The objects are classified into 4 types, namely outdoor park-3.3, street-3.4, building-3.2 and tunnel; a building or tunnel may have multiple floors and be represented by a cube. Parks or streets are represented by the ground. The zone boundaries, whether cubic or planar, are generated from the minimum and maximum values of the latitude and longitude, and the minimum and maximum values of the floors, as appropriate. Without explicit dimensions, the floor appears to be 4 meters high. Each sensor element (3.1) is centered on the longitude and latitude and is perpendicular to 2 meters above the floor level contained.
The limitation of automatically generating geometry is that the rendered geometry is greater than or equal to the actual physical boundary. This can be improved if there are area marker sources, such as 2D map databases. It should be noted that the elements are drawn and not labeled. The model is thought to be a basic concept of a thematic 3D map, the model can be rendered and animated according to a query result, the 3D model is manufactured by a drawing method, and the 3D model with a blank area can be effectively created.
It should also be noted that the presentation of such a graphical interface is highly compatible with city planning, allowing 3D models to be created without 2D or 3D map data at all, and that the graphical interface will also automatically generate 2D map models from the underlying object geometry. In other words, given a space in an existing map representing future developments, the method provided by embodiments of the present invention will fill the space.
It should be noted that, in the embodiment of the present invention, a cabinet model is introduced to store information, for example, referring to fig. 3, a graphical interface topology may be derived from an underlying cabinet structure in the data cloud CDN. Line 13 defines the camera, line 9 defines the sector containing the map, and line 8 defines the area containing the map.
For camera information (line 13), column K defines the camera as park (green) class, column L defines the camera as GPU face class, column G indicates that the camera is on level 1, so the center elevation is 2 meters, and column I, J defines latitude and longitude.
The green class indicates that a ground plane needs to be generated. Column CDE defines an area, sector and region for the camera. The area boundary of all cameras sharing the same area in longitude and latitude is the three-dimensional model ground plane. The boundaries of the sector are the maximum and minimum values of the sector area. The boundary of a region is the maximum and minimum of all sectors in the region.
By utilizing the cabinet model, the longitude and latitude, height, image, video and other information of each Internet of things device can be effectively stored, real-time calling can be realized, and further, in the method provided by the embodiment of the invention, the characteristic information can be quickly and accurately acquired from the cabinet model so as to smoothly finish the drawing of the 3D model. Please see the following table: the following table is an information list stored in the data cloud by a certain internet of things device.
| Device information | Means of | Device information | Means of | |
| Opt＝cam | The device being a camera | Zone＝1 | Zone code number | |
| Reg＝30 | Code number of area | Floor＝1 | First layer | |
| Sect＝1 | Sector code number | Cam＝1 | Camera code | |
| Area＝1 | Location of area | Lat＝34.2540882 | Longitude (G) | |
| C1＝g | Park (Green) class | Lng＝108.9423662 | Latitude | |
| C2＝face | GPU face class |
As can be seen from the above table, the Internet of things equipment is defined as a park (green) class and a GPU face class, and is located at the 1 st floor, and the center elevation is 2 m. The green class indicates that a ground plane needs to be generated. The area boundary of all cameras sharing the same area in longitude and latitude is the three-dimensional model ground plane.

making and generating a user interface, wherein the user interface comprises a left window, a middle window and a right window; the left window displays the 2D map, the right window displays the 3D model, and the middle window manages query operation and displays query results.
Specifically, in the embodiment of the invention, the 3D model can be drawn by using the internet of things device in the target area, and after the 3D model is drawn, the system automatically generates the 2D map model from the bottom layer object geometric figure. In the user interface, above the three panels (3.3, 3.4, 3.5) there is a top bar (3.1, 3.2) of 3 parts, which displays a 2D map in the left panel, a library of thumbnails etc. query information in the middle pane, and a 3D model in the right pane. The main navigation is 2D, and the map can be translated. Clicking on the map sector or area icon will correctly position the 3D model. The rendered rendering of the two-dimensional map and the three-dimensional model will be based on the query results, which the center panel manages.

In an embodiment of the present invention, please refer to fig. 9, which provides a 3D image user interface, and this figure describes the cloud data center server as one of the building of the GUI model in detail. The disks are represented above ground, the CPUs and GPUs are represented below ground, and the network is represented above ground. Servers (8.1) in the data cloud topology are associated with the region but not with the sector, so the servers within the region will appear as a single model. Disk icon (8.4), GPU/GPU icon may be colored (8.5) to indicate fault status and performance aspects. Network traffic between different servers and from clients will appear as an automated pipe, similar to a building's HVAC presentation.
It should be noted that, referring to fig. 5, in the embodiment of the present invention, a gallery expander is further added, and the gallery expander provides a thumbnail-based navigation mechanism. The top toolbar icon (4.1) toggles this view, which will expand the thumbnail library to cover the 3D model portion. The user is allowed to navigate through the thumbnails rather than the default map-by-map navigation. And clicking the thumbnail to directly jump to an access record of the face.
Referring to fig. 8, in an embodiment of the present invention, a clock tool is added that allows the time scale to be changed from the default value "current" (within 10 minutes) to a defined interval.
