Abstract

A flexible new camera calibration technique using 2D-DLT and bundle adjustment with planar scenes is proposed in this paper. The equation of principal line under image coordinate system represented with 2D-DLT parameters is educed using the correspondence between collinearity equations and 2D-DLT. A novel algorithm to obtain the initial value of principal point is put forward in this paper. The practical decomposition algorithm of exterior parameters using initial values of principal point, focal length and 2D-DLT parameters is discussed elaborately. Planar-scene camera calibration algorithm with bundle adjustment is addressed. For the proposed technique, either the camera or the planar pattern can be moved freely, and the motion need not be known. Very good results have been obtained with real data calibration. The calibration result can be used in some high precision applications, such as reverse engineering and industrial inspection.
