Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a drawing creation device that creates a single sheet of figures superimposed from a plurality of drawings of different scales with all the scales matched.

[Conventional technology]

FIG. 3 is a block connection diagram showing a conventional drawing creation device. In the figure, 1 is a digitizer as a drawing input device, 2 is a computer, and the graphic data converted into digital signals is used as position information given. Arithmetic processing is performed, and the results are displayed on a display device such as a 5CRT display. Numeral 4 is a topographical map, for example, representing topography dat, which is superimposed to obtain a superimposed drawing, and numeral 5 is a pipe network map drawn on the sewer pipe network 5b' in topography 5a of a scale different from this topographical map. Note that 6 is a pipe network management map displayed on the display device 6 by superimposing the topographic map 4 and the pipe network map 5.

Next, the operation will be explained.

First, the above-mentioned topographic map 4 and pipe network map 5 are placed one after another on the coordinate board, and the lines on each map are traced with a cursor. As a result, each position data on the line is read into the computer as a digital signal, temporarily stored in memory, and then each same sound overlap 3 instructions? The computer 2 generates all the processing for the pipe network management diagrams 6 for both figures, and displays or outputs them on a display device or other output device.

[Problem that the invention seeks to solve]

Conventional drawing creation devices are configured as described above, so it is necessary to trace the input figures manually, which is very time consuming, and the input data is easily leaked. In addition, when there is a newly constructed or modified pipe network, it is necessary to trace the existing pipe network control map or topographic map with high precision using a digitizer, which makes this work difficult. There were problems such as it being extremely difficult and requiring a lot of effort and perseverance. In addition, each of Figures 4 and 5 differs in terms of scale, author, date of creation, etc., and simply superimposing the two Figures 4 and 5 will not result in a complete match; it is necessary to measure all dimensions. What, each figure? There was also the problem that each part needed to be corrected, resulting in a huge loss of work.

This invention was made in order to solve all of the above-mentioned problems, and it makes it easy to input drawing data and prevents input omissions, and also makes it possible to easily input drawing data without overlapping the same scale.
The aim is to get all the money you need with a drawing making device that can be quickly and accurately obtained.

Means for Solving All Problems C] Does the drawing creation device according to the present invention produce multiple drawings with different scales? It is automatically read by Mage input device and each figure read is fully enlarged.

A computer performs 7 overlapping figure processing operations by rotating or moving the figure 9 times, displays the figure processing status on all display devices, and is configured to allow alignment of drawings of different scales to be performed while fully monitoring. It is.

[Effect]

The image input device according to the present invention automatically reads the contents of each drawing as dot data while scanning it, and based on this dot data, the computer performs all overlapping of the image data, and then converts each of the overlaid data into an image pattern again. In addition to displaying the image on the display device, the computer's functions such as enlarging, reducing, rotating twice, and moving act to enable the scale of each figure to be adjusted.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained below.

In Figure 1, 50 is a pipe network diagram as an equipment drawing, 70
51 is a topographic map with roads etc. drawn on it, 51 is a pipe network map 50 is a facsimile-type image input device for fully automatic weaving,
Reference numeral 71 denotes an image input device that automatically reads the topographical map 70, and a vector input device sound can be used if necessary. 8o is a calculator, each image input device 51.71
The input image data is processed as fully binarized image data, pre-processed such as noise removal, and line recognition.

Shape analysis and identification judgment such as symbol recognition and 2-character recognition are performed, and these are stored in memory as 'ftz value image data, and the scales of the topographical map 7o and the pipe network map 50 are associated. It has the function of enlarging, reducing, moving, or rotating image data in order to do so. Reference numeral 90 denotes a display device for interactive processing, such as a graphic display, which can monitor the input image, the two superimposed images, and the above-mentioned alignment status, as well as monitor the final drawing.

Next, the operation will be explained.

First, the topographic base, which is the background of the pipe network map 50, is automatically read by the image input device 51, and based on this, the computer 80 converts the topographic map into run-length vectors, automatically recognizes the drawing frame, and corrects the size. Create all high-precision topographic maps. It also determines roads through line vectorization (line recognition) and shape analysis, recognizes and extracts characters and symbols, registers the topographic map in a hierarchical manner, and temporarily stores these in memory.

Next, the pipe network homophone image input device 71 as an equipment drawing
The computer automatically recognizes the pipe network and creates a pipe network diagram by correlating it with the existing equipment data, which is then temporarily stored in all memory.

Next, such topographic map data and pipe network map data, total
1 JIPa calls from each memory, synthesizes and edits it, and displays it on the display device 90 as a superimposed diagram as shown in FIG. Roads drawn on topographical map 70, 32.
33 is the road and pipe network drawn in the pipe network diagram 50.

The superimposed diagram displayed in this way is shown in Figure 2 ia
As shown in l, roads 31 and 32 are significantly shifted,
In accordance with all external commands, the computer 80 aligns the 62 maps with the map 61 by moving them as shown in FIG. In some cases, editing of alignment may be performed.The overlaid drawings created in this way are
Furthermore, you can make all necessary dialogue corrections and output them as final drawings.

In this way, by inputting images of drawings, overlapping drawings can be created accurately and quickly. Also.

By displaying the pipe network map and the topographic map in different colors on the display device, it is possible to completely prevent omissions in the drawings.

In the above description, a case has been described in which one image human-powered device is used for coloring the topographic map (d) and for reading the pipe network map, but it is also possible to use both of these devices together.

In addition, in the above embodiment, a diagram of the equipment was explained as a facility diagram, but it may also be a civil engineering/architectural diagram of a plant, a layout/mechanism diagram of power generation/transformation equipment, an 'electrical sequence diagram, etc. Similar effect: golden smell.

〔Effect of the invention〕

As described above, according to the present invention, a plurality of drawings with different scales are automatically read by the image input device 1ffii/ic, and the captured image is fully enlarged, reduced nine times, or moved to the display device. The structure is configured to perform superimposition processing on the top of the screen, thereby aligning the plurality of drawings (-), which eliminates manual work such as image input using a conventional digitizer.

This has the effect of not only being able to omit operations, but also speeding up image input processing and completely preventing input omissions.
