Camera based ADAS for mass deployments

June 21, 2012 | Benno Kusstatscher, Peter Voss | 222902323
Camera based ADAS for mass deployments Advanced Driver Assistance Systems (ADAS) will see a steep growth in the years to come. One driving factor for sure is the increased safety awareness and the desire for more driving comfort on the customer side. But first and foremost Euro NCAP's tightened safety requirements will boost installed ADAS equipment from single digit take rates to almost 100% over the next years. Hence it's to no surprise that the call for a commercially viable solution is on.

This is to satisfy new deployments as high volume standard equipment vs. the moderate customer option business as seen today. Analog Devices recently announced a new ADAS Processor Family, the Blackfin ADSP-BF60x series which was developed for this emerging mass market requirement. The first two processors of this new family are available now to service this new requirement for camera based solutions.

Depending on the ADAS tasks to solve, different types of sensors are being deployed in systems today. For the environmental near and far-field monitoring around the vehicle, Radar-, Ultrasonic-, LIDAR-, PMD-, Camera- and Night camera sensors are used either as single or multi sensor systems. The latter combine the sensor data to achieve more accurate results as desired. Camera systems will further see an additional boost, looking inside the car for analyzing the driver's state. Driver situation and prediction analysis will be used to better filter the various warning messages an ADAS system can generate in the future. The goal is not to overflow the driver with irrelevant warnings. If the system detects that a sporty driver is concentrating on the traffic in front of him, a premature warning of a car he is following might be very annoying. However, knowing that the driver is distracted while playing with his mobile phone or simply is about to fall asleep, an early enough warning or even braking action in the same situation might be very appropriate.
