Scene Reconstruction from Omnidirectional Cameras

Popis výsledku v původním jazyce

We show that a very complete 3D metric reconstruction of the surrounding scene from two or more uncalibrated omnidirectional images can be obtained. We show that 3D metric reconstruction of the surrounding scene from two or more uncalibrated omnidirectional images can be performed very similarly as with standard perspective cameras. First, the omnidirectional camera is calibrated using image correspondences and epipolar constraint. Secondly, a projective factorization-based reconstruction from many images handling occlusions is used. Finally, an upgrade to a metric reconstruction is performed. The proposed linear estimation techniques give a good starting point for a non-linear bundle adjustment enforcing metric constraints on the reconstruction and including lens nonlinearity. We demonstrate our method in experiments with Nikon FC-E8, Sigma 8mm-f4-EX fish-eye lenses and non-cetral catadioptric cameras with a spherical, hyperbolic and parabolic mirror. Nevertheless, the proposed method
