The embodiment of the application can be used in scenes such as smart cities and smart parks.
In order to facilitate understanding of the embodiments of the present application, the following specifically describes the scheme proposed in the embodiments of the present application by taking the flowchart shown in fig. 1 as an example.
In a possible manner, the flowchart shown in fig. 1 may be implemented by a terminal device, or may be implemented by a single system, which is used to unify the three-dimensional model of the building and perform the association binding with the room information in the room database. The singulation system may include a terminal device and at least one server. Specifically, the room information may be maintained in advance and stored in a room database of the single-system. The terminal Device related to the present application is a terminal Device with a display screen, and may be a Mobile Phone (Mobile Phone), a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable Device, and so on. The wearable device may include, for example, a smart watch or smart glasses, a smart bracelet, and the like.
101, a three-dimensional model of a building is obtained.
The three-dimensional model of the building can be made by professional software in advance and stored in the single-body system or the terminal equipment. For example, a three-dimensional model of a building may be created using professional software such as 3D MAX (3D Studio MAX) software and Computer Aided Design (CAD) software.
The three-dimensional model of the building can be stored in the terminal device in advance, or the terminal device acquires the three-dimensional model of the building from the server.
And 102, picking up the floor elevation and the roof elevation of the unit building to be singulated in the three-dimensional model.
The terminal equipment can obtain the floor elevation and the roof elevation of the unit building to be individualized from the server. The address of the unit building, such as the gold water source 12 # building 3 unit, can be input.
And the floor elevation and the roof elevation of the unit building to be individualized are used for representing the altitude of the lowest point and the highest point of the unit building. The floor elevation and the roof elevation may be pre-stored in the home database. Referring to the position of the upper left corner in the display interface of the terminal equipment shown in fig. 2, the floor elevation and the roof elevation of the picked unit building to be singulated are displayed. Alternatively, the picked-up ceiling elevation and floor elevation may adopt the elevation height under wgs-84 geographic coordinate system, the wgs-84 geographic coordinate system is an internationally adopted geocentric coordinate system, the origin of coordinates is the centroid of the earth, the Z-axis of the geocentric space rectangular coordinate system points to the direction of protocol earth polar (CTP) defined by the International time service organization (Bureau International de l' heart, BIH), the X-axis points to the intersection point of the meridian plane zero and the CTP of the BIH, and the Y-axis is perpendicular to the Z-axis and the X-axis to form a right-hand coordinate system, which is called a world geodetic coordinate system.
And 103, determining the plane position of the unit building to be individualized in the three-dimensional model.
The terminal equipment detects the marking operation of a user on a display interface and acquires four marking points for describing the plane position; wherein the display interface is as shown in fig. 2 for displaying a three-dimensional model of the building. It is to be understood that the quadrangle formed by the four marked points can enclose one apartment of the unit building to be singulated. Optionally, the four marked points for describing the plane position may be described by latitude and longitude under the geographic coordinate system of wgs-84, for example:
[Pws,Pes,Pen,Pwn]；
pws is a southwest orientation plane marking point;
the Pes is a southeast orientation plane mark point;
pen is a marker point of the northeast azimuth plane;
pwn is a marker point of the northwest azimuth plane.
When the flow of fig. 1 is implemented by a terminal device, step 103 is performed by the terminal device. When the process of fig. 1 is implemented by a single unified system, step 103 may be obtained by the terminal device and sent to the server.
And 104, generating cuboid blocks respectively corresponding to the N floors of rooms with the same plane position according to the floor elevation and the roof elevation.
When the flow of fig. 1 is implemented by a terminal device, step 104 is performed by the terminal device. When the process of fig. 1 is implemented by a single unified system, step 104 may be executed by the server and sent to the terminal device. Further, the terminal device displays the cuboid blocks on the display interface.
The floor heights of the N layers of rooms are the same, the plane positions of the N layers of rooms are the same, and the cuboid blocks corresponding to each layer of room comprise the space positions of each layer of room in the three-dimensional model.
