43 results about "Reprojection error" patented technology

The reprojection error is a geometric error corresponding to the image distance between a projected point and a measured one. It is used to quantify how closely an estimate of a 3D point recreates the point's true projection . More precisely, let be the projection matrix of a camera and be the image projection of , i.e. . The reprojection error of is given by , where denotes the Euclidean distance between the image points represented by vectors and .
