Abstract
This research proposes a method for accurate all-round 3D reconstruction of an indoor environment in one-shot using a system of trinocular 360-degree cameras. Binocular 360-degree stereo is unable to reconstruct in all directions due to lack of disparity along epipolar directions. Thus, a third camera along a perpendicular epipolar direction is introduced to cover for this, making the system trinocular. However, previous works with trinocular stereo did not adequately take into account the uncertainty of disparity estimation and geometric constraints around 3D reconstruction. Therefore, we propose a geometric optimization scheme considering disparity estimation uncertainty and show that this results in both higher accuracy and lesser outliers along epipolar directions, in both simulated and real environments.
