Multi-Layered AR System Independent Virtual Object Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality technologies face challenges in independently controlling virtual objects on a screen, as they inevitably move within a single coordinate system and can disappear due to occlusion, limiting the ability to express complex interactions between objects.
Innovation Solution
A multi-layered augmented reality system that extracts and tracks target objects and backgrounds separately, applying different coordinate systems to virtual objects corresponding to each, allowing them to be displayed independently and interact freely, thereby preventing occlusion issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single coordinate system is used for all virtual objects, then the system complexity is reduced, but the virtual objects cannot move independently and interact freely
Solution Approach 1:
The patent divides the coordinate system into multiple independent layers: a first coordinate system for the target object and a second coordinate system for the background. This segmentation allows virtual objects to move independently within their respective coordinate systems while maintaining overall system manageability through clear separation of concerns.
2Reliability
If virtual objects are augmented based on a single coordinate system, then the implementation is simpler, but virtual objects disappear when feature points are covered due to occlusion
Solution Approach 1:
The patent segments the augmented reality scene into multiple layers with different coordinate systems. The first coordinate system tracks the target object independently, while the second coordinate system tracks the background independently. This segmentation ensures that occlusion of feature points in one layer does not affect the visibility and tracking of virtual objects in other layers.
3Adaptability or versatility
If multiple coordinate systems are applied to different virtual objects, then independent control and interaction are enabled, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by creating distinct coordinate system layers for different functional purposes: one layer for target object interaction and another for background reference. This segmentation enables sophisticated virtual object interactions while managing complexity through clear layer separation and independent transformation matrices for each coordinate system.
Solution Approach 2:
The patent adds a dimensional aspect to the coordinate system management by introducing multiple coordinate system layers rather than a single flat coordinate system. This dimensional change from one coordinate system to multiple nested coordinate systems enables independent virtual object control and interaction while providing a structured approach to managing the increased complexity.

AI summary
A multi-layered augmented reality system and method may extract a target object and a background from an image frame, may track the target object and the background, may apply different coordinate systems to a first virtual object corresponding to the target object and a second virtual object corresponding to the background, and may independently control the first virtual object and the second virtual object.
