Description

technical field

[0001] The present invention relates to a track geometric state measurement system and method, in particular to a track geometric state measurement system and method based on multi-source information fusion technology. Background technique

[0002] High-speed railway is the development trend of railway transportation in the world today. With the construction and operation of large-scale passenger dedicated lines in my country, higher requirements are put forward for railway tracks. The accurate geometry of the railway track is the most basic condition to ensure the safe operation of the train. Only a high and smooth track can ensure the high-speed and safe operation of the train. For this reason, in addition to special requirements for the design and construction of railway engineering and track engineering, a complete, efficient and accurate engineering measurement system must be established. The track precision control network has been established during ...
