Reconstruction of Interior Walls from Point Cloud Data with Min-Hashed J-Linkage

摘要

The automatic reconstruction of the walls of an interior environment is a fundamental task in any "scan2BIM" application. In this work, we address this problem resorting to an original and improved version of J-Linkage that leverages on the min-Hash technique to boost the efficiency without sacrificing the accuracy. A framework to automatically and robustly extract floor plans from large-scale point clouds is described and validated on real-word publicly available data.
