Abstract

A train inspection system includes a camera interface configured to receive a sequence of inspection image frames of a moving train captured by a static camera. The inspection system further includes a processor system configured to receive sequences of inspection image frames from the camera interface. The inspection system further includes a communication interface configured to output results from the processor system. The inspection system further includes a database coupled to the processor system and storing a model which allows a sequence of image frames of a moving train to be evaluated for departures from normalcy. The inspection system further includes program storage coupled to the processor system and storing computer program instructions for execution by the processor system. The computer program instructions, when executed by the processor system: image analyse the sequence of inspection image frames to allocate image frames to locations along the length of the train; use the model to identify locations on the moving train where the sequence of inspection image frames indicates departures from normalcy passing a threshold value; and output the identified locations and the corresponding departures from normalcy at the communication interface as predicted anomalies.
