View Interpolation along a Chain of Weakly Calibrated Cameras

This paper presents an algorithm for interpolating intermediate views along a chain of cameras. There is no restriction on the camera placement as long as the distance between successive cameras is not too large. The interpolated views lie on a virtual poly-line defined by the (ordered) set of cameras. Our algorithm requires no strong camera calibration as the necessary epipolar geometry is estimated from the input images itself. The algorithm first runs a preprocessing step to rectify the images to canonical epipolar geometry and to calculate disparity images. The actual view interpolation uses this data to synthesize intermediate views in real-time.
