The non-dyadic lens distortion correction method includes: (a) acquiring a non-dyadic lens image photographed through a non-dyadic lens; (b) correcting geometric distortion for the non-dyadic lens image by stage by applying a magnification ratio based on a projection model; and (c) compensating a high-frequency component of an image corrected in a previous step by the patch unit in the non-dyadic lens image of which the geometric distortion is corrected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-dyadic lens distortion correction method and apparatus","description":"Provided are a non-dyadic lens distortion correction method and an apparatus thereof.
