Solution Approach 1:

The patent replaces manual mechanical measurement operations with an automated optical measurement system. The system uses an image collection device to capture grain flake images and an acquisition unit to automatically process these images through color segmentation and edge detection algorithms, eliminating the need for skilled workers to manually measure grain flakes while maintaining high measurement accuracy and significantly improving efficiency

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The measurement system is designed to autonomously perform the complete measurement process without human intervention. The acquisition unit automatically receives images, performs color segmentation in HSV space, conducts binary image edge segment topological structural analysis, calculates thickness values, and generates measurement results independently, making the system self-sufficient and eliminating dependence on skilled operators

Inventive Principle:
Principle #25Self-service

Solution Approach 1:

The patent transforms the measurement problem by changing the parameter space from direct thickness measurement to color space analysis. By converting images to HSV color space and performing color segmentation, the system extracts grain flake boundaries and thickness information indirectly through color characteristics, achieving high precision automated measurement. The use of multiple image processing parameters (color thresholds, edge detection parameters, topological features) enables accurate thickness calculation

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces intermediate processing steps between image capture and thickness measurement. Color segmentation in HSV space serves as an intermediary that separates grain flake regions from background, followed by binary image edge segment topological structural analysis that extracts boundary information. These intermediary processes enable the system to accurately determine thickness values from complex grain flake images, maintaining measurement precision while achieving full automation

Inventive Principle:
Principle #24Intermediary (Mediator)
