In the field of computer vision, any two images of the same planar surface in space are related by a homography (assuming a pinhole camera model). This has many practical applications, such as image rectification, image registration, or camera motion—rotation and translation—between two images. Once camera resectioning has been done from an estimated homography matrix, this information may be used for navigation, or to insert models of 3D objects into an image or video, so that they are rendered with the correct perspective and appear to have been part of the original scene (see Augmented reality). (en) Inom området för datorseende är två bilder från samma plana yta relaterade genom en homografi (förutsatt en hålkameramodell). Detta har flera användningsområden, som t.ex. bildrektifiering, bildregistrering, panoramabilder, eller beräkning av kamerarörelse - rotation och translation - mellan två bilder. När kamerans rotation och translation har extraherats från en estimerad homografi-matris kan informationen användas för navigation eller t.ex. modeller av 3D objekt i en bild eller video så att de kan renderas med korrekt perspektiv och se ut att vara en del av scenen; förstärkt verklighet. Figuren visar en kamera som tittar på planet på avståndet d. (sv) |
