Embodiment Construction

[0042] The specific implementation of the symmetrical reconstruction method of the three-dimensional model of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] See attached figure 1 , The symmetrical object is scanned by a 3D scanning device to obtain a 3D model. The 3D model can be a point cloud model or a triangular mesh surface model. The data volume of the 3D model should preferably exceed half of the data of the entire object, and be imported into the computer memory for the reconstruction process of the 3D model.

[0044] See attached Figures 2 to 4 , the present invention is described in detail below in conjunction with the three-dimensional model reconstruction process of the sharp-billed jug, and the specific steps are as follows:

[0045] (1) Find the plane of symmetry and central axis of symmetry of the 3D model. The central axis of symmetry and the plane of symmetry of the 3D model can be obtained thr...

Abstract

The invention relates to the technical field of 3D data processing, and discloses a symmetric reconstruction method of a three-dimensional model, and the method comprises the following steps: (1) finding a symmetric plane and a symmetric central axis of the three-dimensional model; (2) aligning a symmetry plane and a view plane of the three-dimensional model, and enabling the front surface of the three-dimensional model to be visible; (3) judging whether the three-dimensional model is a symmetric central axis symmetric model or a plane symmetric model; (4) performing symmetric reconstruction on the three-dimensional model with the symmetric central axis in rotational symmetry; (5) performing symmetric reconstruction on the three-dimensional model with symmetric planes. According to the invention, through analysis and operation of modeling data, automatic reconstruction of the symmetric three-dimensional model is automatically completed.

Description

technical field [0001] The invention relates to the technical field of 3D data processing and modeling, in particular to a symmetrical reconstruction method of a three-dimensional model. Background technique [0002] The 3D data modeling of the scanned object through the camera can realize the digitization of the data of the object and realize the digital processing of each parameter of the object, such as calculating the surface area, volume and other parameters of the object. In the modeling process, since the camera can only scan a part of the data at a time, in order to build a complete data model, it is necessary to scan the object multiple times and then stitch the data together. [0003] For symmetrical objects, due to the symmetry of the data, when there are more than half of the data, the modeling data can theoretically be completed by operations such as mirroring and flipping. However, when the filling operation is better than human-machine operation, the operatio...
