Generic and real-time structure from motion using local bundle adjustment
This paper describes a method for estimating the motion of a calibrated camera and the three dimensional geometry of the filmed environment. The only data used is video input. Interest points are tracked and matched between frames at video rate. Robust estimates of the camera motion are computed in real-time, key frames are selected to enable 3D reconstruction of the features. We introduce a lo...
متن کاملGeneric and Real-Time Structure from Motion
We introduce a generic and incremental Structure fromMotion method. By generic, we mean that the proposed method is independent of any specific camera model. During the incremental 3D reconstruction, parameters of 3D points and camera poses are refined simultaneously by a generic local bundle adjustment that minimizes an angular error between rays. This method has three main advantages: it is g...
متن کاملStructure-from-motion using lines: Representation, triangulation, and bundle adjustment
We address the problem of camera motion and 3D structure reconstruction from line correspondences across multiple views, from initialization to final bundle adjustment. One of the main difficulties when dealing with line features is their algebraic representation. First, we consider the triangulation problem. Based on Plücker coordinates to represent the 3D lines, we propose a maximum likelihoo...
متن کاملIncremental Motion Estimation Through Local Bundle Adjustment
We propose a new incremental motion estimation algorithm to deal with long image sequences. It applies to a sliding window of triplets of images, but unlike previous approaches, which rely on point matches across three or more views, we also use those points shared only by two views. This is important because matches between two views are more common than those across more views. The problem is...
متن کاملIncremental light bundle adjustment for structure from motion and robotics
Bundle adjustment (BA) is essential in many robotics and structurefrom-motion applications. In robotics, often a bundle adjustment solution is desired to be available incrementally as new poses and 3D points are observed. Similarly in batch structure from motion, cameras are typically added incrementally to allow good initializations. Current incremental BA methods quickly become computationall...
