Continuous Extraction of Subway Tunnel Cross Sections Based on Terrestrial Point Clouds

Continuous Extraction of Subway Tunnel Cross Sections Based on Terrestrial Point Clouds

An efficient method for the continuous extraction of subway tunnel cross sections using terrestrial point clouds is proposed. First, the continuous central axis of the tunnel is extracted using a 2D projection of the point cloud and curve fitting using the RANSAC (RANdom SAmple Consensus) algorithm,...
