Defect Inspection Imaging With ROI Marking Overlay Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional defect inspection apparatuses suffer from user-dependent inspection results due to the need for manual identification of regions of interest, leading to inconsistencies in defect detection.
Innovation Solution
A defect inspection apparatus with an imager that superimposes a marking on a predetermined region of interest in the image display, ensuring consistent positioning of the marking regardless of the user, thereby standardizing the inspection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual identification of regions of interest is used, then user flexibility is maintained, but inspection result consistency deteriorates
Solution Approach 1:
The patent uses template images that are copied and overlaid onto inspection results. These templates represent pre-defined regions of interest that can be automatically applied across multiple inspections, eliminating the need for manual re-identification while maintaining consistency. The template copying approach allows standardized defect detection across different users and inspection sessions.
2Reliability
If automatic marking superimposition is implemented, then inspection result consistency is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-defining templates that represent regions of interest before the actual inspection process. These templates are created in advance and stored for automatic retrieval and superimposition during inspection. This preliminary preparation eliminates the need for complex real-time processing during inspection, reducing operational complexity while maintaining consistency.
Solution Approach 2:
The patent introduces templates as an intermediary element between the inspection system and the defect detection process. These templates serve as mediators that standardize the identification of regions of interest, simplifying the interaction between users and the inspection system while ensuring consistent results across different inspections.
3Adaptability or versatility
If user-dependent defect identification is used, then adaptability to different inspection scenarios is maintained, but measurement precision deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the inspection process into distinct components: template creation, template storage, template retrieval, and template superimposition. This segmentation allows the system to handle different inspection scenarios through appropriate template selection while maintaining precise and consistent defect detection through standardized template application.

AI summary
A defect inspection apparatus (100) includes an imager (image sensor 35) configured to image an inspection target 7, and a display (6) configured to display an image based on an image captured by the imager. The defect inspection apparatus (100) also includes a controller (4) configured or programmed to receive a setting of a marking (64) in a predetermined region of interest (S) on the image (still image 61) displayed on the display (6). The controller (4) is configured or programmed to inspect the inspection target (7) for a defect based on the image captured by the imager, and superimpose an image of the marking (64) on a position corresponding to the predetermined region of interest (S) in an image of an inspection result (overlay image 65) displayed on the display (6).
