Description

[Technical Field]

[0001] The present invention relates to a visual proposal system for interior decoration plans that allows a client's requests for interior decorations such as curtains to be visually reproduced in a natural way. [Background technology]

[0002] Replacing or replacing curtains is one of the so-called interior makeovers of a residential room. In many cases, the client looks at small pieces of sample fabric, selects the one they like, decides on the decorative specifications, and then leaves most of the work to the contractor, waiting for completion. However, when it comes to color, even if a good impression is made from small pieces of sample fabric, when the curtain is assembled as a whole, the color tone is not necessarily the desired one, it does not harmonize with the colors of the surrounding furniture, walls, floors, etc., and furthermore, because it is a curtain, the shadow pattern created by the pleats is not fully utilized, and so it often falls short of expectations.

[0003] For this reason, simulation systems are available that allow users to virtually check the interior decoration specifications, including curtains, when selecting them. However, most of these are merely professional tools to support the creative work of architects and designers, and are limited to the use of CG techniques in which color patterns are pasted onto pre-prepared images or designed simulated interior spaces, and often do not necessarily match the appearance of the actual space in which the client lives. Of course, there are also full-scale simulation tools available that allow users to insert desired decorative materials into photos of the actual interior of the room to be decorated or renovated, but there is still room for improvement in terms of usability (Prior Art Documents 1 and 2). In particular, when trying to insert pre-recorded material into such indoor photographs at an appropriate position, the user had to use a computer to accurately correct the position and distortion caused by shooting from an oblique angle each time. Of course, in recent years, there have been proposals for performing fitting operations via touch panels on high-performance smartphones and tablet devices, but these are not necessarily easy to use (Prior Art Document 3). In particular, curtains have folds that are specific to curtains, and the presence of these folds is indicated by shading and color shading. When an image of a curtain material is composited onto a photograph taken with the window where the curtain is attached at an angle, as in Prior Art Documents 1, 2, and 3, an image taken from the front is forcibly transformed and pasted onto an image taken from an oblique angle, resulting in an image in which the folds of the curtain are unnaturally oriented at an angle, resulting in a somewhat unnatural appearance.

[0004] On the other hand, simulation tools aimed at general customers, not just professionals such as interior designers, have also been proposed (Prior Art Document 4). However, these tools do not use specialized modifiers like those used by interior designers, but instead input commonly used onomatopoeia such as onomatopoeic words and mimetic words, suggesting decorative elements and displaying image images. However, such methods are not necessarily able to adequately express subtle nuances of decorative preferences, and whether or not they can come close to meeting the user's needs depends on the number of words used to express them and their affinity with onomatopoeic expressions, making it impossible to propose coordination for complex or difficult-to-categorize subtle categories that cannot be adequately expressed with such words.

[0005] In addition, when it comes to color elements, the electronic data for each color is reproduced using RGB representation for extremely microscopic analysis, and this is displayed on a screen with a certain number of pixels, so it does not accurately reflect the situation as seen with the naked eye in an actual indoor living space. In other words, when viewed with the naked eye, the color appears more ambiguous or blurred than the color on the display, creating a visually familiar impression. However, the display does not reproduce this visually familiar impression, and in an attempt to reproduce it faithfully, the presence of the pattern may become excessively strong, or the pattern itself may become unrecognizable, which may result in the client feeling uncomfortable after the actual product is installed.

[0022] The present invention is preferably implemented in the following examples, and various technical modifications and additions are possible within the scope of this technical concept. The visual proposal system S for interior decoration plans of the present invention is recorded and executed in a recording device ST of a server M connected to a network N, and is provided as a program SW via the network N, which outputs and proposes suitable decoration specifications in response to input of a client U's interior decoration construction requests. The program SW in this visual proposal system S for interior decoration plans includes a target interior information providing step s1, a decoration preference input step s2, a decorative element presentation and selection step s3, and a visual display proposal step s4.

