\chapter{Bundle
Adjustment
}
4
One of the main reasons for writing Ceres was our need to solve large scale bundle
adjustment
problems~\cite{hartley-zisserman-book-2004,triggs-etal-1999}.
6
Given a set of measured image feature locations and correspondences, the goal of bundle
adjustment
is to find 3D point positions and camera parameters that minimize the reprojection error. This optimization problem is usually formulated as a non-linear least squares problem, where the error is the squared $L_2$ norm of the difference between the observed feature location and the projection of the corresponding 3D point on the image plane of the camera. Ceres has extensive support for solving bundle
adjustment
problems.
69
Given this functor, the bundle
adjustment
problem can be constructed as follows:
71
// Create residuals for each observation in the bundle
adjustment
problem. The
89
Again note that that the problem construction for bundle
adjustment
is very similar to the curve fitting example.
91
One way to solve this problem is to set \texttt{Solver::Options::linear\_solver\_type} to \texttt{SPARSE\_NORMAL\_CHOLESKY} and call \texttt{Solve}. And while this is a reasonable thing to do, bundle
adjustment
problems have a special sparsity structure that can be exploited to solve them much more efficiently. Ceres provides three specialized solvers (collectively known as Schur based solvers) for this task. The example code uses the simplest of them \texttt{DENSE\_SCHUR}.
101
For a more sophisticated bundle
adjustment
example which demonstrates the use of Ceres' more advanced features including its various linear solvers, robust loss functions and local parameterizations see \texttt{examples/bundle\_adjuster.cc}.
