Description

Technical Field

[0001] The present invention relates to the field of data collection, and in particular to a design material collection method. Background Art

[0002] The traditional way of collecting design materials mainly relies on manual search by designers, such as entering keywords on search engines to find pictures, or screening one by one on some material websites. However, this method has many disadvantages. On the one hand, it is inefficient and requires designers to spend a lot of time screening useful materials from massive amounts of information. For example, when designing an environmental protection theme poster, it may take hours or even days to find pictures, icons and other materials that match the theme, style and quality requirements from many search engine results and material websites. On the other hand, accuracy is difficult to guarantee. Due to the limitations of keyword search, it is difficult to fully and accurately obtain materials that are highly matched with the design concept. There are often deviations between the materials and the design requirements, and they have to be screened and collected again.

[0003] Chinese patent application publication number: CN116861046A, discloses a material intelligent matching system for advertising design, which relates to the field of intelligent matching technology. First, the material storage end stores the basic material, and then the product information and design information are collected through the design information collection end, and the keywords are retrieved to obtain the adapted material. Then, the priority of the adapted material is calculated to obtain the keyword priority, and the proportion of the blank area and the standard proportion of the adapted element are extracted and compared. Then, the element complexity in the design screen is superimposed to obtain the screen complexity value, and compared with the preset complexity value, the element complexity value of the adapted element is obtained, and the comprehensive priority value of the adapted element is obtained. Then, the display terminal arranges and displays the adapted element according to the size of the comprehensive priority value, so that when relevant personnel retrieve the material, they can give priority to displaying the advertisement of the product being designed and the most suitable material matching the corresponding design screen.

[0004] However, there are still the following problems in the prior art: It takes a lot of time and energy to search and collect the materials needed for design in massive amounts of materials, and the search accuracy is not high. At the same time, when the collected materials are integrated with each other according to the design, there may be incompatibility issues between the materials. Summary of the invention

[0005] To this end, the present invention provides a design material collection method to overcome the problem in the prior art that it takes a lot of time and energy to search and collect the materials required for the design in massive materials, and the search accuracy is not high. At the same time, when the collected materials are integrated with each other according to the design, there may be problems of incompatibility between the materials.

[0006] To achieve the above object, the present invention provides a design material collection method, which comprises: Obtaining a design scheme to extract keywords corresponding to each part of the design scheme; Searching and collecting materials according to the subject words, and dividing the searched and collected materials into several material groups; Determine a material fit representation value based on the design material features of the material group to mark the material group; Calling the marked material groups corresponding to the various parts of the design solution, sorting the marked material groups according to the material matching representation values ​​corresponding to the marked material groups, and constructing a sorting sequence; Filtering and integrating the marked material groups according to the sorting sequence corresponding to each part of the design scheme, determining the overall material characteristics of the integrated preliminary material set, and analyzing the overall matching representation parameters of the preliminary material set; A preliminary material set is selected based on the overall matching characterization parameters, including: Determine the color matching degree of each material group in the preliminary material set, determine the matching material group within the group based on the color matching reference condition, match the matching material group within the group with the remaining marked material groups, so as to eliminate some marked material groups in the preliminary material set, and obtain a revised material set; Or, select the preliminary material set; Among them, the design material characteristics include the color matching degree of the sub-materials in the material group and the matching degree between the material group and the keyword, and the overall material characteristics include the overall coordination degree of the preliminary material set and the timeliness response degree between the preliminary material set and the keyword.

[0007] Further, the process of determining the material fit representation value based on the design material features of the material group includes: The ratio of the color matching degree of the material group to the color matching degree threshold is used as the first material matching feature; The ratio of the matching degree between the material group and the subject word to the matching degree threshold is used as the second material matching feature; Performing a weighted summation of the first material matching feature and the second material matching feature to obtain the material matching representation value; The matching degree between the material group and the keyword is determined based on each material in the material group.

[0008] Furthermore, marking the material group includes: If there is any material group whose corresponding material matching representation value is greater than or equal to the material matching representation threshold, the material group is marked.

[0009] Furthermore, the marked material groups are sorted according to the material matching representation values ​​corresponding to the marked material groups, including: The marked material groups are sorted in descending order according to the material matching representation value.