[0023] The target room information providing step s1 provides an image of the target room that the client U requests to be constructed using a digital camera function of the information terminal T, or a pre-recorded CG image or a photograph of the room, etc., as binary data. Image of the target room p0 is input to the recording device ST on the system and saved. Of course, a simple method of temporarily saving it in a memory managed by an application running on the information terminal T on the client U side may also be used. In the next decoration preference input step s2, the client U inputs information (decoration preference information i1) for determining decoration preferences that express the client's preferences and desires regarding the decoration elements presented on the screen. In the next decorative element presentation and selection step s3, decorative elements extracted in consideration of the decorative preference information i1 input by the client U are presented, and the client U selects and specifies one from among them according to his or her preference. The next and final step, the visual display suggestion step s4, is to present the decorative element data Ie selected by the client U in the decorative element presentation and selection step s3 as follows: Image of the target room p0 and then proposes to display it as a composite image P that is visible to the client U.

[0024] This will be explained in more detail below. First, the visual proposal system S for interior decoration plans of the present invention is, so to speak, actively operated by a client U via a network, for example the Internet web, and proposes decorative specifications suitable for the client U's individual interior decoration as a composite image P. First, the required input items in the target room information provision step s1 are the target room conditions for which the client U requests construction. Image of the target room It is input into the system as binary data p0. When inputting data into the system, several options are available as shown in Figure 3-1(1). A typical option is, for example, taking a photo with a smartphone or digital camera and mapping the image as shown in Figure 3-1(2). Image of the target room p0 is input as binary data. Another option is to use this system for interiors that do not include everyday necessities, such as newly built buildings or buildings that people are planning to move into. For example, you can use interior photo data prepared in advance by the house builder who designed the building, or CG interior image data. Image of the target room There is something to input as p0.

[0025] After completing the binary data input operation into this system, correction work is performed to create a composite image P that faithfully reproduces the decorative element image data by embedding and synthesizing them in the final visual display proposal step s4, as shown in Figure 3-2. The specific correction process involves adjusting the image of the decorative element fixed on the screen as shown in Figure 4-1, using the guide marker (the thick solid line in the figure) that predicts the fitting position as the target. Image of the target room By moving p0 appropriately or changing the scale of the image, Image of the target room The position where the desired decorative element data Ie should be inserted (shown by the thick dashed line in the figure) is to be matched with the position where the desired decorative element data Ie should be inserted (shown by the thick dashed line in the figure). This allows the system to determine the position and size at which the desired decorative element data Ie should be inserted and combined. In this embodiment, as shown in Figure 4-1, a curtain is used as a decorative element, and the procedure in this case will be explained. First, an image is fixedly displayed on the top layer of the screen where input is performed, with a guide marker (shown by the thick solid line in the figure) that resembles a curtain rail for hanging curtains, for example, located near the center. Then, Image of the target room p0 is placed in a state where it can be moved and scaled. The client U then moves the position and changes the scale to match the position and size of the curtain rail installation position (thick dashed line in the figure) of the target room image p0 arranged on the bottom layer with the curtain rail-shaped guide marker (thick solid line in the figure) displayed on the top layer. In other words, in the area drawn by this system, Image of the target room Its distinctive feature is that by combining the position and size of p0, complicated operations are no longer necessary.

[0026] In such indoor information providing step s1, the primary information is an actual image of the room, that is, a target indoor image. In contrast, when using pre-recorded CG images, there are insufficient judgment elements (hints) to make suggestions like those for real images, so it is necessary to appropriately add supplemental image content information i1', which is part of the decorative preference information i1, which is a detailed judgment element. Specifically, as shown in Figure 4-2, to operate the system more accurately, supplemental image content information i1' such as room type, furniture status, window shape, floor color, wall color, and curtain rail status is input.

[0027] In order for the client U to actively specify his / her decorative preferences, the system can understand the decorative preferences by inputting options based on design terms that indicate design concepts prepared in advance by the system, or by inputting keywords or phrases that represent the concept of the decorative design. (Color specification) First, as shown in Figure 5-1, various information about color, which is a key element of decorative preferences, is entered into the system. Specifically, the preferred color, hue, saturation, brightness, etc., can be specified using a color chart, color representation using various values ​​such as RGB values ​​or CMYK values, or color designation numbers from paint manufacturers, etc. In addition, it is also possible to specify a color extracted from an image of an object or other object contained in an actual image. It is also possible to select a color from a sample of decorative elements.

[0028] (Taste selection) Furthermore, in addition to selecting the client U's color preferences, the client U's requests for so-called taste preferences can also be accommodated. For example, as shown in Figure 5-1, for tastes that have a fairly vague impression, such as "natural taste," "simple taste," "classic style," and "Scandinavian style," a number of sample images can be displayed to allow the client to grasp the image of the taste before making a selection. If the client U desires an interior design that combines multiple tastes, multiple tastes may be selected as appropriate.

