Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1 and 2, a method for rapidly extracting and calculating the building area of a house comprises the following steps:
(1) calling building construction drawing or house field survey drawing data;
(2) importing the data of the construction drawing or the on-site house survey drawing in the step (1) into house property surveying and mapping production software developed based on AutoCAD;
(3) and extracting the inner area of the house and calculating the shared area of the house.
The data of the construction drawing and the house field survey drawing in the step (1) come from real estate developers and real estate surveying and mapping organizations.
The inner area of the extraction sleeve comprises the extraction of the area of the household room and the public area.
The same type of area extraction of the residential rooms and public areas has a memory function.
The area extraction has the function of expanding the edge of the outer wall, and the thickness of the outer wall can be input.
The area of a layer can be calculated, and in the house mapping production software, the calculated area in one layer can be covered in the form of shadow, and the part which is not counted is automatically displayed.
When calculating the apportionment, the following steps are adopted:
(a) classifying the common building area of the whole building;
(b) establishing a shared building area allocation grading calculation model;
(c) assigning shared building area allocation positions in a grading way;
(d) and calculating the apportioned area.
In the step (a), the shared building area to be shared can be divided into a shared building area, a shared building area of a floor and a shared building area of a functional area; the functional areas are divided into single-function areas and composite-function areas, and the single-function areas comprise commercial areas, residential areas, office areas, underground garages and other functional areas with application functions; when a plurality of different functional areas in a house are mixed together, a composite functional area is formed, such as an office house, a commercial house and the like.
In the step (b), sharing the shared building area is performed according to the principle of gradually sharing from whole to local and from large to small, namely, the shared building area is pre-shared by layers of the outer walls of each layer (shared sharing area of each layer), then shared sharing is performed, and finally functional area sharing is performed; the principle of functional distinction is as follows: if the shared area of a plurality of different functional areas exists, the shared area corresponding to the different functional areas is allocated, and then the shared area of each single function is allocated; if there is no shared area for a plurality of different functional regions, the shared area sharing for each single function is directly performed. The outer wall pre-allocation according to layers reduces the deviation of human subjective understanding on the outer wall use allocation, and the core principle of sharing the shared area according to the proportion is specified and definite.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
