Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a design construction support system for supporting construction of a design suitable for an image desired by a user.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a system that simulates a situation when a user wears when designing a design such as glasses or clothes. This is a tool for displaying images that combine several designs with a user's face photo and body shape, and judging whether or not it is in line with the wishes. Also, for the initial search from the database, the relationship between the image keyword and design is created in advance as a database, the system accepts the image keyword as the user's request, and the design conforms to the image keyword. It is common to search for a database from a database. At this time, the database is either authorized or created from a questionnaire or the like. Further, Japanese Patent Application Laid-Open Nos. 7-200653, 4-266165, and 3-201068 propose a technique for changing a design drawing so as to match an input image keyword.
[0003]
[Problems to be solved by the invention]
The problem with these prior arts is that they do not consider design interactivity. Since design is originally related to each other and an image is constructed, the effect of the combination is a very important issue. Therefore, it is desirable to provide a system that can provide design support in consideration of design interaction.
[0004]
Incidentally, in Japanese Patent Laid-Open Nos. 8-221462 and 5-20407, inference means capable of taking into account the interaction between a plurality of design elements are disclosed. There is no proposal for a system that has a function to reevaluate and reflect it in the rule base, or to give advice in a better direction. Therefore, an object of the present invention is to provide a design construction support system capable of providing support such as showing more preferable alternative candidates from the difference calculation with the evaluation of the system while allowing a user to freely change the design. . A further object of the present invention is to provide a design construction support system adapted to the sensitivity of individual users by accumulating the results of design changes by the users.
[0005]
[Means for Solving the Problems]
In the design construction support system of the present invention, in order to solve the above-described problem, as shown in FIG. 1, the image information of a plurality of design elements constituting the design object and the information for retrieving the image information Can be input as a combination of information expressing a subjective image and information on a predetermined design element that is an objective constraint condition. In order to realize the image desired by the user based on the information input from the condition input unit 2, including the rule input unit 2 and a rule base that stores rules relating to image formation by the interaction of a plurality of design elements A search unit 3 for searching the necessary undecided design elements from the image database 1 and a design requirement already entered from the condition input unit 2 And an image composition unit 4 that creates an image information of a design target by synthesizing an undecided design element read from the image database 1, and displays the image information of the design target created by the image composition unit 4. The display unit 5, the evaluation input unit 6 for inputting the user's evaluation regarding the design target image information displayed by the display unit 5, and the user's evaluation input by the evaluation input unit 6 match the user's desire. A design modification unit 7 for automatically or manually changing a design element that has not yet been determined in a direction, and a modification for outputting, as modification support information, a result of comparing the changes made by the design modification unit 7 with the rule base of the search unit 3 And a support unit 8. Moreover, it is preferable to provide the personal database 9 for accumulating the rule for adapting the rule base which the search part 3 has to each user based on the change track record by the design correction part 7. FIG.
[0006]
The design correction unit 7 may perform image operations such as color change and enlargement / reduction with respect to the image information stored in the image database 1. The evaluation input unit 6 for inputting the user's evaluation may determine the user's evaluation from physiological information such as the user's brain waves. Further, the information expressing the user's subjective image may include linguistic information including adjectives or multimodal information such as user gestures, hand gestures and facial expressions.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an explanatory diagram showing the overall configuration of the design construction support system of the present invention. In the figure, reference numeral 1 denotes an image database, in which image information of a plurality of design elements constituting a design object and information for retrieving the image information (so-called tag information) are linked and stored. The image database 1 is realized as a data file on a hard disk of a computer, for example. A condition input unit 2 is configured by using a computer input device such as a keyboard and a mouse, and is a means for inputting a user's desired condition regarding a setting target. The user's desired conditions that are input include information that expresses the user's subjective image and information on design elements that are objective constraints. A search unit 3 includes a rule base for searching the image database 1 for insufficient design elements necessary to realize an image desired by the user in consideration of the interaction between a plurality of design elements. ing. For example, a database describing the relationship between design elements and image keywords as disclosed in Japanese Patent Application No. 11-13532 can be used as the search unit 3.
