PANTOBOT is a full-fledged vision-based monitoring system for train pantographs inspection. At the core of the system is PAVISYS, a set of vision-based algorithms developed by the University of Parma in collaboration with Italian Railway Network (RFI). In the current implementation, when PAVISYS detects an image containing a damaged pantograph, throws an alarm to an operator in charge of supervision. The automatic inspection algorithm consists of three main steps: a pantograph classifier, a modular quality assessment system, and a report generator. The paper provides details about the module in charge of the classification step. The algorithm developed performs the classification both of the pantograph models and the material on the contact bars. An extensive set of results was obtained, and here reported, during the monitoring of the first installation of the system in operative conditions along a railway line. The very high measured levels of sensitivity and specificity prove the quality of the PANTOBOT system.