[0010] Furthermore, the process of selecting and integrating the preliminary material set according to the sorting sequence corresponding to each part of the design solution includes: Call the sorting sequence corresponding to each part; The marked material groups corresponding to the head end serial numbers in each of the sorted sequences are selected to form the preliminary material set for integration.

[0011] Furthermore, the process of analyzing the overall collocation characterization parameters of the preliminary material set includes: The ratio of the overall coordination degree of the preliminary material set to the overall coordination degree threshold is used as the first overall matching feature; The ratio of the timeliness relevance between the preliminary material set and the subject word to the timeliness relevance threshold is used as the second overall collocation feature; taking the sum of the first overall collocation feature and the second overall collocation feature as an overall collocation representation parameter of the preliminary material set; Among them, the overall coordination degree is determined based on the probability of occurrence of several material combinations in the preliminary material set in the finished design samples of the finished design sample library, and the timeliness response degree is determined based on the difference ratio of the shelf time of each material in the preliminary material set.

[0012] Further, a preliminary material set is selected according to the overall matching characterization parameter, including: If the overall matching characterization parameter is less than the overall matching characterization parameter threshold, the color matching degree of each material group in the preliminary material set is determined, the matching material group within the group is determined based on the color matching benchmark condition, and the matching material group within the group is matched with the remaining marked material groups to eliminate some marked material groups in the preliminary material set to obtain a revised material set; If the overall collocation characterization parameter is greater than or equal to the overall collocation characterization parameter threshold, the preliminary material set is selected.

[0013] Further, the color matching material group is determined based on the color matching reference condition, including: The set of marked material groups that meet the color matching benchmark conditions in the preliminary material set is used as the in-group matching material group; The color matching reference condition includes that the color matching degree of the marked material group is greater than or equal to a color matching degree threshold.

[0014] Further, matching the collocation material group within the group with the remaining marked material groups includes: Determine the color matching degree of the matching group within the group and the remaining marking material groups; If the color matching degree of the marked material group and each matching group within the group is less than a predetermined color matching degree threshold; Then the marked material group is removed.

[0015] Furthermore, the method further includes sending the preliminary material set or the revised material set to a user terminal.

[0016] Compared with the prior art, the present invention obtains a design scheme to extract keywords corresponding to each part of the design scheme; searches and collects materials based on the keywords, and divides the searched and collected materials into several material groups; determines a material fit representation value based on the design material characteristics of the material group to mark the material group; calls the marked material groups corresponding to each part of the design scheme, sorts each marked material group according to the material fit representation value corresponding to each marked material group, and constructs a sorting sequence; screens and integrates the marked material groups according to the sorting sequence corresponding to each part of the design scheme, determines the overall material characteristics of the integrated preliminary material set, and analyzes the overall matching representation parameters of the preliminary material set; selects the preliminary material set based on the overall matching representation parameters. The present invention can improve the adaptability of the material while ensuring the efficiency of material search and collection.

[0017] In particular, the present invention takes into account the color matching between the collected materials and the matching between the materials and the theme of the design scheme. In actual situations, in terms of the presentation effect of a design product, the colors of multiple materials should be relatively coordinated after fusion, so as to ensure the product's ornamental value. At the same time, it can display the content to be expressed by the design. The keywords can usually represent the key information that the design scheme wants to convey. Therefore, a high matching degree between the materials and the keywords of the design scheme can ensure that the theme of the design scheme is clear. Furthermore, the present invention determines the material fit characterization value through the color matching degree of the sub-materials in the material group and the matching degree between the material group and the keywords, so as to characterize the matching and coordination degree between each material and between each material and the keywords, and provide data support for the subsequent marking of the material group. The present invention can improve the adaptability of the material while ensuring the efficiency of material search and collection.

[0018] In particular, the present invention marks and sorts the material groups that have coordinated color matching and echo with the theme to determine the preliminary material set, analyzes the overall matching degree of the preliminary material set, and when the collected materials are integrated and applied, in addition to considering the matching and coordination degree of the materials within the material group, more attention is paid to the matching and coordination of the material set as a whole, so that the design scheme maintains consistency and integrity in content and style, and ensures the overall viewing experience. At the same time, the present invention considers the difference in the time when the materials are put on the shelves and introduces the timeliness response degree to reflect the timeliness and novelty of the materials, so that the design scheme can better adapt to the trend of the times and current needs, and improve the viewers' acceptance and recognition of the design scheme. Therefore, the present invention analyzes the overall matching characterization parameters through the overall coordination degree of the preliminary material set and the timeliness response degree between the preliminary material set and the theme, so as to characterize the overall effect of the determined preliminary material set, and provide data support for whether to adjust the selected material groups corresponding to the various parts of the design scheme in the future. The present invention can improve the adaptability of the material under the premise of ensuring the efficiency of material search and collection.

