Imagine a scenario in which trains can “see” their environment, much like how humans do with eyes. This isn’t science fiction in the world of railways; it’s a reality made feasible by two amazing technologies: 3D Perception and LIDAR. To put it simply, 3D Perception is the equivalent of giving trains the capability to see the environment in three dimensions and LIDAR is like the magic eye of the train which uses laser beams to measure distances and provide a thorough map of the area. In this blog, we’ll look at how these technologies combine to make trains safer and more intelligent and will discover how they operate on the rails, see any issues, and discover why they’re preferred to alternative approaches.
Railways are extensive networks, so it is important to ensure both passenger and freight safety while ensuring seamless operation. Tracks, signals, and barriers have historically been monitored by railways using a variety of techniques. However, the introduction of 3D Perception, particularly by LIDAR, has revolutionized how railways sense and react to their surroundings.
3D Perception – What Is It?
Giving robots the capacity to see the environment in three dimensions, as humans can with our eyes, is what is meant by “3D Perception.” It’s crucial to comprehend not just what is present but also how far away objects are and how they seem in three dimensions. In contexts as dynamic as railways, this skill is essential.
LIDAR in the Railways
The function of LIDAR in railway will now be discussed in more detail. The term “LIDAR” involves a technique that uses laser beams to estimate distances with extreme accuracy. LIDAR sensors are used in railways to provide a real-time, three-dimensional image of the environment on trains, trackside infrastructure, or maintenance vehicles.
How the LIDAR Railway Works with 3D Perception
Similar to a torch lighting a dark room, LIDAR sensors produce laser beams that travel in various directions. These laser beams reflect off things, such as a rail that is out of alignment or a tree limb that is too close to the rails. The LIDAR sensor determines the distance to these objects by timing how long it takes the laser beams to return.
