AR Display System Multi-User Camera Attitude Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems are unable to simultaneously overlay content on images taken by multiple users in real-time, especially in dynamic environments like sports stadiums, where accurate camera attitude estimation and content positioning are challenging due to symmetric markers and varying camera angles.
Innovation Solution
An augmented reality display system comprising a wide camera system, cloud server, and terminal device that produces and transmits position information of objects, estimates camera attitude using seven parameters, and overlays content on images based on transformed position information, allowing simultaneous overlay of useful content on images taken by multiple users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If augmented reality systems use traditional content overlay methods, then content can be displayed on individual images, but multiple users cannot simultaneously view personalized content from their respective perspectives
Solution Approach 1:
The system segments the content delivery process by creating separate data streams for each user device. Each terminal device receives customized position information and content data tailored to its specific camera attitude and user perspective, enabling personalized AR overlays without requiring complex inter-device coordination
Solution Approach 2:
The system introduces an intermediary server that acts as a mediator between the content source and multiple user devices. This server receives camera attitude information from each device, calculates transformed position information, and distributes appropriate content to each user, thereby managing multi-user personalization without increasing individual device complexity
2Measurement precision
If the system transforms position information based on camera attitude estimation, then accurate content positioning is achieved, but the processing time and computational load increase
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing transformation matrices and position information in a database before actual content overlay is needed. When a user views content, the system simply retrieves pre-computed data rather than performing real-time calculations, thereby maintaining high positioning accuracy while minimizing processing time
Solution Approach 2:
The system changes parameters by using pre-computed transformation matrices that capture camera attitude information. Instead of performing complex real-time coordinate transformations, the system retrieves and applies pre-calculated transformation parameters, significantly reducing computational load while maintaining positioning precision

AI summary
An augmented reality display system includes: a data producing system that produces position information of an object; a cloud server that receives the position information produced by the data producing system; and a terminal device connectable to the cloud server through a network. The terminal device includes: an imaging unit that produces an image data; a camera attitude estimating unit that estimates an attitude of the imaging unit from the image data; a data receiving unit that receives a content and the position information regarding the content from the cloud server; a data overlaying unit that transforms the position information correspondingly to the attitude of the imaging unit estimated by the camera attitude estimating unit, and overlays the content on the image data based on a reference position indicated by the transformed position information to obtain an overlay image data; and a display unit that displays the overlay image data.
