In the following illustration, the server cluster 101 is exemplified as an execution subject.

As shown in fig. 2, the three-dimensional scene construction method provided by the embodiment of the present disclosure may include the following steps:

In step S201, scene image data of the 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.

In this embodiment, the target entity scene may be a specific machine room, a server storage room, a working space, and the like. The scene image data may be multimedia files in the form of videos, motion pictures, image sets, etc.; the scene image data can be obtained by image acquisition of the target entity scene by using image acquisition equipment with a sensing device, for example, the scene can be shot by using a camera of a mobile phone to obtain video, a moving picture, an image set and the like of the target entity scene.

In step S203, surface objects in the scene image data are identified, and an initial three-dimensional scene of the target entity scene is constructed in a spatial coordinate system based on the surface objects. Wherein the surface object may be a wall, a ceiling, etc. in the target physical scene. The initial three-dimensional scene may be a virtual-scene-rendered representation of a target physical scene without device decoration, such as: the initial three-dimensional scene may be a virtual scene consisting of four walls, a top surface, and a bottom surface.

Step S205, obtaining the actual distance parameter value in the target entity scene, and determining the size information of the initial three-dimensional scene according to the actual distance parameter value. The actual distance parameter value may be information actually describing the size of the target physical scene, such as size information of each wall surface, height information in the scene, and the like.

Step S207, acquiring a device construction instruction, and determining a device model and a corresponding placement position applied to the initial three-dimensional scene according to the device construction instruction. The device building instruction may be issued by the user in a corresponding operation interface displayed on the client 103; the device build instructions may indicate the type or style of device that the user wishes to pose, and may indicate the location in the initial three-dimensional scene where the user wishes to pose the device model.

Step S209, the equipment model is displayed in the initial three-dimensional scene according to the placement positions, and further a three-dimensional scene with the equipment construction effect is generated. In this embodiment, the device model specified by the user can be quickly placed in the constructed initial three-dimensional scene in a visualized manner 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 displayed.

By the three-dimensional scene construction method provided by the embodiment of the disclosure, an initial three-dimensional model of a target entity scene can be constructed, and the equipment model can be displayed in the initial three-dimensional model in quick response to the equipment construction instruction of a user, so that corresponding scene effects are generated and displayed. The method has the advantages of short construction period, easy modification and capability of flexibly and rapidly responding to the demands of clients to display scenes.

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

The scene image data may have sensing information, such as: using the accelerometer, the gyroscope obtains sensory information. For another example, the relative position of the image in the scene image data can be identified by the mobile phone camera and the sensor, and further the X, Y, Z triaxial for the initial three-dimensional scene is marked.

Fig. 3 is a schematic diagram of generating a spatial coordinate system in a three-dimensional scene construction method according to an embodiment of the present disclosure, and fig. 3 is a schematic diagram of generating a spatial coordinate system with three-dimensional directions in a scene image, where the three-dimensional directions include: x-axis, Y-axis, Z-axis.

Fig. 4 shows a flowchart of constructing an initial three-dimensional scene in the three-dimensional scene constructing method according to an embodiment of the present disclosure, and as shown in fig. 4, step S203 in the embodiment of fig. 2 may further include the steps of:

In step S401, feature points on each image in the scene image data are determined by the augmented reality AR technology, and a surface object in the scene image data is identified according to the feature points. Among these, the surface objects may be, for example, 4 walls (or walls), 1 floor, 1 ceiling, and several surfaces.

Step S403, determining a position of the surface object in the spatial coordinate system based on the spatial coordinate system corresponding to the scene image data.

Step S405, constructing an initial surface model of the surface object according to the position of the surface object in the spatial coordinate system. Through step S405, the position of the surface object in the space coordinate system may be determined based on the generated space coordinate system, so as to complete the boundary labeling of the target entity scene, and further create the initial surface model of the surface object.

Step S407, optimizing the initial surface model through a nonlinear fitting technology to obtain a target surface model, and constructing an initial three-dimensional scene of the target entity scene according to the target surface model.

It can be seen that by implementing fig. 4, the surface recognition and recording in the target entity scene can be completed through the feature point recognition in the scene image, creating a virtual initial three-dimensional scene. Specifically, through the AR mode, equipment such as a mobile phone camera and a sensor is used, and methods such as image recognition and nonlinear fitting are combined, so that the space recognition of an actual IDC machine room is realized, and the establishment of the initial three-dimensional scene is further completed.

Fig. 5 shows a flowchart of obtaining a target surface model in the three-dimensional scene construction method according to an embodiment of the present disclosure, and as shown in fig. 5, step S407 in the embodiment of fig. 4 may further include the following steps:

in step S501, mesh objects corresponding to an initial surface model are created in an initial three-dimensional scene. In some implementations, a translucent mesh may be created in an initial three-dimensional scene by an application in a mobile device (e.g., a cell phone).

Step S503, attaching the mesh object to the corresponding initial surface model, and generating labeling information of the initial surface model. In some practical applications, the created semitransparent net sheet can be attached to the ground or the wall surface through the related application program so as to realize the surface marking.

And step S505, splicing the initial surface model based on the labeling information by a nonlinear fitting technology to obtain the target surface model. The stitching of the faces may be accomplished using non-linear fitting functions provided in the relevant applications described above (e.g., using functions provided by Ceres libraries in the applications) to generate virtual faces that more closely conform to the actual scene as the target surface model.

Therefore, by implementing fig. 5, the semitransparent net piece can be created to be attached to the ground or the wall surface in the initial three-dimensional scene, and the nonlinear fitting and the surface splicing are completed, so that the effect of improving the accuracy of identifying and marking each surface in the initial three-dimensional scene is achieved.

