Unified AR Coordinate System via Scene Image Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality systems face challenges in unifying coordinate systems across multiple user devices, especially when users are in different physical locations or unmapped areas, leading to inconsistencies in virtual environment interactions.
Innovation Solution
The system determines a common coordinate system by using location technology, image analysis, and database comparison to establish a unified origin and orientation, allowing user devices to adjust images and data transmission for consistent virtual environment presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each user device uses independent location technology (GPS, triangulation) to determine its own location, then each device can operate autonomously in any physical location, but coordinate systems become inconsistent across different physical areas leading to unrealistic virtual environment interactions
Solution Approach 1:
The patent introduces an intermediary coordinate system unification mechanism that mediates between independent device location systems. The system establishes a common coordinate system that all devices reference, transforming individual GPS/triangulation coordinates into a unified framework. This intermediary layer resolves the contradiction by allowing autonomous operation in different locations while ensuring consistent virtual environment interactions through coordinate transformation and unification.
2Reliability
If the system establishes a unified coordinate system by negotiating origin and orientation between multiple user devices, then coordinate consistency is achieved, but the complexity of determining and maintaining the common coordinate system increases
Solution Approach 1:
The patent merges multiple independent coordinate systems into a single unified coordinate system. By combining the origin and orientation parameters from different devices into one common reference frame, the system achieves coordinate consistency. This merging process simplifies the overall system by replacing multiple independent coordinate determinations with a single unified coordinate system that all devices reference, thereby reducing the net complexity despite the initial negotiation overhead.
3Measurement precision
If user devices compare scene images with database images to determine precise location, then location accuracy is improved, but the time and computational resources required for image processing and comparison increase
Solution Approach 1:
The patent applies preliminary action by pre-processing and storing reference scene images in a database before they are needed for location determination. The system captures and stores images of physical environments in advance, creating a ready-to-use reference library. When a device needs to determine its precise location, it can quickly compare its captured scene images against this pre-prepared database, significantly reducing the time and computational resources required for real-time image processing and comparison.
Data Source
AI summary
Systems and methods for unifying coordinate systems in an augmented reality application or system are disclosed. User devices capture an image of a scene, and determine a location based on the scene image. The scene image may be compared to cartography data or images to determine the location. User devices may propose an origin and orientation or transformation data for a common coordinate system and exchange proposed coordinate system data to agree on a common coordinate system. User devices may also transmit location information to an augmented reality system that then determines an a common coordinate system and transmits coordinate system data such as transformation matrices to the user devices. Images presented to users may be adjusted based on user device locations relative to the coordinate system.
