The paracatadioptric projection of a 3D line is a conic. In this paper, the constraint relation of three conics formed by three 3D lines according to the paracatadioptric projection is divided into three situations. In the first, three groups of vanishing points in orthogonal directions are formed by the principle point coordinates and six intersection points of the three conics. In the second, six groups of vanishing points in orthogonal directions are determined by common diameters on the unit sphere and tangents at intersection points of the three conics. In the third, three groups of circular points are formed by each side of a complete quadrangle formed by two circular points and the intersection points of the three conics. These three methods can solve the camera intrinsic parameters effectively and accurately, as verified by simulation and real data applications.
