Then, it made full use of the theory of harmonic conjugate in projective geometry to calculate the inner parameters of camera.

然后充分利用射影几何调和共轭的理论求取摄像机的内参数。

Two pairs of vanishing points of orthogonal directions from each image are obtained by using the concept of cross ratio and harmonic conjugate in projective geometry and the orthogonal property of the two diagonals on a square. All intrinsic parameters are calculated linearly after capturing the template from at least three shooting angles. Errors of edge detection and line fitting are avoided because the method does not require image matching.
