3D room layout estimation by a single panorama using deep neural networks has made great progress.
… previous approaches can not obtain efficient geometry awareness of room layout with the only latitude of boundaries or horizon-depth.
… present that using horizon-depth along with room height can obtain omnidirectional-geometry awareness of room layout in both horizontal and vertical directions.
… propose a planar-geometry aware loss function with normals and gradients of normals to supervise the planeness of walls and turning of corners.
… propose an efficient network, LGT-Net, for room layout estimation, which contains a novel Transformer architecture called SWG Transformer to model geometry relations.
… LGT-Net achieves better performance than current state-of-the-arts (SOTA) on benchmark datasets.
