Automotive challenges (& opportunities)
Copyright © 2016 videantis GmbH 28
• Cold & hot: low power
• Dark & light: HDR, noise
• Dirty lens: detect algos
• 0-120mph: different algos
• Car loaded/dinged: calibrate
• … and many more
Challenge: work under all conditions…

Challenge: under severe power constraints…
Power source
100kW
Small form
factors limits
heat dissipation

Central processing
• Pros
• Single processing platform
eases software dev
• Cons
• Entry-level car also needs
high-end head unit
• Not scalable, not modular
• Adding cameras causes
system overload
Challenge: central or distributed processing?
Central processing uses expensive
head unit, even in low-end car
Copyright © 2016 videantis GmbH 31
Distributed processing
• Pros
• Low-end head unit
• Options become plug-and-
play
• Every camera adds
processing capabilities
• Cons
• More complex system
This is reality today:
• Some cars have 250 ECUs
Scalable architecture provides
most flexibility, lowest entry cost
Challenge: central or distributed processing?

• Business opportunity is huge: >$1T
• Self-driving car tech causes paradigm shift
• New players can grab market share
• Automotive is not like consumer electronics
• Next 10 years no self-driving cars:
• change will be gradual, lots of driver
assist functions with vision technologies
• Efficient computer vision systems are the
key enabler for making our cars safer
