The controller is configured to obtain a first calibration matrix between the projector and the camera for the at least two elements; determine at least two epipolar lines based on the first calibration matrix and the test pattern image; determine a cost function based on the at least two epipolar lines and the at least two elements in the test pattern image as captured by the camera; and determine a second calibration matrix responsive to the cost function, wherein at least one of a camera position of the camera or a projector position of the projector is adjusted responsive to the second calibration matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calibration of camera and projector","description":"Described examples include a system including a projector configured to project a test pattern image, the test pattern image having at least two elements; a camera configured to capture the test patte","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11284050","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.
