[0002] With the development of technology, virtual reality scenes are increasingly widely used in the real estate field, such as VR house viewing. By displaying a house through a virtual reality scene, users can more clearly and intuitively understand the internal structural layout and functional division of the house.

[0003] Currently, a three-dimensional model roaming method can be used to display a virtual reality scene. However, during the display process of the above virtual reality scene, when roaming the three-dimensional model, the rendering time of the three-dimensional model is relatively long, resulting in an overly long loading time for the virtual reality scene, and users cannot view the virtual reality scene of the target house in a timely manner. Summary of the Invention

[0019] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0021] Next, in conjunction with the attached Figures 1 to 9 , the virtual reality scene display method and device, electronic device, and readable storage medium provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0022] The execution subject of the technical solution of the virtual reality scene display method provided by the embodiments of the present application can be a virtual reality scene display device, which can be specifically determined according to actual usage requirements, and the embodiments of the present application do not make limitations. In order to more clearly describe the virtual reality scene display method provided by the embodiments of the present application, the following method embodiments will be exemplarily described with the execution subject of the virtual reality scene display method being a virtual reality scene display device.

[0023] As Figure 1 shown, in the embodiments of the present application, a virtual reality scene display method is provided, including the following steps S102 to S108:

[0024] Step S102, receiving a first input of a first display scheme for entering a target house.

[0025] Among them, the first display scheme is a three-dimensional roaming display scheme. When the target house is in the three-dimensional roaming display scheme, the user can comprehensively and stereoscopically view the internal structural layout and functional division of the target house by switching perspectives.

[0026] Further, the first input is the input operation of the user on the display interface of the target house under the current display scheme of the target house, or the first input is the input operation of the user on the indication identifier within the display interface of the target house under the current display scheme of the target house, wherein the above indication identifier is used to indicate the target house under the first display scheme. The virtual reality scene display device receives and responds to the first input operation of the user, and switches the display scheme of the target house from the current display scheme to the first display scheme.

[0027] Specifically, the above first input can specifically be the touch input of the user on the above display interface or indication identifier, and this touch input can specifically be single-click input, double-click input, long-press input, preset trajectory sliding input, etc., without specific limitation here.

[0028] Step S104, retrieve the target rendering image stored in the first storage area.

[0029] Among them, the target rendering image has an association relationship with the target house, and the target rendering image is the panoramic image of the target house. Specifically, when storing the target rendering image (i.e., the panoramic image of the target house) into the first storage area, the target rendering image can be named according to the name of the target house to establish the association relationship between the target rendering image and the target house. Based on the above association relationship, when receiving the first input to enter the first display scheme of the target house, the target rendering image stored in the first storage area is retrieved.

[0030] Specifically, the above panoramic image of the target house is an image obtained by shooting, or the above panoramic image of the target house is an image synthesized from multiple images, without specific limitation here.

[0031] Further, the first storage area is a local storage area, and all the images stored in the first storage area are images that have been successfully loaded. That is, the above target rendering image is the panoramic image of the target house that has been successfully loaded. In this way, when receiving the first input to enter the first display scheme of the target house, the panoramic image of the target house that has been successfully loaded is directly retrieved from the first storage area, without reloading the target rendering image, reducing the image loading time.

[0032] Step S106, perform texture mapping on the initial 3D model in the first display scheme according to the target rendering image to generate the target 3D model.

[0033] Among them, the target rendering image is the panoramic image of the target house. The initial 3D model in the first display scheme is texture-mapped with the panoramic image of the target house to perform 3D roaming on the initial 3D model, and then the target 3D model is obtained.

[0034] It is understandable that the initial 3D model is a 3D model without 3D roaming, and the target 3D model is a 3D model in the 3D roaming mode. When displaying the target house through the target 3D model, the user can comprehensively and stereoscopically view the internal structural layout and functional division of the target house by switching the display perspective of the target 3D model.

