The method includes providing an image of the face; identifying the characteristic points on the image of the face; identifying shape points on the image of the face; identifying the shape of the face from among predefined characteristic shapes using the shape points; determining from the characteristic points a frame of reference for receiving the surface of the spectacle frame; and determining the height position and width of the end pieces relative to the surface of the spectacle frame depending on the face shape identified."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for preparing a spectacle frame","description":"A method for preparing a spectacle frame (1) adapted to a face, the spectacle frame (1) having a bridge (11) between two optical lenses (9-10) and a surface (2) having end pieces (5-6) to which temple","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9589340","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.
