DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates is displayed on the display screen of the display device, it relates to an image processing system having a function of performing a displacement process of the assembly comprising a plurality of parts, in particular,
Or move many combined assembly of parts on the display screen, relates to an image processing system suitable for high speed processing when causing the displacement of such change the posture.

[0002]

2. Description of the Related Art When an image of an assembly composed of a plurality of parts is displayed by using computer graphics technology, for example, image data for displaying an image of a part which is a component of the assembly is used. An image of the assembly is generated and displayed. When displaying such an assembly, the display position or the attitude of the assembly may be changed on the display screen in some cases. Move it,
Displacement processing when changing the posture is required. In this case, it is necessary to display such that the displayed assembly is displaced integrally. For this reason, it is necessary to define the connection relation of each component constituting the assembly.

Conventionally, such a definition has been defined for each part according to the structural property that an assembly is a set of parts.
This is performed by generating data indicating a connection relationship between the component and another component connected thereto. Therefore, when the assembly is displaced, for example, when the assembly is moved by a drag operation on the screen, the following processing is performed. First, when the pointer is pointed to any of the components making up the assembly, the connection relationship defined for the pointed first component is checked, and further the second connection that is found to be in the connection relationship thereby is found. The connection relation is sequentially searched for each of the parts constituting the assembly, for example, the part is examined next, and then the third part in the connection relation with the second part is examined. Figure out. Next, following the drag operation on the pointed first component, the same movement operation is performed on the first component as well as on all the components that are integrated with the first component. That is, a coordinate conversion process of the image data of each component is performed according to a change in the position of the pointer, and drawing is performed based on the new coordinates. This is performed at predetermined time intervals according to the moving speed of the pointer. Thereby, it is displayed as if the assembly is moving on the screen according to the movement of the pointer.

[0004]

As described above, according to the conventional image processing technique, even an assembly composed of a plurality of parts can be moved as a whole by grasping all the constituent parts. Can be displayed.

However, when the number of components is large, it takes a long time to sequentially search for the connection relationship of each component having a relationship of moving together with the pointed component from the pointed component. For this reason, in the case of an assembly having a large number of parts, processing for realizing rapid displacement is not easy, and
In order to make this possible, a processor having a higher processing speed is required, and there is a problem that hardware restrictions are imposed.

On the other hand, there is a technique disclosed in Japanese Patent Application Laid-Open No. 64-80960 as a technique relating to a printing plate-making layout apparatus for performing a layout in accordance with the contents of a layout sheet. In the technique disclosed in this publication, a graphic element subordinate to an arbitrary graphic element in a graphic layout displayed on a display means by a layout drawing means and group information indicating its dependencies are instructed and input from the dependency information input means. Then, the registration unit registers the graphic element dependent on any graphic element in the input graphic layout and the group information indicating the dependency thereof in the graphic information storage unit, and the change information input unit transmits the group information to the display unit. When an arbitrary graphic element in the graphic layout drawn on the display means and its change information are instructed by the change information input means, the graphic element changing means deletes the graphic element having the group information for the graphic element. While searching from the graphic information storage means,
The instruction unit is caused to collectively change and draw the retrieved graphic element group based on the instruction-input change information. That is, in this technique, a table is created in which graphic numbers are hidden for each component and group numbers are associated as information indicating groups to which each part belongs. And when the parts are specified,
Search the table to find the group number to which the part belongs.

In the present technology, it is necessary to search for a designated part number from the top of the table at the time of a search, and check a corresponding group number. In this case, in general,
You need to search half the number of rows in the table. Then, the table is searched to find all parts belonging to the found group. At this time, it is not always the case that all data of the group is continuously included. Therefore, it is necessary to search until the end of the table. The number of searches is, for example, (number of parts / 2) + number of parts. Therefore, there is a problem that the amount of processing is large and it takes time to grasp all the components that are integrated with the designated component.

According to the present invention, in an assembly composed of a plurality of parts, a part to be moved integrally can be grasped in a short time regardless of which part is pointed, and the assembly can cope with rapid displacement of the assembly. Ru near to provide a technology that can be.

I do.

