Driver assisting multi-camera system
Project introduction:
Sasken created a multi-camera driver assistance system for a car company.

The goal was to design a concept that would be as compact as possible while having good image processing capabilities and memory capacity. The concept also required high-quality image sensors to capture all information from traffic, such as road signs.
