House type image automatic processing method and system

Abstract

The invention relates to a house type image automatic processing method and system, and belongs to the technical field of computer aided design. According to the method for automatically generating the house type space area, a designer can automatically generate the area by drawing the wall body, the bottom point of the wall body is the same as the edge point of the area, errors of numerical precision cannot occur, and expansion and use of other functions of home decoration design software are facilitated; meanwhile, the invention further provides an automatic space grouping method suitable for villas or small high-rise apartments, resource investment can be saved, designers can be helped to conduct scheme design like drawing of ordinary flat-floor residences, the grouping relation of floor spaces is automatically calculated, and the working pressure of the designers can be relieved. The invention further provides a method for quickly positioning the local maximum rectangle and the regional center position of the house type space based on deep learning.

Description

technical field [0001] The invention relates to a method and system for automatically processing house type drawings, belonging to the technical field of computer-aided design. Background technique [0002] The existing home decoration design software, the generation effect of the space area is not very ideal: some spaces surrounded by small walls are also marked as areas (actually the internal space of the flue or other components, such as figure 1 As shown, in a room, because some commonly used appendages 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 areas by manually drawing polygons by designers, which will cause numerical errors between the edge of the area and the edge of the wall, and affect the use of other functions (such as determining the product under the area space, when the product is hung on the wal...

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.
