摘      要：Railway departments in various countries are looking for a technology with convenient operation,low price,excellent measurement performance and stability for spatial position measurement of railway ***,we design an optic-electronics stereo system based on the principle of optical stereo *** experimental verification in the real railway environment shows that the performance of the system is that the longitudinal relative displacement measurement range is 200—10000 mm,the relative distance measurement range is 4500 mm and the measured root mean square(RMS)error value is less than 1.1 mm in the whole ***,it meets the relevant needs of the Russian Ministry of railways.
