[0045] Figure 1 A schematic diagram of an exemplary system architecture to which the three-dimensional scene construction method of the embodiments of the present disclosure can be applied is shown; as Figure 1

[0046] The system architecture can include a server 101, a network 102 and a client 103. The network 102 is used as a medium to provide a communication link between the client 103 and the server 101. The network 102 can include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0047] The server 101 can be a server that provides various services, such as a background management server that provides support for the operations of the user using the client 203. The background management server can construct an initial three-dimensional scene of the target entity scene according to the scene image data, and can also receive and process device construction instructions, display the corresponding device model in the initial three-dimensional scene displayed in the corresponding interface of the client 203 based on the device construction instructions, and further generate and display a three-dimensional scene with a device construction effect in the corresponding interface of the client 203.

[0048] ​In some optional embodiments, the server 101 can acquire scene image data of a target entity scene, parse sensing information in the scene image data to generate a spatial coordinate system corresponding to the scene image data; the server 101 can identify a surface object in the scene image data, construct an initial three-dimensional scene of the target entity scene in the spatial coordinate system based on the surface object; the server 101 can acquire an actual distance parameter value in the target entity scene, determine size information of the initial three-dimensional scene according to the actual distance parameter value; the server 101 can acquire a device construction instruction, determine a device model applied to the initial three-dimensional scene and a corresponding placement position according to the device construction instruction; and the server 101 can display the device model in the initial three-dimensional scene according to the placement position, thereby generating a three-dimensional scene with a device construction effect.

[0049] The client 103 can be a mobile terminal such as a mobile phone, a game console, a tablet computer, an e-book reader, smart glasses, a smart home device, an AR (Augmented Reality) device, a VR (Virtual Reality) device, or the like, or the client 103 can also be a personal computer such as a laptop computer and a desktop computer, and the like.

[0050] In some optional embodiments, the client 103 can display the initial three-dimensional scene of the target entity scene to an operator, and can also provide an interface for the operator to issue a device construction instruction, and can display the three-dimensional scene with the device construction effect to the operator.

[0051] It should be understood that Figure 1 The number of clients, networks and servers in the server 101 is only illustrative, and the server 101 can be a server of one entity, or can be a server cluster composed of multiple servers, or can be a cloud server, and can have any number of clients, networks and servers according to actual needs.

[0052] In the following, each step of the wiring method based on the three-dimensional scene in the example embodiments of the present disclosure will be described in more detail in combination with the accompanying drawings and embodiments.

[0053] Figure 2 A flowchart of a three-dimensional scene construction method of an embodiment of the present disclosure is shown. The method provided by the embodiment of the present disclosure can be executed by a server or a client as shown in Figure 1 but the present disclosure is not limited thereto.

[0054] In the following example illustration, the server cluster 101 is taken as an example to illustrate the execution subject.

[0055] As Figure 2As shown, the three-dimensional scene construction method provided by the embodiments of the disclosure can include the following steps:

[0056] In step S201, scene image data of a target entity scene is acquired, and sensing information in the scene image data is parsed to generate a spatial coordinate system corresponding to the scene image data.

[0057] In this embodiment, the target entity scene can be a specific machine room, a server storage room, a workspace, etc. The scene image data can be a multimedia file in the form of a video, an animated image, an image set, etc. The scene image data can be obtained by using an image acquisition device with a sensing device to perform image acquisition on the target entity scene, for example, a mobile phone camera can be used to take a picture of the scene to obtain a video, an animated image, an image set, etc. of the target entity scene.

[0058] In step S203, a surface object in the scene image data is identified, and an initial three-dimensional scene of the target entity scene is constructed in the spatial coordinate system based on the surface object. The surface object can be a wall, a top surface, etc. in the target entity scene. The initial three-dimensional scene can be a virtual scene embodiment of the target entity scene without device decoration, for example, the initial three-dimensional scene can be a virtual scene composed of four walls, a top surface, and a bottom surface.