[0029] In addition, although not shown in the figure, information that cannot be fully grasped even with an actual image to be added to the decorative preference information i1 for discrimination (environmental attribute information i2) is, for example, information such as the direction in which the window to hang the curtains is installed, for example, whether it faces east, west, north, or south. By inputting this information, it is possible to expect suggestions that take into account the influence of sunlight, etc.

[0030] Furthermore, the external environment outside the window can also be input as environmental attribute information i2. For example, reference information may include whether a natural landscape can be seen outside the window, whether the house is close to a neighboring house, etc. Furthermore, color information of the exterior walls of a neighboring house that is close may also be environmental attribute information i2. Furthermore, family structure and other factors can also be environmental attribute information i2. In other words, if there are a relatively large number of elderly people, it may be preferable to select a more subdued tone, so to speak, even within the desired color palette. In making such an estimation, various environmental attribute information i2 can be taken into consideration to select and propose appropriate decorative elements. Furthermore, if it is anticipated to some extent that the interior space will be repurposed in the future, it will be possible to select decorative specifications that will not look out of place even after the repurposing.

[0031] Furthermore, if the client U wishes to make further changes to the current state of the room, the client U can input those requests. For example, if the client U plans to make changes to the interior furniture or to its color, or if the color of the furniture currently installed does not necessarily match the client's preference, the client U can input the desired changes as environmental attribute information i2. The decoration preference information i1, image content supplementary information i1', and environmental attribute information i2 obtained in the target interior information provision step s1 and decoration preference input step s2 thus become basic and important information for determining the appropriate decoration specifications in the future.

[0032] After the client U inputs the decoration preference information i1, environmental attribute information i2, etc., the server M connected to the network N determines the client U's preferences based on the obtained decoration preference information i1, environmental attribute information i2, etc., taking into account known color psychology, etc. At this time, the system can also estimate the client U's preferences based on fragmentary information such as decoration preference, based on statistical rules of thumb.

[0033] In the subsequent decorative element presentation and selection step s3, candidate color elements are proposed. Specifically, samples that are pre-recorded in the recording device of the server M and that are thought to match the various requests entered by the client U in terms of function, color, and pattern are appropriately proposed. As shown in Figure 6, this decorative element proposal basically shows a color chart based on the decorative preference information i1 and environmental attribute information i2 input by the client U himself, and actual images of the decorative elements recorded in advance in the recording device of the server M. In addition to these, in addition to proposing decorative elements extracted from the information input by the client U, it is also possible to present other coordinations based on the interior designer's experience that are not known to the client U, for example, that have the same interior design concept but use different colors than the client U desires. These decorative element proposals may be presented as multiple samples simultaneously on the screen, or as a slide display, where the screen changes for each sample in turn. Presenting several candidates simultaneously is preferable because it allows the client U to compare them. Slide displays are also preferable because they are displayed large on the screen, reducing the sense of incongruity between the proposed content and the actual construction projection.

[0034] As shown in Figure 6, the client U clicks on a sample that matches their taste based on the suggestions for decorative elements. The samples are not particularly ranked when clicking, and one or more samples may be selected, or the client U may rank the samples and sequentially indicate their preference for a design that matches their taste.

[0035] After obtaining the client U's selection of decorative elements (such as curtains), the next step, visual display proposal step s4, presents an image that meets the client's request. Since the position for fitting the decorative element data Ie was specified in advance in target room information provision step s1, the image is automatically fitted in the appropriate position, for example, to a window in a room that has been previously input in line with the guide marker, so that the image appears as if it were a curtain. As a result, a composite image P is presented that has undergone sensitivity correction processing, making it appear as if the desired curtains have been fitted in the target room of the client U, as shown in Figure 7.

