[0037] In S100, furniture display scene information, user selection range information and target attribute information are obtained.

[0038] Specifically, the terminal device may first obtain furniture display scene information, user selection range information and target attribute information, wherein, for example, refer to Figure 2 The furniture display scene information includes the furniture model information to be replaced and the display background information; the furniture model information to be replaced is used to describe the furniture model of the appearance to be replaced; the display background information is used to describe the background of the furniture display scene information except the furniture model information to be replaced.

[0039] Without loss of generality, the user selection range information is used to describe the user's selection range; the target attribute information includes material attribute information, and the material attribute information is used to describe the surface material texture attributes of the furniture model information to be replaced; in a possible implementation, the target attribute information may also include color attribute information, and the color attribute information is used to describe the surface color attributes of the furniture model information to be replaced.

[0040] In S200, target display area information is generated according to the model information of the furniture to be replaced and the user's selected range information.

[0041] Specifically, after the terminal device obtains the furniture display scene information, the user selection range information and the target attribute information, the terminal device can generate the target display area information according to the model information of the furniture to be replaced and the user selection range information, thereby determining the part of the furniture whose material the user needs to change, wherein the target display area information is used to describe the overlapping part between the model information of the furniture to be replaced and the user selection range information.

[0042] In S300, target furniture model information is generated according to the target display area information and the target attribute information.

[0043] Specifically, after the terminal device generates the target display area information, the terminal device may generate the target furniture model information according to the target display area information and the target attribute information.

[0044] In S400, target display scene information is generated according to the target furniture model information and the display background information.

[0045] Specifically, after the terminal device generates the target furniture model information, the terminal device can effectively generate the target display scene information based on the target furniture model information and the display background information, thereby displaying furniture models that meet personalized needs to users, while displaying furniture models and their backgrounds that fit the real scene to users, further improving the user experience.

[0046] In some possible implementations, in order to obtain furniture display scene information, user selection range information and target attribute information, and to facilitate the subsequent satisfaction of users' personalized needs and improve the user experience, please refer to Figure 3 Step S100 includes but is not limited to the following steps:

[0047] In S110, furniture display scene information is obtained based on a preset furniture model database.

[0048] Specifically, the terminal device can obtain furniture display scene information based on a preset furniture model database, wherein the furniture model database is used to store multiple furniture models and the background corresponding to each furniture model.

[0049] In S120, the user selection range information is obtained.

[0050] Specifically, after the terminal device obtains the furniture display scene information, the terminal device can obtain the user selection range information; without loss of generality, the user selection range information includes global range information or local range information, wherein the global range information is used to describe the user's selection range as the entire furniture model, and the local range information is used to describe the user's selection range as a part of the furniture model.

[0051] In some possible implementations, in order to accurately determine the global range information and obtain valid user selected range information, step S120 includes but is not limited to the following steps:

[0052] In S1201, based on a preset default replacement mode, it is determined that the user-selected range information is global range information.

[0053] Specifically, the terminal device can determine that the user-selected range information is global range information based on a preset default replacement mode, thereby facilitating the subsequent overall replacement of the material attributes or color attributes of the furniture model, wherein the default replacement mode is used to describe the default mode of the application when determining the user-selected range information. For example, when the user does not initiate a click action on the furniture model information to be replaced, the terminal device can determine that the current mode is the default replacement mode.

[0054] In some possible implementations, in order to accurately determine the local range information and further obtain the effective user selection range information, please refer to Figure 4 Step S120 includes but is not limited to the following steps:

[0055] In S121, in response to the user click information, the user selection path information is obtained.

[0056] Specifically, the terminal device can obtain user selection path information in response to user click information, where the user click information is used to describe the user's click action on the furniture model information to be replaced, and the user selection path information is used to describe the selection path generated based on the user operation.

[0057] In S122, the user selection range information is determined according to the user selection path information.

[0058] Specifically, after the terminal device obtains the user's selection path information, the terminal device can quickly determine the user's selection range information based on the user's selection path information. For example, see Figure 5 In (b), the user selection range information is used to describe the closed area enclosed by the user selection path information.