The input device 200 includes a keyboard 210,
And a mouse 220. Of course, it is not limited to this. Here, the mouse 220 is, for example, a display screen 310.
Pointer 320 (see FIG. 2) displayed on (see FIG. 2)
Can be used when performing various processing operations such as a drag operation as a pointing operation for specifying an image and an operation for moving an image.

The display device 300 includes, for example, a display such as a CRT or a liquid crystal display, and a driving device for driving the display, and can display images. Various images drawn by the processing device 100 are displayed on the display screen 310.

The storage device 400 is constituted by, for example, a hard disk device. The storage device 400 includes a CPU
The program executed by 110 and various data are stored. The program is system program 4
10 and an application program are stored.
At least an image processing program 420 is stored as an application program. The image processing program 420 causes the CPU 110 to perform processing for generating an image of a part, an assembly, or the like based on the shape definition data and writing the image to the video memory 130. The various types of data include component shape definition data 430 that defines the shape of the component.
And the display position data 440 indicating the display position of each part on the display screen, and the connection state expression data 450 expressing the connection state of the parts in the assembly. Integral relation expression data 460 indicating that there is an integral relation to be displaced in cooperation with each other is stored.

The shape definition data 430 includes, for each part, information for specifying the part, for example, a part code,
Identification data such as a part name and a part number, vector data defining its three-dimensional shape, connection position data indicating a connection position when connected to another part, and color, texture, and mass of the part Is defined at least. The connection position data includes, for example, data indicating positions of notches for insertion, screw holes, through holes, and the like.

The display position data 440 is, for each part,
It has data indicating where it is displayed on the display screen, and data defining the reception area when the pointer 320 points. The display position is obtained, for example, by converting vector data indicating the shape into coordinates corresponding to the display position on the display screen.

As the connection state expression data 450, for example, as shown in FIG. 3, for each of the parts A to D and for each of the screws 1 to 4, data indicating other parts which are connected to each other. 451-458. These are stored in a file for each component. Part A
As shown in FIG. 2, since the parts B and C are connected as shown in FIG. 2, as the data indicating this, the connection destination data B and the connection destination data C are stored in the file of the connection state expression data 451. Is stored. As the data, identification information for specifying the components B and C is stored. Similarly, for the component D, connection destination data B and connection destination data C are stored in the file of the connection state expression data 454. On the other hand, part B
For screw 1, screw 3 and screw 3
Then, the part B is connected to the parts A and D to be connected, and information indicating the connection data A and D is stored in the file of the connection state expression data 452. Similarly, for the part C, the screws 2 and 4 and the parts A and D to which the part C is to be connected are connected as data to be connected. D is stored.
In addition, for the screws 1 to 4, data indicating the parts to which each of the screws is connected is stored in each file of the connection state expression data 456 to 458.

As the connection data, for example, FIG.
And the connected data is recorded, for example, as shown in FIG. 4B. The connection data 450 includes a connection component name 4501 indicating a component to be connected and a connection state 450
2, that is, information indicating whether the connection is in progress or disconnection, information indicating the connection type 4503, for example, whether the connection is a screw connection or other connection, and information indicating the name of the screw used 4504 when a screw is used. Is recorded. Connection part name 450
As 1, for example, a name that uniquely identifies a component is used instead of a general component name. Specifically, symbols, codes, names, and the like uniquely determined for all parts are used. As connected data, a connected component name to which the component is to be connected is recorded.

The integral relationship expression data 460 indicates that, when one of the components is displaced, the other components are integrated with one of the components (reference component) which is displaced in accordance with the displacement. Integral relationship definition data that defines the relationship, and for each of the other parts,
There is integrated relationship definition reference data including information for referring to the integrated relationship definition data. The reference part is one part selected from a group of parts constituting the assembly 10 at that time. This component can be automatically selected by the system, but can also be selected from the component group via the input device 200.

As the integral relation definition data, for example, as shown in FIG. 5, when the reference part is a part A, the parts A, B, C and It has information indicating D and information indicating a screw which is a part used for connection between them, and these are stored in the file of the integrated relationship definition data 461 as shown in FIG. On the other hand, other parts B and C
And D and the screws 1 to 4, the information of the connection destination A indicating the component A, which is the reference component, corresponds to each of them, as shown in FIG. 468 are stored in corresponding files. For example, a pointer indicating the address of the integrated relationship definition data 461 may be stored together with or instead of specifying the specific component name of the reference component as the connection destination.

