AR Data Stream Segmentation for Processing Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an effective method and apparatus to manage and process data to support Augmented Reality (AR) applications, particularly in handling image file data that includes scene description, object descriptors, and visual streams to overlay virtual content onto real-world environments.
Innovation Solution
A method and apparatus that receive an image file with a scene description stream, object descriptor stream, and visual stream, extract information from AR nodes to determine when and how to augment the real-world medium with AR content, and access elementary streams to output the augmented real-world medium, utilizing a processor and display to integrate virtual objects into the real environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If AR content is integrated into image file data structures, then AR functionality and information completeness are improved, but data processing complexity and system requirements increase
Solution Approach 1:
The patent segments AR data into distinct streams including scene description stream, object descriptor stream, and visual stream. Each stream handles specific aspects of AR content separately, allowing independent processing and reducing overall system complexity while maintaining complete AR functionality.
Solution Approach 2:
The patent introduces an AR node as an intermediary element within the scene description stream that connects real-world visual content with virtual AR content. This intermediary structure facilitates the integration of AR information without requiring complete reorganization of the entire data processing system.
2Manufacturing precision
If multiple streams (scene description, object descriptor, visual) are processed simultaneously, then AR content accuracy and synchronization are improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary processing of scene description and object descriptor streams separately before final integration with visual content. By preparing AR data elements in advance and organizing them into structured formats, the system reduces real-time processing requirements and improves synchronization accuracy during actual AR rendering.

AI summary
A method and apparatus of processing data to support Augmented Reality (AR) are provided. In the method, an image file including at least a scene description stream, an object descriptor stream, and a visual stream including a real-world medium is received, the scene description stream including an AR node that represents information about at least one piece of AR content used to augment the real-world medium, information about an AR locator and an object descriptor Identifier (ID) is acquired from the AR node, the AR locator describing when the at least one piece of AR content appears and how the real-world medium is augmented with the at least one piece of AR content and the object indicator ID identifying an Object Descriptor (OD) that describes the at least one piece of AR content, and at least one elementary stream descriptor.
