Embodiment approach

[0064] Such as figure 1 As shown, an implementation method for creating a 3D architectural model through a wireframe diagram of a building comprises the following steps:

[0065] (1) Image processing; processing the sporadic details or distorted places in the image;

[0066] (2) wireframe identification; on the basis of the picture processed in step (1), identify the wireframe of the line in the figure;

[0067] (3) 3D geometry is generated; on the basis of the wireframe data identified in step (2), generate a one-storey high geometry shape;

[0068] (4) Floor generation; generate a single-story structure 3D map of the building, including the floor, and copy this layer structure to other floors with the same structure;

[0069] (5) Building generation; repeat the above steps (1)-step (4) to build the whole building.

specific Embodiment approach

[0070] The invention provides a method for quickly creating a 3D model of a building. The operator manually adds a building plane picture, and the program analyzes the building picture provided by the user, and returns the corresponding building structure array. The analysis array is combined with the user input The building condition parameters can be used to generate the floor structure geometry, provide manual addition and position adjustment of the public model, bind the unique identifier for the constructed building, and add building internal resources to the building on the management side, enrich building information, improve building model and The consistency of the actual building; the specific implementation is as follows:

[0071] Step 101: Enter the modeling page, which provides a 3D modeling operation environment based on WEB;

[0072] Step 102: choose to import architectural pictures;

[0073] Step 103: return the content of the building picture, the user can ma...

Abstract

The invention discloses an implementation method for creating a 3D building model through a wireframe diagram of a building. The implementation method comprises the following steps: (1) picture processing; processing sporadic details in the picture or distorted places in the picture; (2) wireframe identification; on the basis of the picture processed in the step (1), identifying a line frame of aline in the picture; (3) 3D geometry generation; on the basis of the wireframe data identified in the step (2), generating a geometry-shaped body with a floor height; (4) generating floors; generatinga single-layer structure 3D graph of the building, including a floor, and copying the structure of the floor to other floors with the same structure; (5) building generation; and repeating the steps(1)-(4) to construct the whole building. According to the method, the modeling speed is greatly increased, the modeling difficulty is greatly reduced, the method can be applied to 3D model creation ofnon-3D professional technicians, concerned building structures and unconcerned building soft decoration aspects, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of building 3D model building, in particular to a method for creating a 3D building model through building wireframes. Background technique [0002] The three-dimensional form of expression can display an object in all directions, and has incomparable advantages over two-dimensional plane images. Enterprises publish their products in a three-dimensional form on the Internet, which can show all aspects of product appearance, plus interactive operations, demonstrate product functions and operations, and make full use of the advantages of high-speed and rapid Internet communication to display products. [0003] Use Web3D to realize the display on the network, and people can walk through it from the first perspective. There can be interaction between the scene and the controller, which makes people feel immersive. Solutions are provided for things like virtual exhibition halls and virtual tours of buildings. ...
