OmniDepth: Dense Depth Estimation for
Indoors Spherical Panoramas.
Abstract. Recent work on depth estimation up to now has only focused
on projective images ignoring 360o
content which is now increasingly and
more easily produced. We show that monocular depth estimation models trained on traditional images produce sub-optimal results on omnidirectional images, showcasing the need for training directly on 360o
datasets, which however, are hard to acquire. In this work, we circumvent
the challenges associated with acquiring high quality 360o datasets with
ground truth depth annotations, by re-using recently released large scale
3D datasets and re-purposing them to 360o
via rendering. This dataset,
which is considerably larger than similar projective datasets, is publicly
offered to the community to enable future research in this direction. We
use this dataset to learn in an end-to-end fashion the task of depth estimation from 360o
images. We show promising results in our synthesized
data as well as in unseen realistic images
