Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If photogrammetry is combined with multiple technologies (mobile objects, surveying instruments, data processing technologies, BIM), then the application scope and functionality are improved, but the complexity of data and information management increases
Solution Approach 1:
The patent segments the integrated system into distinct functional modules: mobile object module, surveying instrument module, data processing module (SfM, MVS, SLAM), and BIM module. Each module generates and manages its own data according to standardized formats, allowing independent development and maintenance while contributing to the overall photogrammetry system. This modular segmentation reduces the complexity of managing integrated multi-technology data.
2Reliability
If comprehensive data management is implemented for integrated photogrammetry systems, then the consistency and efficiency of information management are improved, but the system complexity and implementation difficulty increase
Solution Approach 1:
The patent establishes a universal data management framework that handles multiple types of data (mobile object data, surveying instrument data, processed photogrammetry data, BIM data) through standardized interfaces and common processing protocols. This universal framework enables consistent data management across diverse data sources while maintaining a unified system architecture, thereby improving reliability without proportionally increasing implementation complexity.
Data Source
AI summary
One aspect example is a system for photogrammetry of a building. A memory stores design data and physical material data. The design data includes virtual material information on attributes for each of virtual materials of a virtual building. The physical material data is on the attributes for each of physical materials and generated based on measured data acquired from a physical building constructed on the basis of the design data. A material associating processor is configured to generate pairs of virtual and physical materials by determining an association between the virtual materials and the physical materials based on the virtual material information and the physical material data. An attribute associating processor is configured to determine an association between the virtual material information and the physical material data in accordance with the attributes for each of the pairs.
