This paper proposes a new approach for automated floorplan reconstruction
from RGBD scans, a major milestone in indoor mapping research. The approach,
dubbed Floor-SP, formulates a novel optimization problem, where room-wise
coordinate descent sequentially solves dynamic programming to optimize the
floorplan graph structure. The objective function consists of data terms guided
by deep neural networks, consistency terms encouraging adjacent rooms to share
corners and walls, and the model complexity term. The approach does not require
corner/edge detection with thresholds, unlike most other methods. We have
evaluated our system on production-quality RGBD scans of 527 apartments or
houses, including many units with non-Manhattan structures. Qualitative and
quantitative evaluations demonstrate a significant performance boost over the
current state-of-the-art. Please refer to our project website
