The Algorithm Research On Freight Train Gauge Monitoring System Based On Digital Image Processing

The threats of the security of raiIway freight mostly come from cargoes exceeding over the railway gauge which caused by loading, collision, braking and shaking etc. Today, the loading situation is most Iy checked manua My, wh i ch can on Iy check the Ioad i ng s i tuat i on of the static freight train with the low efficiency and precision. The automat i c mon i tor i ng on the I oad i ng s i tuat i on of mov i ng f re i ght tra i ns should be implemented to ensure the operation security of railway fre i ght.The paper presents a new algorithm for freight train image segmentation with the aim of minimizing missing gauge-exceeding detection rate based on the image segmentation theory. The prof i le of the freight train and cargoes on the image is obtained with the arithmetic and whether cargoes exceeding the gauge or not is concluded by the location of the freight train and cargoes on the image. The algorithm is verified by images of moving freight train. It is proved that the algorithm has good adaptability, acceptable precision and satisfied processing speed in normal climate.
