Abstract

To enable decision of the arrangement of a member to be supported.SOLUTION: A design system comprises: an arrangement part which generates an arrangement image in which one or more images of plural types of members are arranged for each type; an evaluation part which calculates an evaluation index value of the arrangement image for a visual evaluation index about the image; and an arrangement candidate extraction part which decides whether or not the arrangement image is adopted as a candidate image indicating a candidate of arrangement of the member by using the evaluation index value.SELECTED DRAWING: Figure 1

Claims

1. If the arrangement image in which images of multiple types of members are arranged, with one or more images of each type, uses four or fewer types of members, the arrangement unit stores the unit pattern of the unit that shows the arrangement pattern of the types of members, and whether or not connections between units are possible, as an arrangement rule for the unit, and generates the arrangement image by combining units according to the arrangement rule to design the arrangement of the types of members. If there are five or more types of members, the arrangement unit randomly determines the arrangement of the types of members and generates the arrangement image. Regarding visual evaluation metrics for images, an evaluation unit calculates evaluation metric values ​​for the arranged images, An arrangement candidate extraction unit that uses the aforementioned evaluation index value to determine whether or not to adopt the arrangement image as a candidate image showing a candidate arrangement of the member, A design system equipped with these features.

2. The arrangement candidate extraction unit excludes arrangement images from the candidate images in which images of the same type of member are adjacent. The design system according to claim 1.

3. The arrangement unit selects the units to be arranged such that the types of members placed at the center of adjacent units are different. The design system according to claim 1 or claim 2.

4. The arrangement section generates a new unit by partially overlapping multiple units such that members of the same type overlap between them. The design system according to any one of claims 1 to 3.

5. The system further comprises a visual feature image generation unit that generates a visual feature image representing the visual feature quantities related to each portion of the aforementioned arrangement image. The evaluation unit calculates the evaluation index value based on the visual feature image. The design system according to any one of claims 1 to 4.

6. The system further comprises a schematic image generation unit that generates a schematic image showing the binarized values ​​of the visual features related to each portion of the aforementioned arrangement image. The evaluation unit calculates the evaluation index value based on the schematic image. The design system according to any one of claims 1 to 5.

7. The system further includes a gaze feature generation unit that generates gaze features indicating an estimated degree of visibility for each portion of the aforementioned arrangement image. The design system according to any one of claims 1 to 6.

8. The gaze feature generation unit generates a gaze feature image that shows the gaze features in the form of a heatmap associated with the arrangement image. The design system according to claim 7.

9. The system further includes a visual feature and gaze feature generation unit that generates visual feature and gaze feature obtained by performing calculations for each part of the aforementioned arrangement image, using a visual feature image that shows the visual feature quantities related to that part, and a gaze feature image that shows an estimated value of the degree to which that part is visible. The design system according to any one of claims 1 to 8.

10. The design system If the arrangement image, in which images of multiple types of components are arranged with one or more of each type, uses four or fewer types of components, the arrangement pattern of the units that show the arrangement pattern of the component types, and whether or not connections between units are possible, are stored as arrangement rules for the units, and the arrangement of the component types is designed by combining units according to the arrangement rules to generate the arrangement image. If there are five or more types of components, the arrangement of the component types is determined randomly to generate the arrangement image. Regarding the visual evaluation metrics for the images, the evaluation metric values ​​for the arranged images are calculated. Using the aforementioned evaluation index values, it is determined whether or not to adopt the arrangement image as a candidate image showing a candidate arrangement of the member. A design method that includes this.

11. On the computer, If the arrangement image, in which images of multiple types of components are arranged with one or more of each type, uses four or fewer types of components, the arrangement pattern of the units that show the arrangement pattern of the component types, and whether or not connections between units are possible, are stored as unit arrangement rules, and the arrangement of the component types is designed by combining units according to the arrangement rules to generate the arrangement image. If there are five or more types of components, the arrangement of the component types is randomly determined to generate the arrangement image. Regarding the visual evaluation metrics for the images, the evaluation metric values ​​for the arranged images are calculated, Using the aforementioned evaluation index value, it is determined whether or not to adopt the arrangement image as a candidate image showing a candidate arrangement of the member. A program to execute.