[0059] For example, see Figure 5 (a) Figure 5 (b) and Figure 5 In (c), the terminal device responds to the user's click information and continuously obtains the user's operation information until the user's selection path information is obtained, and then determines the user's selection range information based on the user's selection path information, and then replaces the surface material of the part selected by the user in the furniture model information to be replaced with the basic material selected by the user, and displays the furniture model after the material replacement to meet the personalized needs of some users.

[0060] In S130 , sample material image information is obtained.

[0061] Specifically, after the terminal device determines the user's selection range information, the terminal device can obtain sample material image information. For example, see Figure 6 In (a), the example material image information is used to describe an exemplary material image, and the terminal device can obtain the image uploaded by the user to the preset material database.

[0062] In S140, target object information is generated according to the example material image information and a preset target detection algorithm.

[0063] Specifically, after the terminal device obtains the sample material image information, the terminal device can determine the object in the sample material image information according to the sample material image information and a preset target detection algorithm, and generate target object information, wherein the target detection algorithm can be a target detection algorithm based on R-CNN (Region-based Convolutional Neural Networks) or a target detection algorithm based on SSD (Single Shot MultiBox Detector); for example, please refer to Figure 6 In (a), the terminal device can determine that the object in the example material image information is a handbag based on the example material image information and the target detection algorithm based on R-CNN.

[0064] In S150, the object outer contour information is generated according to the target object information and a preset edge detection algorithm.

[0065] Specifically, after the terminal device generates the target item object information, the terminal device can determine the edge contour of the target item object information based on the target item object information and a preset edge detection algorithm, and generate the item object outer contour information, wherein the edge detection algorithm can be an edge detection algorithm based on a Sobel operator or an edge detection algorithm based on a Prewitt operator; the item object outer contour information is used to describe the outer contour of the target item object information.

[0066] In S160, the sampling frame range information is determined according to the outer contour information of the object.

[0067] Specifically, after the terminal device generates the object outer contour information, the terminal device can effectively determine the sampling frame range information according to the object outer contour information. For example, see Figure 7 The sampling frame range information is used to describe an inscribed rectangular frame whose corner points conflict with the outer contour information of the object. In a possible implementation, the sampling frame range information can also be an irregular closed frame with a side length of four, whose corner points conflict with the outer contour information of the object.

[0068] In S170 , material attribute information is determined based on the sample material image information and the sampling frame range information.

[0069] Specifically, after the terminal device determines the sampling frame range information, the terminal device can determine the material attribute information based on the example material image information and the sampling frame range information, thereby determining the personalized material required by the user.

[0070] For example, see Figure 6 (a) Figure 6 (b) and Figure 6 In (c), the terminal device first obtains the sample material image information uploaded by the user, then determines the surface material corresponding to the handbag in the sample material image information, and finally replaces the surface material of the part selected by the user in the furniture model information to be replaced with the surface material corresponding to the handbag, intuitively displaying the furniture model after the material replacement to meet the personalized needs of more users.

[0071] In some possible implementations, in order to generate the target furniture model information, step S300 includes but is not limited to the following steps:

[0072] In S310, based on a preset mapping algorithm, the target attribute information is mapped to the target display area information to generate the target furniture model information.

[0073] Specifically, the terminal device may map the target attribute information to the target display area information based on a preset mapping algorithm, so as to apply the target attribute information to the surface of the target display area information and generate the target furniture model information.

[0074] In one possible implementation, the terminal device can also use Image Rembg to determine the subject corresponding to the furniture model whose appearance is to be changed, and then use Depth Anything to convert the subject into a depth map, and then use IPAdapter to transfer the style of the material image selected or uploaded by the user to the subject, and finally perform a second fusion of the fused subject and the original background.

[0075] Accordingly, see Figure 8 The above step S400 includes but is not limited to the following steps:

[0076] In S410, based on the display background information, pixel brightness value information corresponding to a plurality of display background pixels is obtained.

[0077] Specifically, after the terminal device generates the target furniture model information, the terminal device can obtain pixel brightness value information corresponding to multiple display background pixels based on the display background information, wherein the display background pixels are used to describe the pixels in the display background information, and the pixel brightness value information is used to describe the brightness values ​​of the display background pixels.

