Fabric type identifying apparatus and fabric type identifying method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fabric identification methods in laundry factories face challenges in accurately identifying fabric types due to stretching and shrinking, leading to unstable identification, especially when fabrics have similar dimensions.
Innovation Solution
A fabric type identifying apparatus that uses a camera and image processing to acquire the color value of a color thread attached to the fabric's edge, with a traversing device to adjust the camera's position for high-resolution photography, allowing for accurate identification regardless of fabric dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fabric type identification is performed based on dimensional information (length and thickness), then identification can be performed using existing measurement methods, but identification accuracy deteriorates when fabrics undergo stretching and shrinking or when different fabrics have similar dimensions
Solution Approach 1:
The invention extracts the color thread from the fabric as a separate identification feature. By focusing measurement on the color thread's color value rather than the fabric's dimensional properties, the system isolates a stable characteristic that doesn't change with stretching or shrinking, thereby resolving the contradiction between measurement capability and identification reliability
Solution Approach 2:
The invention utilizes color as the primary identification parameter by measuring the color value of the color thread. Different fabric types are represented by different color threads, and the camera-based color measurement system captures these color differences accurately. This approach transforms the identification basis from unstable dimensional measurements to stable color measurements, achieving high accuracy regardless of fabric dimensional changes
2Measurement precision
If a camera is positioned to photograph the entire fabric, then complete fabric information can be captured, but the color thread at the edge portion cannot be photographed with sufficient resolution for accurate color identification
Solution Approach 1:
The invention extracts only the necessary information (color value of the color thread) rather than capturing the entire fabric. The camera is positioned and configured to photograph only the edge portion containing the color thread, eliminating the need for full-fabric coverage while achieving the identification goal with higher precision
Solution Approach 2:
The invention applies different photographing strategies to different parts of the fabric. The camera is specifically positioned to capture the edge portion with high resolution for color thread identification, while other parts of the fabric are not photographed. This localised approach optimizes measurement precision for the critical identification feature without requiring complete fabric coverage

AI summary
To provide a fabric type identifying apparatus and a fabric type identifying method enabling to stably identify a type of fabric with high accuracy. A fabric type identifying apparatus A for identifying a type of a fabric F provided with a color thread T at an edge portion includes a camera 51 for photographing the fabric F, and an image processing apparatus 52 for receiving an image input and photographed by the camera 51. The image processing apparatus 52 acquires a color value of the color thread T from the received image of the fabric F, and identifies the type of the fabric F on a basis of the color value. Since the type of the fabric F is identified on the basis of the color of the color thread T, the type of the fabric F is enabled to be stably identified with high accuracy regardless of stretching and shrinking of the fabric F.
