The paper studies planar surface reconstruction of indoor scenes from two
views with unknown camera poses. While prior approaches have successfully
created object-centric reconstructions of many scenes, they fail to exploit
other structures, such as planes, which are typically the dominant components
of indoor scenes. In this paper, we reconstruct planar surfaces from multiple
views, while jointly estimating camera pose. Our experiments demonstrate that
our method is able to advance the state of the art of reconstruction from
sparse views, on challenging scenes from Matterport3D. Project site:

Planar Surface Reconstruction from Sparse Views

Access to large, diverse RGB-D datasets is critical for training RGB-D scene
understanding algorithms. However, existing datasets still cover only a limited
number of views or a restricted scale of spaces. In this paper, we introduce
Matterport3D, a large-scale RGB-D dataset containing 10,800 panoramic views
from 194,400 RGB-D images of 90 building-scale scenes. Annotations are provided
with surface reconstructions, camera poses, and 2D and 3D semantic
segmentations. The precise global alignment and comprehensive, diverse
panoramic set of views over entire buildings enable a variety of supervised and
self-supervised computer vision tasks, including keypoint matching, view
overlap prediction, normal prediction from color, semantic segmentation, and
region classification.
