An e cient algorithm to accurately estimate depth and occluded points from two or more uncalibrated views is presented. The basic concept is to apply a dynamic programming technique for displacement estimation, after estimating the exact positions of two corresponding epipolar lines. The ultimate goal is to be able to automatically generate accurate 3-D models from two or more views of a scene ...

This paper presents a method to continuously adjust the parallax in 3D-TV visualization. It is based on a generic framework for novel view synthesis from two uncalibrated reference views that allows to move a virtual camera along a path that is obtained starting from the epipolar geometry of the reference views. The scene is described by its relative affine structure from which novel views are ...

Image-based rendering is a method to synthesize novel views from a set of given real images. This contribution describes two methods to extrapolate novel views of complex scenes with occlusions and large depth discontinuities from images of a moving uncalibrated multi-camera rig. The real camera viewpoints are calibrated from the image data and dense depth maps are estimated for each real view....

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 est...

ÐWe present a new function that operates on Fundamental matrices across a sequence of views. The operation, we call athreadingo, connects two consecutive Fundamental matrices using the trifocal tensor as the connecting thread. The threading operation guarantees that consecutive camera matrices are consistent with a unique 3D model, without ever recovering a 3D model. Applications include recove...

Many machine vision tasks, e.g. object recognition and object inspection, cannot be performed robustly from a single image. For certain tasks (e.g. 3D object recognition and automated inspection) the availability of multiple views of an object is a requirement. This paper presents a novel approach to selecting a minimised number of views that allow each object face to be adequately viewed accor...

A method for the automatic reconstruction of 3D objects from multiple camera views for 3D multimedia applications is presented. Conventional 3D reconstruction techniques use equipment that restrict the flexibility of the user. In order to increase this flexibility, the presented method is characterized by a simple measurement environment, that consists of a new calibration pattern placed below ...

In the proposed method, the relative depth of the objects present in a 3D scene is calculated, using 2D images captured from a camera placed on a rotating platform. Unlike the conventional stereo imaging system, the proposed method captures multiple views of a 3D scene, each view taken at a different camera positions while on the rotating platform. The approach adapted calculates the disparity ...

This paper presents an image rectification method for an arbitrary number of views with aligned camera center. This paper also describes how to extend this method to easily perform a robust camera calibration. These two techniques can be used for stereoscopic rendering to enhance the perception comfort or for depth from stereo. In this paper, we first expose why epipolar geometry is not suited ...

We describe a new method for Structure From Motion from three affine views. The central idea of the method is to explore the intrinsic three-view properties instead of previous two-view ones. The first key observation is that an affine camera is indeed essentially a one-dimensional projective camera operating on the plane at infinity : we prove that the essential motion—relative camera orientat...
