Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple oblique images are captured from multiple vantage points to improve three-dimensional modeling accuracy, then the precision of spatial modeling is improved, but the complexity of correlating vectors and pixels across multiple images increases
Solution Approach 1:
The system segments the complex task of 3D modeling into distinct processing stages: image capture from multiple vantage points, vector determination for each image, pixel correlation across images, and model generation. This segmentation allows each stage to be optimized independently, managing overall system complexity while maintaining high measurement precision through systematic multi-view processing
Solution Approach 2:
The patent introduces vector models as an intermediary representation that bridges multiple oblique images. By determining vectors from each image's focal plane to ground points and correlating these vectors across multiple images, the system creates a unified spatial reference framework that simplifies the integration of data from diverse vantage points while achieving high modeling accuracy
2Measurement precision
If photogrammetry techniques are used to determine point locations on structures, then geo-location capability is enabled, but the accuracy of point location determination is insufficient
Solution Approach 1:
The system transitions from traditional two-dimensional photogrammetry to three-dimensional vector-based spatial modeling. By determining vectors that extend from image focal planes through space to ground points, and by correlating these vectors across multiple images, the system achieves accurate 3D point location determination with error margins of 25 centimeters or better, significantly improving both accuracy and reliability of geo-location
3Ease of manufacture
If traditional oblique imaging at 45-degree angles is used to simplify geometric calculations, then ease of computation is improved, but the versatility of structural viewing and measurement is limited
Solution Approach 1:
The system generalizes the imaging geometry by allowing arbitrary vantage points and viewing angles rather than being restricted to 45-degree oblique angles. The vector determination method adapts to any imaging configuration by calculating vectors from each specific focal plane orientation to ground points, maintaining computational feasibility through systematic mathematical procedures while enabling versatile structural viewing from diverse angles and positions
