A system architecture for IP-camera based driver assistance applications

We present a novel system architecture for automotive IP-camera based driver assistance applications. We assume that the video data is carried by an in-car switched IP/Ethernet network. The proposed architecture borrows concepts from the CE industry and hence fully takes advantage of the corresponding price and performance advantages. As an implementation study, a top view service is investigated. The suitability of the proposed approach is evaluated by introducing performance measures reflecting the special requirements of the driver assistance domain. To meet the real-time requirements of the driver assistance services we investigate and compare different architectural approaches for IP network cameras. Based on the results obtained with the prototypical implementations, an appropriate solution for future IP-camera based driver assistance services is proposed.
