This webinar will provide an overview of an ongoing FRA R&D project which involves the development of railway asset change detection technology using a combination of 3D laser scanning and Artificial Intelligence. The presentation will include a discussion of the project site (the TTCI High Tonnage Loop), field data collection and data processing. Details of the technology used to capture 3D scans will be shared along with details of the AI including training and data processing. Preliminary results from the project will be shared including data related to fasteners, joints and ballast.
