The concept of utilizing iTwin Capture Modeler in the design of railway infrastructure

Abstract: The paper investigates the feasibility of utilizing iTwin Capture Modeler software, which is designed for generating 3D models from photogrammetric data, in the design of railway infrastructure. Basing on general requirements of photogrammetric data acquisition and previous micro scale analysis, the methodology was developed. The study presents the results of an analysis of an existing double slip on straight tracks located in Koscierzyna Railway Museum. The generated 3D model allowed to determine the geometric layout of the analysed crossing. Keywords: Project; Railway track; Photogrammetry; Digital twins