[0035] Furthermore, the initial 3D model is a 3D model established based on the feature points of the panoramic image of the target house. When establishing the initial 3D model based on the feature points of the panoramic image of the target house, the corresponding relationship between the initial 3D model and the panoramic image of the target house is established according to the above feature points, so as to perform texture mapping processing on the initial 3D model according to the corresponding relationship.

[0036] Step S108, in response to the first input, display the virtual reality scene through the target 3D model of the first display scheme.

[0037] Specifically, perform texture mapping processing on the initial 3D model in the first display scheme through the panoramic image of the target house, so as to perform 3D roaming on the initial 3D model to obtain the target 3D model, and then display the virtual reality scene of the target house through the target 3D model. In this display mode, the user can switch the display perspective of the virtual reality scene of the target house by switching the display perspective of the target 3D model, and then comprehensively and stereoscopically view the internal structural layout and functional division of the target house based on the virtual reality scene of the target house.

[0038] Through the above virtual reality scene display method provided by the embodiments of the present application, when receiving the first input for entering the first display scheme of the target house, directly retrieve the loaded target rendering image (panoramic image of the target house) associated with the target house stored in the first storage area to render the 3D model, perform texture mapping processing on the initial 3D model in the first display scheme according to the target rendering image to generate the target 3D model, and then display the virtual reality scene through the target 3D model of the first display scheme. In this way, during the rendering process of the 3D model, directly retrieve the loaded target rendering image associated with the target house to render the 3D model, without downloading the target rendering image of the target house, reducing the rendering time of the 3D model, thereby reducing the user's waiting time for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0039] In the embodiments of the present application, further, as Figure 2 shown, the above step S104 may specifically include the following steps S104a and S104b:

[0040] Step S104a: Confirm that the target house has been displayed through multiple rendered images in the second display scheme before receiving the first input.

[0041] Specifically, after receiving the first input for the first display scheme to enter the target house, confirm that the target house has been displayed through multiple rendered images in the second display scheme before receiving the above first input.

[0042] Among them, the multiple rendered images are panoramic images of the target house in different storage formats, and the multiple rendered images are stored in the above first storage area. That is, after receiving the first input for the first display scheme to enter the target house, confirm that before receiving the above first input, panoramic images of the target house that have been fully loaded are stored in the first storage area.

[0043] Furthermore, the second display scheme is a display scheme different from the first display scheme. Specifically, the second display scheme can be a panoramic display scheme, a two-dimensional display scheme, etc., which are not specifically limited here.

[0044] Step S104b: Determine and retrieve the target rendered image according to the identification information of the multiple rendered images.

[0045] Among them, the multiple rendered images are panoramic images of the target house in different storage formats, and the identification information is used to indicate the storage format of each rendered image. Specifically, the above identification information may include image information such as image name, image compression format, and image size that can be used to distinguish each rendered image. When it is confirmed that panoramic images of the target house that have been fully loaded (i.e., multiple rendered images) are stored in the first storage area before receiving the above first input, select the rendered image that meets the requirements as the target rendered image for retrieval according to the identification information of each rendered image.

[0046] In the above embodiment provided by the present application, after receiving the first input for the first display scheme to enter the target house, confirm that panoramic images of the target house that have been fully loaded (i.e., multiple rendered images) are stored in the first storage area before receiving the above first input, and then select the rendered image that meets the requirements as the target rendered image for retrieval according to the identification information of each rendered image. In this way, directly retrieve the panoramic image of the target house that has been loaded to render the 3D model, reducing the rendering time of the 3D model, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0047] In the embodiment of the present application, further, the above identification information includes name information. On this basis, as Figure 3 shown, the above step S104b may specifically include the following steps S104b1 to step S104b3:

[0048] Step S104b1: Traverse the name information of multiple rendered images stored in the first storage interval.

[0049] Among them, the multiple rendered images are panoramic images of the target house in different storage formats, and the identification information is used to indicate the storage format of each rendered image.

