AR Image Projection Using Visual Markers for Canvas Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) systems struggle to accurately stabilize the detection of the plane and dimensions of a physical canvas for precise projection of digital images, making it difficult for users to effectively copy source images onto the canvas using physical media.
Innovation Solution
An AR-enabled computing application, referred to as an image copying assistant, detects markers such as QR codes to calculate the plane and boundaries of the physical canvas, aligning a digital canvas with the physical canvas for precise image projection and copying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If AR systems use camera-based detection to identify the physical canvas, then the system can recognize the canvas presence, but the detection of plane and dimensions becomes unstable and imprecise
Solution Approach 1:
The patent introduces visual markers (such as QR codes or distinctive patterns) as intermediary elements placed on the physical canvas. These markers serve as reliable reference points that the AR system detects and tracks to accurately determine the canvas plane and dimensions. The markers act as mediators between the physical canvas and the digital AR representation, enabling precise alignment and stable detection throughout the AR experience.
2Ease of operation
If the AR system overlays digital content on the camera view, then augmented reality is achieved, but accurate alignment with the physical canvas is difficult to maintain
Solution Approach 1:
The system continuously tracks the visual markers on the physical canvas and adjusts the digital canvas representation in real-time based on marker position and orientation feedback. This feedback mechanism ensures that the digital canvas remains accurately aligned with the physical canvas even when the user moves or changes perspective, making the image copying task easy and precise.
Solution Approach 2:
Visual markers serve as intermediary reference points that bridge the physical and digital representations. By detecting and tracking these markers, the system maintains accurate alignment between the physical canvas and its digital counterpart, enabling precise overlay of digital content and accurate image copying.
3Measurement precision
If the system detects markers to calculate canvas plane, then alignment accuracy improves, but the system complexity increases
Solution Approach 1:
The patent uses simple visual markers (such as QR codes or distinctive patterns) that can be easily replicated and placed on the physical canvas. These markers are computationally simple to detect and process, providing accurate alignment information without requiring complex detection algorithms or hardware. The markers copy essential alignment information in a format that is easy for the AR system to process.

AI summary
A system and method for displaying images on a digital display of a computing device in such a way that the images appear to be projected onto a physical space defined by visual markers in the physical environment. This involves using a digital image sensor of the computing device to detect one or more visual markers and determine a position and boundaries to display the image on the digital display of the computing device so that the images appear to be projected onto the designated space in the physical environment. The system and method also include interactive features that allow users to adjust the properties of the displayed images.