[0059] In step S205, an actual distance parameter value in the target entity scene is acquired, and the size information of the initial three-dimensional scene is determined according to the actual distance parameter value. The actual distance parameter value can be information actually used to describe the size of the target entity scene, such as size information of each wall surface, height information in the scene, etc.

[0060] In step S207, a device construction instruction is acquired, and a device model applied to the initial three-dimensional scene and a corresponding placement position are determined according to the device construction instruction. The device construction instruction can be issued by a user in a corresponding operation interface displayed on the client 103. The device construction instruction can indicate the type or style of the device that the user wants to place, and can indicate the position in the initial three-dimensional scene where the user wants to place the device model.

[0061] In step S209, the device model is displayed in the initial three-dimensional scene according to the placement position, and a three-dimensional scene with a device construction effect is generated. In this embodiment, the device model specified by the user can be visualized and placed in the constructed initial three-dimensional scene in response to the device construction instruction, and the three-dimensional scene with the device construction effect is displayed to the user, so that the scene effect is intuitively presented.

[0062] The three-dimensional scene construction method provided by the embodiment of the present disclosure can construct an initial three-dimensional model of a target entity scene, and can quickly respond to a device construction instruction of a user to display a device model in the initial three-dimensional model, thereby generating a corresponding scene effect and display. The construction period is short, easy to modify, and can quickly respond to customer requirements for scene display.

[0063] In some embodiments, the scene image data includes a plurality of images; and the step of analyzing the sensing information in the scene image data to generate a space coordinate system corresponding to the scene image data includes: analyzing the sensing information in the scene image data to obtain relative position information of the images in the scene image data and three-dimensional direction information corresponding to the images; and generating the space coordinate system corresponding to the scene image data according to the relative position information and the three-dimensional direction information.

[0064] The scene image data can include sensing information, such as sensing information obtained by using an accelerometer and a gyroscope. For example, the relative positions of the images in the scene image data can be identified by using a mobile phone camera and a sensor, and then the X, Y, and Z three axes for the initial three-dimensional scene can be labeled.

[0065] Figure 3 FIG. 4 shows a schematic diagram of generating a space coordinate system in the three-dimensional scene construction method of one embodiment of the present disclosure, as shown in Figure 3 FIG. 5 shows a schematic diagram of a space coordinate system with three-dimensional directions generated in a scene image, which includes X, Y, and Z three axes.

[0066] Figure 4 FIG. 6 shows a flowchart of constructing an initial three-dimensional scene in the three-dimensional scene construction method of one embodiment of the present disclosure, as shown in Figure 4 Figure 2 The step S203 in the embodiment can further include the following steps:

[0067] In step S401, feature points on each image in the scene image data are determined by using augmented reality (AR) technology, and a surface object in the scene image data is identified according to the feature points. The surface object can be, for example, four wall surfaces (or a plurality of wall surfaces), one ground surface, one top surface, and a plurality of surfaces.

[0068] In step S403, the positions of the surface objects in the space coordinate system corresponding to the scene image data are determined based on the space coordinate system.

[0069] In step S405, an initial surface model of the surface object is constructed according to the position of the surface object in the space coordinate system. In step S405, the position of the surface object in the space coordinate system is determined based on the generated space coordinate system, the boundary of the target entity scene is labeled, and then the initial surface model of the surface object is created. ​

[0070] Step S407, the initial surface model is optimized by a nonlinear fitting technique to obtain a target surface model, and then an initial three-dimensional scene of the target entity scene is constructed according to the target surface model.

[0071] It can be seen that, by implementing the above steps, the surface recognition and recording in the target entity scene can be completed through feature point recognition in the scene image, and the virtual initial three-dimensional scene can be created. Figure 4 Specifically, the space recognition of the IDC machine room in reality can be realized by using a mobile phone camera, a sensor and the like in an AR mode, in combination with image recognition and a nonlinear fitting method, and then the above initial three-dimensional scene can be built.

