Generally, the shoe logo design device based on the related elements can be a computer device such as a computer, a mobile phone and a tablet.
The following description will be given by taking the color matching design equipment of the sneaker logo as an example of a main body for executing the shoe body logo design method based on the associated elements. Referring to fig. 1, the method for designing a shoe logo based on related elements specifically comprises the following steps:
s110, inputting a target image, detecting a main element graph of the target image, identifying color information of the main element graph, and constructing rendering display options of the main element graph and the color information.
When the shoe body logo is designed, a rendering display option is constructed by inputting a target image and based on a main element graph and corresponding color information provided by the target image. Then, a three-dimensional shoe body model is introduced to design relevant parameters of various parts (such as a logo, a vamp, a shoelace, a tongue, a midsole and an outsole) of the shoe body on the basic shoe body structure provided by the three-dimensional shoe body model. The method and the device mainly aim at the color matching of the shoe body logo and the logo associated element graph, identified color information is rendered and displayed on the basic outline graph displayed at the position of the shoe body three-dimensional model logo, and the main element graph is rendered in the associated element rendering area around the shoe body logo, so that the color matching and the associated element design of the shoe body logo are realized. Before that, a three-dimensional model of the shoe body is constructed in advance according to the shoe body with logo design required, so that various types of design results of the shoe body can be displayed visually, and the shoe body design effect is optimized. The method for constructing the three-dimensional model of the shoe body has a plurality of modes, and the specific construction mode is not fixedly limited in the embodiment of the application, so that the details are not repeated herein.
For example, in an actual design scene, when a user sees a favorite graphic element (e.g., a cartoon figure, a character or a building logo, an object figure, etc.), the image can be defined as a target image by shooting or downloading an image containing the corresponding graphic element. And then, detecting and identifying based on the target image, and acquiring the main element graph and the corresponding color information in the target image. So as to render and display the main element graph and the color information thereof on the three-dimensional model of the shoe body.
Inputting the target image into a pre-constructed target detection model, and positioning the main element graph of the target image based on the target detection model. Before that, an object detection model needs to be constructed in advance to detect and identify the main element graph of the object image. In order to train the target detection model of the main element graph, it is necessary to collect various types of image information (such as various cartoon graphs, characters or building signs, object graphs, and the like) as a training data set, and then manually mark out a rectangular frame of the main element graph from the image information one by one as marking data. And further designing a neural network structure and a loss function of the target detection model of the main element graph, and training network parameters of the target detection model of the main element graph by using the labeling data. After model training is completed, the model structure and parameters are saved for subsequent target detection. The method can be used for detecting the main element graph by constructing a target detection model of the main element graph in advance. According to actual needs, a target detection model such as YOLOv5 can be selected as the target detection model, and the specific detection model is not fixedly limited in the embodiments of the present application and is not described herein any more.
And deploying the trained target detection model on the exclusive customization equipment of the sneaker logo in the embodiment of the application. The target image input by the user is input into the target detection model, and the detection frame of the main element graph in the target image can be output through model calculation and processing, so that the detection of the main element graph is completed. For example, when a user sees a graphic mark, the user takes an image of the graphic mark as a target image, inputs the target image into a target detection model, and performs model training based on various types of graphics in advance by the target detection model, so that a graphic mark part in the target image can be detected as a main element graphic, and the main element graphic detection of the target image is completed.
Further, based on the detected main element graph, when the color information of the main element graph is collected, a binary image is generated by performing binary processing on the main element graph, and the color information of the main element graph is determined based on the RGB value of the binary image. By utilizing the color information provided in the main element graph, the color matching setting of the logo of the shoe body three-dimensional model currently being designed can be carried out, the color matching design of the shoe body logo can be ensured to be matched with the associated graph elements, the rendering and displaying effects of the shoe body logo and the associated graph elements are mutually adaptive, and large color matching difference can not occur. Therefore, the setting efficiency of logo color matching is improved, the color matching design effect of the logo is optimized, and meanwhile, the flexibility and the interestingness of the shoe logo color matching setting are improved.
When the color information of the main element graph is obtained, the color information of the main element graph can be determined based on the image characteristics by identifying the image characteristics of the main element graph. For example, the subject element figure is binarized to generate a binarized image, and the RGB values of the binarized image are determined. Because different RGB values represent different colors, the RGB color table is inquired according to the RGB values, and the color information of the current main element graph can be determined. There are many ways to perform color recognition based on images, and the specific detection recognition way is not fixedly limited in the embodiments of the present application, which is not described herein repeatedly.
