This paper describes a vision-based overtaking vehicle detection method for driver assistance systems and its implementation using IMAPCAR, a highly parallel SIMD linear array processor. The proposed overtaking vehicle detection method is based on optical flows detected by block-matching using SAD. As a result, IMAPCAR enables video-rate (33fram/s) implementation of overtaking vehicle detection, and is also 66 to 132 times more power efficient than a 3 GHz general-purpose processor.
