One "local" part involves the most recent keyframes and associated landmarks, and runs in constant time. This paper shows how representing landmarks and camera poses in relative frames, and by temporarily removing certain measurements, introduces a conditional indepedence which allows the bundle adjustment to be split into two parts. Unfortunately this monolithic bundle adjustment has cubic complexity. The landmark structure and keyframe poses are optimised in a bundle adjustment. Finally, we include a comparative evaluation of a large set of today's best-performing stereo algorithms.Ī successful approach in the recovery of video- rate structure from motion is to allow the camera to keep track of its position in every frame assuming the recovered set of scene landmarks is fixed in 3D, and then to use the poses in a subset of separated frames, or keyframes, to initialise further landmark structure.

We have also produced several new multi-frame stereo data sets with ground truth and are making both the code and data sets available on the Web.

In order to establish a common software platform and a collection of data sets for easy evaluation, we have designed a stand-alone, flexible C++ implementation that enables the evaluation of individual components and that can easily be extended to include new algorithms. Using this taxonomy, we compare existing stereo methods and present experiments evaluating the performance of many different variants. Our taxonomy is designed to assess the different components and design decisions made in individual stereo algorithms. In this paper, we present a taxonomy of dense, two-frame stereo methods. While a large number of algorithms for stereo correspondence have been developed, relatively little work has been done on characterizing their performance. Stereo matching is one of the most active research areas in computer vision. Experimental results on both indoor and outdoor sequences demonstrate the effectiveness and robustness of our method.

Finally, the labeling results are refined by a graph cuts based optimization method to enforce global smoothness. Then, a deterministic voxel coloring scheme carves away the voxels with large variance. First, a sparse set of surface points are utilized to initialize a subset of voxels. We propose a three-step voxel labeling method based on a robust photo-motion variance measure. The task of shape inference is then formulated as assigning each voxel a dynamic label which minimizes photo and motion variance between voxels and the original sequence. Each voxel is assigned a label at each time instant, either as empty, or belonging to background structure, or a moving object. The 3D scene is divided into a set of volume elements, termed as voxels, organized in an adaptive octree structure. We present a novel approach to inferring 3D volumetric shape of both moving objects and static background from video sequences shot by a moving camera, with the assumption that the objects move rigidly on a ground plane.