[0050] Specifically, the identification information includes name information. When it is confirmed that before receiving the above first input, panoramic images of the target house that have been loaded (i.e., multiple rendered images) are stored in the first storage interval, traverse the name information of the multiple rendered images stored in the first storage interval.

[0051] Step S104b2: Determine the target rendered image from the multiple rendered images according to the name information associated with the target house.

[0052] Specifically, the multiple rendered images are associated with the target house, and the multiple rendered images are the loaded panoramic images of the target house.

[0053] Specifically, when storing the multiple rendered images (i.e., the panoramic images of the target house) into the first storage interval, the multiple rendered images can be named according to the name of the target house to establish the association relationship between the multiple rendered images and the target house. Based on the above association relationship, when it is confirmed that before receiving the above first input, panoramic images of the target house that have been loaded (i.e., multiple rendered images) are stored in the first storage interval, determine the rendered image that meets the requirements as the target rendered image according to the name information of each rendered image.

[0054] Step S104b3: Retrieve the target rendered image from the first storage interval.

[0055] Specifically, after determining the rendered image that meets the requirements as the target rendered image according to the name information of each rendered image, directly retrieve the target rendered image from the first storage interval to render the 3D model.

[0056] In the above embodiments provided by the present application, when it is confirmed that before receiving the first input, panoramic images of the target house that have been loaded (i.e., multiple rendered images) are stored in the first storage interval, select the rendered image that meets the requirements as the target rendered image for retrieval according to the name information of each rendered image. In this way, directly retrieve the loaded panoramic image of the target house according to the name information to render the 3D model, ensuring the accuracy of retrieving the target 3D model. At the same time, it reduces the rendering time of the 3D model, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0057] In an embodiment of the present application, further, the multiple rendered images are compressed files loaded from a cloud server to a first storage area.

[0058] Specifically, when the panoramic image of the target house is loaded for the first time, that is, when the above-mentioned multiple rendered graphics are obtained for the first time, an image loading request is sent to the cloud server, and then the corresponding rendered images in the cloud server are loaded to the first storage area for local storage, and then the target rendered image is retrieved from the first storage area to render the 3D model.

[0059] Among them, the multiple rendered images are compressed files, that is, the multiple rendered images are images that have been compressed, specifically, the multiple rendered images are high-compression-rate images.

[0060] It can be understood that the compression rate of the rendered image is inversely proportional to the image quality of the rendered image, the image quality of the rendered image is directly proportional to the quality of the virtual reality scene, and the quality of the virtual reality scene is directly proportional to the rendering time of the 3D model.

[0061] That is to say, the higher the compression rate of the rendered image, the shorter the time required to render the 3D model through the rendered image, and the lower the compression rate of the rendered image, the longer the time required to render the 3D model through the rendered image.

[0062] In the above embodiment provided by the present application, the above-mentioned multiple rendered images are high-compression-rate images. In this way, when selecting a rendered image that meets the requirements from the multiple rendered images as the target rendered image to render the 3D model, the rendering time of the 3D model can be further reduced, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0063] In an embodiment of the present application, further, as Figure 4 shown, the above virtual reality scene display method may further include the following steps S110 and S112:

[0064] Step S110, confirm that the target house has not been displayed through a second display scheme before receiving the first input.

[0065] Specifically, after receiving the first input of the first display scheme for entering the target house, confirm that the target house has never been displayed through the second display scheme before receiving the above first input, that is, confirm that the panoramic image of the target house has not been loaded before receiving the above first input, that is, confirm that there is no panoramic image of the target house stored in the first storage area before receiving the above first input.

[0066] Among them, the second display scheme is a display scheme different from the first display scheme. Specifically, the second display scheme can be a panoramic display scheme or a two-dimensional display scheme, which is not specifically limited herein.

[0067] Step S112: Request the cloud server to load the first rendering material and render the initial 3D model according to the first rendering material.

