  FIG. 2 shows an example of a functional block of a parts catalog creation function for creating a parts catalog using 3D_CAD data.

  In the figure, a catalog creation unit 20 creates part catalog data based on data stored in a 3D data storage unit 21 and a parts list storage unit 22 formed in a storage device (not shown). save.

  Here, the 3D data storage unit 21 is a database holding 3D_CAD data used for creating a catalog. Further, the 3D_CAD data holds shape information in units of individual parts constituting the product, and is stored in a state where these parts are assembled.

  The parts list storage unit 22 is a database describing a list of parts (replaceable parts) to be included in the catalog. In the parts list, part names, part ordering numbers, and the like are held in a unit unit of the product.

  The catalog creation unit 20 stores the 3D_CAD data stored in the 3D data storage unit 21 among the parts registered in the parts list stored in the parts list storage unit 22 in the 3D data storage unit 21. With reference to the contents, the image data (2D data) stored in the image data storage unit 24 is compensated and input by the image compensation unit 25 if the 3D_CAD data is not stored in the 3D data storage unit 21. In addition, for the image data input by the image compensation unit 25, the position information input from the position information compensation unit 26 is used as the position information used when displaying the part.

  Here, the image data storage unit 24 holds, in advance, an image photographed with a digital still camera or an image created by an illustration for a part that is described in the parts list but does not exist as 3D_CAD data. It is a database.

  In addition, the image filling unit 25 designates an image (file) in the image data corresponding to a part that is described in the parts list but does not have 3D_CAD data, and gives it to the catalog creating unit 20.

Catalog data composed of (from a plurality of viewpoints) is stored for each part.

  Also, the image showing the assembly position of the part highlights the part so that the assembly position of the target part can be seen in the image of the unit indicating the product or part of the product (when created from 3D data) Alternatively, a rectangular area indicating the assembly position of a part or a rectangular solid surrounding the part is highlighted.

  The catalog browsing unit 27 displays the contents of catalog data stored in the catalog storage unit 23 created by the catalog creation unit 20. In addition to searching by part name, it is possible to search for a part by specifying an area on the part assembly state diagram.

  FIG. 3 shows an example of the configuration of the catalog creation unit 10.

  In the figure, the model data management unit 21 includes part shape information representing the part shape of each part that constitutes the device with respect to a three-dimensional model prepared in advance by the 3D data storage unit 11 and the parts list storage unit 12. 3D model information including at least the entire shape information representing the assembled state of each part is stored and managed, the entire shape information SF and the part shape information SP are catalog data creation processing unit 22, and the component screen area calculation The data is passed to the processing unit 23.

The catalog data creation processing unit 22 uses the entire shape information SF and each part shape information SP received from the model data management unit 21 and the line-of-sight direction PE and zoom parameter PZ received from the input / output device 3 to obtain the entire image IZ and The entire image IH with highlight, the single image IT, and the boundary information IK corresponding to each part are created and passed to the catalog storage unit 13.

  Here, the line-of-sight direction is given by polar coordinates α and β in a three-dimensional space. At this time, the relationship between the XYZ orthogonal coordinate system of the three-dimensional model and α and β is shown in FIG. The zoom parameter is given as a numerical value from 0.0 to 1.0, and the larger the numerical value, the larger the zoom image.

The whole image IZ is the whole image of the three-dimensional model displayed with the designated zoom parameter, and the whole image with highlight IH is the focus of the whole image of the three-dimensional model displayed with the designated zoom parameter. This is an image obtained by highlighting the displayed part shape (displayed with a specific display attribute), the single image IT is an image of only the part shape of interest, and the boundary information IK is the designated zoom parameter. In the entire image of the three-dimensional model displayed in (3), the information is a line that is a boundary between the region occupied by the focused part and the region that is not.

Further, the component screen area calculation processing unit 23 executes the following three steps for each line-of-sight information PE received from the input device 3 to create the component screen area information PM and passes it to the catalog storage unit 13.

  First, the screen of the two-dimensional image when the assembly shape is displayed in the line-of-sight direction is divided into several rectangular areas in a grid pattern, and an ID (screen area ID) is assigned to each of the divided areas. At this time, the number of vertical areas and the number of horizontal areas are determined in advance in the system (step 1).

  Next, for each part constituting the three-dimensional model, it is geometrically calculated in which ID region in step 1 the point on the three-dimensional space expressing the shape of the part is located. This is performed for all points representing the shape of the part. At this time, an ID (part ID) is assigned to each part, and the result is stored in the memory for each part ID in a format as shown in FIG. 4B (step 2).

Then, the result of step 2, sort by screen area ID, and creates a part screen area information P M of the table format as shown in FIG. 4 (c).

  Therefore, when browsing the catalog data created by this system, for example, by specifying one point on the assembly image by the input device, calculating which screen region ID the specified point is indicated by, The component ID corresponding to the corresponding screen region ID is extracted from the component screen region information PM, and the corresponding highlight assembly image and single image can be determined as the selected part.

  As described above, when browsing the catalog data, by specifying any one point on the screen, it becomes possible to narrow down the parts near the specified point from the whole part, and the processing performance is low It becomes possible to withstand practical use even on a computer.