By implementing the schematic diagram shown in fig. 7, the initial three-dimensional scene and the mesh object 703 may be displayed through an operation interface 701 provided by an application program in the mobile device 700 (such as a mobile phone), and an operation button 702 for labeling may be provided in the operation interface 701, so that a user may perform corresponding operation on the operation button 702, thereby labeling the mesh object 703. Further, in the present schematic diagram, the operation buttons 702 may include labeling operation buttons for the wall surface, the ground surface, and the invalid surface, as shown in fig. 7, the labeling operation button for "wall surface" may be pressed to slide toward the mesh object 703, and at this time, a prompt message for "dragging the label as the wall surface" may appear in the operation interface 701.

In some practical applications, if there are devices (such as a cabinet, a computer desk, etc.) or decoration facilities already existing in the target entity scene, the surfaces of the devices (such as the cabinet, the computer desk, etc.) or the decoration facilities may be ignored first in the process of labeling the initial surface model, the mesh objects are not created on the surfaces, and the labeling operation is not performed on the surfaces.

In some embodiments, the step of obtaining the actual distance parameter value in the target entity scene in step S205 in the embodiment of fig. 2 includes: using image acquisition equipment with a sensing device to measure the distance of a target entity scene to obtain an actual distance parameter value in the target entity scene; and/or acquiring building design data of the target entity scene, and determining actual distance parameter values in the target entity scene according to the building design data.

In this embodiment, the distance measurement and calculation of the scene can be completed through the laser sensor and the camera, so as to obtain an accurate scene size value, and further complete the construction of the three-dimensional scene. Alternatively, when there is design standard data (reference data) of the target entity scene, the measurer may be allowed to manually modify the size data of the initial three-dimensional scene in the corresponding interface.

In some embodiments, the step of obtaining device build instructions, determining a device model and corresponding pose location applied to the initial three-dimensional scene from the device build instructions may include: displaying a layout interface; responding to equipment construction operation performed by a user on a layout interface, and generating equipment construction instructions; and analyzing the equipment construction instruction to obtain an equipment model and a corresponding placement position.

The layout interface can be displayed to the user through an application program on the mobile device, so that the user can select or drag the layout interface to generate a device construction instruction, and further the mobile device analyzes the instruction to determine a device model designated by the user and the placement position of the device model. Specifically, a user can acquire the requirement of an IDC (Internet Data Center, network data center) purchasing scheme, determine equipment such as a cabinet, a bridge, a cage, a precision air conditioner, a camera and the like which need to be installed in the scheme, and finish the placement of an equipment model in an AR scene in a dragging mode from an equipment library provided by the app through a mobile phone app.

After the equipment models are placed one by one, a target three-dimensional scene meeting the requirement of a user purchase scheme can be generated, and the target three-dimensional scene is displayed to the user.

Step 3: several surface information has been recorded and identified in the virtual scene of the previous step. A semitransparent net piece can be created in the virtual scene through the mobile phone app and attached to the ground or the wall surface so as to carry out surface marking; if the room has equipment already in place, the surfaces of the cabinet and the equipment can be optionally ignored and no more surface-mounting operations can be performed on these surfaces. After the surface labeling is completed, the surface can be spliced by using an application (such as an application capable of providing Ceres library) on the mobile phone through nonlinear fitting, and a virtual surface conforming to the actual scene is generated, so that the accuracy of the three-dimensional virtual scene created in the step two is improved.

Step 4: the mobile phone app invokes the mobile phone LIDAR to finish measurement and calculation of each surface distance (size) in the scene, the measured and calculated values can be used for generating coordinate axes X ', Y', Z ', the values of X', Y ', Z' are stored in the mobile phone for local storage, and the relatively accurate scene size values can be used as input data and transmitted to a system background through a network interface to finish virtual three-dimensional scene construction. In addition, if one or more machine room design standard data (reference data) are provided, the measurer can be allowed to manually modify the size data of the machine room scene in the mobile phone app interactive interface.

Through the steps 1-4, the creation work of the virtual three-dimensional scene of the specified IDC machine room can be completed quickly by using the mobile phone app.

Step 5: the equipment such as a cabinet, a bridge, a cage, a precise air conditioner, a camera and the like which are required to be installed in the scheme can be determined according to the requirements of the IDC purchase scheme of the client, the client can be a mobile phone app user, and the client finishes the placement of the three-dimensional equipment model in an AR scene in a dragging mode from the equipment library of the app by using the mobile phone app. After the customer selects the equipment model, the customer can edit the position, size, angle, transparency, remark information and other properties of the equipment model. After the equipment is placed one by one, a target three-dimensional scene meeting the requirement of a customer purchasing scheme can be generated in the mobile phone app, and the target three-dimensional scene can be used as a construction scheme layout to be demonstrated or displayed for the customer.

Step 6: the virtual machine room purchasing construction scheme layout obtained in the step 5 can be further optimized, for example, the placement position and the placement angle of the equipment can be further optimized. In this step, the mobile phone app can be used to optimize the placement position and angle of the virtual device in the AR scene through a nonlinear fitting algorithm, so as to obtain the optimized placement position value of the virtual device.

Step 7: the more accurate construction scheme layout can be generated according to the data generated in the step 6 and the virtual scene generated in the step 4. The construction scheme layout can be displayed in an AR environment without limitation, and in some practical applications, the construction scheme layout can also provide a basic data model for accurate engineering management application, and can be used as a digital twin construction scheme model for multiple parties such as an IDC machine room seller, a client, a constructor, a supervisor and the like.
