n the first part of this article,
we discussed some of
the types of computer vision
(CV) sensors used in modern
cars. These included cameras, timeof-flight
cameras, and stereo cameras.
In this second and final part of the article,
we will take a closer look at thermal
imaging, ultrasonics, and radar.
Looking at the New Car Assessment
Programs (NCAP) for both the U.S. and
regions of Europe is a good indicator of
where the market is heading regarding
vehicle safety systems. The sensors that
we will likely see more of are thermal/
infrared-based cameras.
The standards that drove the capabilities
of today's vehicles fall short in
demanding performance requirements
around protecting vulnerable road users
(VRUs) at night where an overwhelming
majority of the vehicle to VRU
injuries and deaths occur. The reason
is primarily driven by the current state
of the market's technological capabilities.
However, regulators are moving the

industry toward creating incentives to
bring low-light VRU protections to market.
There is no doubt in my mind that
we will continue to see a rise in onboard
perception systems with tremendous
capabilities. And because of this, we as
service professionals need to maintain
high-level situational awareness of these
technologies and how service operations
should be properly performed on tomorrow's
vehicles.
Both the U.S. and European NCAPs
vary in requirements. In both markets,
