Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality technologies struggle to efficiently recognize and interact with real-world objects, particularly 2D and 3D printed materials, without the need for hidden signatures or QR codes, limiting their ability to provide dynamic and updated digital overlays.
Innovation Solution
A system that uses image recognition techniques to identify and trigger digital overlays on real-world objects, allowing for the superimposition of virtual images, videos, and interactive content, without requiring hidden patterns or QR codes, and enables flexible definition of recognition areas, enabling real-time updates and recognition across various angles and lighting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional augmented reality technologies use hidden signatures or QR codes for object recognition, then recognition accuracy is improved, but device complexity and ease of operation deteriorate due to the need for hidden patterns or codes on printed materials
Solution Approach 1:
The patent extracts and removes the requirement for hidden signatures or QR codes from the printed materials. The system achieves object recognition by analyzing visual features of the printed content itself (text, images, layout) without needing separate recognition markers, thereby eliminating the complexity of embedding hidden patterns while maintaining recognition accuracy
Solution Approach 2:
The system creates a digital copy or representation of the printed material's visual features and uses this copy for recognition. By capturing and analyzing the visual appearance of the printed content directly, the system avoids the need for physical hidden markers, simplifying both the printed material and the recognition process
2Measurement precision
If augmented reality systems use fixed recognition areas, then measurement precision is improved, but adaptability deteriorates when objects are viewed from various angles or under different lighting conditions
Solution Approach 1:
The patent implements dynamic recognition areas that automatically adjust based on the captured image conditions. The system determines optimal recognition regions in real-time, adapting to different viewing angles, lighting conditions, and object orientations. This dynamic adjustment maintains high recognition precision across varied conditions without requiring fixed predetermined areas
Solution Approach 2:
The system changes key parameters of the recognition process including the size, position, and shape of recognition areas based on image analysis. By dynamically adjusting these parameters according to lighting conditions, angle of view, and detected feature distribution, the system maintains precision while gaining adaptability to diverse viewing scenarios
3Loss of information
If digital overlays are updated by creating new prints or codes, then content freshness is improved, but productivity and loss of time deteriorate due to the need for reprinting
Solution Approach 1:
The system performs preliminary actions by creating and storing multiple digital overlay versions in advance, linked to specific printed materials through the recognition system. When an update is needed, the system can immediately switch to a pre-prepared digital overlay without requiring physical reprinting, enabling rapid content updates while maintaining content freshness
Solution Approach 2:
The patent uses digital copying and replacement of overlay content rather than physical reprinting. The recognition system identifies the printed material and applies the appropriate digital overlay from a database, allowing instant updates by simply changing the digital content associated with the printed material, thereby eliminating reprinting time and improving productivity
