[0003] House type Figure 1 Generally, the spatial layout information of the house type is displayed to the owner in a two-dimensional form, which requires the owner to have a certain spatial imagination ability. This method is obviously not in line with the natural way of human cognition of the world.

Embodiment 1

[0068] Such as figure 1 As shown, the wall, door and window information acquisition method for three-dimensional apartment type reconstruction disclosed by the present invention includes the following steps:

[0069] Step 1. Obtain the structural information of the wall from the wall diagram: first preprocess the wall diagram to remove the residual noise in the wall diagram; then refine the preprocessed wall diagram to obtain the wall centerline ;Finally, the center line of the wall is corrected to obtain the structural information of the wall; the wall map is obtained by cutting and identifying the floor plan, and the method of identifying and cutting is usually completed by fast fuzzy C clustering algorithm, and the identification is usually done by artificial neural network Completed by the network, the wall map in the present invention does not contain non-architectural information such as home furnishing;

[0070] Step 2. Obtain the structural information of doors and w...

Abstract

The invention provides a wall and door and window information acquisition method for three-dimensional house type reconstruction, which comprises the following steps: acquiring structural informationof a wall from a wall map: firstly preprocessing the wall map, and removing residual noise in the wall map; carrying out refining operation on the preprocessed wall body map to obtain a wall body center line; and finally, correcting the center line of the wall body to obtain the structural information of the wall body; obtaining structural information of doors and windows from the wall chart; firstly, cutting door and window subgraphs in the house type chart according to the position relation of the doors and windows and walls; and identifying the door and window subgraphs at the cut positions. The wall body and door and window information acquisition method can quickly and effectively extract wall body and door and window information, and can provide effective guarantee for subsequent three-dimensional house type reconstruction.

Description

technical field [0001] The invention relates to a method for obtaining information on walls, doors and windows, in particular to a method for obtaining information on walls, doors and windows for three-dimensional house type reconstruction. Background technique [0002] The advancement of China's urbanization process has brought about a rapid increase in the demand for urban housing, followed by a large increase in the demand for interior decoration. For the interior decoration industry, the use of 3D decoration design software has greatly improved the work efficiency of interior design and improved the expression ability of interior design effects. Three-dimensional decoration software is essentially a three-dimensional CAD design system. Compared with two-dimensional CAD systems, the three-dimensional expression method is more in line with human cognition, and can more accurately and intuitively express the designer's original design ideas. But at the same time, compared ...