Based on the determined main element graph and the color information, the embodiment of the application constructs a rendering display option based on the color information and the main element graph, so that a user can select rendering. It can be understood that by constructing the rendering and displaying option containing the color information and the main element graph, a subsequent user can directly select the rendering and displaying option to perform rendering and displaying of the logo rendering area and the associated element rendering area, so that logo rendering and displaying efficiency can be further improved, and logo design experience of the user is optimized.
120. And importing a shoe body three-dimensional model, and positioning a logo rendering area and a related element rendering area which are marked in advance on the shoe body three-dimensional model, wherein the related element rendering area is a rectangular frame which is defined in advance on the surface of the shoe body three-dimensional model, and the logo rendering area is overlapped with the logo outline of the shoe body three-dimensional model.
Furthermore, based on the determined color information and the rendering display options constructed by the main element graphics, when the logo of the sneakers is designed, the position of the logo is positioned in the three-dimensional model of the shoe body by inputting the three-dimensional model of the shoe body, and the corresponding logo rendering area is determined. And determining a related element rendering area so as to render and display the main element graph. When the user selects the rendering display option through interactive operation, the color information can be rendered and displayed in the logo rendering area, and the main element graph is rendered and displayed in the logo rendering area.
Before that, the three-dimensional model of the shoe body marks the rendering display area of each shoe body component on the three-dimensional model of the shoe body in advance so as to facilitate the color matching design of each component. Therefore, when a shoe logo is selected for design through user interactive operation, a logo rendering area marked in advance on the shoe three-dimensional model can be positioned. And at the moment, only displaying the outline of the logo in the logo rendering area, and then rendering and displaying the determined color information to the logo rendering area so as to finish the logo color matching design of the football shoe.
On the other hand, in order to improve the interest of logo design, associated marks or graphic element information are embodied on the shoe logo. According to the embodiment of the application, a related element rendering area is defined around the logo rendering area so as to be used for rendering and displaying the main element graph. For example, graphic elements such as personal trademarks, name abbreviations and the like of speakers are displayed around the football shoe logo, so that the interest of logo design is improved, the logo design effect is optimized, and the logo design requirements of different scenes are met. Generally, the associated element rendering area is delimited as a rectangular box of fixed size. The user can also adjust the shape and size of the associated element rendering area according to the actual rendering requirements. And based on the preset logo rendering area and the preset associated element rendering area, after the rendering display options of the main element graph and the color information are established, rendering display can be carried out on the areas.
S130, in response to the selection operation of the user on the rendering display option, rendering and displaying the main element graph to the associated element rendering area, and rendering and displaying the color information to the logo rendering area.
Then, when shoe body design is carried out based on the shoe body three-dimensional model, a user can render and display the main element graph to the associated element rendering area and render and display color information to the logo rendering area by clicking the rendering and displaying option, and therefore the whole shoe body logo design process is completed. Through the process, the display effect of the matching of the shoe body logo and the associated elements is displayed on the shoe body three-dimensional model, so that the shoe body logo design effect is optimized.
Optionally, according to the actual rendering display requirement, the user may adjust the display effect of the main element graph through a related touch operation. The shoe body logo design equipment based on the related elements rotates the corresponding angle value of the main element graph by responding to the touch operation of a user on the main element graph. For example, the user drags the main element graph displayed on the shoe body three-dimensional model to rotate by a corresponding angle through human-computer interaction so as to achieve the display effect according with the expectation of the user. In addition, according to actual needs, the user can also adjust the display position and the display size of the main element graph through human-computer interaction operation, so that the overall display effect of the main element graph is matched with the logo, and the display effect is optimized.
Optionally, the shoe body logo designing device based on the related elements further includes, after importing the shoe body three-dimensional model: inquiring a pre-constructed mapping relation according to the type of the shoe body to which the three-dimensional shoe body model belongs, and determining corresponding logo material information as target material information, wherein the mapping relation binds different logo material information with the corresponding shoe body type in advance, the logo material information comprises a digital map of corresponding fabric, and the digital map is obtained by carrying out digital scanning processing on the basis of the corresponding fabric; correspondingly, before rendering and displaying the color information to the logo rendering area, the method further comprises the following steps: and rendering and displaying the target material information to the logo rendering area.
