Query: Structure from Motion for Panorama-Style Videos   We present a novel Structure from Motion pipeline that is capable of
reconstructing accurate camera poses for panorama-style video capture without
prior camera intrinsic calibration. While panorama-style capture is common and
convenient, previous reconstruction methods fail to obtain accurate
reconstructions due to the rotation-dominant motion and small baseline between
views. Our method is built on the assumption that the camera motion
approximately corresponds to motion on a sphere, and we introduce three novel
relative pose methods to estimate the fundamental matrix and camera distortion
for spherical motion. These solvers are efficient and robust, and provide an
excellent initialization for bundle adjustment. A soft prior on the camera
poses is used to discourage large deviations from the spherical motion
assumption when performing bundle adjustment, which allows cameras to remain
properly constrained for optimization in the absence of well-triangulated 3D
points. To validate the effectiveness of the proposed method we evaluate our
approach on both synthetic and real-world data, and demonstrate that camera
poses are accurate enough for multiview stereo.
