When the electronic map at the building level is drawn, in order to more accurately navigate within the same floor or between different floors within the building, the electronic map at the floor level needs to be constructed for each floor of the building. At this time, a building interior hierarchical planar map of each building may be acquired, and the second electronic map in the BIM format may be constructed from the building interior hierarchical planar map of each building.

In the present embodiment, for example, a city is divided into N administrative areas, and assuming that M buildings are shared in one of the administrative areas, each building collects geometric data information and non-geometric data information. At this time, an initial building model can be correspondingly established according to the geometric data information of each building, and then the non-geometric data information of each building is bound to the corresponding initial building model as attribute data to obtain the building model of each building.

The geometric data information comprises spatial position data of the building, three-dimensional size data and a spatial constraint relation in the building;
the non-geometric data information comprises material information, price information, engineering undertaking side, right information, construction side information and remark information of the building, and right information, service information, room number information, responsible person information and business service information of the floor.
In this embodiment, the geometric data information of the building is spatial position data of the building required for three-dimensional modeling in the BIM (i.e. geographical positioning data representing the building, and more vividly representing which specific position the building is located), three-dimensional size data (i.e. geometric data representing the length, width, height, etc. of the building), and spatial constraint relationship within the building (i.e. spatial constraint relationship between members within the building, such as corridors, living rooms, and toilets).
The non-geometric data information of the building comprises material information of the building (which materials are respectively used for each part of the building), price information (which total construction cost of the building is represented), a project undertaking side of the building (which building project of the building is accepted by anyone of the persons), right information (which property owner of the building is represented), construction side information (which specific construction unit of the building is represented) and remark information. The non-geometric information of the floor mainly corresponds to right information, business information, room number information, responsible person information, business service information and the like of each room.
The remark information is written text information for the building model, and for example, the use problem existing for the building can be recorded in the remark information. And the character information corresponding to different points obtained by comparing the building model of the building with the newly added model can also be recorded in the remark information.
In one embodiment, as shown in fig. 3, step S102 includes:
s1021, acquiring the number of internal layers of each building;

s1023, fusing the floor plane distribution maps of each building according to the floor sequence to obtain a BIM electronic map of the building;
and S1024, fusing the BIM electronic maps of the buildings to obtain a second electronic map in the BIM format.
Specifically, when building a floor plan distribution map corresponding to each floor in the internal floors of the building, a BIM model is quickly built for each floor of the building according to a construction drawing or an actual building, and the BIM model is refined to each room of each floor for modeling.
And when the floor plane distribution map corresponding to each floor is obtained, naming and mapping the rooms included in the floor plane distribution map of each floor one by one so as to realize accurate identification of each room of the current floor. For example, in a room corresponding to the office on floor number XXX1, floor number XXX1, floor number 1 office, is named, and an office area icon is pasted within the display area of the room. Through the naming and mapping operations, the indoor floor level distribution graph can be accurately constructed.

s1032, correspondingly fusing the BIM electronic map of each building in the second electronic map into the building of the first electronic map to obtain a fused map.
In this embodiment, after the second electronic map corresponding to each building is constructed, the second electronic map of the building may be correspondingly bound to the GIS model of the first electronic map having the same geographical location range information as the building according to the geographical location range information of the second electronic map. For example, a city is divided into N administrative areas, and if M buildings are shared in one administrative area, wherein one building has 5 floors, when a BIM electronic map of each of the 5 floors of the building is obtained, the 5 BIM electronic maps can be correspondingly bound to a first electronic map corresponding to the building, so that when a user selects one floor of the building, a BIM electronic map corresponding to the floor of the multiple BIM electronic maps bound correspondingly in the first electronic map of the building can be called and displayed.

In this embodiment, after the fusion map is constructed, the user can not only realize route planning navigation between buildings as with the existing navigation software, but also realize indoor route navigation, which is convenient for performing accurate navigation in all directions on the user.
