Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D reconstruction techniques often result in inconsistent and inaccurate models due to varying capture and reconstruction methods, leading to distortions, missing data, and incomplete representations of building environments.
Innovation Solution
Aligning disparate 3D models of a common building object using a common coordinate system, based on shared architectural features and location information, to integrate and refine the models, addressing distortions and gaps through correlation, alignment, and scaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple 3D models are generated using different capture and reconstruction techniques, then diverse data sources can be utilized, but inconsistencies and inaccuracies arise in the resulting models
Solution Approach 1:
The patent combines multiple disparate 3D models (interior and exterior) into a single unified model by aligning them in a common coordinate system. This merging process integrates data from different capture techniques while eliminating inconsistencies, thereby maintaining model accuracy despite using diverse data sources.
Solution Approach 2:
The patent introduces a common coordinate system as an intermediary framework to facilitate the alignment and integration of models generated from different capture techniques. This mediator enables consistent spatial relationships between interior and exterior models while preserving the integrity of each individual model's data.
2Ease of manufacture
If disparate 3D models are generated independently, then specialized capture techniques can be applied to specific areas, but distortions and missing data occur in the final representation
Solution Approach 1:
The patent merges independently generated interior and exterior models into a unified representation, thereby compensating for individual model limitations. The combination fills gaps in one model using data from the other, ensuring complete and reliable building environment representation while maintaining the flexibility to use specialized capture techniques for specific areas.
3Loss of information
If multiple modeling techniques are used to capture different building aspects, then comprehensive data collection is achieved, but spatial inconsistencies arise between models
Solution Approach 1:
The patent employs a common coordinate system as an intermediary to establish consistent spatial relationships between interior and exterior models. This mediator ensures that all models share a unified spatial reference framework, eliminating spatial inconsistencies while preserving the comprehensive data collected through multiple modeling techniques.
4Object-generated harmful factors
If interior and exterior models are created separately, then specialized processing can be applied to each, but integration and alignment become complex
Solution Approach 1:
The patent introduces a common coordinate system as a standardized intermediary that simplifies the integration process. By providing a unified reference framework, this mediator enables straightforward alignment and correlation of interior and exterior models, reducing integration complexity while allowing specialized processing to be applied to each model type before combination.

AI summary
Methods, storage media, and systems for combining disparate 3d models of a common building object are disclosed. Exemplary implementations may: receive a first plurality of images; generate a first 3d model based on the first plurality of images; receive a second plurality of images; generate a second 3d model based on the second plurality of images; and align, in a common 3d coordinate system, the first 3d model with the second 3d model.
