It should be noted that, the BIM model is rendered in a two-dimensional view angle, as shown in fig. 6 and 7, the view angle is a view angle displayed to a user, and a plane of the view angle is equivalent to a video picture, so that when it is determined that the BIM model is rendered in the two-dimensional view angle by establishing a two-dimensional rectangular coordinate system according to the resolution of the video picture, an x coordinate and a y coordinate of each component in a video resolution coordinate system are used as position information of the component, and a display size of the component is determined by a coordinate point of the component in the video resolution coordinate system, and then a component ID is determined according to a component requiring additive networking data, so as to extract a component ID, a component coordinate position and a component display size of the component for fusion display from a component rendering result of adding the networking data as required.
In some embodiments, the part information includes a part ID, a part coordinate position, and a part display size of each part in the BIM model.

In the video stream of the present application, an MPEG-2 standard ts (transport stream) encapsulation format is taken as an example, and the component ID, the component coordinate position, and the component display size are increased based on the encapsulation format.
Among them, the MPEG-2 standard TS format package is divided into an ES stream, a PES stream, and a TS stream. Fig. 3 is a schematic diagram showing the relationship among the ES stream, the PES stream, and the TS stream.
The ES Stream (Elementary Stream) is composed of three parts, namely, an image data Stream encoded by an MPEG-2 video encoder, a sound data Stream encoded by an MPEG-2 video encoder, and other encoded data streams.
A PES Stream (Packetized Elementary Stream) is a data Stream formed by processing an ES Stream by a PES packetizer, and in this process, operations such as packetizing, adding header information to the ES Stream are completed, and usually I, P, B is a complete frame, which is a PES packet.
The TS stream is composed of TS packets with fixed length, the length of each TS packet is 188 bytes, the TS packets are re-packed into one PES packet, and the packet header information of the PES packet still exists in the TS packets.
As shown in fig. 4, the TS Packet structure is schematically illustrated, wherein the TS Packet is divided into a Packet Head and a Packet Data, a PID field in the Packet Head is a unique identifier in the TS stream, and the content of the Packet Data is determined by the PID.
When PID is 0, Packet Data is referred to as PAT Table (Program Association Table) and PID number of PMT Table (Program Map Table) corresponding to video content number.
When the value of the PID is the PID number corresponding to a certain PMT table, it indicates that Packet Data is the PMT table corresponding to a certain content serial number, and is used for indicating the PID number corresponding to the video, audio and Data TS related to the content.
Specifically, as shown in fig. 5, a PAT table and a PMT table are schematic diagrams.
Wherein the TS packet shown in fig. 4 is a newly added TS packet containing the component information, and then the related information is added to the PMT table shown in fig. 5 to realize embedding the component information in the video stream.
As shown in fig. 4, the component ID contained in one frame in the video content, the component coordinate positions, i.e., position x and position y, and the component display size are contained in Packet Data of a TS Packet containing component information.
Where multiple building blocks may be included in a frame, multiple TS packets may be required for presentation.
In some embodiments, the displaying, by the user end, the BIM model video stream embedded with the component information after being fused with the internet of things data includes:
and the user side fuses the BIM model video stream embedded with the component information and the data of the Internet of things through a screen menu type OSD (on screen display) and displays the video stream.
It should be noted that, the video stream is encoded when the video stream is transmitted, and the video stream is correspondingly decoded after the video stream is received at the user terminal.
It should be further noted that On Screen Display (OSD) is applied to a CRT/LCD Display, and some special characters or graphics are generated in the Screen of the Display, so that the user can obtain some information Display modes. It is commonly found on the display screen of a household tv or a PC, and when a user operates the tv to change channels or adjust the volume and image quality, a predetermined position on the tv screen displays some special characters and graphics. The BIM video stream embedded with the building block information is subjected to fusion display by utilizing the characteristic.
In the application, the user side displays real-time data acquired by the data of the internet of things to the corresponding position of the corresponding component according to the ID, the coordinate and the size of the component information, and fusion display of the data of the internet of things and the BIM is achieved.
As shown in fig. 6, which is a schematic view of a fusion display effect of internet of things data and a BIM model in another embodiment of the present application, it can be seen from fig. 6 that the internet of things data is displayed at a corresponding position above a corresponding component, and the position and the size of the internet of things data displayed by the OSD technology are displayed according to a preset relative position and a preset display mode based on the position x coordinate and the position y coordinate of the component in a video resolution coordinate system and the size of the component, that is, the display position of the internet of things data is in the same video resolution coordinate system as the component, and in fig. 6, for example, the internet of things data is displayed above the corresponding component by an indication line. Other display modes can be selected, and the corresponding relation between the data of the internet of things and the member can be marked.
It should be further noted that, in the present application, the whole process from receiving the user instruction to rendering the BIM model to generate the video stream to fusing and displaying the internet of things data and the BIM model to the user through the OSD technology is performed in real time, the user may send a control instruction in a manner of, for example, zooming by a roller, pressing a left key to rotate the model, and the displayed model and the internet of things data displayed in the model may be changed accordingly.
For example, if the user sends a command for model reduction through the wheel, taking the internet of things data "water works" in fig. 6 as an example, the server generates a rendering command after receiving the user command, performs a corresponding real-time BIM model rendering work, and at the same time, component information in the model changes accordingly due to the reduction of the model, for example, a component corresponding to the water works in the model will be reduced, the size of the component will change, i.e., reduced, and at the same time, the coordinates of the component in the video resolution coordinate system will change, i.e., the position of the component will change, so that new component information is embedded in the video stream and sent to the client, and the position and size of the internet of things data display implemented by the OSD technology are displayed according to a preset relative position and display manner based on the position x coordinate and the position y coordinate of the component in the video resolution coordinate system and the size of the component, when the position and the size of the component are reduced, the synchronous Internet of things data 'water works' corresponding to the component are correspondingly changed in position and size, and then OSD fusion display is carried out according to a preset display mode, wherein the component ID is not changed, so that the name 'water works' confirmed according to the component ID is not changed. Therefore, the process of fusing the display models in real time according to the user instruction is completed.
As shown in fig. 7, a schematic diagram of a fusion display effect of the internet of things data and the BIM model after being reduced is shown.
In summary, the embodiment of the present application provides a fusion display method based on internet of things data and a BIM model, including: the server receives a request instruction sent by a user side, wherein the request instruction comprises a BIM (building information modeling) model requested by the user; rendering the BIM requested by the user to obtain a rendering result; obtaining component information corresponding to all components to be added with the data of the Internet of things in the BIM according to the rendering result; generating a BIM model video stream according to the rendering result; embedding the building block information in the BIM model video stream; sending the BIM video stream embedded with the component information to a user side; the user side acquires Internet of things data corresponding to the component information from the Internet of things; and fusing the BIM video stream embedded with the component information with the Internet of things data and then displaying the fused BIM video stream.
