What are ADAS Cameras used for?

The ADAS (Advanced Driver Assistance System) on a dashcam serves several purposes. It is a system that can alert the driver in certain emergency situations. It closely monitors the road to detect any lack of driver attention. ADAS typically includes individual features that can be enabled or disabled:

FCWS (Forward Collision Warning System): This system provides warnings when a vehicle ahead is rapidly approaching, such as in cases of traffic congestion. The dashcam uses visual sensors and GPS data to assess the severity of the situation and issue warnings accordingly.

LDWS (Lane Departure Warning System): The LDWS alerts the driver when the vehicle is about to unintentionally veer out of the current lane, providing timely warnings.

FVSA (Front Vehicle Start Alarm): When the front vehicle starts moving while the driver's vehicle remains stationary, this system alerts the driver.

Some ADAS systems can provide additional warnings. For example, Mio dashcams have a fatigue alarm that alerts the driver when they have been driving continuously for an extended period, indicating that it might be a good time to take a break and rest.

Advanced Driver Assistance Systems

A safety warning system that provides audio alerts for Lane Departure Warning (LDWS), Forward Collision Warning (FCWS), and Front Vehicle Departure Warning (FVDW). It can detect road markings and issue voice warnings to the driver when the vehicle begins to deviate from the lane or faces an imminent collision risk.

Lane Departure Warning System

The LDWS utilizes camera lenses and GPS signals to monitor the road lanes in real-time. If the driver falls asleep or drives improperly, causing the vehicle to deviate from the lane, preset warning sounds will be activated.

Forward Collision Warning System

The FCWS calculates the average distance to the preceding vehicle and provides advanced reminders to the driver when it reaches the safe braking distance range, helping to prevent collisions.

Front Vehicle Departure Warning

The Front Vehicle Departure Warning is an intelligent system that issues warnings when the front vehicle departs from a stationary position, aiding the driver.

Side View Camera

Installation Position: Left and right side mirrors or the lower part of the vehicle body. The side view camera is primarily used for blind spot detection (BSD) and can provide either a forward or rearward view depending on its installation position. Currently, most car manufacturers choose to install it below the side mirrors on both sides of the vehicle. In the future, it may potentially replace traditional rearview mirrors.

Rear View Camera

Installation Position: Typically mounted on the trunk or rear windshield. The rear view camera is primarily used during the reverse process to assist the driver in capturing the image behind the rear of the vehicle. It enables parking assistance functionality.

Front-Facing Camera Installation

Installation Position: Typically mounted on the windshield near the interior rearview mirror.

The front-facing camera, commonly referred to as the front camera, is used for forward driving assistance. Its main function is to identify vehicles and pedestrians ahead, with a field of view of approximately 45°. The image sensor, along with the dual-core MCU extended by DSP, processes incoming video frames to monitor the road ahead. It enables driving assistance features such as Forward Collision Warning (FCW), Lane Departure Warning (LDW), and Adaptive Cruise Control (ACC). Additionally, emerging night vision cameras are often integrated into this module.

Introduction to ADAS Camera Classification and Functions

Front-facing cameras are commonly either single or dual-lens cameras. Dual-lens cameras offer better distance measurement performance but require more complex algorithms and come at a higher price. The number of cameras in the front-facing camera module may vary. For example, Tesla vehicles are equipped with three cameras:

Narrow field of view front camera with a maximum monitoring distance of 250 meters;

Primary field of view front camera with a maximum monitoring distance of 150 meters;

Wide field of view front camera with a maximum monitoring distance of 60 meters.

The front-facing camera serves as the core camera for ADAS, encompassing distance measurement, object recognition, road line detection, and other functionalities. Therefore, it requires complex algorithms and has a higher barrier to entry.

How ADAS cameras work

ADAS cameras capture images of the vehicle's surroundings and analyze them using computer vision technology. They can detect road markings, identify other vehicles and pedestrians, determine distance and speed, and more. Based on this data, the system can provide corresponding warning and assistance functions to the driver.

Surround View Camera

Installation Position: Vehicle front and rear emblems (or nearby) and a set of cameras integrated into the left and right side mirrors.

The surround view camera, also known as a panoramic imaging monitoring system, is used to identify parking lane markings, road conditions, and the surrounding vehicle situation. It uses multiple cameras to stitch images together to provide a 360-degree view of the vehicle. Due to the need for detecting the surroundings of the vehicle, it is usually installed in positions such as the front emblem or grille.

What are the options for installing ADAS cameras?

ADAS cameras are usually mounted on the vehicle's front windshield to ensure it has a good field of view and angle. Some cameras may also be mounted on the side mirrors or rear to monitor blind spots.
