| Abstract: | Point Clouds are increasingly utilised for purposes requiring object modelling and the creation of a 3D representation. Using LiDar sensors, the Dutch company "Strukton" is scanning railroad rails in order to simplify their inspection process with the aim to move to digitalization. A previous research was able to create a data pipeline that accepts a point cloud as input and produces a 3D CAD model as output. Using this already-implemented data pipeline, this project aims to optimise its procedures, rework it so that it may be utilised for the whole catenary arches of railways, and ultimately automate it completely. The pipeline works with two main processes - segmentation and object retrieval. This research focuses on modifying the RANSAC sampling and fine alignment processes from [21] and explores techniques for CAD placement to achieve a fully automated data pipeline. |