[0008]
Reference numeral 4 denotes an image composition unit, which is a design object by synthesizing the design elements input from the condition input unit 2 and already determined as constraint conditions and the design elements that can be changed read from the image database 1. This is means for creating image information. The image composition unit 4 is realized by software or hardware using computer graphic technology. Reference numeral 5 denotes a display unit, which is composed of a computer monitor screen or the like, and displays design target image information created by the image composition unit 4. An evaluation input unit 6 is a device that determines and inputs a user's evaluation regarding the image information of the design target displayed on the display unit 5 by voice recognition, electroencephalogram analysis, facial expression analysis, or the like. For example, by interpreting that the α wave of the electroencephalogram is satisfactory and the β wave is unpleasant, it is possible to know whether or not the user's design is acceptable.
[0009]
Design modification unit 7 is a means for automatically or manually changing design elements when the user's evaluation input by evaluation input unit 6 does not match the user's wishes. For example, by reading other design elements from the image database 1 or performing image operations such as color change and enlargement / reduction on the image information of the design elements read from the image database 1, user preferences can be obtained. It is close. Reference numeral 8 denotes a correction support unit, which has a function of providing support and advice such as showing a more preferable alternative candidate from the difference calculation by comparing the changes made by the design correction unit 7 with the rule base of the search unit 3. ing. Reference numeral 9 denotes a personal database, which accumulates rules for adapting the rule base of the search unit 3 to individual users based on the results of the change when the design correction unit 7 makes a change. is there. As a result, it is possible to realize a system adapted to the sensitivity of individual users.
[0010]
FIG. 2 shows an example of a screen displayed on a computer monitor when a mouse is used as the condition input unit 2. For example, if the design target is a kitchen, the user's subjective question such as “Adorable image” or “Luxury image” will be given to the question “Q1. Choose a word that expresses the image of the kitchen you want to create”. Evaluation terms including adjectives representing evaluation are available as options. Next, in response to the question “Q2. Please enter the one whose design is determined in the kitchen”, the “door pattern” of the cabinet is divided into three patterns: “flower pattern”, “striped pattern”, and “wood pattern”. Options are prepared, and three options of “L type”, “I type”, and “M type” are prepared for the “shape” of the counter. Furthermore, three options “4 tatami mats”, “6 tatami mats”, and “8 tatami mats” are prepared for the question “Q3.
[0011]
For example, in the condition input unit 2 shown in FIG. 2, the desired conditions are “light image”, “door pattern” of the cabinet is “wood”, “shape” of the counter is “L”, and floor plan is “4”. When “tatami mat” is selected, the search unit 3 determines the design elements already entered by the user (“door pattern” of the cabinet is “wood”, “shape” of the counter is “L”, and kitchen layout is “4”. The final combination of design elements is determined so as to realize a “light image” using “tatami” as a constraint. FIG. 3 illustrates an example of the determined design element set and an image of a kitchen constituted by the combination of these design elements. If the presented image diagram is unsatisfactory, editing such as changing the color of the door or replacing the cabinet is performed based on the presented image diagram. In the editing operation, a technique is used in which a plurality of alternative candidates are displayed by clicking a portion to be changed in the displayed image diagram with a mouse, and a user's preference is selected from among them.
[0012]
The result of this change is evaluated by the correction support unit 8 based on the rule base of the search unit 3. For example, the degree of the “light blue image” of the kitchen after the change is evaluated to be 8 in the 10-level evaluation, and the result is notified to the user. In addition, we will give advice on how to make a kitchen with a better image as a system. In this example, if you think based on the current design in order to change the image with a bright image level of 8 to 10, you should give a message that you should put a window in front of the sink. is there.
[0013]
In the embodiment, the menu-type item selection device is exemplified as the condition input unit 2, but the present invention is not limited to this, and for example, a method such as gesture recognition or facial expression recognition using an image obtained by photographing the user is used. The user's wishes can be known without relying on menus or words.
[0014]
【The invention's effect】
According to the first aspect of the invention, it is effective to embody a design image of a user that is not clarified, and in particular, a rule base that takes into account the interactivity of design elements is used. As a result, it is possible to support design design considering the relevance of the entire design. Further, even if a certain design element is included as a constraint condition, image calculation is performed in balance with the design element, and a design that realizes the user's wish as a whole becomes possible. Furthermore, even when the design element is changed by the user's own hand, it is possible to provide support such as showing a more preferable alternative candidate from the difference calculation with the evaluation of the system. According to the second aspect of the present invention, the rule base of the search unit is improved to be changed to a personal rule base, thereby enabling evaluation according to individual users.
