The present paper describes a concept for an onboard system specially designed for surveillance of catenaries of railways in front of trains. Damages to pantographs caused by defects or obstacles in catenaries will be avoided by such a system by retracting the pantograph in time. The special situation of this application is discussed. An overview of the(More)
The present paper describes the concept and first results of a system, capable to detect obstacles in catenaries as an onboard tool. To avoid a damage of the pantograph it must be retracted immediately after an obstacle is detected. The presented system is based on a triocular camera sensor system combined with smart image processing routines. The present(More)
Automobiles and railway vehicles have their specific safety standards, respectively. Still, they are both land vehicles and thus share a large set of common hazards and accident types. This calls for a common safety ontology covering both domains. Apart from many commonalities, we found some important differences between safety standards of these domains,(More)
