Abstract

The invention relates to a method for detecting rail transit tunnel bounding. The method realizes dynamic detection of subway tunnel bounding by using two-dimensional laser scanning, comprises data acquisition and preprocessing, and can effectively filter out noise interference; then carries out out-of-bounds judgment based on a prediction model, and carries out alarming when crosses the bounding.According to a novel prediction model, the prediction effect is better, the prediction precision is higher, and the technical scheme is complete and easy to integrate and program to realize.

Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to a method for detecting the boundary of rail transit tunnels. Background technique [0002] With the rapid development of China's rail transit construction, large-scale rail transit lines have been put into operation, and the derived rail transit safety issues have attracted much attention. The rail transit boundary is an important indicator to ensure the safe operation of vehicles in a specific space. Regular inspection of the boundary range is a necessary measure to reduce accidents and ensure the safety of rail transit operation. [0003] The traditional rail transit limit detection method is mainly based on manual inspection, and auxiliary tape measure, touch rod, total station and other equipment are used for detection. The speed is slow, the efficiency is low, the cost is high, and the technical requirements for operators are high, which has gradually failed to meet...
