Furthermore, a mapping matrix is determined based on the two 1×N matrices. The device then reads coordinates of base points designated in the reference image, and determines matching points in the real-time image based on the coordinates of base points and the mapping matrix. A reference region in the reference image is determined based on all the base points, and a matching region is determined in the real-time image based on all the matching points. The reference region and the matching region are compared to determine existence of any surface feature defects of the PCB."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image analysis device and method","description":"An image analysis device reads a reference image and a real-time image of a printed circuit board (PCB), determines feature points and feature information of the feature points in the reference image;","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8515156","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