[0078] In S420, brightness difference information is generated according to the difference between the first brightness value information of the first background pixel and the second brightness value information of the second background pixel.

[0079] Specifically, after the terminal device obtains the pixel brightness value information, the terminal device can generate brightness difference information based on the difference between the first brightness value information of the first background pixel and the second brightness value information of the second background pixel, wherein the first background pixel is used to describe any display background pixel; the first brightness value information is used to describe the pixel brightness value information corresponding to the first background pixel; the second background pixel is used to describe any display background pixel adjacent to the first background pixel; and the second brightness value information is used to describe the pixel brightness value information corresponding to the second background pixel.

[0080] In S430, the brightness difference information is compared with the preset phase difference threshold information.

[0081] Specifically, after the terminal device generates the brightness difference information, the terminal device may compare the brightness difference information with the preset phase difference threshold information.

[0082] In S440, if the brightness difference information is greater than the phase difference threshold information, the display background pixel point with smaller pixel brightness value information is determined as shadow pixel point information.

[0083] Specifically, if the brightness difference information is greater than the phase difference threshold information, the terminal device can determine the display background pixel with smaller pixel brightness value information from the first background pixel and the second background pixel as the shadow pixel information, where the shadow pixel information is used to describe the pixel corresponding to the shadow area.

[0084] In S450, shadow area feature information is generated based on the display background information and the information of multiple shadow pixels.

[0085] Specifically, after the terminal device determines the shadow pixel information, the terminal device can generate shadow area characteristic information based on the display background information and multiple shadow pixel information, wherein the shadow area characteristic information is used to describe the shadow direction information and the maximum shadow length information, the shadow direction information is used to describe the corresponding extension direction of the shadow area, and the maximum shadow length information is used to describe the maximum extension length corresponding to the shadow area.

[0086] In S460, simulated light source information is generated according to the shadow direction information and the shadow length maximum value information.

[0087] Specifically, after the terminal device generates shadow area characteristic information, the terminal device can generate simulated light source information based on the shadow direction information and the maximum shadow length information, thereby realizing the reverse deduction of the simulated light source in the display background information based on the shadow characteristics in the display background information, wherein the simulated light source information is used to describe the simulated light source.

[0088] In S470, optimized furniture model information is generated based on the simulated light source information and the target furniture model information.

[0089] Specifically, after the terminal device generates simulated light source information, the terminal device can highly match the light intensity of the display background information of the target furniture model information based on the simulated light source information and the target furniture model information, and generate optimized furniture model information, thereby improving the display effect of the optimized furniture model information.

[0090] In S480, target display scene information is generated according to the optimized furniture model information and the display background information.

[0091] Specifically, after the terminal device generates the optimized furniture model information, the terminal device can effectively generate the target display scene information according to the optimized furniture model information and the display background information.

[0092] In some possible implementations, in order to facilitate users to view historical furniture appearance simulation results at any time, please refer to Fig. 9 After step S400, the method further includes but is not limited to the following steps:

[0093] In S500, first generation time information of target furniture model information and second generation time information of target display scene information are obtained.

[0095] In S510, the target furniture model information, the first generation time information, the target display scene information and the second generation time information are uploaded to a preset history database.

[0096] Specifically, after the terminal device obtains the first generation time information and the second generation time information, the terminal device can upload the target furniture model information, the first generation time information, the target display scene information and the second generation time information to a preset historical database, so that the user can view the historical furniture appearance simulation results at any time through the historical database, wherein the target furniture model information is associated with the first generation time information, and the target display scene information is associated with the second generation time information.

[0097] The implementation principle of the simulation display method applied to the furniture appearance in the embodiment of the present application is as follows: the terminal device can first obtain the furniture display scene information, the user selection range information and the target attribute information, and then quickly generate the target display area information according to the furniture model information to be replaced and the user selection range information, and then effectively generate the target furniture model information according to the target display area information and the target attribute information, and finally efficiently generate the target display scene information according to the target furniture model information and the display background information, so that the user can personalize the material of the furniture appearance, meet the user's needs for personalized design of furniture, and improve the user's usage experience.
