What is LiDAR system? Know how this technology will benefit Railways

How LiDAR System Works: LiDAR, whose full name is “Light Detection and Ranging”, is a technology that estimates the exact distance and structure of any object with the help of a laser beam. This technique is used for identifying, mapping objects and preparing their 3D models. This technology is also being used especially in transportation, aerial survey, autonomous vehicles and railways, which improves accuracy and safety.

How does LiDAR system work?

In LiDAR system, rays of light come out from the laser, which collide with an object and reach back to the sensor. The distance of the object is determined by the time taken for this collision and return. Through this process, a high-resolution and detailed 3D map can be created, which provides deep information about the structure.

Use of LiDAR in Railways and its benefits

LiDAR technology is being used in Indian Railways for track survey, infrastructure monitoring and mapping. Through this technology, accurate information about the railway track and its surrounding area is obtained.

Accurate and detailed mapping

With the help of LiDAR, detailed 3D maps of railway tracks, bridges, tunnels and other structures can be prepared. This makes construction and maintenance work easier.

Structure monitoring and maintenance

Through LiDAR technology, the actual condition of the railway infrastructure can be detected, due to which wear and tear or any other problem can be easily identified. This system ensures timely repairs and maintenance.

The data obtained from LiDAR helps in protecting the railway network from natural disasters, as it provides accurate assessment of the area and can identify the places at risk.

Not only this, this system will also send information about defects, edge, blockage and broken tracks on the railway track to the control room. With this, accidents occurring in railways can be controlled. With the help of this technology, trains can be saved from accidents to a great extent.
