Mediated Reality Positioning Offset for Virtual Camera Pose
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current geospatial data collection methods, especially in mediated reality systems, face inaccuracies due to the cumbersome and time-consuming validation techniques required for positioning devices, particularly when these devices are tilted or moved, leading to significant positioning shifts that affect the accuracy of virtual camera poses in augmented reality applications.
Innovation Solution
A computer-executable method and system that determine a mediated reality positioning offset for a virtual viewpoint by calculating the geometric difference between initial and updated positioning parameters, incorporating roll, pitch, and yaw, and adjusting the placement of virtual geospatial objects using these offsets to maintain accurate positioning and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If validation techniques are used to verify positioning data, then reliability of geospatial data is improved, but time consumption and operational complexity increase
Solution Approach 1:
The system performs preliminary calibration by establishing a neutral position offset between the positioning device and virtual viewpoint before actual geospatial data collection. This preliminary action stores baseline parameters that are later used to automatically correct positioning data, eliminating the need for time-consuming validation techniques during field operations while maintaining high accuracy.
2Adaptability or versatility
If the positioning device is tilted or moved from neutral position, then operational flexibility is improved, but positioning accuracy deteriorates due to tilt-induced shifts
Solution Approach 1:
The system applies preliminary anti-action by calculating and storing offset parameters between the positioning device and virtual viewpoint in the neutral position. When the device is tilted or moved, these pre-calculated offsets are used to compensate for tilt-induced shifts, allowing the device to maintain positioning accuracy even when operated in tilted or moved positions, thus providing operational flexibility without sacrificing precision.
3Device complexity
If manual measurements are used to collect geospatial data, then equipment complexity is reduced, but measurement precision and data quality deteriorate
Solution Approach 1:
The system introduces an intermediary computational layer that automatically calculates positioning offsets between the positioning device and virtual viewpoint using stored neutral position parameters. This intermediary process corrects raw positioning data in real-time, enabling the system to maintain high measurement precision while using relatively simple positioning devices without requiring complex manual validation procedures.