[0036] The decorative elements proposed at this time are recorded in the recording device of server M as detailed image data and vector data using various color expression methods, including RGB expression, with colors, patterns, and designs tiled based on a small piece of curtain fabric called a sample, for example. If such tiled image data is resized and fitted to the actual image captured by the client U, the image of the decorative element may differ significantly from how it would appear in real life when viewed with the naked eye. For this reason, the image is displayed with color correction performed, assuming that it would appear as if viewed with the naked eye as a correction factor. For example, curtains are woven with warp and weft threads to express patterns and color gradations, but if the color of only one of the warp or weft threads is reproduced, it is not possible to expose only one of the threads on the surface; the other thread will inevitably appear on the surface in order to form the fabric. When an undesired thread color appears on the surface due to structural requirements, it is not easy to determine using normal image processing whether this color should be considered an artificial pattern element or, from a structural design perspective, simply noise. For this reason, in this system, in the case of curtains, a sensitivity correction process is performed to make the image appear more natural when viewed from a certain distance, rather than a microscopic view of the fabric, and each decorative element data Ie is then inserted and synthesized into the original target room information p0.

[0037] This series of steps is the basic approach of the present invention, but a consulting step sC can be provided within each step so that the client U can receive an automatic answer or pseudo-face-to-face advice from an interior design expert. In this consulting step sC, the client U, who has viewed the composite image P displayed in the final visual display proposal step, can receive advice, either automatically or through web communication with a professional interior designer, regarding fine-tuning the color or the cost and time required for construction. As will be described later, by saving the composite image P, it is also possible to start only the consulting step sC at a later date at a time that is convenient for the client. In this case, it is also acceptable to display a screen for requesting a consultation appointment on the web, for example. [Example]

[0038] As a specific example of such a system, the flow for determining a curtain decoration plan will be described below with reference to the accompanying drawings. Note that this example minimizes the number of input items required to improve usability for the client U, and is simpler than the previously described embodiments. I. Guidance display The guidance display is displayed as a web page that guides users to the system, as shown in Figure 3-1(1), for example, in the case of a system that runs on the web. For this reason, it is preferable to include frequently used keywords such as "curtains," "interior," "plan," and "windows," as well as images, so that clients U who search for and access this system can easily find it (Figure 3-1).

[0039] II. Presentation of target room information from the client U (target room information provision step s1) i) Image of the target room Determination of p0 First, in Figure 3-1(1), Image of the target room Three options will be displayed under the message "Please select a background (p0)". The first method is "select from photo," in which the client U inputs a photo of the room he or she wishes to decorate taken with a digital camera, smartphone, etc. The other two options are "Choose from CG" and "Choose from sample images." First, let us assume that the client U selects "Select from photos." In this case, the client U will select the photos he or she has taken himself or herself. Image of the target room are uploaded to an online system and entered. In this embodiment, it is preferable that the photograph taken by the client U himself is taken looking directly at the fitting area so that preliminary correction work such as deforming the display area when fitting image data of the decorative element is not required. Of course, if it is difficult to take a photograph from the front, an actual photograph that has been corrected using appropriate image editing software can be used.

[0040] ii) If you select "Select from CG," enter the target indoor conditions. First, when using this system based on this CG image data, depending on the content of the CG image data, there may be a lack of information indicating the status of each of the room type, furniture, window size, floor, walls, curtain rail, etc. For this reason, the client U can input additional information to supplement the missing status as image content supplement information i1' and add it to the decoration preference information i1. In the operation screen of the embodiment shown in FIG. 4-2, for example, the room type options include a living room, a bedroom, and a children's room. As an example, the "furniture" options are displayed as typical colors of furniture pre-included in the room types, such as types A to E. For "window shape," options include waist window, bay window (narrow width), and bay window (wide width). Regarding the "floor," the color is indicated, and six options are presented: white, gray, natural, light brown, brown, and dark brown. Similarly, for "walls," colors are displayed and about six options are presented, including white, blue-green, and white-yellow. The "curtain rail" can be selected from functional rails, decorative rails, and curtain box types, and each is displayed with several color options ranging from white to dark brown.

[0041] III. Decoration preference input step i) Color selection When selecting a color, there is also an option to not express any preference. When selecting a color, the client U is presented with options from a palette, a photograph, or a sample, as shown in Figure 5-1. The palette shows a color chart from which the client U can specify their preferred color. Although not shown in the figure, if you are having trouble deciding on a color preference, you can select "From Photo" on the color chart, which will display a photo containing several tones and allow you to select a color in the photo with the cursor. "Sample" displays several specific curtain fabrics for you to choose from.

[0042] ii) Taste selection When selecting a taste, there is also an option to not express a preference. Tastes are extremely vague and difficult to define. Therefore, for each taste, multiple example images are displayed under titles such as "Natural," "Simple," and "Waterside." As shown in Figure 5-2, examples of tastes and categories listed in this example include language options such as natural, with green, simple, waterside, Nordic, vintage, classic, elegant classic modern, simple modern, and plain.

