摘要

The visual based Lane Departure Warning System (LDWS) is one of the emerging systems for reducing traffic accidents. In this paper, we extend our peak-finding based lane detection algorithm and the spatiotemporal based dual warning mechanisms to an integrated H/S co-design system. The proposed digital hardware scheme was built by extracting the regular high-computation modules from the entire LDWS algorithm. An innovative buffering circuit design, the Vertical Shifter (VS), is presented to speed up the in-circuit communication time. The whole system has been developed in an FPGA platform embedded with Nios II processor. Generally, our integrated H/S LDWS is capable of more flexible control capability associated with novel hardware accelerator in a system on a programmable chip (SOPC).
