【Abstract】 In this paper,the function and construction of a non-contact automatic measurement system for track parameters are introduced,and the principle for measuring each track parameter is discussed.At the same time,the principle of chord measurement and the inverse filter technology for measurement of track alignment and the track profile irregularities,the data processing method and the realization of inverse filter in the system were put forward.A large number of experimental results have showed that the measuring system has high availability and high accuracy compared with the manual measurement method.So it can completely meet with the demands of railway measurement spots.更多还原
