Virtual Scene Generation from Real 3D Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for establishing virtual scenes are inefficient due to manual modeling of objects and potential unreasonable logic in randomly generated scenes, leading to high labor costs and low efficiency.
Innovation Solution
A virtual scene generation method that acquires three-dimensional space data and scene distribution data from a real scene, extracts terrain and object features, and generates corresponding three-dimensional models to create a virtual scene automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If independent manual modeling is performed on each object in the virtual scene, then the virtual scene can be established with high precision, but the time consumption and labor costs increase significantly
Solution Approach 1:
The patent uses real-world scene data (point cloud data, images, videos) as copies of the actual environment to automatically generate virtual scene models. Instead of manually modeling each object, the system captures and processes real scene data to create accurate 3D representations, thereby maintaining high precision while dramatically reducing time consumption and labor costs.
2Extent of automation
If virtual scenes are randomly generated using programming tools, then the generation process is automated, but the scenes may contain unreasonable logic requiring manual repair
Solution Approach 1:
The patent employs feedback mechanisms by using real scene data as a reference to validate and adjust the generated virtual scene. The system compares the automatically generated models against the original point cloud data, images, and videos, ensuring that the virtual scene accurately reflects the real environment's logical relationships and spatial structures, thereby maintaining reliability while achieving automation.
3Reliability
If manual repair is performed on randomly generated scenes, then the scene logic can be corrected, but the overall efficiency of virtual scene establishment remains low
Solution Approach 1:
The patent performs preliminary actions by capturing and processing real scene data before virtual scene generation. By pre-processing point cloud data, images, and videos to extract accurate geometric and semantic information, the system establishes a reliable foundation that eliminates the need for subsequent manual repair work, thereby maintaining high reliability while significantly improving overall productivity.

AI summary
A computer device acquires three-dimensional space data and scene distribution data corresponding to a real scene. The computer device extracts terrain features from the three-dimensional space data and generates a three-dimensional terrain model according to the terrain features. The computer device extracts, from the scene distribution data, scene object features of scene objects in the real scene. The computer device generates scene object models corresponding to the scene object features in the three-dimensional terrain model to obtain a virtual scene corresponding to the real scene.
