ADAS cameras (Advanced Driver Assistance Systems cameras) play a crucial role in modern vehicles, enhancing safety and assisting drivers. Let’s delve into how they work:

1. Types of ADAS Cameras:
   • Forward-Facing Cameras: These are the most common type. They are mounted inside the vehicle’s windshield, near the rear-view mirror. Forward cameras provide data for several ADAS systems:
     • Lane Departure Warning: Tracks road markings.
     • Lane Keeping Assist: Monitors lane markings and the forward path.
     • Road Departure Mitigation: Detects road edge markings.
     • Traffic Sign Recognition: Identifies traffic signs (some vehicles have a dedicated camera for this).
     • Forward Collision Warning: Looks for obstructions.
     • Automatic Emergency Braking: Measures distance to the next vehicle.
     • Adaptive Cruise Control: Gauges distance to the next vehicle.
     • Pedestrian Detection: Identifies pedestrians.
     • Automatic High Beams: Adjusts based on light levels and detects other vehicles.
   • Side and Rear-Mounted Cameras: These are becoming more common. They provide data for various ADAS applications:
     • Parking Assistance
     • Blind Spot Detection
     • Cross Traffic Alert (both rear and forward)
     • Around View Monitoring
2. How ADAS Cameras Work:
   • Image Capture: ADAS cameras capture images of the scene.
   • Object Identification: The computer processes these images to identify objects in the environment.
   • Distance Estimation: Algorithms track these objects and determine their distance from the car.
   • Decision-Making: This information informs the ADAS system’s decisions, such as initiating emergency braking or steering away from potential collisions¹.

In summary, ADAS cameras use sensors to detect objects, process information, and assist in making split-second decisions to enhance driver safety and prevent accidents.
