Abstract

PURPOSE:To produce quickly an accurate overall drawing by inserting automatically a part of the overall drawing via an automatic correcting part for detailed drawing in case the drawing is read and the drawing data is produced. CONSTITUTION:The picture data binary coded by a drawing reading part 1 is supplied to an exterior line recognizing part 2. Then the form and the size of a pattern are extracted out of the drawing data and approximated by a straight line and a circular arc to be delivered to a recognition correcting part 3. The drawing data on the output of the part 3 is sent to an automatic correcting part 6 for detailed drawing if a detailed drawing B is partly included in an input drawing 11. The part 6 designates a specific position in an overall drawing A which is equivalent to the pattern of the drawing B. Then a part B1 which is replaced with the pattern of the drawing B is designated within the drawing A. Hereafter the data on the part B1 which is included in the data on the drawing A and designated for replacement is erased automatically together with addition of the data obtained when the pattern of the drawing B is moved to a designated position. Thus the drawing data on the drawing A is completed with correction performed by the drawing B.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drawing data creation method for reading drawings and creating graphic data.

[Conventional technology]

FIG. 3 is a drawing data creation circuit diagram for carrying out the conventional drawing data creation method. Reference numeral 3 denotes a recognition correction unit that recognizes and corrects the drawing, 4 a detailed diagram interaction correction unit, and 5 a drawing registration unit that registers the corrected drawing.

Next, the operation will be explained. The drawing is input to a drawing reading section 1 such as a 7-axis VH or an image scanner. The drawing data binarized by the drawing reading section 1 is input to the outline recognition section 2. The outline recognition unit 2 extracts data related to the shape and dimensions of the figure from the drawing data, approximates the figure with straight lines and circular arcs, and sends the approximation to the recognition correction unit 3.

In the recognition correction section 3, if there is an error in the shape or dimensions of the figure recognized up to the outline recognition section 2, it is corrected in an interactive manner. If the drawing data does not include a detailed drawing of a part of the overall drawing in addition to the overall drawing,
Thereafter, it is sent to the drawing registration unit 5 and registered as a drawing. Further, if a detailed drawing is included, the drawing data is sent to the detailed drawing interaction correction section 4. In the detailed drawing dialogue correction section 4, a person interactively corrects the portion Bl corresponding to the detailed drawing B in the overall drawing A one by one while looking at the drawing 11 shown in FIG. 4 so that it becomes equal to the detailed drawing B. . When the modification is completed, the drawing data is sent to the drawing registration section 5 and registered as a drawing.

[Problem that the invention seeks to solve]

Since the conventional drawing input method is configured as described above, if drawing 11 includes not only the general view A but also a detailed view B of a part of the general view A, the drawing in which a person has been recognized is The part Bl corresponding to the detailed drawing B of the overall drawing A in No. 11 must be corrected interactively while looking at the drawing so that it becomes equal to the detailed drawing B, which is time consuming and the operation is complicated. There was a problem.

This invention was made to solve the above-mentioned problems, and when drawing 11 includes a detailed view B of a part of the general view A, the drawing data for the general view A is
The purpose is to obtain a drawing data creation method that allows correction based on a detailed drawing B with simple operations and in a short time.

[Means for solving problems]

The drawing data creation method according to the present invention is such that, when a drawing includes an overall view and details of a part of the overall view, the above part is automatically corrected by the detailed drawing automatic correction means using the drawing data of the detailed drawing. This is what I did.

[For production]

The detailed view automatic correction unit in this invention interactively specifies the part corresponding to the detailed view in the drawing data for the overall view of the drawing. automatically replaces it with the drawing data.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, reference numeral 6 denotes a detailed view automatic correction section, which is used in place of the detailed view interaction correction section shown in FIG. Also, since the other configurations are the same as shown in Figure 3,
I will omit that duplicate explanation.

Next, the operation of this embodiment will be explained in detail with reference to FIG.

First, a drawing is input into a drawing reading section 1 such as a facsimile or an image scanner. The drawing data binarized by the drawing reading section 1 is input to the outline recognition section 2.

The outline recognition unit 2 extracts data related to the shape and dimensions of the figure from the drawing data, approximates the figure with straight lines and circular arcs, and sends the approximation to the recognition correction unit 3. Recognition correction part 3
Now, if there is an error in the shape or dimensions of the figure recognized up to the outline recognition section 2, it will be corrected interactively.0 And the drawing data output from the recognition correction section 3 will be partially added to the input drawing 11. If detailed drawing B of is not included,
It is sent to the drawing registration unit 5 and registered as a drawing. on the other hand,
If the detailed drawing B is included, the drawing data is sent to the detailed drawing automatic correction section 6. For example, if the input drawing 11 is as shown in FIG. 2, the detailed drawing automatic correction unit 6
First, a person interactively specifies the reference point P corresponding to each other for the general view A and detailed view B to specify the position of the figure in the detailed view B on the general view A,
Thereafter, a portion B1 in the overall view A to be replaced with the figure in the detailed view B is specified. Then, the next step is to automatically select the part B that is specified to be replaced in the drawing data of the overall drawing A.
1 data is deleted, and the data obtained when the figure of detailed drawing B is moved to the specified position is added to that mark. In this way, the drawing data of the general view A corrected by the detailed view B is completed. Then, this drawing data is registered as a drawing in the drawing registration section 5.

In this way, the operator can move the detailed drawing to a predetermined part of the overall drawing using the automatic detail drawing 5 main section 6, for example, with just one key operation, without having to interact with the operator to modify the figure while looking at each drawing. This can be automatically replaced, and as a result, the overall view and the details of each part of the overall view can be accurately represented on the drawing.

〔Effect of the invention〕

As described above, according to the present invention, when reading a drawing and creating drawing data, the detailed drawing automatic correction unit automatically changes a detailed drawing showing a part of the overall drawing in detail to that part. This has the effect of making it possible to quickly create an accurate overall diagram with simple operations.

Claims (1)

[Claims] In a drawing data creation method that reads a drawing and creates drawing data, if the drawing includes an overall drawing and a detailed drawing of a part of the overall drawing, the detailed drawing automatic correction means automatically corrects the details of the overall drawing.
