Sensors for current and
future vehicle systems:
Understanding ADAS sensors, part 1
Diving into the technology behind cameras, lidar, infrared cameras, radar sensors,
acoustic sensors, and others used in advanced driver assistance systems.
By Scott Brown, Technical Editor
T
he advanced driver assistance systems
(ADAS) of today are supported by various
sensors and are paving the way toward future
automation in next-generation vehicles. You've likely
encountered these systems where service operations
required you to perform additional operations
to maintain system integrity to support proper
operation. These sensors could include cameras,
infrared cameras, lidar (light, detection, and ranging),
radar, and ultrasonic sensors. In this two-part
article, we will take a closer look at different types
of ADAS sensors and discuss how they are used to
support ADAS and ultimately, SAE J3016 Level-5,
fully autonomous vehicles.
CAMERAS
For at least the last decade we've seen most manufacturers
deploy forward-facing cameras on some of
their vehicles. The very early systems classified as
SAE J3016 Level-0, mainly provided warnings for
lane departure and potential collision events with
vulnerable road users (VRUs). As computer vision
(CV) technology advanced, ADAS became far more
capable. CV and artificial intelligence (AI) brought
forward artificial neural networks (ANNs) capable
of identifying the environment around the vehicle
with object detection, classification, body pose detection,
semantic segmentation, character recognition,
and more, typically based upon industry standard
" common objects in context " (COCO) datasets used
for training perception networks.
Today's advanced driver assistance systems (ADAS) are supported by various sensors
and are paving the way toward future automation in next-generation vehicles.

DIGITAL CAMERA BASICS
A digital camera collects the light rays reflected from
objects within the camera's field of view (FOV) which
are passed through a series of concave and convex glass
elements that make up the lens. Light rays passing
