Stranded Wire Image Segmentation for Consistent Pattern Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection methods for stranded wires often misjudge normal wires as abnormal due to variations in image patterns across divided images.
Innovation Solution
An information processing device that acquires and processes images of stranded wires to detect the length for dividing them into the same pattern, using geometric transformation and similarity level calculations or Fourier transform to ensure consistent pattern alignment.

1Productivity
If an image of a stranded wire is divided into rectangular regions for inspection, then the inspection process becomes automated and efficient, but the pattern of the stranded wire may differ across divided images causing normal wires to be misjudged as abnormal
Solution Approach 1:
The patent applies preliminary action by detecting the length for acquiring images of the stranded wire in the same pattern before performing the actual inspection. This pre-detection step ensures that when the image is subsequently divided into rectangular regions, each region contains consistent pattern information, preventing misjudgment of normal wires as abnormal while maintaining automated inspection efficiency
Solution Approach 2:
The patent changes the parameter of image division length based on the detected length for acquiring images of the stranded wire in the same pattern. By adjusting this parameter, the system ensures that divided images maintain pattern consistency, resolving the contradiction between automated inspection efficiency and measurement precision
