[Detailed Description of the Invention] [Purpose of the Invention (Industrial Field of Application) The present invention is based on the drawings in which the positions of a large number of holes are drawn.
The present invention relates to a position recognition device that can extract dimension and position data quickly and accurately.

(Prior art) Conventionally, when creating NC tape for drilling holes in a board using an NC tape making device, a worker reads a drawing of a hole with a figure drawn on it, and the operator reads the drawing. The data for making the NC tape for board holes is from the drawing.
A CAD system is used to input data into an NC tape production device. However, with this method, the holes are drawn because the workers are reading the drawings.

Not only does it take a lot of time to create NC tape,
Since the data is entered manually, there is a problem in that input errors occur and the NC tape cannot be created accurately.

Furthermore, isolated holes in a predetermined small area at an arbitrary position of the image data are extracted by adding size and position information to the figure. The hole holes extracted by adding size and position information by the extraction processing means are only those that are two circular shapes and smaller than a certain size among the figures, and the hole holes are the dimensions and the hole holes have the position.The final hole hole is A feature of the present invention is that the perforation that is recognized and output as a figure is configured to include a position detection processing means.

(Function) In the above-mentioned position recognition vR system, the image of the figure is inputted as binarized image data by the image data input processing means, and this input-processed image data is The figure 01 extraction processing means determines that a predetermined hole is a figure by comparing it with a dictionary that stores image patterns in advance, and furthermore, an isolated hole in a predetermined small area at an arbitrary position of the image data is determined to be a figure. The holes are extracted by adding size and position information to the holes, and the hole holes are extracted by the position detection processing means.Of the shapes, only those that are two circular shapes and are smaller than a certain size are determined by the hole size and the hole hole size. The final hole with position will be recognized as a figure and output.

(Example) The present invention will be described below with reference to an example shown in the drawings.

FIG. 1 shows an example of the main hardware configuration of a position recognition device according to the present invention. In Figure 1,

In FIG. 2, Akira indicates a position recognition device, an image data input processing means 8 that inputs and processes an image of a figure as image data converted into 21 scale, and an image input processed by this image data input processing means 8. Image data storage means for storing data and the image data inputted by the image data input processing means 8 are compared with a dictionary storing image patterns in advance to determine whether a predetermined hole is a figure, and furthermore, the above-mentioned side (small region connected image data extraction processing means 10 for extracting isolated holes in a predetermined small region at an arbitrary position of the elephant data by adding size and position information to the shape, and figure recognition processing means 11 for hole holes) The holes are extracted by adding size and position information by the figure recognition/extraction processing means. The hole size and hole size are recognized as figures, and the hole size and hole size are recognized as position detection processing means 12. 1
2, the recognition result output processing means 13 outputs the dimensions and the position data of the holes recognized by the above-mentioned NC tape producing device 7.

Next, the operation of the position recognition device constructed as described above will be described in detail.

The image data input processing means 8 converts an input image of a figure into binary image data using the drawing input section 1 and the address control hardware 4. for example,
An A3 size hole can store approximately 800 input image data for drawings.
It is converted into binary image data of 10,000 (2000x4000) pixels. Then, these image data are stored in the image data storage means 9 such as the image memory 2. In this case, the input image is not limited to figures, but also includes characters, general figures, line segments, and other elements, and from among these, Anaki selects image data of isolated figures that are candidate figures. , small area connected image data extraction processing means 10 by image processing processor 3 and address control hardware 4
Extract by.

That is, for example, in the case of an input image as shown in FIG. 3, the image data of small-scale isolated figures shown in ■ to ■ are extracted as elements, and the image data shown in ■ to ■ are not extracted. In addition, during this extraction, as shown in Table 1, the operator adds the coordinates of the intersection of the quadrangle circumscribing the figure and its diagonal. The extracted elements are recognized by the figure recognition processing means 11 as only those whose figures are circular and smaller than a certain size, and which are recognized as figures by the figure recognition processing means 11 (■ to ■).

Anaki passes (x, y) as a position to the recognition result output processing means 13. Then, in the recognition result output processing means 13, this 1. Based on P(x, y), Anaki outputs the NC tape creation data to the NC tape creation device 7 as the final result as shown in Table 2.

Table 2 As mentioned above, in the position recognition device for the hole markings of this embodiment, for the hole markings in which a large number of hole drawings are drawn, only the drawing is created, and the hole markings can be drawn at any position in the drawing. It is possible to automatically recognize the position and size of holes in figures and output them. Therefore, when creating NC tape for board drilling, the holes drawn on the drawing can be automatically recognized without the operator having to read the figures, so the board drilling is suitable for NC tape. The data for creating the NC tape can be input to the NC tape creating device in a short time, and the time required to create the NC tape can be shortened. Further, since the data input for creating the NC tape is automatically performed without human intervention, data input errors and the like are eliminated, and the NC tape can be created accurately. As described above, according to the position recognition device, it is possible to extract data for creating NC tapes, etc., quickly, accurately, and easily.
