On Reconstruction of Revolution

In the process of reconstruction of textured 3D models of revolution from images,the precise 3D shape of the revolution must be obtained in advance.This can be done using computer vision technique and from symmetry property of potteries.The problem of recovering the 3D shape of a surface of revolution from images is addressed.The algorithm makes use of the symmetry properties of a surface of revolution and its silhouette to rectify the image such that the resulting silhouette exhibits bilateral symmetry.The revolution axis of the surface of revolution is calculated by image parameters and top circle of revolution.The rectified image is then used to recover the contour generator and the object is reconstructed.Experimental results on real images are presented,which demonstrate the effectiveness of the approach.
