How does Lidar Work on Self Driving Cars?

#shorts
Lidar
Light Imaging Detection and Ranging (LIDAR) uses laser light pulses to scan the environment, as opposed to radar’s radio waves. Lidar works by firing millions of laser signals per second, which are then reflected off object surfaces and returned to a receiver, which creates a 3D model of the car’s surroundings.
Strengths of lidar:
Lidar can see in higher resolution than radar. It’s capable of knowing whether a pedestrian is facing forwards or backward or whether a two-wheeled vehicle is a bike or a motorcycle, allowing the car’s computer to better predict how any given object will behave.
Limitations of lidar:
At present, lidar is the most expensive sensor option for carmakers and, because sensors are often spinning, require more moving parts. This means there are more opportunities for something to go wrong. Lidar is also limited by weather conditions. It won’t work in fog or dust, which requires vehicles with lidar technology to have a secondary sensor.
