Problems solved by technology

[0005] To sum up, the main problem in the existing technology is that the restoration of 3D information of image objects or scenes is greatly affected by image quality, camera calibration and matching algorithms, and the robustness and accuracy need to be improved.
In addition, there are also problems such as the low efficiency of large-scale point cloud data recovery, the reconstruction of geometric models is relatively simple, and the lack of a complete process from image acquisition to multiple model reconstruction, so new modeling methods are needed to better fit image object or scene

Abstract

The invention discloses an image-based three-dimensional quadrilateral grid model reconstruction method, comprising: step (1): acquiring point cloud data representing the shape of an image object or scene, and recovering the three-dimensional information of the image; step (2): constructing a point cloud The four-sided grid of the data, to reconstruct the four-sided grid model. It has the advantage of fitting better image objects or scenes.

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...
