The Canadian Surveyor, 1980
The characteristic features of programs for the block adjustment of bundles are described in the context of their historical development, and the approach used in the program developed by the author at the National Research Council of Canada is explained. This is followed by a more detailed account of the latter program.

Bundle Adjustment in the Large
2010We present the design and implementation of a new inexact Newton type algorithm for solving large-scale bundle adjustment problems with tens of thousands of images. We explore the use of Conjugate Gradients for calculating the Newton step and its performance as a function of some simple and computationally efficient preconditioners.

Depth-based sparse bundle adjustment
Applied Optics, 2022It is demonstrated in this paper that due to error model inconsistency, a certain degree of accuracy loss would be incurred to the estimated parameters when the traditional bundle adjustment method is directly applied to the scenario where a fraction of observations is implicitly error free (e.g., the reference image points in commonly used least ...

Angle Independent Bundle Adjustment Refinement
Third International Symposium on 3D Data Processing, Visualization, and Transmission (3DPVT'06), 2006Obtaining a digital model of a real-world 3D scene is a challenging task pursued by computer vision and computer graphics. Given an initial approximate 3D model, a popular refinement process is to perform a bundle adjustment of the estimated camera position, camera orientation, and scene points.

Robust Bundle Adjustment Revisited
2014In this work we address robust estimation in the bundle adjustment procedure. Typically, bundle adjustment is not solved via a generic optimization algorithm, but usually cast as a nonlinear least-squares problem instance. In order to handle gross outliers in bundle adjustment the least-squares formulation must be robustified.

Algebraic Line Search for Bundle Adjustment
Procedings of the British Machine Vision Conference 2009, 2009Bundle Adjustment is based on nonlinear least squares minimization techniques, such as Levenberg-Marquardt and Gauss-Newton. It iteratively computes local parameter increments. Line Search techniques aim at providing an efficient magnitude for these increments, called the step length. In this paper, a new ad hoc Line Search technique for solving bundle
