Three-dimensional house automatic modeling method and implementation based on cloud computing

Abstract

The invention discloses a three-dimensional house automatic modeling method based on cloud computing, which comprises the steps of: processing real estate surveying and mapping data to obtain two-dimensional GIS data; generating wall body two-dimensional contour lines according to the two-dimensional GIS data; and combining the wall body two-dimensional contour lines with a house elevation attribute value in the real estate surveying and mapping data to generate a house three-dimensional model composed of a house wall body three-dimensional model, a house bottom surface three-dimensional model, a house top surface three-dimensional model, a floor wall body three-dimensional model and a floor top surface three-dimensional model. The three-dimensional house automatic modeling method realizes the establishment of the house three-dimensional model, reflects the internal details of the three-dimensional real estate model more intuitively, demonstrates the house construction in all directions, and provides the user with better viewing experience of the three-dimensional house model. The invention further discloses a three-dimensional house automatic modeling system based on cloud computing, which has the above effects.

Description

technical field [0001] The invention belongs to the technical field of geographic information systems, and relates to a method for automatic modeling of a three-dimensional house based on cloud computing, and also relates to a system for automatic modeling of a three-dimensional house based on cloud computing. Background technique [0002] In the field of geographic information system, the real geographic world is described in the computer through geographic information system GIS. With the continuous development of 3D geographic information technology and urban housing construction, 3D architectural models are becoming more and more important in the field of housing construction. Every city spends a lot of manpower, material and financial resources on the production of 3D architectural models. Because it can reflect the real situation of housing construction to the greatest extent, it provides a lot for users to intuitively understand the types of houses and parameters from ...

Problems solved by technology

In order to obtain a 3D building model, you must first obtain 3D building model data. However, the current acquisition of 3D building model data is not complete, resulting in most of the 3D building models can only show the appearance of the building, but cannot show its internal structure, that is, because The production technology of 3D building model data has become a huge obstacle to the application of 3D geographic information technology.