[0019] In particular, under the premise of the overall coordination and coherence of the determined preliminary material set and the consistency of the information conveyed in the time dimension, it is considered that the material groups with inharmonious colors in the preliminary material set will have an abrupt effect on the overall design, and the corresponding material groups are eliminated, and finally a revised material set is determined in which the overall design colors are matched with each other and echo each other in the time dimension.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] See also Figure 1 As shown, it is a schematic diagram of the steps of the design material collection method according to an embodiment of the present invention. The design material collection method according to the embodiment of the present invention includes: Step S1, obtaining a design scheme to extract keywords corresponding to each part of the design scheme; Step S2, searching and collecting materials according to the subject words, and dividing the searched and collected materials into several material groups; Step S3, determining a material fit representation value based on the design material features of the material group to mark the material group; Step S4, calling the marked material groups corresponding to the various parts of the design solution, sorting the marked material groups according to the material matching representation values ​​corresponding to the marked material groups, and constructing a sorting sequence; Step S5, screening and integrating the marked material groups according to the sorting sequence corresponding to each part of the design solution, determining the overall material characteristics of the integrated preliminary material set, and analyzing the overall matching representation parameters of the preliminary material set; Step S6, selecting a preliminary material set according to the overall matching characterization parameters, including: Determine the color matching degree of each material group in the preliminary material set, determine the matching material group within the group based on the color matching reference condition, match the matching material group within the group with the remaining marked material groups, so as to eliminate some marked material groups in the preliminary material set, and obtain a revised material set; Or, select the preliminary material set; Among them, the design material characteristics include the color matching degree of the sub-materials in the material group and the matching degree between the material group and the keyword, and the overall material characteristics include the overall coordination degree of the preliminary material set and the timeliness response degree between the preliminary material set and the keyword.

[0025] Specifically, the design plan is presented in text form, which can reflect the description of the design ideas of each part. There is no limitation on the method of determining the corresponding keywords of each part of the design plan. It only needs to be able to determine the corresponding keywords according to the content of each part of the design plan. In some possible implementations, corresponding subject words are identified in some design solutions by using text analysis software, such as Leximancer, relying on semantic analysis technology; In some possible implementations, the keywords of the corresponding design solution part are determined by using relevant plug-ins in office software, for example, keyword extraction in the text analysis function of Microsoft Word. Correspondingly, WPS also has similar plug-in functions, which will not be repeated here.

[0026] It can be understood that the materials are searched and collected according to the keywords corresponding to each part of the design plan, and the searched and collected materials are divided into several material groups, that is, one keyword corresponds to several material groups, which will not be elaborated here.

[0027] Specifically, the process of determining the material fit representation value based on the design material features of the material group includes: The ratio of the color matching degree of the material group to the color matching degree threshold is used as the first material matching feature; The ratio of the matching degree between the material group and the subject word to the matching degree threshold is used as the second material matching feature; Performing a weighted summation of the first material matching feature and the second material matching feature to obtain the material matching representation value; The matching degree between the material group and the keyword is determined based on each material in the material group.

[0028] In implementation, the matching degree between a material group and a keyword is the average matching degree between each material in the material group and the keyword.

[0029] There is no limitation on the method of determining the matching degree between the material and the keyword. It can be understood that the material is an image and the keyword is a text. In implementation, the CLIP cross-modal learning model can be used to map the image and text into the same semantic vector space, and the feature vectors of the image and text are extracted respectively through the image encoder and the text encoder, and then the cosine similarity between the two is calculated, and the cosine similarity is determined as the matching degree.

[0030] In implementation, there is no limitation on the method of calculating the color matching degree. The color features in the image can be extracted based on image processing tools such as OpenCV, and the mean Euclidean distance of each color feature in the two images in the RGB space is calculated respectively. The reciprocal of the mean Euclidean distance is determined as the color matching degree. The color matching degree of the material group is the mean of the color matching degrees between the materials in the material group.