[0072] Figure 5 A flowchart of obtaining a target surface model in a three-dimensional scene construction method of one embodiment of the present disclosure is shown in FIG. 4, which shows that Figure 5 the step S407 in the embodiment can further include the following steps: Figure 4

[0073] Step S501, a mesh object corresponding to the initial surface model is created in the initial three-dimensional scene. In some actual applications, a semi-transparent mesh can be created in the initial three-dimensional scene through an application program in a mobile device (such as a mobile phone).

[0074] Step S503, the mesh object is fitted on the corresponding initial surface model to generate labeling information of the initial surface model. In some actual applications, the created semi-transparent mesh can be fitted onto the ground or wall through the above-mentioned related application program to realize the labeling of the surface.

[0075] Step S505, the initial surface model is spliced based on the labeling information by a nonlinear fitting technique to obtain a target surface model. The nonlinear fitting function provided in the above-mentioned related application program (for example, the function provided by the Ceres library in the application program) can be used to realize the splicing of the surface, and a virtual surface more consistent with the actual scene is generated as the target surface model.

[0076] It can be seen that, by implementing the above steps, Figure 5 the semi-transparent mesh can be created in the initial three-dimensional scene and fitted onto the ground or wall, the nonlinear fitting and the splicing of the surface can be completed, and then the accuracy of the surface recognition and labeling in the initial three-dimensional scene can be improved.

[0077] Figure 6 A schematic diagram of creating a mesh object in a three-dimensional scene construction method of one embodiment of the present disclosure is shown in FIG. 5, which shows that Figure 6 the step S501 in the embodiment can further include the following steps: Figure 5 ​The schematic diagram of step S501 in the embodiment in an actual application includes: creating mesh objects 601, 602, 603, and 604 in an initial three-dimensional scene 600. The initial three-dimensional scene 600 and the mesh objects 601, 602, 603, and 604 can be presented by an application program on a mobile device (such as a mobile phone).

[0078] Figure 7 The schematic diagram of labeling the initial surface model in the three-dimensional scene construction method of one embodiment of the present disclosure is shown in FIG. 6B. As shown in FIG. 6B, the initial surface model is labeled as a wall surface 601, a floor surface 602, and an invalid surface 603. Figure 7 Figure 5 The schematic diagram of step S503 in the embodiment in an actual application includes: a mobile device 700, an operation interface 701 provided by an application program on the mobile device 700, an operation button 702 for labeling in the operation interface 701, and a mesh object 703 presented in the operation interface 701. By implementing Figure 7 The schematic diagram shown in FIG. 6D can present the initial three-dimensional scene and the mesh object 703 through the operation interface 701 provided by the application program in the mobile device 700 (such as a mobile phone), and can also provide the operation button 702 for labeling in the operation interface 701, so that the user can perform corresponding operations on the operation button 702 to label the mesh object 703. Further, in the present schematic diagram, the operation button 702 can include labeling operation buttons for a wall surface, a floor surface, and an invalid surface, as shown in FIG. 6D. The user can slide the mesh object 703 by holding the labeling operation button for the wall surface, and at this time, a prompt information “drag to label as a wall surface” can appear in the operation interface 701. Figure 7

[0079] In some actual applications, if there are devices (such as cabinets, computer desks, etc.) or decoration facilities in the target entity scene, the surfaces of the devices (such as cabinets, computer desks, etc.) or decoration facilities can be ignored in the process of labeling the initial surface model, and mesh objects are not created on these surfaces, and labeling operations are not performed on these surfaces.

[0080] In some embodiments, Figure 2 The step of acquiring the actual distance parameter value in the target entity scene in step S205 in the embodiment includes: using an image acquisition device with a sensing device to measure the distance in the target entity scene to obtain the actual distance parameter value in the target entity scene; and / or acquiring the architectural design data of the target entity scene, and determining the actual distance parameter value in the target entity scene according to the architectural design data.