Thus, when the part A is pointed by the mouse 220, all the parts to be displaced integrally with the part A can be immediately identified by the integrated relation definition data without searching. Also, when a component other than the component A, for example, the component C is pointed by the mouse 220, for example, as information for reference included in the integrated relationship definition reference data, It is possible to access the integrated relationship definition data using the information for specifying the connection destination.
Therefore, even if there are many components, it is not necessary to search for a connection partner for each component, and a component to be quickly displaced integrally by one search is specified. Therefore, it is possible to respond to a drag operation or the like at high speed.

The integral relation expression data is rewritten as appropriate according to the degree of assembly of the assembly 10. For example, when the component D is separated, the information of the connection destination D is deleted from the integrated relationship definition data shown in FIG. As for the connection destination data relating to the component D, the information of the connection destination A is deleted. As a result, the assembly composed of the parts A, B, and C and the part D are separated from each other, and even if any one of the parts is pointed, the data is not referred to the other. Therefore, both are displaced independently.

An assembly comprising parts A and B,
If there is an assembly consisting of parts C and D, FIG.
In the integration relationship definition reference data shown in FIG.
Information indicating the screws 1 and 3 is stored. Similarly, information indicating the component C and the screws 4 and 2 is stored in the connection destination data for the component D.

Here, when an instruction to combine and assemble an assembly using the component A as a reference component and an assembly using the component D as a reference component is given, one of the components A and D is given. The connection destination data of the other component (eg, component A) is added to the integration relationship definition data of the component (eg, A) serving as the reference component. Then, the connection destination data for the components D and C and the screws 4 and 2 are all rewritten to the integrated relationship definition reference data indicating that the component A is the connection destination. Thereby, parts A to D
Have an integral relationship, so that, even if any component is moved, all other components that are integral with the component are also moved.

In the above description, the connection state expression data 450 and the integrated relation expression data are stored in the form of a file for each component, but the present invention is not limited to this. For example,
You may make it memorize | store in a table format.

Next, the operation of this embodiment will be described with reference to FIG. Here, as shown in FIG. 2, the assembly 10 is defined in advance, and the display device 30
0 is displayed on the display screen 310. As shown in FIG. 2, the image of the assembly displayed in this manner is subjected to a drag operation by the mouse 220 and subjected to image processing in the processing device 100, whereby the image is processed along the broken line toward the position of the two-dot chain line. A case in which an image is displayed while moving it will be described. The following processing is executed by the CPU 110 according to the image processing program.

First, the presence / absence of a point instruction by the mouse 220 is detected (step 1111). If there is a point, the position of the pointer 320 is detected, the position of the pointer 320 is compared with the positional relationship between the displayed parts, and the pointer 320 points to any part of the assembly 10. Is determined (step 111
2). If any part is pointed, the part is extracted (step 1113). The extraction process can be performed by searching the display position data 440 stored in the storage device 400 using the display address of the pointer as a key.

Next, it is determined whether the extracted part belongs to the reference part among all parts belonging to the assembly at that time (step 1114). Here, if the reference component is not the reference component, the reference component is detected by referring to the data related to the pointed component in the integrated relationship definition reference data (462 to 468). Here, it is assumed that the address of the integrated relationship definition data 461 in FIG. 5A is obtained (step 1115). If the extracted component is a reference component, or if the address of the integrated relationship definition data 461 is acquired as described above, the integrated relationship definition data 461 is referred to (step 1116). Thereafter, the display mode of the display image of the assembly 10 including the pointed product is changed (step 1117). For example, the display color is changed to be displayed in a display mode generally used to indicate that an object is in a selected state.

Next, it is determined whether or not dragging is being performed (step 1118). When the drag operation is released, the change of the display mode is restored (step 1123).

If the drag is being performed continuously, the current position of the pointer 320 is detected (step 1).
119). That is, the display address of the display position of the pointer 320 on the screen is obtained. Next, the pointer 320
The display address of the assembly 10 whose display mode has been changed is calculated based on the display position of
Display at the calculated display position on the display screen (step 1
120, 1121). These processes are repeated until the drag is completed (step 1122).

Thereafter, a process of undoing the change of the display mode is executed (step 1123).

