Lidar – the Main Sensor of the Vision System of Self-driving Vehicles

The speaker will talk about the lidar, a laser scanner that sends millions of pulses per second in different directions around itself. By determining the time between the emission of the impulse and its return after reflection, the device, knowing the speed of light, determines the distance to surrounding objects. The result is so-called point clouds, from which high-resolution 3D maps are constructed. This data is used to train neural networks to build optimal trajectories for cars and robots, as well as for direct online obstacle detection.
