The second processor matches features of interest in the selected video frame and captured image to correct the projector alignment. The images may be compared using blob detection or corner detection. Unlike prior art ‘off-line’ calibration methods, video frames can be processed continuously (e.g. every frame) or intermittently (e.g. every 10th frame) without interrupting the display of video content."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for projector alignment using detected image features","description":"A method and apparatus are provided for calibrating projector alignment using detected image features projected onto a surface, the apparatus comprising a first processor detects features in a single ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11303864","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.