[0068] Among them, the first rendering material is a panoramic image of the target house stored in the cloud server that has not been loaded.

[0069] Specifically, send a material loading request to the cloud server to request the loading of the first rendering material, receive the first rendering material sent by the cloud server, and render the initial 3D model according to the first rendering material.

[0070] Further, after receiving the first rendering material sent by the cloud server, name the first rendering material according to the name of the target house to establish a correspondence between the first rendering material and the target house, and then store the first rendering material in the above-mentioned first storage area for directly calling the first rendering material to render the 3D model next time.

[0071] Further, the first rendering material can be a compressed file loaded from the cloud server.

[0072] In the above embodiments provided by the present application, after receiving the first input of the first display scheme for entering the target house, it is confirmed that the panoramic image of the target house has not been loaded before receiving the above first input, and then the panoramic image of the target house is loaded from the cloud server to render the initial 3D model to obtain a virtual reality scene of the target house.

[0073] In the embodiments of the present application, further, as Figure 5 shown, the above step S106 may specifically include the following steps S106a and S106b:

[0074] Step S106a: Perform downsampling on the target rendering image to obtain a texture image.

[0075] It can be understood that the resolution of the target rendering image is inversely proportional to the image quality of the target rendering image, the image quality of the target rendering image is proportional to the quality of the virtual reality scene, and the quality of the virtual reality scene is proportional to the rendering time of the 3D model.

[0076] That is to say, the higher the resolution of the target rendering image, the longer the time required to render the 3D model through the target rendering image, and the lower the resolution of the target rendering image, the shorter the time required to render the 3D model through the target rendering image.

[0077] Step S106b: Texture the initial 3D model according to the texture image.

[0078] Specifically, the texture image is an image obtained by downsampling the target rendering image. Texturing the initial 3D model with the texture image for rendering the initial 3D model can further reduce the rendering time of the initial 3D model.

[0079] In the above embodiments provided by this application, the target rendering image is downsampled, and the initial 3D model is textured with the downsampled image for rendering the initial 3D model. In this way, the rendering time of the initial 3D model can be further reduced, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0080] In the embodiments of this application, further, as Figure 6 shown, the above step S106b may specifically include the following steps S106b1 to S106b3:

[0081] Step S106b1: Determine multiple first feature points in the initial 3D model.

[0082] Step S106b2: Determine multiple second feature points in the texture image.

[0083] Step S106b3: Paste the texture image onto the initial 3D model according to the multiple first feature points and the multiple second feature points.

[0084] Among them, the multiple first feature points and the multiple second feature points correspond one by one.

[0085] Specifically, the initial 3D model is a 3D model established according to the feature points of the panoramic image of the target house. When establishing the initial 3D model according to the feature points of the panoramic image of the target house, the corresponding relationship between the initial 3D model and the panoramic image of the target house is established according to the above feature points at the same time, that is, the feature points in the panoramic image of the above target house and the feature points in the initial 3D model correspond one by one.

[0086] In the above embodiments provided by the present application, according to multiple first feature points in the initial three-dimensional model and multiple second feature points in the texture map image, the texture map image is pasted on the initial three-dimensional model, wherein the multiple first feature points and the multiple second feature points correspond one by one. In this way, while ensuring the accuracy of the texture mapping process for the initial three-dimensional model, based on the one-to-one correspondence between the multiple first feature points and the multiple second feature points, the speed of the texture mapping process for the initial three-dimensional model is accelerated, thereby reducing the rendering time of the initial three-dimensional model and reducing the time for the user to wait for loading the virtual reality scene, ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0087] In the virtual reality scene display method provided by the embodiments of the present application, the execution subject may be a virtual reality scene display device. In the embodiments of the present application, taking the virtual reality scene display device executing the virtual reality scene display method as an example, the virtual reality scene display device provided by the embodiments of the present application is described.