[0081] Further, in some embodiments, Figure 2 ​​The step of determining the size information of the initial three-dimensional scene according to the actual distance parameter value in step S205 in the embodiment can include: determining a virtual metric distance on each coordinate axis in the spatial coordinate system according to the actual distance parameter value; and determining the size information of the initial three-dimensional scene according to the virtual metric distance on each coordinate axis.

[0082] The sensing device can be a light sensor, a camera with a light sensor, or the like. In this embodiment, the ranging and calculation of the scene can be completed by the laser sensor and the camera to obtain accurate scene size values, and then the three-dimensional scene can be built. Alternatively, when there is design standard data (reference data) of the target entity scene, the measurer can manually modify the size data of the initial three-dimensional scene in the corresponding interface.

[0083] In some embodiments, the step of obtaining device construction instructions and determining a device model applied to the initial three-dimensional scene and a corresponding placement position according to the device construction instructions can include: displaying a layout interface; generating device construction instructions in response to a device construction operation performed by a user on the layout interface; and parsing the device construction instructions to obtain the device model and the corresponding placement position.

[0084] The user can first obtain a device procurement plan, and then determine the device information to be displayed in the current scene construction based on the device procurement plan. The device information can include device type, device model, device shape, and the like. The user can be shown a layout interface through an application program on a mobile device, and the user can perform selection or dragging operations on the displayed layout interface to generate device construction instructions, and then the mobile device parses the instructions to determine the device model specified by the user and the placement position of the device model. Specifically, the user can first obtain the requirements of an IDC (Internet Data Center) procurement plan, and determine the devices such as cabinets, bridges, cages, precision air conditioners, and cameras that need to be installed in the plan. The user can then complete the placement of the device model in the AR scene by dragging the device model from the device library provided by the app through the app on the mobile phone.

[0085] Figure 8 A flowchart of a method for constructing a three-dimensional scene according to an embodiment of the present disclosure is shown in FIG. 8. Figure 8 As shown in FIG. 8, Figure 2 The step of displaying the device model in the initial three-dimensional scene according to the placement position in step S209 in the embodiment can further include the following steps:

[0086] In step S801, the actual model size of the device model is obtained, and the display size of the device model is obtained based on the size information of the initial three-dimensional scene and the actual model size.

[0087] Step S803, placing the device model with the display size in the initial three-dimensional scene according to the placement position through the augmented reality AR technology.

[0088] Step S805, adjusting the coordinates and / or direction of the device model placement using a nonlinear fitting algorithm to determine the target placement position of the device model placement.

[0089] Step S807, displaying the device model with the display size in the initial three-dimensional scene based on the target placement position through the virtual reality VR technology.

[0090] In some practical applications, after the user selects the device model in the mobile phone app for placement, the user can also perform editing operations on the properties of the device model such as position, size, angle, transparency, and note information. After the device models are placed one by one, a target three-dimensional scene that meets the user's procurement scheme requirements can be generated, and the target three-dimensional scene can be displayed to the user.

[0091] Figure 9 A schematic diagram of displaying a device model in a three-dimensional scene in a three-dimensional scene construction method of one embodiment of the present disclosure is shown, as shown in Figure 9 As shown, it includes an initial three-dimensional scene 900 and a device model 901 placed in the initial three-dimensional scene 900. The schematic Figure 9 A scene effect containing a device model is displayed.

[0092] Figure 10 A flowchart of a three-dimensional scene construction method of one embodiment of the present disclosure is shown, as shown in Figure 10 As shown, it includes:

[0093] Step 1: First, use the mobile phone app to open the camera function in the mobile phone, and display the camera shooting content in real time in the application; 360-degree shooting can be completed by holding the mobile phone, and the image information of the room (i.e., the target entity scene) is analyzed by shooting, and the sensor information obtained by the accelerometer and gyroscope is used to calculate and initialize the X, Y, and Z coordinate axis information of the scene.

