SYSTEM AND METHOD FOR DETERMINING SPATIAL POSITION AND ALIGNMENT OF RAILWAY TRACK, LASER MEASURING DEVICE FOR COLLECTING DATA ON ACTUAL POSITION OF TRACK Russian patent published in 2023 - IPC B61K9/08 E01B29/04 E01B35/00 G01C3/00 

FIELD: railway engineering.

SUBSTANCE: systems for determining the position of railway tracks and carrying out engineering work. The system for determining the spatial position and alignment of the railway track includes system for collecting geospatial data about the existing track position, data processing system, machine control system for track alignment, an additional system for collecting data about the current position of the track, connected to a laser measurement device. According to the method for determining the spatial position and alignment of a railway track, geopositioning of track equipment is carried out using data from a locally organized permanent core network and using a satellite navigation system, field data on the location of the adjacent track superstructure infrastructure is received from a laser scanning system, data is processed, geometric recognition of rails images and identification of infrastructure objects in scanner data of laser reflection points and the recorded trajectory of track equipment is performed, the geometric axes of rails in space are determined, a geospatial model of infrastructure objects and track axes are constructed, track parameters are determined, the distances between the axes of the repaired and adjacent track and /or infrastructure objects taking into account the project are calculated, a program task is formed and transferred to the machine control system for straightening the track, repairs are carried out and the track in the design position is put.

EFFECT: manufacturability, safety and efficiency of processes aimed at straightening the railway track are increased, and automation of the process of operational control is achieved.
