Abstract :
Presents a stereo vision method based on quadric curves. Different to the previous curve based stereo method in which curves in images are used for computing the features of the points and for establishing the point-point correspondence between the left and the right image, the authors provide a closed form solution for the global matching criterion of two quadric curves in two images and furthermore, a closed form solution for the global reconstruction of the conics in the scene. It is shown that the matching of two quadric curves can be established globally and the reconstruction can be performed by solving three one variable quadric equations. The algorithm can be implemented in real time
