[0007]

In the conventional drawing management system, there is no system that controls functions necessary for managing facilities.

[0008] For example, there is a system for inputting, storing and retrieving drawings.
It was a simple system to store it and simply retrieve the stored image. There is also a system called CAD, which has a drawing function. This is a system for creating and editing drawings, and consideration is given to using the drawn drawings for further data processing. There was a problem.

[0009] An image vector conversion system for converting data fetched as an image into a vector already exists. It is used in a recognition system that recognizes data by converting an image into a vector. However, as a result of recognition, the ID is simply added, and individual attributes are added to the recognized data. There was no system that could be used for processing.

[0010] In addition, a search system that uses data associated with equipment on the drawing (ie, attribute data) in association with the equipment on the drawing has already existed. It was not a system in which the attribute was added to the result and used for search processing.

The above-mentioned prior arts 1, 2, and 3 are examples of systems that attempt to integrate some functions among the already existing systems as described above. The problems described in 2 and 3 also have the following problems.

Since the graphic recognition system of the prior art 1 is constructed as described above, the operator must directly input all hundreds of thousands of existing drawings in accordance with the direct tracing method. It is necessary to register and check the coordinates of such vectors and symbols and the character codes, one by one, for each graphic unit, and there is a problem that the drawing information cannot be registered unless a huge input man-hour is processed. In addition, there is a problem that the operator needs to intervene because the combination of the drawing information and the attribute information is performed while checking with the graphic association device.

Further, the automatic drawing management apparatus of the prior art 2 has another problem that drawing information cannot be registered unless drawing and editing processing is performed using the input means.

The drawing registration system of the third conventional example inputs drawing information in the form of an image and automatically recognizes the drawing information. However, there is a problem that the automatically recognized figure is not processed by attribute information or tallying processing. There was a point.

Then, the recognizing unit 35 outputs the image drawing 4
For 3a, for example, a recognition process is performed to determine whether there is a telephone pole, a manhole, or a building. In this example, since the telephone pole is represented by a circle, the recognition unit determines whether or not the circle is present in the image drawing 43a, and recognizes the poles P1 to P4. Similarly, manholes are represented by crosses,
The recognizing unit 35 determines whether there is a cross in the image drawing, and recognizes manholes W1 to W3. In this image drawing, a straight closed loop indicates a building, and the recognition unit 35 recognizes a closed loop area surrounded by a straight line from the image drawing 43a as a building. In that case, recognition is performed by performing vector conversion for converting raster data into a vector. In this case, the buildings B1 to B3 are recognized.

Next, the operation of the attribute assigning unit 36 will be described. FIG. 3 is a diagram illustrating an attribute format prepared in advance by the attribute assigning unit 36.

As shown in FIG. 6B, the power outlets on each floor of the building B1 are supplied with power from a power pole P1. Therefore, by following these relationships, the attribute search unit 37 can search which power pole the power outlet receives power from.

Embodiment 2 FIG. In the first embodiment, the case where a conventional batch-type recognition method is used for the recognition unit 35 has been described. Here, the case where an interactive recognition method is used will be described.

The equipment management department already stores a large amount of drawings.
It is necessary to input information required for equipment management from existing drawings into a computer. However, in a drawing, there are many contacts and overlaps between entry elements, or elements are blurred or interrupted due to repetition of copying or the like, so that a conventional automatic input system cannot be applied. However, it takes enormous effort and time to manually input all the existing drawings by the CAD system.

In order to solve such a problem, an "interactive drawing recognition system" employing a "dynamic matching method" described below is used. This system inputs complex existing drawings as images from an image scanner, and does not indicate all the equipment objects in the drawing, but simply specifies the approximate type and position. The shape is automatically recognized.

In order to automatically input drawing information into a computer, it is necessary to recognize the position, shape, and type of symbols and lines drawn in the drawing. Since the recognition method based on the "tracking method" of recognizing the object was used, the drawing elements were drawn overlapping, or in the case of an existing drawing with breaks, the wrong line was tracked and a recognition error occurred There is a problem.

On the other hand, the “dynamic matching method”
From the approximate position of the target equipment specified by the operator, a model of the figure to be recognized is generated, the model is dynamically deformed, and the target is recognized by flexibly matching with the image data of the target. For this reason, even if the object and the background are drawn overlapping or the line is interrupted, the object can be recognized.

The objects to be recognized are dozens of simple symbols of a fixed size in the drawing, and symbols and lines of an indeterminate size (solid line,
(Broken line). Symbols can be expanded by registering. In addition to symbols and lines (solid lines and dashed lines), the object to be recognized can be a figure in which a symbol and a line are combined, and a line figure with a variable length drawn between the symbols. These figures analyze the structure of the image data based on the designated approximate position, and separate and recognize the object from its features. In addition, based on the approximate position specified by the operator, the system directly extracts, processes, and recognizes an image of a small area in the specified nearby area. It does not require hardware such as a computer, and can be processed independently by an engineering workstation or the like. Also,
This system can recognize only the objects to be managed as equipment and store them in a computer. Other parts can be saved as images as backgrounds. Also,
Recognized target image data can be automatically erased only necessary parts without erasing surrounding image data, even if drawing density is high, managing both image and vector data Can be.

FIG. 7 is a diagram showing the processing of this interactive drawing recognition system, and recognizes the equipment element in the drawing by the following processing procedures (a) to (e). (A) An existing drawing is input from an image scanner, and image data is displayed on a display. (B) Specify the general type and general position of the equipment to be recognized. x: Approximate position specified by operator (c) The system detects the target equipment and automatically recognizes the type and accurate position. (D) Only the image data of the recognized target equipment is deleted from the drawing. (E) Register the recognized equipment in the database.

As described above, according to the "dynamic matching method", "interactive drawing recognition" has a high recognition rate even when entry elements such as symbols, lines, and characters are overlapped in drawing recognition, or even when there is fading or interruption. The "interactive drawing recognition system" makes it possible to recognize complicated existing drawings with a high probability, which was impossible in the past. Since the user inputs the information of the drawing while interacting with the computer, the recognition result can be easily confirmed and corrected. This system, like the traditional system,
It does not require hardware such as a dedicated image processor or minicomputer, and can be processed by the engineering workstation alone.

Embodiment 3 FIG. In the above-described first embodiment, the case in which the equipment to be installed is a utility pole, a manhole, and a building has been described.
It may be a water pipe, a gas pipe, a fire hydrant, a park, a school, etc., and other elements to be installed. The equipment is not limited to the equipment shown in the above embodiment, but may be any equipment having attribute data.

Embodiment 4 FIG. In the first embodiment, the example of the road drawing is described. However, the present invention is not limited to the road drawing, and may be a railway drawing, a drawing of a building, or another drawing.

[0053]

As described above, according to the present invention, a specific drawing component is recognized from drawing information, attribute data is added to the recognized drawing component, and this can be used. Therefore, equipment management becomes efficient and flexible, and a better equipment management system can be provided.
