Abstract: In order to locate points or lines of interest (A, B, C, D, A?, B?, C?, D?, 162, 163, 164) of a railway track (22), by means of a railway locating system (12), progressing on the railway track (22), a linear camera (26) pointing at the railway track (22) repeatedly acquires instantaneous linear optical data along an instantaneous measurement line (50), and an orientation device (52) of the railway locating system (12) repeatedly acquires orientation data of the railway locating system (12) with respect to a reference line (22A) of the railway track (22).

Abstract: In order to position a set of one or more tools supported by a railway intervention vehicle progressing on a railway track, data is received characterising a curvilinear abscissa of a spatial indexation marker, a positioning of the spatial indexation marker with respect to a reference line of the railway track, and coordinates of points or lines of interest in a two-dimensional reference system. Transposition matrix cameras acquire transposition bitmap images in a spatial reference system of the transposition system. An odometer acquires progression data of the transposition system. Then the spatial indexation marker is identified as a function of the progression data and curvilinear abscissa data, to determine data characteristic of the spatial indexation marker and the reference line in the spatial reference system of the transposition chassis, and to calculate transposed coordinates of the points or lines of interest.

Abstract: In order to position a set of one or more tools supported by a railway intervention vehicle progressing on a railway track (22), data is received characterising a curvilinear abscissa of a spatial indexation marker (56) of known signature, and a positioning of the spatial indexation marker (56) with respect to a reference line (122A, 122B, 222) of the railway track (22), and coordinates of points or lines of interest (A, B, C, D, A?, B?, C?, D?, 162, 163, 164) in a two-dimensional locating reference system linked to the spatial indexation marker (56) and to the reference line (122A, 122B, 222), one or more transposition matrix cameras (44) acquire a set of one or more transposition bitmap images in a spatial reference system of the transposition system (16), fixed with respect to the transposition chassis (45), and an odometer (28) acquires progression data of the transposition system with respect to the railway track (22).

Abstract: In order to locate points or lines of interest A, B, C, D on a railway track 22, by means of a railway locating system 12 comprising a linear camera 26 and an odometer 28 progressing on the railway track 22 in a direction of progression 100, the odometer 28, repeatedly acquires instantaneous positioning data of the linear camera 26 with respect to the railway track 22 in the direction of progression 100, and the linear camera 26 pointing at the railway track 22 repeatedly acquires instantaneous linear optical data along an instantaneous measurement line 50. Then, by processing at least the instantaneous linear optical data and the instantaneous positioning data, a bitmap image is constructed of a zone of the surface of the railway track 22, and, in the bitmap image, at least one spatial indexing marker 56 of predetermined signature and its positioning relative to a reference rail 22A of the railway track 22 is identified.
