Engineering Contradiction Analysis
1Measurement precision
If an operator manually selects an image processing algorithm from multiple extracted algorithms, then the selection process allows human judgment and flexibility, but it consumes time and labor while potentially failing to select the optimal algorithm
Solution Approach 1:
The system performs preliminary evaluation of multiple image processing algorithms using evaluation images before actual inspection. The evaluation unit pre-assesses detection accuracy for each algorithm, and the setting unit pre-selects the optimal algorithm, so that when inspection is needed, the best algorithm is already ready without requiring manual selection during operation.
Solution Approach 2:
The inspection apparatus performs self-evaluation and self-selection of the optimal image processing algorithm. The evaluation unit automatically assesses detection accuracy by processing evaluation images through multiple algorithms, and the setting unit automatically selects and sets the algorithm with the highest evaluation result, eliminating the need for operator intervention in the selection process.
2Reliability
If multiple image processing algorithms are extracted and displayed for operator selection, then the system provides choices based on foreign-matter detection characteristics, but the manual selection process reduces productivity and may not achieve optimal detection
Solution Approach 1:
The inspection apparatus performs self-evaluation and self-selection of the optimal image processing algorithm. The evaluation unit automatically assesses detection accuracy by processing evaluation images through multiple algorithms, and the setting unit automatically selects and sets the algorithm with the highest evaluation result, eliminating the need for operator intervention in the selection process.
Solution Approach 2:
The system uses evaluation images to assess the detection accuracy of each image processing algorithm and feeds back this evaluation information to automatically determine the optimal algorithm. This feedback mechanism ensures that the algorithm with the highest detected foreign matter accuracy is selected, improving both reliability and productivity by eliminating manual selection.
3Productivity
If the system automatically evaluates and sets the optimal image processing algorithm, then selection time is reduced and productivity increases, but the system requires additional components for evaluation and automatic setting
Solution Approach 1:
The evaluation unit and setting unit serve multiple functions: they evaluate detection accuracy using test pieces, assess multiple algorithms simultaneously, and automatically select the optimal algorithm for future inspections. This multi-functionality justifies the added components by providing comprehensive algorithm management capabilities that improve overall system productivity.
