From Planes to Corners: Multi-Purpose Primitive Detection in Unorganized 3D Point Clouds by C. Sommer, Y. Sun, L. Guibas, D. Cremers and T. Birdal, published in IEEE Robotics and Automation Letters (RA-L) 2020 and presented at the International Conference on Robotics and Automation (ICRA) 2020. Paper: https://arxiv.org/abs/2001.07360 Code: https://github.com/c-sommer/orthogona... Abstract: We propose a new method for segmentation-free joint estimation of orthogonal planes, their intersection lines, relationship graph and corners lying at the intersection of three orthogonal planes. Such unified scene exploration under orthogonality allows for multitudes of applications such as semantic plane detection or local and global scan alignment, which in turn can aid robot localization or grasping tasks. Our two-stage pipeline involves a rough yet joint estimation of orthogonal planes followed by a subsequent joint refinement of plane parameters respecting their orthogonality relations. We form a graph of these primitives, paving the way to the extraction of further reliable features: lines and corners. Our experiments demonstrate the validity of our approach in numerous scenarios from wall detection to 6D tracking, both on synthetic and real data.
