UNCALIBRATED VIDEO CAMERAS Nelson L. Chang and Avideh Zakhor Department of Electrical Engineering and Computer Sciences University of California, Berkeley, CA 94720 USA e-mail: [email protected], [email protected] ABSTRACT This paper focuses on the representation and arbitrary view generation of three dimensional (3-D) scenes. In contrast to existing methods that construct a full 3-D model or those that exploit geometric invariants, our representation consists of dense depth maps at several preselected viewpoints from an image sequence. Furthermore, instead of using multiple calibrated stationary cameras or range data, we derive our depth maps from image sequences captured by an uncalibrated camera. We propose an adaptive matching algorithm which assigns various con dence levels to di erent regions. Nonuniform bicubic spline interpolation is then used to ll in low con dence regions in the depth maps. Once the depth maps are computed at preselected viewpoints, the intensity and depth at these locations are used to reconstruct arbitrary views of the 3-D scene. Experimental results are presented to verify our approach.

متن کاملView Synthesis of Scenes with Man-Made Objects Using Uncalibrated Cameras
We propose a scheme for view synthesis of scenes containing man-made objects from images taken by arbitrary, uncalibrated cameras. Under the assumption of availability of the correspondence of three vanishing points,in general position, our scheme computes z-buffer values that can be used for handling occlusions in the synthesized view. This requires the computation of the infinite homography. ...
متن کاملPhotoBuilder - 3D Models of Architectural Scenes from Uncalibrated Images
We address the problem of recovering 3D models from uncalibrated images of architectural scenes. We propose a simple, geometrically intuitive method which exploits the strong rigidity constraints of parallelism and orthogonality present in indoor and outdoor architectural scenes. We show how these simple constraints can be used to calibrate the cameras and to recover the projection matrices for...