[0094] Step 2: After the coordinate axes of the scene are established, feature point recognition in the room image can be performed to complete surface recognition and recording in the scene / room, for example, four wall surfaces (or multiple wall surfaces), one floor surface, one ceiling surface, and a number of surfaces can be clearly distinguished. On this basis, the boundary of the room is labeled, and a virtual three-dimensional scene is preliminarily created.

[0095] Step 3: In the virtual scene of the previous step, a number of surface information has been recorded and identified. A semi-transparent mesh can be created in the virtual scene through the mobile app to mark the surface; if the equipment has been placed in the room, the surface of the cabinet and equipment can be ignored at this time, and the patch operation will not be performed on these surfaces. After the patch operation and surface marking are completed, the application on the mobile phone (such as the application can provide Ceres library) can be used to realize the splicing of the surface through nonlinear fitting, and the virtual surface conforming to the actual scene is generated to improve the accuracy of the three-dimensional virtual scene created in step two.

[0096] Step 4: The mobile LIDAR is called through the mobile app to complete the measurement and calculation of the distance (size) of each surface in the scene. The measured and calculated values can be used to generate coordinate axes X', Y', and Z'. After saving the values of X', Y', and Z' to the local storage of the mobile phone, these relatively accurate scene size values can be used as input data and transmitted to the system background through the network interface to complete the virtual three-dimensional scene building. In addition, if there is one or more design standard data (reference data) of the machine room, the measurer can manually modify the size data of the machine room scene in the mobile app interactive interface.

[0097] Through steps 1-4, the creation of a specified IDC machine room virtual three-dimensional scene can be quickly completed using the mobile app.

[0098] Step 5: The equipment such as cabinets, bridges, cages, precision air conditioners, and cameras that need to be installed in the scheme can be determined according to the customer's IDC procurement scheme requirements. The customer can be a mobile app user, and the customer can place the three-dimensional device model in the AR scene by dragging from the device library of the app. After selecting the device model, the customer can also edit the position, size, angle, transparency, and note information of the device model. After the devices are placed one by one, the target three-dimensional scene that meets the customer's procurement scheme requirements can be generated in the mobile app, and the target three-dimensional scene can be demonstrated or shown to the customer as a construction scheme layout.

[0099] Step 6: The virtual machine room procurement construction scheme layout obtained in step 5 can be further optimized, such as further optimizing the placement position and angle of the equipment. In this step, the mobile app can be used to complete the optimization of the placement position and angle of the virtual equipment in the AR scene through a nonlinear fitting algorithm to obtain the optimized virtual equipment placement position values.

[0100] Step 7: Based on the data generated in Step 6 and the virtual scene generated in Step 4, a more accurate construction plan layout can be generated. This construction plan layout is not limited to display in an AR environment. In some practical applications, this construction plan layout can also provide a basic data model for precise engineering management applications. It can be used as a digital twin construction plan model for use by IDC data center sellers, customers, construction companies, supervisors, and other parties.

[0101] The three-dimensional scene construction method provided in this disclosure can achieve the following functions and effects: 1) It can build a virtual three-dimensional scene of a real IDC data center using devices such as mobile phone cameras and sensors, combined with image recognition and nonlinear fitting methods; 2) It can use AR technology to place virtual devices in the three-dimensional scene, and through data fitting, complete a display example of a construction plan (i.e., the target three-dimensional scene) with relatively accurate size and position. After the construction plan is saved, it can be displayed in the three-dimensional virtual scene via VR, rather than being limited to displaying it via AR based on the real scene.

[0109] In some embodiments, the placing module 1104 acquires the device construction instruction, and determines the device model applied to the initial three-dimensional scene and the corresponding placement position according to the device construction instruction, including: displaying a layout interface; generating the device construction instruction in response to a device construction operation performed by a user on the layout interface; and parsing the device construction instruction to obtain the device model and the corresponding placement position.