Although the example in which the assembly 10 is moved on the display screen 310 has been described above, the present invention is not limited to this. For example, the present invention can be applied to various displacements such as rotating the assembly and changing the orientation three-dimensionally. In addition, processes such as enlargement and reduction of the display image of the assembly can be similarly performed using the integrated relation expression data.

When the display mode of the pointed assembly is changed, the display mode may be changed between the reference component and other components. By doing so, it is possible to easily know which component is set as the reference component.

Next, a process of editing the integrated relation expression data used in the present invention will be described with reference to FIG. This process is executed in conjunction with the process of editing the assembly. This is also processed by the CPU 110.

An assembly editing process is performed, and when the status of the assembly is changed by the editing, a process of rewriting the connection state expression data 450 in accordance therewith is performed (step 2111). That is, the information indicating the connection state is rewritten for the parts whose connection states have been changed, such as newly added parts, removed parts, parts whose connection relations have been changed, and the like. For example, of the connection data shown in FIG. 4 that indicates the connection state, the connected data is “connecting” and the disconnected data is “separating”.
Set the state for each.

Next, it is checked whether or not the configuration of the assembly has been changed by referring to the connection state expression data (step). When there is a change, the integrated relation expression data 460 is rewritten according to the mode of the change (steps 2113 to 2116).

That is, it is checked whether there is a part separated from the assembly (step 2113). In that case, first, the integral relation expression data 460 of the assembly (separation source) is rewritten (step 2114a). In this case, when the separated component is the reference component, the specification of a new reference component is accepted or according to a predetermined rule.
A new reference part is set, and the entire part is rewritten with the reference part as the center. On the other hand, when a part that is not the reference part is separated, the part related to the part of the integrated relation definition data is rewritten, and the contents of the integrated relation definition reference data relating to the separated part are deleted. Next, a reference component is set for the separated component, and data at the separation destination is rewritten (step 21).
14b).

Further, it is checked whether or not there is an addition (step 21).
15) In some cases, data indicating the connection state of the corresponding component is added to the integrated relationship data 460 (step 2116).

Thereafter, it is checked whether there is a request for changing the reference part (step 2117). If there is a change request, the integrated relation expression data 450 is rewritten (step 2).
118). That is, reference component designation for a different component from the past is received from the input device 200, and the integrated relationship definition data defined for the reference component up to that point is rewritten for the newly designated component. In addition, the integrated relation definition reference data is rewritten for parts other than the other reference parts.

In this way, the integrated relation expression data is edited. According to the edited result, the storage device 400
Is updated. Thereafter, in the display processing for the displacement of the image, the changed integrated relationship expression data is referred to.

In the above-described example, when the reference component is changed, the current display mode of the reference component may be changed. This makes it possible to visually check which part is the reference part.

Next, FIG. 8 shows another example of the integrated relation expression data. The integrated relationship expression data shown in FIG. 8 includes integrated relationship definition data 461a having, as connection information, a pointer to definition information of each component having an integrated relationship with component A, which is a reference component, and definition information for each component. Integration relationship definition reference data 462a having a pointer to connection information of the component (the reference component A) to which the component is connected,
463a, 464a... In the example of FIG. 8, the connection state data of the components B, C, and D other than the reference component A is included in the definition information of each of the components B, C, and D together with the integrated relationship definition reference data.

In the example of FIG. 8 as well, when the part A is pointed, the integral relation definition data 461a can be directly referred to. If other parts are pointed, the integration relation definition reference data 4
By referring to the corresponding data among the data 62a to 464a, the integrated relationship data definition data 461a can be found according to the pointer indicated by the data, and the data of the file can be referred to. Therefore, the number of searches is
Only once, regardless of the number of parts.

As described above, the present invention has the effect of speeding up the processing when displacing an assembly composed of a plurality of parts.
Therefore, for example, the present invention can be applied to a system for performing education and training on the assembling and disassembly of a device using three-dimensional graphics. In this case, it is possible to realize a system capable of performing a simulation of assembly and disassembly at high speed for a set of a plurality of parts.

[0059]

According to the present invention, it is possible to grasp in a short time a part to be integrally moved, regardless of which part is pointed, in an assembly composed of a plurality of parts. Therefore, it is possible to cope with rapid displacement of the assembly.