[0088] As Figure 7 shown, in the embodiments of the present application, a virtual reality scene display device 700 is proposed. The virtual reality scene display device 700 is used to display a house graphic. The virtual reality scene display device 700 includes:

[0089] A receiving unit 702, configured to receive a first input of a first display scheme for entering a target house;

[0090] A processing unit 704, configured to retrieve a target rendering image stored in a first storage area, where the target rendering image has an association relationship with the target house;

[0091] The processing unit 704 is further configured to perform texture mapping processing on the initial three-dimensional model in the first display scheme according to the target rendering image to generate a target three-dimensional model;

[0092] A display unit 706, configured to respond to the first input and display a virtual reality scene through the target three-dimensional model of the first display scheme.

[0093] In the virtual reality scene display device 700 provided by the embodiment of the present application, when the receiving unit 702 receives the first input of the first display scheme for entering the target house, the processing unit 704 directly retrieves the loaded target rendering image (panoramic image of the target house) associated with the target house stored in the first storage area to render the three-dimensional model, performs texture mapping on the initial three-dimensional model in the first display scheme according to the target rendering image to generate the target three-dimensional model, and the display unit 706 then displays the virtual reality scene through the target three-dimensional model of the first display scheme. In this way, during the rendering process of the three-dimensional model, the loaded target rendering image associated with the target house is directly retrieved to render the three-dimensional model, without downloading the target rendering image of the target house, reducing the rendering time of the three-dimensional model, thereby reducing the time for the user to wait for loading the virtual reality scene, and ensuring that the user can promptly view the virtual reality scene of the target house.

[0094] In the embodiment of the present application, optionally, the processing unit 704 may specifically be used to: confirm that before receiving the first input, the target house has been displayed through multiple rendering images in the second display scheme, and the multiple rendering images are stored in the first storage area; determine and retrieve the target rendering image according to the identification information of the multiple rendering images.

[0095] In the embodiment of the present application, after the receiving unit 702 receives the first input of the first display scheme for entering the target house, the processing unit 704 confirms that before the receiving unit 702 receives the above first input, the panoramic images (i.e., multiple rendering images) of the target house that have been loaded are stored in the first storage area, and then according to the identification information of each rendering image, selects the rendering image that meets the requirements as the target rendering image for retrieval. In this way, the loaded panoramic image of the target house is directly retrieved to render the three-dimensional model, reducing the rendering time of the three-dimensional model, thereby reducing the time for the user to wait for loading the virtual reality scene, and ensuring that the user can promptly view the virtual reality scene of the target house.

[0096] In the embodiment of the present application, optionally, the identification information includes name information, and the processing unit 704 may specifically be used to: traverse the name information of the multiple rendering images stored in the first storage area; determine the target rendering image from the multiple rendering images according to the name information having an associated relationship with the target house; retrieve the target rendering image from the first storage area.

[0097] In the embodiment of the present application, when the processing unit 704 confirms that before the receiving unit 702 receives the first input, a panoramic image (i.e., multiple rendered images) of the target house that has been completely loaded is stored in the first storage area, the rendered images that meet the requirements are selected as the target rendered images for retrieval according to the name information of each rendered image. In this way, the panoramic image of the target house that has been loaded is directly retrieved according to the name information to render the 3D model, ensuring the accuracy of retrieving the target 3D model. At the same time, the rendering time of the 3D model is reduced, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0098] In the embodiment of the present application, optionally, the multiple rendered images are compressed files loaded from the cloud server to the first storage area.

[0099] In the embodiment of the present application, the above-mentioned multiple rendered images are high-compression-rate images. In this way, when selecting the rendered images that meet the requirements from the multiple rendered images as the target rendered images to render the 3D model, the rendering time of the 3D model can be further reduced, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0100] In the embodiment of the present application, optionally, the processing unit 704 is further configured to: confirm that the target house has not been displayed through the second display scheme before receiving the first input; request the cloud server to load the first rendering material, and render the initial 3D model according to the first rendering material.

