A Light Detection and Ranging (LIDAR) is a device fitted with a laser emitter capable of measuring distances with high accuracy. In the automotive industry, with the advent of autonomous cars, manufacturers are using the LIDAR system as an advanced driver assistance system. Swedish automobile brand Volvo for example, has already announced that its next generation of cars, beginning with the new XC90 in 2022, will use this technology developed by  Luminar.<\/p>\n\n\n\n

What an automobile LIDAR system does is that it constructs a 3D model of the path ahead of the car and conducts the necessary computations to interact with that environment by emitting millions of points of laser light. <\/p>\n\n\n\n

In this guide about LIDAR for autonomous vehicles, we will take a look at the applications of LIDAR in autonomous driving and the pros and cons of LIDAR in cars.<\/p>\n\n\n\n

How Does LIDAR Work in Cars<\/h2>\n\n\n\n

A lidar sensor uses a laser to send infrared light waves into the surroundings. These light pulses bounce off nearby objects and return to the sensor, which calculates the time it takes for them to return.  From the information or data acquired by the LIDAR system, the sensor builds a map of 3D points which creates and captures an image of the car’s surroundings.<\/p>\n\n\n\n
