Photometric bundle adjustment

WebApr 8, 2024 · We use Ceres Solver to perform the photometric bundle adjustment. In addition to the standard installation process, we generate a custom template specialization corresponding to our Schur structure, which speeds up the Schur elimination step. This is an optional step that can be skipped. WebAug 26, 2024 · This work presents a framework for jointly optimizing millions of scene points and hundreds of camera poses and intrinsics, using a photometric cost that is invariant to local lighting changes. The improvement in metric reconstruction accuracy that it confers over feature-based bundle adjustment is demonstrated on the large-scale …