[0031] In implementation, when performing weighted summation, the weight of the first material matching feature is set to 0.45, and the weight of the second material matching feature is set to 0.55; In this embodiment, the purpose of setting the color matching threshold of the material group and the matching threshold between the material group and the keyword is to characterize the situation in which the materials in the material group have a high degree of mutual response and fit in the overall effect presentation. The color matching threshold and the matching threshold are pre-set, wherein a number of design product samples are obtained in advance, and the color matching mean and matching mean of each material used in the design product samples are determined. The color matching threshold is set to the product of the color matching mean and the offset coefficient, and the matching threshold is set to the product of the matching mean and the offset coefficient. The offset coefficient is selected within the interval [0.75, 0.95].

[0032] Specifically, the present invention considers the color matching between the collected materials and the matching between the materials and the theme of the design scheme. In actual situations, in terms of the presentation effect of a design product, the colors of multiple materials should be relatively coordinated after fusion, so as to ensure the ornamental value of the product and at the same time, to show the content to be expressed by the design. The keywords can usually represent the key information that the design scheme wants to convey. Therefore, the high matching degree between the materials and the keywords of the design scheme can ensure that the theme of the design scheme is clear. For example, when each material is closely centered around a keyword, viewers can quickly understand the core content and intent of the design and avoid misunderstanding or ambiguity. When the material and the keyword have a low match and low relevance, the theme of the design will be unclear and viewers will have difficulty grasping the key points of the design. Therefore, the present invention determines the material fit representation value through the color matching degree of the material group and the matching degree between the material group and the subject word, so as to characterize the matching and coordination degree between each material and between each material and the subject word, and provide data support for the subsequent marking of the material group. The present invention can improve the adaptability of the material while ensuring the efficiency of material search and collection.

[0033] Specifically, see Figure 2 As shown, it is a logical decision diagram for marking a material group according to an embodiment of the present invention. Marking the material group includes: If there is any material group whose corresponding material matching representation value is greater than or equal to the material matching representation threshold, the material group is marked.

[0034] Specifically, in implementation, the material fit representation threshold is selected within the interval [1.05, 1.15].

[0035] Specifically, sorting the marked material groups according to the material matching representation values ​​corresponding to the marked material groups includes: The marked material groups are sorted in descending order according to the material matching representation value.

[0036] It is understandable that one-to-one corresponding serial numbers can be set for the marked material groups, and then the serial numbers can be sorted to obtain a sorted sequence, and the marked material groups corresponding to the serial numbers in the sorted sequence can be determined.

[0037] Specifically, the process of selecting and integrating the preliminary material set according to the sorting sequence corresponding to each part of the design solution includes: Call the sorting sequence corresponding to each part; The marked material groups corresponding to the head end serial numbers in each of the sorted sequences are selected to form the preliminary material set for integration.

[0038] Specifically, the process of analyzing the overall collocation characterization parameters of the preliminary material set includes: The ratio of the overall coordination degree of the preliminary material set to the overall coordination degree threshold is used as the first overall matching feature; The ratio of the timeliness relevance between the preliminary material set and the subject word to the timeliness relevance threshold is used as the second overall collocation feature; taking the sum of the first overall collocation feature and the second overall collocation feature as an overall collocation representation parameter of the preliminary material set; Among them, the overall coordination degree is determined based on the probability of occurrence of several material combinations in the preliminary material set in the finished design samples of the finished design sample library, and the timeliness response degree is determined based on the difference ratio of the shelf time of each material in the preliminary material set.

[0039] It is understandable that the preliminary material set may include several material groups, which in turn may include several materials, thereby forming several material combinations consisting of two materials.

[0040] It is understandable that a finished product design sample library storing a number of finished product design samples may be pre-built. The finished design sample is the finished product of the design. It can be understood that the finished design sample adopts several materials in the design process. Then, the probability of the corresponding material combination in a single finished design sample is considered. The higher the probability, the better the corresponding coordination between the materials in the material combination and the higher the adoption rate. Then, the average probability of the occurrence of several material combinations in the preliminary material set is taken as the overall coordination degree to characterize the overall coordination of the preliminary material set.

[0041] Specifically, the difference ratio between the shelf time of each material in the preliminary material set is solved, and the mean of the difference ratio is determined as the timeliness responsiveness. It can be understood that the difference ratio of two values ​​is the ratio of the difference between the two values ​​to the mean of the two values.

