Joe Tu, a promotions engineer at the ARTC
research development division, pointed out that
ARTC’s R&D direction leaned towards system
integration to improve the product’s competitiveness
and allow suppliers to get a leg-up in the global
market. System integration included considered
factors like combining optical designs (matrix LED
headlights and optical imaging design), image
process algorithm, embedded hardware, long-
range nighttime vehicle recognition, hardware and
software integration, and development verifi cation.

By fitting the headlight with a camera, ARTC
improves detection accuracy by using algorithms
to train the system and sensors to control how
the headlight beams react and to apply and block
light when detecting light sources. By applying and
blocking light when approaching opposite direction
or same-direction vehicles, ADB would help lessen
the headlight glare on the drivers and improve
lighting and driving conditions at night. Using the