And on the basis of the shoe body three-dimensional model, logo material design is also carried out for optimizing logo design effect. When logo material design is carried out, material information of a current shoe body three-dimensional model is determined at first. Before the above, the shoe body logo design equipment based on the related elements binds different logo material information with corresponding shoe body types in advance, and constructs mapping information, so that when target material information of shoe body logos is selected, the corresponding logo material information is selected as the target material information according to the shoe body types to which the current shoe body three-dimensional models belong. For example, a designer binds logo material information of the leather fabric with the shoe type of the sneakers according to design requirements to construct a mapping relation. When the shoe body is designed based on the shoe body three-dimensional model, if the shoe body type of the introduced shoe body three-dimensional model is a football shoe, the target material information can be determined to be the leather fabric through the mapping relation. According to actual design needs, different logo material information such as leather fabrics, impression fabrics, chamois fabrics and knitted fabrics is bound to different shoe body types such as leather shoes, cloth shoes and running shoes in an adaptive mode, corresponding mapping relations can be built, and target material information determination during subsequent logo design is facilitated.

In one embodiment, if the color information is multiple and multiple sub-areas are preset in the logo rendering area, color matching design needs to be performed in the sub-areas. Wherein, the color matching partition rendering process comprises the following steps:
determining a plurality of preset sub-areas of the logo rendering area under the condition that the number of the color information is multiple;
and rendering and displaying each color information to the corresponding sub-area.
It can be understood that in order to optimize the color matching design effect of the logo, the situation that the color matching display of the logo is monotonous due to the single logo color matching design is avoided, the color matching rendering display is carried out by dividing different sub-areas and using different color information, and the personalized setting effect of the logo color matching design can be improved. The sub-regions can be divided adaptively according to a pre-designed graphic outline in the logo, and according to actual design requirements, a user can set each sub-region in the logo rendering display region in a personalized manner.
Illustratively, when the regional rendering display is carried out, color matching rendering options of the color information are constructed; responding to the click operation of a user on one sub-region, determining a corresponding target sub-region, and displaying each color matching rendering option; and rendering and displaying the corresponding color information to the target sub-area according to the color matching rendering option selected by the user.
Specifically, when the regional color matching rendering display of the logo rendering display region is performed, a corresponding color matching rendering option is firstly constructed based on each color information, so that the color matching rendering display of each sub-region can be selected. It can be understood that, in order to improve the flexibility and the diversity of the color matching setting, the embodiment of the application constructs the color matching rendering option through each color information, so as to perform the color matching setting of each preset sub-area of the three-dimensional model logo of the shoe body according to the color matching rendering option subsequently. And the user clicks the corresponding sub-areas one by one to carry out interactive operation, and selects the pre-constructed color matching rendering option, so that the corresponding color information can be rendered and displayed to the sub-area selected by the user. And by analogy, completing the color matching design of each sub-area.
In addition, when the regional rendering display is carried out, master color matching information and slave color matching information can be determined from each color information, and a master region and a slave region can be determined from each sub-region; and rendering and displaying the master color matching information to the master area, and rendering and displaying the slave color matching information to the slave area.
Specifically, in the logo color matching design process, part of a large-area needs to be emphasized in color matching design, and main color information of a target image needs to be displayed in the area. And the other areas with smaller areas can be used for adaptively making relevant color matching design. Therefore, according to the actual design requirement of a user, each sub-area of the logo rendering display area can be divided into a master area and a slave area so as to adaptively render and display the master color matching information and the slave color matching information on the target image.
Based on this, when the color information of the main element graph of the target image is identified, the main color matching information and the auxiliary color matching information are further determined from the plurality of identified color information, so that the subsequent color matching rendering display of different sub-areas in the logo rendering display area is facilitated.
When the master coloring information and the slave coloring information of the color information are determined, the area ratio of each piece of color information in the target image main element graph is determined, the color information with the largest area ratio is selected as the master coloring information, and the rest pieces of color information are selected as the slave coloring information. The area ratio of different RGB values (namely different colors) in the target image main element graph is determined, the area with the largest area ratio is taken as the main color matching information, and the rest color matching information is correspondingly set as the auxiliary color matching information.
And then, rendering and displaying the master color matching information to the corresponding master region, and rendering and displaying the slave color matching information to the slave region. Since there may be a plurality of slave color matching information and slave regions, when rendering display from the regions is performed, rendering display from the color matching information is performed using random selection. Or by constructing rendering display options from the color matching information for the user to select for rendering display from the region. Therefore, the flexibility and diversity of color matching setting are improved, and the color matching design effect of the sneaker logo is optimized.