[0101] In the embodiment of the present application, after the receiving unit 702 receives the first input of the first display scheme for entering the target house, the processing unit 704 confirms that before the receiving unit 702 receives the above-mentioned first input, the panoramic image of the above-mentioned target house has not been loaded, and then loads the panoramic image of the target house from the cloud server to render the initial 3D model to obtain the virtual reality scene of the target house.

[0102] In the embodiment of the present application, optionally, the processing unit 704 may specifically be configured to: perform a resolution reduction process on the target rendered image to obtain a texture image; perform a texture process on the initial 3D model according to the texture image.

[0103] In the embodiment of the present application, the processing unit 704 performs a resolution reduction process on the target rendered image, and then performs a texture process on the initial 3D model through the image after the resolution reduction process to render the initial 3D model. In this way, the rendering time of the initial 3D model can be further reduced, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0104] In an embodiment of the present application, optionally, the processing unit 704 may specifically be configured to: determine a plurality of first feature points in the initial three-dimensional model; determine a plurality of second feature points in the texture image, where the plurality of second feature points correspond one-to-one to the plurality of first feature points; and paste the texture image on the initial three-dimensional model according to the plurality of first feature points and the plurality of second feature points.

In this way, while ensuring the accuracy of the texture processing of the initial three-dimensional model, the speed of the texture processing of the initial three-dimensional model is increased according to the one-to-one correspondence between the plurality of first feature points and the plurality of second feature points, thereby reducing the rendering time of the initial three-dimensional model and reducing the waiting time for the user to load the virtual reality scene, ensuring that the user can view the virtual reality scene of the target house in a timely manner.

For the sake of brevity, it is not described again here.

[0110] It should be noted that the electronic devices in the embodiments of the present application include the above-mentioned mobile electronic devices and non-mobile electronic devices.

[0111] Figure 9 FIG. is a schematic diagram of the hardware structure of an electronic device for implementing an embodiment of the present application.

[0113] Those skilled in the art can understand that the electronic device 1000 may further include a power source (such as a battery) for supplying power to each component. The power source can be logically connected to the processor 1010 through a power management system, so as to implement functions such as management of charging, discharging, and power consumption management through the power management system.

The electronic device may include more or fewer components than shown, or combine certain components, or have different component arrangements, which are not described again here.

[0114] Among them, the user input unit 1007 is used to receive a first input of a first display scheme for entering a target house.

[0115] The processor 1010 is used to retrieve a target rendering image stored in a first storage area, and the target rendering image has an association relationship with the target house.

[0116] The processor 1010 is further used to perform texture mapping on the initial three-dimensional model in the first display scheme according to the target rendering image to generate a target three-dimensional model.

[0117] The display unit 1006 is used to display a virtual reality scene through the target three-dimensional model of the first display scheme in response to the first input.

[0118] In an embodiment of the present application, when the user input unit 1007 receives a first input for a first display scheme to enter a target house, the processor 1010 directly retrieves a loaded target rendering image (a panoramic image of the target house) associated with the target house stored in the first storage area to render a 3D model, performs texture mapping on the initial 3D model in the first display scheme according to the target rendering image to generate a target 3D model, and the display unit 1006 then displays a virtual reality scene through the target 3D model of the first display scheme. In this way, during the process of rendering the 3D model, the loaded target rendering image associated with the target house is directly retrieved to render the 3D model, without downloading the target rendering image of the target house, reducing the rendering time of the 3D model, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can promptly view the virtual reality scene of the target house.

[0119] Optionally, the processor 1010 may specifically be configured to: confirm that before receiving the first input, the target house has been displayed through multiple rendering images in a second display scheme, and the multiple rendering images are stored in the first storage area; determine and retrieve the target rendering image according to the identification information of the multiple rendering images.

