The invention relates to a railway track abrasion detection method and
system, and aims to realize accurate and efficient detection of turnout
sharp point rail abrasion. A detection device carrying a 3D camera, a speed sensor, a
signal processing module and a
data processing terminal is arranged in a turnout area to be detected, parameter configuration is completed, in the constant-speed moving process, the speed sensor generates a trigger
signal according to the specified distance, the 3D camera is driven to synchronously collect
point cloud data of the two-dimensional contour of the cross section of the
sharp point rail, and a three-dimensional
data stream is formed; after data are denoised, section registration splicing and three-dimensional
model reconstruction are completed in combination with distance stamps, an actual measurement model and a standard contour model are superposed and compared, abrasion parameters are calculated, and the maximum abrasion point and position are recognized; and finally presenting the abrasion data in the forms of a color cloud picture, a table and the like, and automatically generating a standard detection report containing the contents of line information, defect types and the like. According to the method,
automation and
visualization of abrasion detection are achieved, the detection precision is high, the efficiency is high, and reliable data support is provided for track maintenance.
