Embodiment Construction

[0082] The present invention will be described in detail below in combination with specific embodiments.

[0083] refer to figure 1 , the present invention is based on a high-precision vehicle-mounted mobile measurement system, a method for investigating track asset ledgers, comprising the following steps:

[0084] 1) Collect field data: RMMS high-precision vehicle-mounted mobile measurement system collects point cloud data and navigation data along the railway. The collected data includes setting up base stations to collect GPS base station data, and using RMMS high-precision vehicle-mounted mobile measurement system to collect 3D laser point cloud data, DMI data (encoder data), DMR data (inertial navigation data) and GPS data.

[0085] 2) Solve and fuse point cloud data

[0086] In the step 2), it is necessary to perform dead reckoning according to the principle of integrated navigation first, and calculate the POS trajectory data, and then fuse the point cloud data and th...

Abstract

The invention relates to a ballastless track asset standing book investigation method based on a high-precision vehicle-mounted mobile measurement system. The method comprises the steps of field datacollection, fusion point cloud data calculation, line laser data calculation, point cloud data and line laser data superposition display, semi-automatic track board addition, track board parameter information automatic extraction, track board automatic numbering, data inspection, data editing and result data output. The key problems of automation and rapid measurement result output of a high-precision vehicle-mounted mobile measurement system which is a new technology in the existing line asset standing book investigation and management process can be solved.

Description

technical field [0001] The invention relates to the technical field of high-speed rail construction and operation, in particular to a method for investigating track asset ledgers based on a high-precision vehicle-mounted mobile measurement system. Background technique [0002] By 2020, my country's railway operating mileage will reach more than 120,000 km, including 16,000 km of high-speed railways. It is undoubtedly a huge project to carry out the investigation and management of asset ledgers for these existing lines. At present, relevant railway departments adopt the traditional manual investigation operation method for management, which has the disadvantages of low efficiency and cumbersome personnel management and training. How to use the existing new Technology-assisted high-speed rail track asset ledger investigation has also become a hot spot that needs to be studied urgently. [0003] Three-dimensional laser scanning technology, also known as "real scene replication...
