Photometric bundle adjustment
Bundle adjustment. A sparse matrix obtained when solving a modestly sized bundle adjustment problem. This is the arrowhead sparsity pattern of a 992×992 normal-equation (i.e. approximate Hessian) matrix. Black regions correspond to nonzero blocks. In photogrammetry and computer stereo vision, bundle … See more In photogrammetry and computer stereo vision, bundle adjustment is simultaneous refining of the 3D coordinates describing the scene geometry, the parameters of the relative motion, and the optical characteristics of … See more Bundle adjustment is almost always used as the last step of every feature-based 3D reconstruction algorithm. It amounts to an optimization problem on the 3D structure and viewing parameters (i.e., camera pose and possibly intrinsic calibration and radial distortion), to obtain … See more • Adjustment of observations • Stereoscopy • Levenberg–Marquardt algorithm • Sparse matrix • Collinearity equation See more Software • [1]: Apero/MicMac, a free open source photogrammetric software.

Multi-view 2D–3D alignment with hybrid bundle adjustment for visual metrology Article Webrely on bundle adjustment to jointly optimize the keyframe poses and the map points [9, 17, 40, 48]. Recently, in [11, 65], it was suggested that decoupling the rotation es-timation through rotation averaging improves the efficiency and the handling of pure rotations. Bundle adjustment is mainly classified into geometric and photometric methods.
