Abstract

Rigid 3D objects were modelled automatically from an image sequence taken by a camera that was rotated around the object. The image sequence was recorded using a calibrated camera which allows one to measure the camera positions and to estimate the true object size. The 3D object shape was obtained in two steps. The object silhouettes were employed to find the enclosing volume of the object. The volume was converted into a flexible surface representation and the 3D shape was refined based on the texture information of the object surface. Texture mapping was applied to generate a highly realistic 3D model of the object
