Abstract
DLT (direct linear transformation) is one of the most popular methods of data simplification for camera calibration. An improved DLT method is proposed, the projective pseudo-inverse matrix is used to describe the relations between 2D coordinates and 3D coordinates, the improved DLT method can calculate the projective pseudo-inverse matrix based on only 4 known pixel points. The experiment results show that the proposed method is more efficient and more lightly limited by the prerequisites than traditional one, so it can be widely used in practice.
