This paper addresses an algorithm for simultaneous projective reconstruction of primitives, such as points, quadrics, planar conics, and degenerate quadrics by using bundle adjustment. One motivation for the use of quadric surfaces and plane conics is that many man-made objects are built up from them. We reconstruct each primitives by using their silhouettes, and we refine initial multiple cameras and all 3D primitives simultaneously through bundle adjustment. Due to the noise in the data, the global minimum of classic cost function used in bundle adjustment may unfortunately break the topology of the quadrics, planar conics and degenerate quadrics. Accordingly, during the iterations of this method, we need to add new constraints to keep the planar conic and degenerate quadric to preserve their topology. Finally, experiments performed on real data are given.
