Traffic visualization method and system for high speed railway tunnel construction

Abstract

A traffic visualization method and system for high speed railway tunnel construction is disclosed in the present invention, falling within the technical field of tunnel construction positioning. The method includes the following steps: collecting, based on a current construction vehicle, real-time three-dimensional (3D) point cloud data, and sending the real-time 3D point cloud data to an ultra-wide band (UWB) base station; acquiring, based on the UWB base station, real-time distance data and uploading the real-time distance data and the real-time 3D point cloud data to a cloud data center; constructing, based on the cloud data center, a real-time high speed railway tunnel 3D map model; performing obstacle recognition according to the real-time 3D point cloud data, obtaining a real-time obstacle object, and highlighting the real-time obstacle object in the real-time high speed railway tunnel 3D map model; acquiring real-time positioning data of the current construction vehicle according to the real-time distance data; and highlighting the current construction vehicle in the real-time high speed railway tunnel 3D map model. The present invention solves the problems of large cost investment, and poor real-time performance, positioning accuracy and visualization effect existing in the prior art.
