Camera Systems

Definition

Camera systems are sophisticated devices used to capture visual information, enabling perception in autonomous vehicles. These systems typically consist of multiple cameras that provide a 360-degree view, which is critical for detecting and understanding the vehicle's surroundings, including obstacles, lane markings, and traffic signals. They play an essential role in the overall perception algorithms that inform planning and control strategies for safe navigation.
