Embodiment Construction
[0040] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0041] Such as figure 1 As shown, a large-scale building information model and three-dimensional digital city integration method is characterized in that it includes the following steps:
[0042] Step 1: Build a building information model.
[0043] Step 2, extracting and storing building component information.
[0044] Step 3: Integrate the building component information data with the 3D digital city.
[0045] The extraction and storage of building component information is carried out in the following steps:
[0046] A1. Extract building component information of walls, slabs, columns, stairs, doors, windows, railings and roofs.
[0047] A2. Establish the building component information model semantics, and store the acquired building component information in the building information database; the building component information model semantics include: the ...
