Abstract

The invention discloses a reconstruction method for a three-dimensional quadrilateral mesh model on the basis of an image. The method comprises the following steps that: (1) obtaining point cloud datawhich represents an image object or a scene appearance, and recovering the three-dimensional image of an image; and (2) constructing the quadrilateral mesh of the point cloud data, and reconstructingthe quadrilateral mesh model. The method has the advantages that the method has an effect on fitting the better image object or scene.

Description

technical field [0001] The invention relates to an image-based three-dimensional quadrilateral mesh model reconstruction method. Background technique [0002] With the continuous development of computer software and hardware technology, real-time rendering of large-scale complex scenes has become possible, which puts forward new requirements for the complexity and realism of the model. Although traditional 3D modeling tools are improving day by day, building complex 3D models is still a very time-consuming and laborious task. Since many 3D models can be found or modeled in the real world, image-based modeling techniques have become the ideal modeling method in people's minds. In addition, traditional 3D modeling generally can only obtain the geometric information of the scene, while image-based 3D modeling provides a natural way to generate photo-realistic synthetic images, and has become a hot spot in the field of computer graphics. , It is widely used in digital preserva...