[0043] iii) Function selection Furthermore, the client U selects and inputs the functions he or she desires. The client U is also provided with the option to actively not select these functions. As for "function," in an example where the decorative element is curtain lace, as shown in Figures 5-3 and 5-4, options such as "flame retardant," "made in Japan," "European / American," "shaped," "washable," "contains natural materials," "antibacterial / bacteriostatic," "light blocking grade 1 A++," "light blocking grade 1 A+," "light blocking grade 1 (A) to (C)," and "light blocking grade 2" are displayed. Furthermore, in the case of a curtain, which is an example of a decorative element, the impression it gives varies greatly depending on the number of pleats that appear depending on the amount of fabric used, so it is also desirable to input the client U's request, such as standard, few, or many. Naturally, the final visual display proposal step s4 generates an inlaid image of the decorative element based on this request.

[0044] iv) Brand Selection If you click on the "All Brands" display, famous brands such as Company A, Company B, etc. will be displayed appropriately.

[0045] v) Price Display Prices are displayed according to the selections made by the client U in each of the steps above. It is preferable to input information to make a proposal that fits the client's budget.

[0046] vi) Code entry confirmation In this step, there is a special "product number specification" option, but you are also asked to select "OK" without specifying a product number. Details will be explained later, but this is a form for entering the code representation Ie' of a decorative element you liked during a simulation using this system. This will at least show it as an example of a decorative element proposed in the next step.

[0047] IV. Decorative element presentation and selection step s3 Based on the information input in the decoration preference input step s2, one or more decoration elements are appropriately proposed and displayed. As shown in Fig. 6, among the presented decoration elements, a decoration element that the client U is interested in is determined.

[0048] V. Visible display proposal step s4 In this step, when the "OK" selection is made, a composite image P is displayed on the screen in which the decorative specifications including the selected decorative element data Ie are applied to the position of the curtain in the target indoor image p0 that has already been input, as shown in Figure 7. At this time, it is possible to display a composite image P that appropriately reproduces the state of the curtain, such as a closed state, an open state, or a state in which the curtain has many pleats or few pleats. At this time, the system performs the following corrections to the color display on the display. Since residents are not always in close proximity to the curtains in real life, their naked eyes perceive colors that are slightly different from the actual color of the curtains. Therefore, for color elements, the system performs a sensitivity correction process on color data using various color representations, including strict RGB representations, to display a composite image P that reproduces the visual conditions taking into account the living position in the room. Furthermore, after viewing the simulation results displayed in the visual display suggestion step s4 based on the decision made in the decorative element presentation and selection step s3, it is possible to return to this decorative preference input step s2, select different suggested decorative elements, and display them for comparison. When the composite image P is displayed for comparison, an operation screen is also displayed on the drawing so that the client U can finally decide on the decorative specifications that he or she desires.

[0049] [Other application examples] The interior decoration plan of the present invention is typically intended for use with the curtains described above, but can also be applied to floors, walls, ceilings, furniture, and the like in a room.

[0050] Example of using AI In the above embodiment, after the client U himself / herself inputs the decoration preference information i1 and the environmental attribute information i2, the desired decoration elements are extracted from the contents of the room information obtained by the CPU in the computer, the cloud, etc., including an estimation of the client U's preferences based on color psychology, etc. However, in interior and spatial design, it is not always easy to express a design concept appropriately in words, and attempts are made to express or classify it more accurately by combining multiple modifiers. For example, a derived design concept has been defined, which is classified using the expression "neo-classical," combining "neo," which means "new," and "classic," which means "old-fashioned." For those who are not familiar with such constantly changing terminology, it is nearly impossible to convey one's decorative preferences using language alone. It is particularly difficult to convey the subtle nuances that encompass the elements of each design concept. Therefore, the target room information provided in step s1 is input. Image of the target room Using AI, it is possible to comprehensively consider data on each element of the room, such as the furniture, wallpaper, curtains, decorations, and posters, to infer client U's preferred decorative preferences and present decorative elements based on that. Of course, it is also possible to use AI to estimate decoration preferences based not only on the photographic data, but also on the decoration preference information i1 entered by the client U himself / herself in the decoration preference input step s2, and the environmental attribute information i2 added as part of the decoration preference information i1. Specifically, by analyzing actual images, the color tone, for example, whether the color is warm or cool, or further, regarding the color, brown, white, dark color, etc., the area proportion that each color occupies in the entire room is analyzed, and the preferences of client U are estimated. If the preferences of this client U are estimated using AI, it is possible to, for example, display one or more matching tastes, or display one or more colors that are judged to have a strong estimated preference tendency. Although this type of design taste determination is made by AI, it can discover expressions and colors that fit the tastes that client U was unable to express well. Of course, the AI ​​is based on the accumulated experience and knowledge of interior and space designers, and currently produces fairly accurate output results. This will enable Client U to use these expressions to more accurately consider decorative elements that suit their preferences.

