METHODS FOR POSITIONING POINTS OR LINES OF INTEREST ON THE RAILWAY, POSITIONING AND CONTROL OF THE MACHINE FOR INTERVENTION ON THE RAILWAY Russian patent published in 2022 - IPC B61L23/04 

FIELD: railway transport.

SUBSTANCE: invention relates to means of maintenance and monitoring of the railway track. Method for determining the location of points or lines (A, B, C, D) of interest on a railway track (22) by means of a railway track positioning system (12) comprising a linear camera (26) and an odometer (28) moving along the railway track (22 ) in the advancing direction (100), the odometer (28) repeatedly collects instantaneous position data of the line camera (26) relative to the railway track (22) in the advancing direction (100), and the line camera (26) directed at the railway track (22) repeatedly collects instantaneous linear optical data along the line (50) of the instantaneous measurement. Then, by processing at least instantaneous linear optical data and instantaneous positioning data, a bitmap image of the area of ​​the surface of the railway track (22) is built, and at least one spatial indexing marker (56) of a predetermined characteristic and its position relative to the support rail are identified on this bitmap image. (22A) railway track (22). Points or lines (A, B, C, D) of interest are identified on the raster image, and the coordinates of these points or lines of interest are determined in the two-dimensional system O, x, y of the location reference associated with the spatial indexing marker (56) and the reference line (22A).

EFFECT: increased accuracy and lead time of determining the locations of points or lines of interest on the railway track.
