JPH05303616A - Method for selecting correction object for correcting graphic database - Google Patents

Abstract

PURPOSE:To readily select the object to be corrected without requiring special knowledge by dividing the object into elements at its display and taking the element as an object when the result discriminating the right or wrong of the selection is correct. CONSTITUTION:When an operator selects the menu BR, for example, the video display is changed. As the display includes a part to be corrected, the selected operation is judged to be correctly performed. An object should be branched into OL and OR and the object OR is designed to include objects ORR and ORL. In this case, when the operator selects the menu BR again, the object ORR is selected but a part to be corrected (object ORL) is not included so that the selected operation is judged to be incorrectly performed. In this case, by selecting the R one-rank higher than the menus BR and BL, the upper object OR including the object ORR is displayed again on the video display device. When the menu BL is selected, the object ORL is properly selected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention does not require an operator to have knowledge of the structure of a database to be modified when modifying a graphic database having a tree structure. The present invention relates to a modification target selection method for modifying a graphic database that allows a target (object) required for modification to be easily selected without performing the above.

[0002]

2. Description of the Related Art Conventionally, as a method of selecting an object used in a technical field such as CAD, a method of referring to each target object by an individual assigned name, number or the like, or an image There is a method of picking with a light pen on the display screen of.

[0003]

However, in the case of the conventional method, when the target database becomes large-scale, the former method is troublesome to operate, and the latter method is Whether the operator of the light pen intends is an object designated by the tip of the light pen or a higher-level object (that is, a parent object) including the object as one element. There are problems such as inability to be identified, and when two or more objects are overlapped, it is unclear which object is designated.

The present invention has been made to solve such a problem, and a parent object is branched into two child objects, and each child object is branched into two grandchild objects. It is an object of the present invention to provide a correction target selection method for correcting a graphic database having a so-called tree structure.

[0005]

A method of selecting a correction target for correcting a graphic database according to the present invention is a digitizer having a menu represented by one upper element and two lower elements obtained by dividing the upper element. A method for selecting a correction target of a graphic database having a tree structure, which is performed by using a general-purpose computer including as input means and a visual field simulating device including a certain predetermined image display device, the first target being the first target. And a first step of displaying the image on the image display device by dividing it into two elements, and one of the first and second elements based on the designation of one of the two lower elements in the menu. The second step of determining whether or not the selection is successful, and if the determination result in the second step is not valid, the process returns to the first step, and if it is valid, one of the first and second elements is set And the A third step of displaying on said video display apparatus is divided into elements, said third and fourth based on one of the specified one of the two sub-elements in the menu
The fourth step of judging whether or not one of the elements is selected, and if the judgment result in the fourth step is not valid, the procedure returns to the third step. Fifth one of the four elements for the time being
And the determination result in the second or fourth step is correct, and only the correction target is displayed on the image display device, the correction target selection operation is finished.
And the steps of.

[0006]

In the present invention, the current correction target is divided into the first and second elements, one of them is selected and the third and fourth elements are selected, and one of them is selected. For the time being. As a result, the operator can easily and surely select the target to be modified, without having special knowledge about the structure of the database to be modified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an apparatus to which the present invention is applied. In the figure, 1 is a general-purpose computer, which has input means such as a terminal (including a keyboard) 11, a digitizer or a tablet (here, a menu 121 is attached) 12, a mouse 13 or a joystick 14. It is attached. Reference numeral 2 is a visual field simulation device, which is connected to the general-purpose computer 1 side in real time, and includes a video generation device 21 and a video display device 22. The database of objects displayed on the side of the visual field simulator 2 is created by the general-purpose computer 1 based on the required input data from the input means, and the created database is the visual field in which it should be used. When an image based on the created database is transmitted to the simulator 2 side and an image based on the created database is obtained on the image display device 22 and any inconvenience is found by observing the image, the created database is displayed. On the other hand, the required correction operation is immediately performed.

FIG. 2 is an illustration showing the layout of the menu 121, where R designates an object (eg, parent object) corresponding to the tree-structured graphic database, and B _L
And B _R specify branching of the object selected by R into one of left and right parts.

FIG. 3 is a view showing an example of an object selection process in the present invention. First, as shown in FIG. 3A, it is assumed that an object O exists and this object O is branched into an object O _L and an object O _R , and a black portion in the branch O _R is corrected. Shall be the part to be done. like this,
The image of the object O shown in FIG. 3A is displayed on the image display device 22 in the visual field simulating device 2, and the operator who performs the necessary correction work includes the object O at this stage. It is assumed that there is no particular knowledge about the objects O _L and the objects O _R that are present. In such a state, when the operator selects B _R in the menu 121 by trial and error, the display of the video display device 22 is changed as shown in FIG. 3B, and this display is corrected. This selection operation is identified as successful because it contains the portion to be done. And in this FIG.3 (b), the object O _R is made to include the object O _RR and the object O _RL . At this stage, when the operator selects B _R in the menu 121 again, the object O _RR is selected as shown in FIG. 3C, but this object O _RR is corrected. It is identified that this selection operation was incorrect because it did not contain the part to be considered (ie the object O _RL ). At this time, the operator selects the R immediately above B _R and B _L in the menu 121 to display the higher-level object O _R including the object O _RR again on the video display device 22. That is,
It will be returned to the state shown in FIG.
Here, when the operator selects _BL in the menu 121 different from the selection in the previous stage, the object O _RL is selected and displayed as shown in FIG. _3D . Then, this object O _RL corresponds to the portion to be corrected, and in the end, the desired object selection is properly made. Incidentally, in this process, the change from the state shown in FIG. 3C to the state shown in FIG. Alternatively, for example, the operation may be performed in a one-step operation.

[0010]

As described above, according to the present invention, it is not necessary for the operator to have special knowledge about the structure of the database to be corrected, and the operator should make corrections. This has the effect of easily and surely selecting the target.
