CD Spring 2018 - Reality Modelling into Operational Training (Track Access)
1 like197 views
Track Access Services Ltd provides digital services for rail, including reality modelling using video, laser scanning, and 3D modelling. They capture driver's eye video and positional data to create interactive models for route familiarization, signal sighting, and reviewing design changes. By integrating video, point clouds, and CAD data, their models provide visual context to help evaluate designs and make decisions without site visits. The accurate 3D models are used for engineering, simulation and training to reduce the need for building multiple versions.
