Mixed Reality Local Map Decoupling via 3D Platform Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mixed-reality systems face challenges in tracking and displaying holograms accurately when the device is on a moving platform, leading to map corruption and low-quality tracking.
Innovation Solution
The system determines the type of moving platform and generates a three-dimensional boundary to limit scanning data, allowing for the creation of a local map that remains decoupled from the global map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the MR system uses a global map for tracking in moving platforms, then the system can maintain continuity with stationary environments, but the map becomes corrupted and tracking quality deteriorates
Solution Approach 1:
The patent divides the mapping system into two separate components: a global map for stationary environments and a local map for moving platforms. This segmentation prevents the corruption of the global map by moving platform data while maintaining dedicated tracking functionality for each environment type. The system switches between global and local maps based on detected platform motion.
Solution Approach 2:
The patent introduces an intermediary mechanism (platform motion detection system) that monitors whether the device is on a moving platform and triggers the appropriate map switching. This intermediary layer prevents direct contamination between global and local mapping data while enabling seamless transitions between tracking modes.
2Loss of information
If the MR system collects scanning data without boundaries on moving platforms, then more environmental information is captured, but the map becomes corrupted and incompatible with centralized mapping systems
Solution Approach 1:
The patent applies local quality by creating a bounded local map that captures environmental information only within the moving platform's immediate vicinity. The scanning data collection is spatially constrained to the platform's local environment, preventing contamination of the global map while still providing sufficient information for accurate local tracking and hologram rendering.
3Manufacturing precision
If the MR system uses unbounded scanning data from moving platforms, then the local map contains more detailed information, but it cannot remain decoupled from the global map
Solution Approach 1:
The patent segments the scanning data collection into bounded local regions that follow the moving platform. This segmentation enables detailed local mapping within the platform's immediate environment while maintaining the independence of the global map. The bounded approach ensures that local map details do not compromise map independence.
4Duration of action of stationary object
If the MR system continuously tracks on moving platforms using the global map, then tracking continuity is maintained, but the system experiences map corruption and degraded performance
Solution Approach 1:
The patent implements a dynamic map switching system that adapts the tracking approach based on real-time detection of platform motion. When motion is detected, the system dynamically transitions from using the global map to using a local map, and vice versa when stationary. This dynamic adaptation maintains tracking continuity while preventing performance degradation.

AI summary
Techniques for enabling a library of local maps to remain de-coupled from a global map are disclosed. An MR system is determined to be located on a platform that is currently moving or that has an ability to readily move. That platform's type is determined. Based on the determined type for the platform, a 3D boundary that approximates a shape for the platform's type is generated. The 3D boundary is imposed on the platform. Scanning data for the platform is acquired. The bounds for that scanning data is at least initially limited to that of the 3D boundary. The scanning data is used to build or supplement a library of local maps. The library is representative of the platform. That library is prevented from being coupled to a global map.