[0051] <<About the input image calibration function>> In interior and spatial design, color specification, such as hue and saturation, is an important element, but it is extremely difficult to accurately grasp the color in a normal photograph. To accurately identify the color, it is necessary to perform color correction, such as white balance, in advance and to properly understand the characteristics of the room lighting. However, in the present invention, a photograph taken simply is input into the system, and it is extremely difficult to force the client U to take such strict photographs. Therefore, although not shown in the figure, client U may include a function that photographs an object (reference object) with accurate color information placed in the room, recognizes the object, and corrects the color of the entire photo based on the object's accurate color. Examples of such reference objects include relatively familiar everyday items such as bottles of soft drinks sold worldwide, bottles of well-known chemical seasonings, and PPC paper. Of course, other examples that can be applied include color charts developed by the Japanese Standards Association that are used to check the performance of color printers, and signboards with legally specified colors (signs indicating the presence of fire extinguishers as stipulated in the Fire Service Act, green signs indicating evacuation routes). By adding such a function, it is possible to accurately determine the preferences of the client U even from easily taken photograph data without placing an excessive burden on the client.

[0052] <<Operation without saving input data from Client U>> In the present invention, the room of the client U is photographed in the target room information providing step s1. Image of the target roomThe process starts when p0 is provided to the system. However, if the video of your room is provided to a system managed by someone else and stored there, it may be possible that the person who recorded the video of your room may be negligent due to a mistake on the part of the system administrator. Image of the target room It is also possible that p0 may leak to the outside. This is the usual system for taking pictures of rooms, etc. Image of the target room p0 is uploaded and input, and then the decorative elements determined by the client U are input in the visual display proposal step s4. Image of the target room p0, and then display the final image data that has been combined and embedded in it, and save the image data as appropriate to the client U's terminal, etc., before ending the use of this system. When this system confirms that the client U has finished using it, Image of the target room The data of p0, as well as the decoration preference information i1 and the like associated with the client U at that time, are immediately deleted. Basically, the use of this system is a one-time operation, and if you want to perform the simulation again, Image of the target room We need to start by uploading p0 to the system's recording device again. (Assistance when resimulating: Transfer of non-personal information) However, decorative preference information i1 (for example, desired curtain color, manufacturer, price, etc.) that cannot be considered personal can be saved in a data file called a cookie file, which is recorded when a web page is viewed, and the cookie file can be referenced when performing another simulation. (Assistance when resimulating: Code display of proposed decorative elements) Each decorative element proposed by this system is assigned a unique code representation Ie' and managed accordingly. Therefore, each decorative element presented in the decorative element presentation and selection step s3 is given a code representation, and by inputting this code representation as one piece of decoration preference information i1 when performing a simulation again as described above, it is possible to ensure that a decorative element that was previously proposed and that was favored is included as part of the decorative elements proposed again.

[0053] <Smooth transition to interpersonal consulting: Code displayed in part of composite image P> Furthermore, a timestamp t indicating the exact date and time of creation of the composite image P can be embedded in a part of the composite image P embodied and displayed in the target indoor image as characters or a two-dimensional barcode. This allows the client U to inform the system operator of this exact date and time of creation, and the system operator can then link the client U with the user's operation log, which is stored in a state where individuals cannot be identified, and access it. As a result, the operation log and the information provided by the client U can be Image of the target room It will be possible to hold more detailed discussions with dedicated staff while looking at p0 and composite photo P. The system operator can only link the operation log with a specific user upon receiving an inquiry from client U, which alleviates concerns about personal information leaks on the client U's side. On the other hand, by having client U come forward, the system also ensures the convenience of smooth interpersonal consulting. [Explanation of symbols]
