Abstract: In this paper a new method for conics based stereo vision was proposed. By using the new method for the detection of general quadric curves proposed by the authors, we investigated the global solutions of planar quadric curves and quadratic surfaces in the space and proposed a unified representation and solving algorithm. The main results about the multi-solutions are as follows: (1) if there exists solution of planar quadric curves then there exists solution of quadratic surfaces; (2) if and only if there are three views then there exists only one solution.
