INSPECTION APPARATUS, INSPECTION METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18324217 titled 'INSPECTION APPARATUS, INSPECTION METHOD, AND STORAGE MEDIUM
Simplified Explanation
The patent application describes a method to prevent errors in inspection by suppressing a failure in position adjustment using non-linear transformation. Here is a simplified explanation of the abstract:
- The method aims to prevent errors in inspection by ensuring accurate position adjustment between an inspection image and a reference image.
- Initially, position adjustment is performed using linear transformation between the inspection image (obtained by reading a printed material) and the reference image.
- However, in certain cases where a specific condition is met, further position adjustment is performed using non-linear transformation for the inspection image.
- The purpose of this additional non-linear transformation is to improve the accuracy of the position adjustment and reduce the occurrence of erroneous inspections.
Potential Applications:
- Quality control in manufacturing: This method can be applied in industries where accurate inspection of printed materials is crucial, such as packaging, labeling, and printing industries.
- Document verification: It can be used to verify the authenticity and accuracy of printed documents, such as passports, identification cards, and certificates.
Problems Solved:
- Error reduction: The method addresses the problem of erroneous inspections caused by inaccurate position adjustment between inspection and reference images.
- Improved accuracy: By incorporating non-linear transformation, the method aims to enhance the precision of position adjustment, reducing the chances of false positives or negatives in inspections.
Benefits:
- Increased efficiency: By preventing errors and reducing the need for re-inspection, the method can improve overall inspection efficiency.
- Enhanced quality control: Accurate position adjustment ensures that defects or discrepancies in printed materials are reliably detected, improving the quality control process.
Original Abstract Submitted
The occurrence of an erroneous inspection is suppressed by preventing a failure of position adjustment by non-linear transformation. In position adjustment between an inspection image obtained by reading a printed material and a reference image, after performing position adjustment by linear transformation, only in a case where a certain condition is satisfied, position adjustment by non-linear transformation is further performed for the inspection image for which the position adjustment by linear transformation has been performed.
