[0051] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects described may be practiced without these specific details.

[0052] The embodiment of the present invention provides a three-dimensional visualization method for a hotel room, referring to Figure 1 , 2 As shown, Figure 1 A schematic diagram of a process flow of a three-dimensional visualization method for a hotel room provided by an embodiment of the present invention; Figure 2 This is an overall architecture diagram of a three-dimensional visualization method for hotel rooms provided in an embodiment of the present invention, and its architecture mainly includes a mobile terminal and a server.

[0053] The three-dimensional visualization method of a hotel room in an embodiment of the present invention mainly includes the following steps S110-S150, and steps S110-S150 are mainly described from the perspective of a server.

[0054] Step S110, receiving the basic model and corresponding scanning parameter data uploaded by the mobile terminal; the basic model is generated by scanning the hotel room based on RoomPlan by the mobile terminal with LiDAR; the scanning parameter data includes key parameters, and the key parameters include the size of the room and the size, position, direction and classification of the furniture in the room.

[0055] The data received in this step comes from the mobile terminal. It is necessary to generate a basic model and corresponding scanning parameter data on the mobile terminal. The generation of the basic model can be based on the secondary development of RoomPlan. Specifically, users can use mobile devices with LiDAR, such as iPhones, to scan hotel rooms based on RoomPlan, and then upload the data to the server. Through the above processing, a simple three-dimensional visualization model of a hotel room can be generated quickly, accurately, and at low cost.

[0056] To describe the scanning steps on the mobile terminal in more detail, let's take a real scenario as an example. Suppose a user wants to upload a real 3D simple model of the hotel room for real user reviews after staying in a hotel. The first step is to take the hotel room scene quick scanning steps:

[0057] Specifically, it can be integrated into existing iPhones with LiDAR. After the user clicks the model scanning button in the software application, he can jump into a secondary development scanning page based on RoomPlan. After clicking Start Scan on this page, the real-time modeling of the room is started. The user can intuitively see the room construction process in real time on the page, including the size and location information of the room, furniture, etc. At the bottom of the page, the basic model of the room constructed in real time can be seen (reference Figure 3 shown).

[0058] Depending on the complexity of the room, the scanning time ranges from 5 to 10 minutes. Thanks to the LiDAR algorithm and machine learning algorithm, the precise size of the room and the precise size and position of the main furniture in the room can be obtained. After a lot of practice, the information error between the model and the real room is less than 5%.

[0059] In the above steps, secondary development was carried out based on RoomPlan, which enabled the basic model of the room to be quickly and accurately constructed in real time with only a mobile device equipped with LiDAR. The cost is extremely low, and RoomPlan is Apple's official framework technology, which can be continuously upgraded and iterated.

[0060] After the user scans the basic model, he can click the upload button to upload the basic model and scanning parameter data to the server. The basic model parameters store the size information of the room and the size, position, direction, classification, etc. of the furniture in the room. As a preferred embodiment, the key parameters also include a detailed description of the classification object corresponding to the classification.

[0061] Of course, the above scenario can also be changed to a situation where hotel-related personnel need to upload a real 3D simple model of the hotel room. By uploading the model, users can intuitively understand the actual layout of the room, reduce the situation where the reservation does not match the actual situation, improve the accuracy of the user's reservation decision, and enhance the user experience.

[0062] Next, go to step S120 to extract the key parameters.

[0063] Furthermore, after extracting the key parameters, standardized data format processing is performed to change them into a standardized data format.

[0064] Next, go to step S130 to search for a matching standardized model in the model library based on the extracted key parameters.

[0065] Specifically, the server is mainly responsible for standardizing and replacing furniture in the basic model. For example, the dining chair in the basic model is displayed as a rectangular block of the same size as the dining chair. The main task of server standardization is to match and replace the rectangular block with a standard simple model of the dining chair. This is because it can give users the most intuitive experience of the furniture.

