Objective of the Project

The objective of this project is to develop an obstacle detection system using Light Detection and Ranging (LiDAR) Optical technology

LiDAR is a remote sensing technology that uses laser beams to measure distances and create precise three-dimensional maps

Using this technology, the train can be stopped automatically when there is an intrusion of any animal or obstacle on the railway track

How It Works

• LiDAR Sensor Placement: The LiDAR sensor is placed on the moving locomotive.
• Laser Pulse Emission: The emitted laser pulsed light wave from the LiDAR sensor hits the obstacle and bounces back.
• Signal Reception: The bounced signal is accessed by the acceptor in the LiDAR sensor.
• Signal Processing: The directed signal is augmented and directed towards STM32, allowing the sensor to pinpoint the blockade.

Responses to Detected Obstacles

• The obstacle can be alarmed by a horn sound.
• The speed of the locomotive can be gradually reduced and stopped.
