Abstract :
A low computing cost obstacle detection technique based on the stereo motion principle is presented. The process followed is based on the height estimation of world objects from the analysis of the height of the regions defined by the objects in a sequence of images. Only the regions that are located within the transitional zone and have a different aspect with respect to the transitional path (the potential obstacle regions), are analysed along the image sequence
