Conjugate Gradient Bundle Adjustment
Bundle adjustment for multi-view reconstruction is traditionally done using the Levenberg-Marquardt algorithm with a direct linear solver, which is computationally very expensive. An alternative to this approach is to apply the conjugate gradients algorithm in the inner loop. This is appealing since the main computational step of the CG algorithm involves only a simple matrix-vector multiplicat...
متن کاملBundle Adjustment using Conjugate Gradients with Multiscale Preconditioning
Bundle adjustment is a key component of almost any feature based 3D reconstruction system, used to compute accurate estimates of calibration parameters and structure and motion configurations. These problems tend to be very large, often involving thousands of variables. Thus, efficient optimization methods are crucial. The traditional Levenberg Marquardt algorithm with a direct sparse solver ca...
متن کاملBundle block adjustment of large-scale remote sensing data with Block-based Sparse Matrix Compression combined with Preconditioned Conjugate Gradient
In recent years, new platforms and sensors in photogrammetry, remote sensing and computer vision areas have become available, such as Unmanned Aircraft Vehicles (UAV), oblique camera systems, common digital cameras and even mobile phone cameras. Images collected by all these kinds of sensors could be used as remote sensing data sources. These sensors can obtain large-scale remote sensing data w...
متن کاملCombined Bundle Adjustment of Panoramic and Central Perspective Images
Based on a strict mathematical model for rotating line cameras developed at the Institute of Photogrammetry and Remote Sensing of the Dresden University of Technology, a self-calibrating bundle adjustment of panoramic image data was implemented. This model has been extended by the option to involve central perspective images of a conventional camera. A panoramic bundle adjustment is a suitable ...
متن کاملBundle adjustment using aerial images with two-stage geometric verification
In this paper, a new pipeline of Structure-from-Motion for ground-view images is proposed that uses feature points on an aerial image as references for removing accumulative errors. The challenge here is to design a method for discriminating correct matches from unreliable matches between ground-view images and an aerial image. If we depend on only local image features, it is not possible in pr...