It should be understood that, according to the characteristics of the residential building, in most cases, the flat type of the rooms on different floors in the same plane position of the same unit building is consistent, so that after the flat position of one room is determined, other rooms on different floors can be reused. In addition, the floor spacing is also kept consistent in most cases, and batch construction is also possible.
Specifically, the floor height of the unit building and the floor number of the unit building are firstly obtained from the family room database; and dividing the unit building into N cuboid blocks according to the floor average according to the plane position, the floor elevation, the roof elevation, the floor height and the floor number of the unit building. For example, the family database contains family information, cell names, building numbers, unit building numbers, and the like. The information of the apartment may include identity information of the resident, such as name, sex, age, physical condition, identification number, etc.
As an example, as shown in fig. 3, a rectangular parallelepiped block of a unit building to be singulated, which includes a spatial position of the unit building to be singulated, may be determined according to a ceiling elevation and a floor elevation and a plane position of the unit building to be singulated. And further averagely cutting the cuboid blocks of the unit building to be individualized according to the floor height and the floor number of the unit building to be individualized in the apartment database to obtain N cuboid blocks corresponding to N floors of apartment of the unit building to be individualized. For example, the units to be singulated are a-cell No. 8 building 1 unit 101-N01 rooms (N represents the number of floors of the highest floor of the a-cell No. 8 building 1 unit), and the cuboid blocks including the a-cell No. 8 building 1 unit 101-N01 rooms are cut according to the floor height and the number of floors to obtain N cuboid blocks corresponding to N floors of the apartment, and each cuboid block of the N cuboid blocks can surround the spatial range of the apartment corresponding to the floor.
And 105, storing the cuboid block data respectively corresponding to the N layers of the rooms and the room information for representing the N layers of the rooms in a one-to-one correspondence manner in a room database, wherein the cuboid block data corresponding to each layer of the room is used for describing the cuboid blocks respectively corresponding to each layer of the room.
In the first aspect, the terminal device associates N cuboids corresponding to N levels of user rooms with user room information of N levels of user rooms in the user room database in response to an association operation of a user on a display interface. Next, the first room of the N-level rooms is described as an example. Storing a first room in the N layers of rooms and room information used for representing the first room in a room database in a related manner; the first user room is any one of the N layers of user rooms, the display interface displays the first cuboid block identifier and the first user room identifier, the first cuboid block identifier is used for identifying a cuboid block of the first user room, the cuboid block data of the first user room comprises the first cuboid block identifier, the first user room identifier is used for identifying the first user room, the user room information of the first user room comprises the first user room identifier, and the association operation is directed at association of the first cuboid block identifier and the first user room identifier.
The cuboid block data of the first room may comprise one or more of a first cuboid block identification, a planar position of the cuboid block of the first room, a bottom surface height of the cuboid block of the first room, or a top surface height of the cuboid block of the first room, etc.
A first cuboid block identifier for characterizing a number of layers of the first cuboid block;
the plane position of the cuboid block of the first household room is used for representing a plane range covered by a quadrangle formed by plane marking points of the cuboid block of the first household room in four directions of southwest, southeast, northeast and northwest;
the bottom surface height of the cuboid block of the first household room is used for representing the bottom surface elevation of the cuboid block of the first household room in a three-dimensional space, the elevation refers to the distance from a certain point to an absolute base surface along the direction of a plumb line, and the absolute base surface is a leveling base surface with the average seawater plane elevation of a certain seashore place fixed as zero;
the top surface height of the cuboid block of the first room is used for representing the top surface elevation of the cuboid block of the first room in three-dimensional space.
In one possible implementation, as shown in fig. 4, the association between the cuboid data of the first user room and the user room information of the first user room may be performed in a cascaded manner. When two objects are in cascade relation, and when any object is modified, deleted and the like, the other object can be synchronously executed with the same operation. In the embodiment of the present application, when the cuboid data of the first room and the room information of the first room are in the cascade relationship, the room information of the first room is modified, and then the cuboid data of the first room is modified in the same way, and repeated modification operations do not need to be manually performed.
