3D Model Reconstruction Using Adjacent-Structure Similarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D modeling techniques fail to effectively address hollows created when objects are moved or deleted in simulated spaces, leading to incomplete spatial models.
Innovation Solution
The method involves extending adjacent structures in a 3D model to cover hollows based on similarity analysis, determining a target structure to compensate for the hollow, and restoring the spatial model by assigning appropriate materials.

Engineering Contradiction Analysis
1Adaptability or versatility
If objects are moved or deleted in simulated space, then the simulated space can be modified, but hollows are created that make the spatial model incomplete
Solution Approach 1:
The system performs preliminary scanning and modeling of the real space to create a complete 3D model before any objects are moved or deleted. This initial complete model serves as a reference to identify and fill hollows created by subsequent object modifications, ensuring the spatial model remains complete.
Solution Approach 2:
The system creates a copy of the original complete spatial model and uses it to fill hollows in the modified model. By comparing the original model with the modified model, the system identifies hollow regions and fills them with corresponding structural information from the original model, maintaining completeness.
2Ease of manufacture
If traditional scanning methods are used to create simulated space, then the process is simple, but hollows cannot be effectively compensated
Solution Approach 1:
The system implements a feedback mechanism where the 3D model is continuously compared between the original scanned model and the modified model. Hollow regions are detected through this comparison, and the system automatically fills these hollows by referencing the original model, providing accurate compensation while maintaining process simplicity.
Solution Approach 2:
The system segments the spatial model into distinct structures and identifies hollow regions as separate segments. By treating hollow compensation as a distinct segmentation task, the system can apply specific filling algorithms to each hollow region independently, improving accuracy without complicating the overall process.

AI summary
A reconstruction method of a three dimensional (3D) model and a computing apparatus are provided. In the method, multiple structures in the 3D model are determined. An object in the 3D model is separated from an original location to form a hollow. The hollow is adjacent to at least two neighboring structures among the structures. The neighboring structures are respectively extended to cover the hollow. A similarity of an extended part covering the hollow is determined. The similarity is a compared result of an adjacent structure of the extended part. A target structure of the hollow is determined according to the similarity. The target structure is used for compensating the hollow.
