Abstract

This work shows an example of a methodology which could be followed to process a crossing geometry with the objective of obtaining and evaluating planar sections. Primitive geometry is reached by profilometry techniques as point cloud geometry and then preprocessed with simple filtering in order to clean it from noise and outliers. Variable geometry on railway crossings requires methods to be then applied in different zones for checking if any local refinement is necessary. Lastly, sections are postprocessed, obtaining an intelligible contour curve to be afterwards visually inspected or as a profile source for multibody software.
