Problems solved by technology

[0002] At present, for the protection and restoration technology of large historical relics, such as large buildings, there is a problem that it is impossible to obtain the comprehensive status of the buildings
Therefore, it is impossible to provide effective reference in the process of restoration plan discussion and actual restoration process
[0003] At the same time, the data acquisition technology in the existing 3D modeling technology is based on 3D laser scanning equipment, but because the 3D laser scanning equipment is limited to flat mobile scanning, it is impossible or difficult to obtain information on the top of high-rise buildings
Limited by the acquisition of some data, the laser scanning of large buildings cannot achieve the integrity of the scanning data
[0004] Moreover, the existing 3D modeling technology still has the problem that 3D point cloud data and image data cannot be matched, modeled and output in the same processing software
As a result, there are complex problems in the operation of the 3D modeling process

Embodiment 1

[0062] Please refer to figure 2 , the present embodiment provides a method for restoring architectural cultural relics based on three-dimensional modeling technology, including:

[0063]S1: Obtain all-round image data of architectural cultural relics through oblique photography of drones;

[0064] Specifically, the UAV is used to obtain all-round image data including high-level image data of architectural cultural relics by attaching an oblique camera. The photographic data of one of the angles of view such as image 3 shown.

[0065] S2: Constructing and obtaining a three-dimensional real-scene model corresponding to architectural cultural relics according to the image data;

[0066] First obtain the corresponding 3D point cloud data based on the image data, such as Figure 4 As shown, and then construct a 3D real scene model based on this, such as Figure 5 shown. According to the image data obtained by the drone, which is different from the data obtained by the 3D la...

Embodiment 2

[0091] This embodiment is a specific application scenario corresponding to Embodiment 1:

[0092] With the maturity of UAV technology and 3D printing, it has brought new possibilities for the restoration and reconstruction of cultural heritage, and has broad research and application prospects in the field of cultural heritage restoration and reconstruction. Oblique photography (UAV) technology can simultaneously collect images from five different angles, including one vertical and four obliques, to obtain complete and accurate information on large areas of the ground. This embodiment makes full use of its advantages, scans all aspects of cultural heritage objects, obtains the best point cloud renderings, obtains complete cultural heritage geometry, topology, and texture information more accurately, and provides high-performance digital scanning analysis. Conservation efforts are more effective. The creation of 3D digital archives of cultural heritage through drone acquisition...

Embodiment 3

[0095] This embodiment corresponds to Embodiment 1. It provides a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor, it can realize the above-mentioned three-dimensional modeling technology-based method for restoring architectural cultural relics. A step of. The specific steps will not be repeated here, please refer to the description of Embodiment 1 for details.

[0096] In summary, the restoration method and storage medium for architectural cultural relics based on 3D modeling technology provided by the present invention can obtain high-precision, high-fidelity restored 3D models and 3D repaired part models, providing an intuitive and convenient Comprehensive and detailed references improve restoration efficiency and professionalism.

Abstract

The invention provides a building cultural relic restoration method based on a three-dimensional modeling technology and a storage medium. The method comprises the steps: acquiring an omnibearing three-dimensional live-action model corresponding to a building cultural relic; According to the three-dimensional real scene model, constructing a fractured curved surface of a to-be-repaired part on thebuilding cultural relic through reverse engineering software; Obtaining a three-dimensional repair part model constructed according to the fracture curved surface and the three-dimensional real scenemodel; And matching the repaired part model with the fracture curved surface to obtain a repaired three-dimensional model. According to the method, a high-precision and high-fidelity repaired three-dimensional model and a three-dimensional repaired part model can be obtained, a visual, comprehensive and detailed reference basis is provided for the repairing work of the building cultural relics, and the repairing efficiency and professionality are improved.

Description

technical field [0001] The invention relates to the field of three-dimensional modeling, in particular to a method for restoring architectural cultural relics and a storage medium based on three-dimensional modeling technology. Background technique [0002] At present, for large-scale historical relics, such as the protection and restoration technology of large buildings, there is a problem that it is impossible to obtain the comprehensive status of the buildings. Therefore, it is impossible to provide an effective reference in the restoration plan discussion process and the actual restoration process. [0003] At the same time, the data acquisition technology in the existing 3D modeling technology is based on 3D laser scanning equipment, but because the 3D laser scanning equipment is limited to flat mobile scanning, it is impossible or difficult to obtain information on the top of large buildings. Limited by the acquisition of some data, the laser scanning of large buildin...
