Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voxel data representing three-dimensional structures often require a large amount of data due to the need for high-resolution representation of both geometric and attribute information, leading to inefficiencies when a single resolution level is assigned.
Innovation Solution
An information processing apparatus that uses a processor to acquire volume data with multiple resolution levels for both geometric and attribute layers, allowing for the assignment of characteristic and attribute values to voxels based on their position and resolution level, enabling efficient data management by separating geometric and attribute information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single resolution level is assigned to voxels to represent both geometric and attribute information, then the representation is simplified, but the data amount becomes huge
Solution Approach 1:
The patent applies local quality by assigning different resolution levels to different spatial regions based on their specific needs. Geometric layers use finer resolution in regions with complex shapes, while attribute layers use coarser resolution in regions with gradual property variations. This localized adaptation of resolution quality reduces overall data storage requirements while maintaining necessary representation accuracy in critical areas.
Solution Approach 2:
The patent segments the voxel data representation into multiple independent layers, where each layer is assigned a specific resolution level appropriate for its content type. Geometric layers are separated from attribute layers, allowing independent resolution optimization for each layer type, thereby reducing the total data amount compared to a unified high-resolution representation.
2Measurement precision
If high-resolution representation is used for both geometric and attribute information, then accuracy is improved, but data storage requirements increase significantly
Solution Approach 1:
Different resolution levels are applied locally to different information types: geometric layers maintain high resolution in regions requiring shape accuracy, while attribute layers use lower resolution where property variations are gradual. This localized quality assignment preserves necessary accuracy for each information type while minimizing overall data storage requirements.
Solution Approach 2:
The patent divides the data structure into segmented layers (geometric layers and attribute layers), each with independently optimized resolution levels. This segmentation allows high accuracy to be maintained only where necessary for each layer type, rather than applying uniform high resolution across all data, thus reducing total storage while preserving accuracy where needed.
3Quantity of substance
If different resolution levels are used for geometric and attribute information, then data efficiency is improved, but data structure complexity increases
Solution Approach 1:
The patent manages the increased data structure complexity by segmenting information into distinct geometric layers and attribute layers, each with their own resolution levels. This segmentation provides a clear organizational framework that makes the multi-resolution structure manageable and accessible, offsetting the inherent complexity through systematic organization.
Solution Approach 2:
The patent resolves structural complexity by adding a layer dimension to the data organization, where multiple layers stack vertically with each layer having its own resolution characteristics. This dimensional approach to organization allows efficient access and management of multi-resolution data without requiring complex cross-referencing or inter-layer coordination.
