Printed Image AR Content Positioning Across Variable Media Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in accurately displaying augmented reality content on a display screen due to variations in the size of the medium on which an image is printed, leading to misalignment of the content with the printed marker.
Innovation Solution
A content provision system that includes a processor for setting a target image, storing associated content, transmitting printing data, receiving a read image, specifying the storage destination, and transmitting display data to align the content with the printed image on the display screen, considering the size and position of the printed medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the content is displayed at a position decided with a marker of the printed matter as a reference, then the content can be displayed on the display screen, but the content may not be appropriately displayed when the size of the medium is not appropriate due to changes in relative position between the printed matter and the marker
Solution Approach 1:
The system changes the parameter of reference from a fixed marker position to a flexible combination of printed matter image and marker position. By detecting the printed matter image and calculating the marker's relative position dynamically, the system adapts to different medium sizes and maintains accurate content alignment regardless of printing variations.
Solution Approach 2:
The system creates a digital copy of the printed matter image through image detection and uses this copy to calculate the marker's relative position. This digital replica allows the system to determine the correct content display position without being constrained by physical medium size variations, enabling accurate positioning across different print formats.
2Device complexity
If a marker is used as a reference for content display, then content positioning is simplified, but the system becomes sensitive to size variations of the printing medium
Solution Approach 1:
The system achieves universality by making the content positioning method applicable to multiple medium sizes and formats. Instead of requiring different markers or positioning methods for different paper sizes, the system uses a unified approach that detects the printed matter image and calculates marker positions relative to it, making the positioning system adaptable to various printing conditions without increasing complexity.
3Manufacturing precision
If the relative position between printed matter and marker changes due to medium size variations, then content alignment is compromised, but maintaining fixed marker positioning reduces flexibility
Solution Approach 1:
The system transitions from a static marker positioning approach to a dynamic one where the marker's relative position is calculated based on the detected printed matter image. This dynamic calculation allows the system to adapt to different medium sizes and maintain accurate content alignment, as the positioning is determined at runtime rather than being fixed during content creation.
