Problems solved by technology
However, compared with the three-dimensional floor plan, there are shortcomings such as not being intuitive enough, and the degree of display is low.
3D apartment type modeling is not widely used in the real estate industry due to its complex technology and the need for professional engineering and technical personnel
[0014] 1. The modeling is highly professional, the design is complex and difficult, and skilled modeling engineers are required
[0015] 2. The operation is complicated, there are many parameters, and the learning cost is very high
[0016] 3. Professional modeling desktop software and hardware are required, which cannot meet the needs of rapid modeling on mobile terminals

The invention discloses a two-dimensional house type and three-dimensional presentation method based on Android. The method comprises the following steps that: extracting and classifying two-dimensional floor plan information, and constructing three-dimensional floor plan modeling element; selecting a two-dimensional floor plan of an image format, properly clipping and correcting a dimension on the two-dimensional house type picture, and carrying out a binaryzation operation and a morphological operation on the two-dimensional house type picture; extracting the basic data of each modeling element subjected to three-dimensional drawing; automatically drawing a three-dimensional floor plan; and realizing a purpose that the three-dimensional floor plan is subjected to a roaming operation through a gesture operation. By use of the method, three-dimensional presentation of the two-dimensional house type on the mobile terminal can be quickly and conveniently identified, and in addition, a convenient interaction operation is provided. Therefore, the method has the characteristics of being low in modeling difficulty and high in efficiency, the user can be assisted in comprehension, and user experience is improved.
Description