On the other hand, after the first room cuboid data and the room information of the first room are correlated, the first room cuboid data is stored in the room database in the WKT format, and the WKT format is a text mark format.
Next, for example, the four marked points used for representing the plane position in the cuboid data of the first room in the above step 103 are: [ Pws, Pes, Pen, Pwn ];
storing in a WKT format upon storing, the WKT format being as follows:
POLYGON ((Pws [0] Pws [1], Pes [0] Pws [1], Pen [0] Pen [1], Pwn [0] Pwn [1])), wherein Pws [0] is the longitude of the southwest azimuth plane marking point, Pws [1] is the latitude of the southwest azimuth plane marking point, and the data stored in the southeast, northeast and northwest are also the longitude and latitude.

Optionally, the cutting of the cuboid block corresponding to the cuboid block data of the second user room, which is attached to the outer surface contour of the three-dimensional model, may be performed automatically by a single system. For example, the three-dimensional model may be a model in an Irregular Triangulated Network (TIN) format, and the above-mentioned clipping operation is to eliminate a redundant portion outside a polygon according to a portion that is reserved as a constraint polygon on the outer surface of the three-dimensional model in the TIN-format three-dimensional model.

In fig. 6, the unit building to be singulated is exemplified by a four-story building. Specifically, the displayed square points of the plane position are represented by longitude and latitude under a geographic coordinate system of wgs-48, and the displayed elevation of the top floor and the elevation of the bottom floor are represented by altitude under a geographic coordinate system of wgs-48. It should be noted that the numbers shown in the page 601 are only used as an example.
And 602, when the terminal device detects that the user clicks the 'generate monomer' option at the upper left corner in the display page, firstly generating rectangular blocks corresponding to four floors of rooms with the same plane position according to the floor elevation and the roof elevation. For ease of description, we will refer to the resulting cuboid blocks as monomers herein. Further, the terminal device displays a monomer list composed of the monomer identifications in the generated monomer data corresponding to the four monomers on the right side of the display page 602. The position and form of the monomer list in the display page 602 are not specifically limited in this application, and fig. 6 is only an example. The monomer data includes a monomer identification, a monomer plane position, a monomer ground height, and a monomer top height. In fig. 6, the number of layers of the generated monomer is taken as the monomer identifier, such as the first layer, the second layer, and so on shown in fig. 6. Still further, the terminal device displays the room identifier in the room information of the unit building to be individualized in the room database on the right side of the individual list in the display page 602.
After the steps are completed, the terminal device detects that the user sequentially clicks the monomer identification and the room identification in the monomer list, associates the monomer data corresponding to the monomer identification clicked by the user with the room information corresponding to the room identification, and stores the associated monomer data corresponding to the monomer identification clicked by the user in the room database. The present application is not intended to be limited to the particular form of operation described, and fig. 6 is intended as an example.
For example, when detecting that the user sequentially clicks the first layer in the cell identifier and 101 in the room identifier, the terminal device associates the generated first layer cell data with the room information of the 101 room, and stores the associated first layer cell data in the room database.
603, after detecting that the user association is successfully stored, the terminal device displays the user room identifier associated with the user unit identifier after associating and storing the successfully stored single user identifier, and displays the mark point after associating and storing the successfully stored user room identifier, where the form of the mark point is not limited in this application. See the display page 603 in detail, which is a display page after the monomer data of the four-layer family room are all stored in association.
604, when detecting that the user clicks an area of a certain room on the outer surface of the three-dimensional model of the building, for example, the user clicks the outer surface of the 301 room, the terminal device first acquires the monomer data of the 301 room from the room database, fits the monomer corresponding to the monomer data of the 301 room to the outer surface profile of the 301 room for clipping, renders the clipped monomer of the 301 room into the three-dimensional model, and highlights the outer surface of the 301 room. The rendering form of the clipped monomer in the three-dimensional model is not particularly limited in the present application, and the highlight display is only taken as an example in the present application. Further, the terminal device displays the room information of the 301 room associated with the cell data of the 301 room in the display page 604 after the rendering is completed.
