WebMay 1, 2007 · Camera resectioning is frequently utilized in frame-sampling based structure and motion analysis ( Fitzgibbon and Zisserman, 1998, Nister, 2001, Georgescu and Meer, 2002 ), and off-line video-based augmented reality ( Gibson et al., 2002, Seo et al., 2003, Kim and Hong, 2004 ). Camera resectioning is the process of estimating the parameters of a pinhole camera model approximating the camera that produced a given photograph or video; it determines which incoming light ray is associated with each pixel on the resulting image. Basically, the process determines the pose of the … See more The camera projection matrix is derived from the intrinsic and extrinsic parameters of the camera, and is often represented by the series of transformations; e.g., a matrix of camera intrinsic parameters, a 3 × 3 rotation matrix, … See more • 3D pose estimation • Augmented reality • Augmented virtuality • Eight-point algorithm • Mixed reality See more There are many different approaches to calculate the intrinsic and extrinsic parameters for a specific camera setup.
