Embodiment Construction

[0025] The principles and features of the present invention will be described below in conjunction with the accompanying drawings and specific embodiments. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0026] Such as figure 1 and figure 2 As shown, the present invention provides a rail close-range laser scanning measurement device, including a positioning target 3, a laser scanner 1, a running car 2 and a server. There are multiple positioning targets 3 and are correspondingly installed on the CPIII signs on both sides of the track. The marks are evenly distributed on both sides of the track, the CPIII mark is correspondingly provided with a metal sleeve 5, and the positioning target 3 is provided with coordinates to determine the specific position of the track. Disconnect the connection. The running trolley 2 is detachably installed with a column 4. The laser scanner 1 adopts a 360° pan...

Abstract

The invention relates to a rail close range laser scanning measuring device. The rail close range laser scanning measuring device comprises positioning targets, a laser scanner, a running trolley anda server, wherein a plurality of positioning targets are correspondingly arranged on CPIII marks on two sides of a rail; the laser scanner is arranged on the running trolley; the running trolley is arranged on the rail and can move along the rail; the laser scanner scans photographs rails and positioning targets on two sides and collects point cloud data and pictures; and the laser scanner is connected with a server through wireless signals. The invention also provides a measuring method on the basis of the measuring device, and the measuring method mainly utilizes the laser scanner to rapidlymeasure the rails. The measuring device provided by the invention has the beneficial effects that the structure is simple, workers do not need to further process measurement data, the data feedback is quick and intuitive, the measurement is accurate, and original data can be provided for the construction of engineering projects and the establishment of a BIM model for operation management and maintenance.

Description

technical field [0001] The invention relates to the technical field of high-speed railway track measurement, in particular to a track close-range laser scanning measurement device and method. Background technique [0002] Railway track is an important basic equipment that directly supports the smooth operation of high-speed trains. When designing track routes, technicians need to do a lot of on-the-spot investigation and measurement work, so as to plan the preset route of the track and ensure the safe operation of the train. Track construction on the preset route is an important guarantee for the safe operation of high-speed trains in the later stage. However, in the process of track construction, due to various factors, the built track deviates from the preset track route, so real-time measurement of the built track is required. , to ensure the safe operation of the track. [0003] The traditional track detection technology is based on the detection system of the total sta...
