Embodiment Construction

[0046] For the sake of reference and clarity, the technical terms, abbreviations or abbreviations used below are recorded as follows:

[0047] Point cloud data: Scan data is recorded in the form of points, each point contains three-dimensional coordinates, some may contain color information (RGB) or reflection intensity information (Intensity); point cloud data not only has geometric positions, but also some have colors Information, color information is usually obtained through the camera to obtain color images, and then assign the color information (RGB) of the pixels at the corresponding positions to the corresponding points in the point cloud; the acquisition of intensity information is the echo intensity collected by the laser scanner receiving device. Intensity information is usually related to the surface material, roughness, incident angle and direction of the target, as well as the emitted energy of the instrument and the laser wavelength;

Abstract

The invention discloses a railway comprehensive inspection system. An attitude determination and positioning system acquires GNSS, IMU and DMI data of a comprehensive inspection vehicle, a laser radar acquires three-dimensional coordinates of a measured object, and a panoramic camera acquires panoramic image data. And the time-space synchronization system provides clock synchronization for the three-dimensional coordinates, the IMU, the DMI and the panoramic image data according to GNSS time service. And the storage/control system stores the three-dimensional coordinates, the IMU, the DMI and the panoramic image data after clock synchronization in real time. The point cloud processing system firstly uses GNSS, IMU and DMI data to fuse and calculate POS data, then uses the POS data and laser radar data to jointly calculate point cloud data, and carries out fusion processing on the point cloud and panoramic image data to obtain a real scene point cloud. And the comprehensive inspection analysis system performs railway infrastructure detection analysis by taking the point cloud and the panoramic image as a data source. The technical problems that an existing system is high in complexity and labor cost and large in data processing difficulty can be solved.

Description

technical field [0001] The invention relates to the technical field of railway engineering machinery, in particular to a comprehensive railway inspection system for railway line maintenance. Background technique [0002] With the rapid growth of my country's railway mileage, the inspection tasks of railway inspection, railway infrastructure and its components are becoming more and more heavy. In the past, railway inspections and infrastructure inspections were done by manual inspections or special equipment. Manual road patrol has high requirements on the quality of workers, high work intensity, and missed inspections due to easy distraction of people's attention. With the advancement of science and technology, the detection of railway infrastructure and its components has been gradually upgraded to specialized detection tools or operating vehicles. There are many types of railway infrastructure and its components, which directly lead to a large number of special inspectio...
