AR Embroidery Display Device Marker Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack effective methods for determining and displaying embroidery patterns with respect to sewing workpieces using augmented reality (AR) technology, which hinders precise arrangement and visualization of embroidery designs.
Innovation Solution
A non-transitory computer-readable storage medium and an embroidery pattern displaying device that detects markers in real images captured by a camera, using AR technology to superimpose embroidery pattern images onto the real image, allowing users to visualize and edit the pattern arrangement with respect to the sewing workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If AR technology is used to display embroidery patterns on sewing workpieces, then visualization accuracy and arrangement precision are improved, but device complexity increases due to the need for marker detection and image processing systems
Solution Approach 1:
A marker is introduced as an intermediary object to facilitate the AR display process. The marker serves as a reference for detecting the workpiece position and orientation, enabling accurate pattern superposition without requiring complex direct workpiece analysis. The marker detection unit specifically targets this intermediary element to simplify the overall system approach.
Solution Approach 2:
The embroidery pattern is displayed as a virtual copy superimposed on the real workpiece image. The pattern image is generated based on detected marker information and displayed through the displaying unit, creating a visual copy that allows users to preview the embroidery result before actual stitching occurs.
2Manufacturing precision
If marker-based AR superposition is implemented, then pattern arrangement accuracy is improved, but processing time increases due to real-time image capture and marker detection requirements
Solution Approach 1:
The marker is prepared and attached to the workpiece before the AR display process begins. This preliminary action ensures that the marker detection unit can immediately locate the reference point when the image is captured, eliminating the need for complex real-time workpiece feature recognition and reducing processing time.
Solution Approach 2:
The marker utilizes distinct visual characteristics (such as color or pattern) that make it easily distinguishable from the workpiece background. This allows the marker detection unit to quickly identify and lock onto the marker without extensive image processing, thereby reducing the time required for accurate pattern placement.

AI summary
A non-transitory computer-readable medium stores computer-readable instructions. The instructions, when executed, cause a processor of an embroidery pattern displaying device provided with a capturing portion and a displaying portion to perform steps. The steps include detecting a marker associated with an embroidery pattern arranged within an augmented reality space from a real image that is an image of a real space captured by the capturing portion. The steps include displaying, when the marker is detected from the real image, a pattern image indicating the embroidery pattern associated with the detected marker, superimposed on the real image with the detected marker as a reference, on the displaying portion.
