Mediated Reality Vertical Projection Harmonization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for displaying geospatial object data in mediated reality face challenges in accurately harmonizing vertical projections, leading to inaccuracies and visual distortions, especially when combining absolute and relative elevation systems, which affects the reliability and precision of MR visuals in dynamic environments.
Innovation Solution
A system and method for harmonizing vertical projections in mediated reality devices by determining the absolute elevation of the device relative to a fixed reference, using digital terrain models to align the projection plane with the physical ground, and adjusting the positioning of geospatial objects with both relative and absolute vertical positioning data to ensure accurate display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If geospatial object data with both relative and absolute vertical positioning data is displayed in mediated reality, then the system can handle diverse data types, but vertical projection harmonization becomes inaccurate and visual distortions occur
Solution Approach 1:
The patent introduces a projection plane as an intermediary reference framework that mediates between relative and absolute elevation systems. This projection plane serves as a common reference surface where both relative vertical positioning data (relative to ground surface) and absolute vertical positioning data (relative to fixed elevation reference) can be harmonized and displayed accurately together, eliminating visual distortions while maintaining versatility
2Measurement precision
If digital terrain models are used to align projection plane with physical ground, then vertical projection accuracy improves, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-determining and storing the projection plane's orientation and position relative to the fixed elevation reference before actual data display. The system pre-calculates the relationship between the projection plane and the digital terrain model, allowing for efficient harmonization of vertical projections without requiring complex real-time calculations, thus improving accuracy while managing system complexity