[0120] In an embodiment of the present application, after the user input unit 1007 receives a first input for a first display scheme to enter a target house, the processor 1010 confirms that before the user input unit 1007 receives the above first input, a panoramic image (i.e., multiple rendering images) of the target house that has been completely loaded is stored in the first storage area, and then according to the identification information of each rendering image, selects a rendering image that meets the requirements as the target rendering image for retrieval. In this way, the loaded panoramic image of the target house is directly retrieved to render the 3D model, reducing the rendering time of the 3D model, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can promptly view the virtual reality scene of the target house.

[0121] Optionally, the identification information includes name information, and the processor 1010 may specifically be configured to: traverse the name information of the multiple rendering images stored in the first storage area; determine the target rendering image from the multiple rendering images according to the name information having an associated relationship with the target house; retrieve the target rendering image from the first storage area.

[0122] In the embodiments of the present application, when the processor 1010 confirms that before the first input is received by the user input unit 1007, a panoramic image (i.e., multiple rendered images) of the target house that has been completely loaded is stored in the first storage area, according to the name information of each rendered image, the rendered image that meets the requirements is selected as the target rendered image for retrieval. In this way, the panoramic image of the target house that has been loaded is directly retrieved according to the name information to render the three-dimensional model, ensuring the accuracy of retrieving the target three-dimensional model. At the same time, the rendering time of the three-dimensional model is reduced, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0123] Optionally, the multiple rendered images are compressed files loaded from the cloud server to the first storage area.

[0124] In the embodiments of the present application, the above multiple rendered images are high-compression-rate images. In this way, when selecting the rendered image that meets the requirements from the multiple rendered images as the target rendered image to render the three-dimensional model, the rendering time of the three-dimensional model can be further reduced, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0125] Optionally, the processor 1010 is further configured to confirm that the target house has not been displayed through the second display scheme before receiving the first input; request the cloud server to load the first rendering material, and render the initial three-dimensional model according to the first rendering material.

[0126] In the embodiments of the present application, after the user input unit 1007 receives the first input of the first display scheme for entering the target house, the processor 1010 confirms that before the user input unit 1007 receives the above first input, the panoramic image of the above target house has not been loaded, and then loads the panoramic image of the target house from the cloud server to render the initial three-dimensional model to obtain the virtual reality scene of the target house.

[0127] Optionally, the processor 1010 may specifically be configured to: perform a resolution reduction process on the target rendered image to obtain a texture image; and perform a texture process on the initial three-dimensional model according to the texture image.

[0128] In the embodiments of the present application, the processor 1010 performs a resolution reduction process on the target rendered image, and then performs a texture process on the initial three-dimensional model through the image after the resolution reduction process to render the initial three-dimensional model. In this way, the rendering time of the initial three-dimensional model can be further reduced, thereby reducing the time for the user to wait for loading the virtual reality scene and ensuring that the user can view the virtual reality scene of the target house in a timely manner.

[0129] Optionally, the processor 1010 may specifically be configured to: determine a plurality of first feature points in the initial three-dimensional model; determine a plurality of second feature points in the texture map image, where the plurality of second feature points correspond one-to-one to the plurality of first feature points; and paste the texture map image onto the initial three-dimensional model according to the plurality of first feature points and the plurality of second feature points.

[0130] In the embodiment of the present application, the processor 1010 pastes the texture map image onto the initial three-dimensional model according to the plurality of first feature points in the initial three-dimensional model and the plurality of second feature points in the texture map image, where the plurality of first feature points and the plurality of second feature points correspond one-to-one. In this way, while ensuring the accuracy of the texture mapping process for the initial three-dimensional model, the speed of the texture mapping process for the initial three-dimensional model is accelerated based on the one-to-one correspondence between the plurality of first feature points and the plurality of second feature points, thereby reducing the rendering time of the initial three-dimensional model and reducing the waiting time for the user to load the virtual reality scene, ensuring that the user can promptly view the virtual reality scene of the target house.
