The top-level merging of the 3D model of the oblique photography of the super-large scene is of great significance and application value for the construction of accurate, complete and realistic 3D models. This article will examine its importance from several aspects.
1. Model integrity and coherence.
The top-level merging of the 3D model of the oblique photography of very large scenes can fuse multiple oblique photography data into a single model, so as to achieve the integrity and coherence of the model. Through merging, the fractures and contradictions between different perspectives can be eliminated, and the missing data can be filled, making the final model more complete, realistic and coherent spatial structure.
2. High-precision geographic information acquisition.
The top-level merging of 3D models of oblique photography of very large scenes can provide high-precision geographic information. Due to the high resolution and accuracy of oblique photographic data, more details and morphological features of ground objects, including buildings, roads, trees, etc., can be preserved through top-level merging. This is very important for urban planning, land use, resource management and other fields, and provides reliable data support for decision-making and refined management.
3. Extraction and analysis of ground features.
The top-level merging of the 3D model of the oblique photography of the super-large scene can provide rich information about the features and support the automatic extraction and analysis of the figures. By fusing data from multiple perspectives, more comprehensive and accurate features can be obtained. With the continuity and consistency of the model, you can quickly and accurately identify and classify objects such as buildings, roads, vegetation, and other objects. This is very important for urban management, environmental monitoring, disaster assessment, infrastructure planning, etc., and helps to improve work efficiency and decision-making.
4. Visualization and roaming.
The top-level merging of the 3D model of the oblique photography of the very large scene can realize the visualization and walkthrough of the model. By projecting the model into a virtual environment, people can get a realistic display of the scene and roam freely. This has important application value in urban planning, tourism promotion, scenic spot guidance, etc. At the same time, it can also be based on the model for ** and visual analysis to evaluate the effect of different planning schemes.
5. Accuracy control and model optimization.
The top-level merging of 3D models of oblique photography of very large scenes can improve the accuracy and precision of the model through precision control and model optimization. By registering and correcting the data of each viewing angle, the coordinate conversion and error correction problems between different viewing angles are solved. At the same time, model optimization technology can be applied to optimize and adjust the model to further improve the accuracy and precision of the model. This is particularly important for detailed research and analysis requirements, such as building deformation monitoring, volume calculation, and surface change analysis.
In conclusion, the top-level merging of the 3D model of the oblique photography of the super-large scene is of great significance and application value for the construction of an accurate, complete and realistic 3D model. It can ensure the integrity and coherence of the model, provide high-precision geographic information, support the extraction and analysis of ground objects, realize visualization and roaming, and improve the accuracy and precision of the model through precision control and model optimization. With the continuous development of technology and the deepening of applications, the top-level merging of 3D models of oblique photography of super-large scenes will play an important role in more fields.
