Lidar in drones is responsible for scanning space using laser beams, which are reflected from objects and create a three-dimensional picture of the environment. This is the most expensive car equipment with an autopilot.
Yandex has developed two types of lidars: the first has a 360-degree view, and the second, solid-state, that is, based on an integrated circuit and without moving parts, is 120 degrees. It is needed to obtain more detailed information about the objects along the drone. For example, such a sensor is able to distinguish a pedestrian from a cyclist even at a distance of 200 meters.
