of the draft document and the line figure being created on the same screen, the drawing creation apparatus of the present invention reduces the number of mistakes. This has the advantage that drawing creation work can be done in a shorter time than with conventional equipment.
