Technical News Office –Whose full name is “Light Detection and Ranging”, is a technology that estimates the exact distance and structure of any object using a laser beam. This technology makes it possible to identify objects, map them and prepare 3D models. This technology is also used in transport, aerial surveys, autonomous vehicles and railways, improving accuracy and safety.
How does the LiDAR system work?
In the LiDAR system, the laser emits rays of light that collide with an object and return to the sensor. The distance of the object is determined by the time it takes for this collision and return. Through this process, a detailed, high-resolution 3D map can be produced, which provides detailed information about the structure.
Use of LiDAR in railways and its advantages
LiDAR technology is used by Indian Railways for track surveying, infrastructure monitoring and mapping. Using this technology, precise information about the railway track and its surroundings is obtained.
Precise and detailed mapping
With the help of LiDAR, detailed 3D maps of railway tracks, bridges, tunnels and other structures can be prepared. This facilitates construction and maintenance work.
Monitoring and maintenance of works
Using LiDAR technology, the actual condition of the railway infrastructure can be detected, so that wear or any other problems can be easily identified. This system ensures timely repairs and maintenance. Data obtained from LiDAR helps protect the rail network from natural disasters because it accurately assesses the area and identifies risky locations. In addition, this system will also send information about defects, age, blockage and broken tracks on the railway track to the control room. This will help in controlling railway accidents. At the same time, thanks to this technology, trains can be largely saved from accidents.