[0066] refer to Figure 4 As shown, in addition to its own position and size, the furniture model in the basic model also carries category and attributes. Category is used for classification, such as sofa, bed, locker, etc. Attributes are a more detailed description of a category. For example, category is chair, which means a chair, and attributes are (ChairLegType: four; ChairBackType: existing; ChairType: dining; ChairArmType: missing), which respectively represent a dining chair with four legs and a normal backrest. The server can match a standard model in the model library based on this information, which can be used to replace the rectangular model in the basic model.

[0067] The above only takes chairs as an example. In fact, there are many other types, which will not be elaborated here.

[0068] This embodiment uses advanced machine learning algorithms for the categories and attributes of furniture in the room, and the subsequent optimization direction is to increase the types and details of recognition.

[0069] Next, go to step S140, and place the matched standardized model into the original position in the base model according to the original size and orientation for replacement.

[0070] In this step, the core task of model standardization replacement is to place the matched standardized model in the correct position of the base model according to the original direction and size through the standardization algorithm. First, scale the model to its original size, then place it back to its original size, and rotate the model to keep it consistent with the direction in the real scene.

[0071] In addition to completing the model matching and replacement of the aforementioned steps S130 and S140, another core function of the server is the management of the model library, which is rich and dynamic. The more detailed the basic model parameters are, the closer the standard model output by the server is to the real scene.

[0072] The management of the model library mainly includes: classifying and managing different types of furniture models in the model library and providing model version control.

[0073] Model version control is mainly used to optimize the size of model files in the model library.

[0074] The core function of the hotel room 3D model produced by the embodiment of the present invention is to accurately describe the room's size information and space furniture layout. It does not pursue a high degree of scene restoration, but needs to spread a large number of simple 3D models in the Internet environment. Therefore, it is necessary to ensure the file size of the model in order to provide a better user experience.

[0075] In order to ensure that the model file size is smaller, the models in the model library maintained by the server are expressed only with simple shapes and colors, without using high-precision materials, in order to optimize the model file size.

[0076] Preferably, in order to automate the management of the model library, the model uploaded to the model library can be automatically tested for the file volume and triangulation description of the model through the model verification algorithm, and only models that meet the test requirements (such as less than the first preset value) are allowed to be uploaded.

[0077] In short, the models in the model library need to strictly control the model file size and balance the model details and size.

[0078] In addition, the model library preferably uses a machine learning algorithm to optimize matching accuracy.

[0079] Next, go to step S150: send the replaced basic model to the mobile terminal.

[0080] After the replaced basic model is sent to the mobile terminal, the mobile terminal renders the model. Preferably, the model is optimized for rendering before being sent to the mobile terminal.

[0081] At this point, taking the aforementioned review example as an example, the user can decide whether to send a model review based on the rendered effect.

[0082] From the above, a complete 3D visualization process of hotel rooms based on mobile devices is completed. Figure 5 It shows an original picture of a hotel room and a 3D visualization view generated based on it.

[0083] In summary, the core principle of the embodiment of the present invention is to conduct secondary development of RoomPlan, so that users can use mobile devices with LiDAR, such as mobile phones, to complete a quick scan of the hotel room, and then upload the data to the server, which completes the model matching and forms a three-dimensional visualization model of the hotel room. The present invention uses the mobile devices of ordinary users to quickly and accurately generate a standardized three-dimensional visualization simple model of the hotel room, which can ensure that the three-dimensional simple model can accurately express the spatial furniture layout and size information of the hotel room, and achieve low cost and rapid construction of the three-dimensional simple model. At the same time, Internet transmission is further considered to ensure that the file size of the scanned model is convenient for transmission on the Internet.

[0084] The three-dimensional visualization method for hotel rooms provided in the embodiment of the present invention can significantly reduce the production cost of room models. It does not require professional equipment and uses users' ordinary mobile devices to collect data, and automates the processing process to reduce labor costs; standardizes the model library to avoid repeated modeling. The present invention can significantly improve the efficiency of room modeling, quickly collect, and realize the timely update of room space layout information, supporting large-scale application and promotion. The present invention can improve the user experience, and users can intuitively understand the actual layout of the room, reduce the situation where the reservation does not match the actual situation, and improve the accuracy of the user's reservation decision.
