Abstract

Nowadays, the railways transport operators require anticipated obstacles detection on the tracks in order to avoid collisions. Such a system allows to : - reduce the wasting of time of exploitation linked to the incidents; - reduce travelling and waiting times for the passengers; - improve passengers safety. In our system, we use optical sensors to detect the obstacles. Two matrix video cameras are installed in front of an automatic train in order to have two simultaneous views of the tracks. This configuration of artificial vision, called stereo vision, allows us to recover the three-dimensional scene in front of the trai
