In the next section, we will explore how this wealth of data is utilized by Waymo’s self-driving car through the power of artificial intelligence algorithms.
The Lidar System
At the core of Waymo’s self-driving technology is the sophisticated Lidar system. Lidar, which stands for Light Detection and Ranging, plays a crucial role in enabling the vehicle to sense its surroundings with exceptional precision.
The Lidar system functions by emitting laser beams in different directions and measuring the time it takes for the reflected light to return. This allows the vehicle to construct a detailed and accurate 3D map of its environment. The emitted laser beams capture information about the distance, shape, and position of objects, ensuring that the self-driving car has a comprehensive understanding of its surroundings.
Waymo’s Lidar system utilizes a combination of mechanical and solid-state technology to achieve remarkable performance. It comprises a rotating platform that houses multiple laser emitters and sensors. As the platform spins, the laser beams are emitted and rapidly scanned across the environment, covering a wide range of angles. The sensors then capture the backscattered light and convert it into data that can be processed by the vehicle’s computer system.
One of the key advantages of Lidar technology is its ability to create a highly accurate and detailed 3D representation of the environment. By measuring the time it takes for the laser beams to bounce back, Lidar can precisely determine the distance between the vehicle and surrounding objects, enabling it to detect and classify pedestrians, cyclists, vehicles, and various other obstacles with remarkable accuracy.
Furthermore, the Lidar system provides the vehicle with a real-time understanding of the environment, allowing it to adapt to dynamic situations on the road.
