A method and system for automatic processing of floor plans

Abstract

The invention relates to an automatic processing method and system for a floor plan, belonging to the technical field of computer-aided design. This paper proposes a method for automatic generation of apartment space area. The designer can automatically generate the area by drawing the wall. The bottom point of the wall is the same as the edge point of the area, and there will be no error in numerical accuracy, which is beneficial to other functions of the home improvement design software. At the same time, the present invention also proposes a method for automatic space grouping suitable for villas or small high-rise units, which can save resource investment, help designers to design schemes like ordinary flat-story houses, and automatically calculate floor space. The grouping relationship can reduce the designer's work pressure; the invention also proposes a method for quickly locating the local maximum rectangle and the center position of the area based on deep learning.

Description

technical field [0001] The invention relates to an automatic processing method and system for a floor plan, belonging to the technical field of computer-aided design. Background technique [0002] In the existing home improvement design software, the generation effect of space area is not very ideal: some spaces enclosed by small walls are also marked as areas (actually the internal space of flues or other components, such as figure 1 As shown in the figure, in a room, some commonly used accessories also need to be compiled into a small polygon, and many software will mistakenly classify such a small polygon area as a room when recognizing the room area of ​​the floor plan) , and some software generates regions by manually drawing polygons by designers, which will cause numerical errors between the edge of the region and the edge of the wall, which will affect the use of other functions (such as judging products in the area space, when the product is hung on the wall) For p...

Problems solved by technology

Usually, the calculation of the local maximum rectangle and the approximate center position under the apartment space adopts the general geometric graphics method. This method is often calculated through the constraints of geometric regularity. It is inevitable that special apartment types will not be covered by the rules, resulting in The positioning of the local maximum rectangle is inaccurate, the calculation deviation of the best approximate center position, etc.