[0042] Specifically, the overall coordination threshold and the timeliness response threshold are predetermined, where: Determine in advance one by one the overall coordination between the materials used in the finished design samples in the finished design sample library, calculate the average of the overall coordination corresponding to each finished design sample, and determine the average of the overall coordination as the overall coordination threshold; Determine in advance one by one the timeliness response between the materials used in the finished design samples in the finished design sample library, calculate the average timeliness response corresponding to each finished design sample, and determine the average timeliness response as the timeliness response threshold.

[0043] Specifically, the present invention marks and sorts the material groups with coordinated colors and echoing the theme to determine the preliminary material set, analyzes the overall matching degree of the preliminary material set, and when integrating and applying the collected materials, in addition to considering the matching and coordination degree of the materials within the material group, pays more attention to the matching and coordination of the material set as a whole to ensure the overall ornamental value, so as to enable the design scheme to maintain consistency and integrity in content and style. For example, the material groups corresponding to each part are unfolded together around the corresponding theme, echoing each other to form an organic whole, bringing smooth visual and psychological experience to the viewer; on the contrary, the material groups that cannot echo each other will destroy the coherence of the design, making the design appear It is loose and lacks logic. At the same time, the present invention takes into account the differences in the time of material listing and introduces timeliness response to reflect the timeliness and novelty of the materials, so that the design scheme can better adapt to the trend of the times and current needs, and improve the viewers' acceptance and recognition of the design scheme. Therefore, the present invention analyzes the overall matching characterization parameters through the overall coordination of the preliminary material set and the timeliness response between the preliminary material set and the theme to characterize the overall effect of the determined preliminary material set, so as to provide data support for whether to adjust the selected material groups corresponding to each part of the design scheme in the future. The present invention can improve the adaptability of the material under the premise of ensuring the efficiency of material search and collection.

[0044] Specifically, see Figure 3 As shown, it is a logical decision diagram for selecting a preliminary material set according to an embodiment of the present invention. The preliminary material set is selected according to the overall matching characterization parameter, including: If the overall matching characterization parameter is less than the overall matching characterization parameter threshold, the color matching degree of each material group in the preliminary material set is determined, the matching material group within the group is determined based on the color matching benchmark condition, and the matching material group within the group is matched with the remaining marked material groups to eliminate some marked material groups in the preliminary material set to obtain a revised material set; If the overall collocation characterization parameter is greater than or equal to the overall collocation characterization parameter threshold, the preliminary material set is selected.

[0045] Specifically, the threshold of the overall collocation characterization parameter is selected in the interval [1.85, 1.95].

[0046] Specifically, the color matching material group is determined based on the color matching benchmark conditions, including: The set of marked material groups that meet the color matching benchmark conditions in the preliminary material set is used as the in-group matching material group; The color matching reference condition includes that the color matching degree of the marked material group is greater than or equal to a color matching degree threshold.

[0047] Specifically, see Figure 4 As shown, it is a logical decision diagram for removing the marked material group according to an embodiment of the present invention, matching the collocation material group in the group with the remaining marked material groups, including: Determine the color matching degree of the matching group within the group and the remaining marking material groups; If the color matching degree of the marked material group and each matching group within the group is less than a predetermined color matching degree threshold; Then the marked material group is removed.

[0048] Specifically, the color matching degree between each material in the intra-group matching group and each material in the marked material group is calculated respectively, the color matching mean is solved, and then the color matching degree between the intra-group matching group and the marked material group is obtained, which will not be repeated here.

[0049] Specifically, under the premise of the overall coordination and coherence of the determined preliminary material set and the consistency of the information conveyed in the time dimension, it is considered that the material groups with inharmonious colors in the preliminary material set will have an abrupt effect on the overall design, and the corresponding material groups are eliminated, and finally a revised material set is determined in which the overall design colors match each other and echo each other in the time dimension.

[0050] Specifically, it also includes sending the preliminary material set or the revised material set to the user terminal, so that the user terminal can select materials in the preliminary material set to improve the user experience.

[0051] If the design material collection method of the present invention is implemented in the form of a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art or all or part of the technical solution can be embodied in the form of a software product. The computer software product is stored in a storage medium, including a number of instructions for enabling a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present invention, and the aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), disk or optical disk, etc. Various media that can store program codes.

[0052] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
