Framework for extracting rails and setting-out railway line axis based on UAV photogrammetric measurements

Technical diagnostics enables assessing the current technical condition of a railway line and adjacent infrastructure, and to forecast its changes over a specific time horizon. One of its elements is the periodic monitoring of rail position and their geometry. The data set presents a new framework for the setting-out of a railway track axis. The process in details is presented in the manuscript at the same title and is based on the specific filtration and extraction of rails from a point cloud originating from the photogrammetric process. Data was acquired using a small unmanned aerial vehicle (UAV). The data set provides full source code in Matlab.
