Abstract :
A low cost autonomous vision system for real-time applications in natural environments has been realized. It encompasses a 160 by 128 pixel 120 dB dynamic range vision sensor performing contrast magnitude and direction computation at the pixel level (Ruedi, 2003), a BF 533 BlackFin processor, memory and a low data rate RF link usable to communicate the high level information extracted from the scene to a network of such devices. Used to implement a road marking detection algorithm, it proved to perform reliably at 25 frames per second in highly changing conditions ranging from night to sun in the field of view
