Railway locomotive and vehicle operating attitude measurement system

A railway locomotive and vehicle operating attitude measurement system comprises a group of high-speed video cameras which are installed on at least three non-colinear points of a tested vehicle body,arranged oppositely to a running track of the tested vehicle body and used for shooting a track image sequence when a train runs, and an imagine acquisition and processing module used for receiving the track image sequence and analyzing the track image sequence obtained by the high-speed video camera on each point so as to obtain offset of each point relative to the track and determine a spatialattitude and the offset of the tested vehicle relative to two tracks. The railway locomotive and vehicle operating attitude measurement system takes rail surface and track center line as a benchmark,and is non-contact and based on machine vision, can conduct real-time measurement to the dynamic offset of the locative and vehicle to obtain the dynamic offset of an optional position on the vehiclebody relative to track surface coordinates, conduct online measurement to the vehicle dynamic displacement in real time, conduct early warning and alarm to overrunning, and simultaneously ensure the measurement accuracy.
