AR Display System Using Mirror Copy for Marker Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing augmented reality (AR) content display systems require the manual placement, removal, and re-placement of guide information such as QR codes or AR markers on target objects, which is inconvenient and time-consuming.
Innovation Solution
An AR content display system that uses one or more processors to acquire feature points in a nearby region where guide information is pasted, associate the region with the AR content, and display the AR content without the need for physical placement of guide information by recognizing a real space marker, allowing for automatic detection and correction of misregistration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide information such as QR codes or AR markers is manually pasted on target objects for AR content display, then the AR content can be displayed, but the work trouble and time consumption increase due to repeated pasting, peeling, and re-pasting for each work
Solution Approach 1:
The patent uses a mirror to create a virtual copy of the guide information (QR code or AR marker) on the mirror surface instead of physically pasting it on the target object. The imaging device captures the mirror reflection, and the AR content is displayed based on the captured image, eliminating the need for manual pasting and peeling operations while maintaining AR display functionality
Solution Approach 2:
The mirror acts as an intermediary element between the guide information and the imaging device. Instead of directly imaging the guide information on the target object, the system images the mirror reflection, which contains the guide information. This intermediary approach allows the guide information to be displayed without physical contact with the target object, reducing work trouble
2Measurement precision
If guide information is physically placed on target objects to enable AR content display, then the AR content can be associated with the correct object, but the complexity of setup and misregistration correction increases
Solution Approach 1:
The mirror creates a virtual copy of the guide information that can be imaged without physical placement on the target object. The system captures the mirror reflection and processes it to identify the target object and associate AR content accordingly, reducing setup complexity while maintaining positioning accuracy through image processing
Solution Approach 2:
The patent replaces the mechanical process of physically pasting and positioning guide information on target objects with an optical system using a mirror and imaging device. The mechanical placement operations are substituted by capturing light reflections from the mirror, which automatically provides the guide information needed for AR content association without manual intervention

AI summary
An augmented reality (AR) content display system includes one or more processors configured to acquire feature points in a nearby region in which guide information for displaying an AR content is pasted, and display the region in which the feature points are acquired and the AR content in association with each other.
