What is lidar?

Lidar (light detection and ranging) uses eye-safe laser beams to “see” the world in 3D, providing machines and computers an ultra accurate representation of the surveyed environment.

How does lidar work?



A typical lidar sensor emits pulsed light waves into the surrounding environment.



These pulses bounce off surrounding objects and return to the sensor.



The sensor uses the time it took for each pulse to return to the sensor to calculate the distance it traveled.

Lidar data from a train station, where it is used to help manage the flow of pedestrians, monitor for safety and overcrowding, and collect analytics which will better inform future station planning and management.
