Virtual three-dimensional reconstruction and scene creation method for building

Abstract

The invention discloses a virtual three-dimensional reconstruction and scene creation method for a building, and belongs to the field of three-dimensional graphic design, and the creation method comprises the following specific steps: (1) collecting basic information and environment information of the building; (2) enabling the modeling software to start to construct a building model and an environment model; (3) receiving the scene information, and starting the virtual scene construction; (4) performing detail optimization on the constructed scene; (5) carrying out data annotation on the virtual model and generating a related design document. According to the method, coordination judgment and optimization can be automatically carried out on the building, scene design and environment, the environmental coordination between the building and scene design and the surrounding environment is improved, the requirement for harmonious development of people and the nature is met, the natural environment is protected, resources are saved, workers do not need to manually mark all parts of the building, the time for writing the design document by workers is saved, and the working efficiency of the workers is improved.

Description

technical field [0001] The invention relates to the field of three-dimensional graphic design, in particular to a method for virtual three-dimensional reconstruction and scene creation of buildings. Background technique [0002] Three-dimensional reconstruction refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects, which is the basis for processing, operating and analyzing its properties in a computer environment, and is also a key technology for establishing a virtual reality that expresses the objective world in a computer. In computer vision, 3D reconstruction refers to the process of reconstructing 3D information from single-view or multi-view images. Since the information of a single video is incomplete, 3D reconstruction needs to utilize empirical knowledge. The 3D reconstruction of multi-view is relatively easy. The method is to calibrate the camera first, that is, calculate the relationsh...

[0003] After retrieval, Chinese Patent No. CN109035412A discloses a method for virtual three-dimensional reconstruction and scene creation of buildings. Although the invention can realize accurate and fast three-dimensional reconstruction and scene reconstruction of buildings, it cannot perform real-time reconstruction of buildings, design scenes and environments. Coordination judgment and optimization, reducing the environmental coordination between the building and the design scene and the surrounding environment, which does not meet the needs of the harmonious development of man and nature, and destroys the natural environment; in addition, the virtual 3D reconstruction of existing buildings and virtual scenes require staff Manually marking each part of the building and saving 3D model diagrams from different perspectives wastes staff time and reduces staff work efficiency; therefore, we propose a virtual 3D reconstruction and scene creation method for buildings
