It is required to measure the distance between the moving carriage and int rusive foreign objects or the carriage ahead during shunting operation s. The traditional solutions for distance measurement include laser and radar distance measur ement methods , while more and more studies about the binoc ular visi on system come up .
For laser distance measur ement methods , one dimensional rangefinder is feasible for the objects in a straight line ahead ; however, the scanning laser rangefinder cannot distinguish whether the objects ahead are on the railway track. Limited by the measurement accuracy resulting from camera installation on board , the binocular vision system [ is not suitable for measuring the distance of intrusive objects on tracks
as well. In this paper, a monocular vision syst embased on special designed image pre processing algorithm is presented, which will accurately recognize and locate the railway track s and objects on track s. Moreover, this system could calculate the distance between the carriage with camera and the objects detected.
